Release Notes
=============
-* 9 "Plain Nine"
+* 0.10 "Freedom" January, 2012
+
General notes
-------------
+See the Changelog file for a list of significant changes. Note, there
+are many more new features and bugfixes than whats listed there.
-From this release onwards, we have decided to drop the leading zero from our
-release numbers. There were no plans of ever changing it, so it carried no
-information. Thus this release is just a plain 9, the next will be 10 etc.
-
-A new library arrived in Libav during this development cycle -- its name is
-libavresample and it handles audio conversion and mixing. All users are
-encouraged to use it instead of the old, now deprecated, audio conversion
-API in libavcodec.
-
-The libpostproc library now resides in a separate tree. It was fully independent
-of the other Libav libraries, not used by any of the tools and saw very little
-development. For these reasons we decided that it has no place in Libav. A
-standalone Git tree is available at http://git.videolan.org/?p=libpostproc.git
-for people wishing to use libpostproc.
-
-The major versions of the libavcodec, libavformat and libavfilter libraries have
-been bumped, so they are not API or ABI compatible with the 0.8 release. The
-ffmpeg transcoding tool, kept for compatibility in 0.8, has also been dropped.
-
-This release brings a number of significant changes in the libavfilter library.
-Firstly, all the API dealing with filter internals is no longer public. The
-result is that creating user-side filters will not be supported until
-libavfilter is more mature.
-Secondly, full audio filtering support is now available along with a set of
-basic audio filters. We hope that their number will soon grow significantly.
-The avconv transcoding tool has of course been extended to handle audio
-filtering as well.
-There were a number of other API changes, most importantly the addition of
-the buffer sink public API.
-
-In the libavcodec library, one of the most notable changes is added support for
-planar audio (i.e. not interleaved). Many decoders and encoders, that previously
-did inefficient (de)interleaving internally, now only work with planar audio
-formats. Libavresample can be used for optimized conversion between interleaved
-and planar formats.
-
-As usual, this release also contains support for some new formats, many smaller
-new features and countless bug fixes. We can highlight Opus decoding / encoding
-through libopus, encoders for Apple ProRes and Ut Video, WMA Lossless and
-RealAudio Lossless decoders, fragmented MOV/MP4 and ISMV (Smooth Streaming)
-muxers, a large number of RTMP improvements and support for cover art in
-ID3v2, WMA, MP4 and FLAC.
-
-See the Changelog file for a list of significant changes.
-
-Please note that our policy on bug reports has not changed. We still only accept
-bug reports against HEAD of the Libav trunk repository. If you are experiencing
-issues with any formally released version of Libav, please try a current version
-of the development code to check if the issue still exists. If it does, make
-your report against the development code following the usual bug reporting
+Bugreports against FFmpeg git master or the most recent FFmpeg release are
+accepted. If you are experiencing issues with any formally released version of
+FFmpeg, please try git master to check if the issue still exists. If it does,
+make your report against the development code following the usual bug reporting
guidelines.
-
-
-API changes
------------
-
-A number of additional APIs have been introduced and some existing functions
-have been deprecated and are scheduled for removal in the next release.
-Significant API changes include:
-
-[libavcodec]:
-* New video encoding API, similar to the previously introduced audio encoding
- API, which encodes from an AVFrame to an AVPacket, thus allowing it to
- properly output timing information and side data.
-
-* All CODEC_ID_* symbols now carry AV_ prefixes. Non-prefixed codec IDs are
- deprecated.
-
-* New codec descriptor API, which allows getting the properties of a given codec
- (identified by its ID), without referring to a specific decoder or encoder.
-
-* An AVFrame must now be freed with a dedicated function, avcodec_free_frame().
-
-[libavutil]:
-* New audio FIFO API, which simplifies managing/merging/splitting audio buffers.
-
-* new int/float type punning API
-
-[libavfilter]:
-* All filter internals were hidden.
-
-* audio filtering.
-
-* new buffer sink API for getting frames out of libavfilter.
-
-Please see the file doc/APIchanges for details along with similar
-programmer-centric information.

-@chapter Synopsis
-
-The generic syntax is:
-
-@example
-@c man begin SYNOPSIS
-avconv [global options] [[infile options][@option{-i} @var{infile}]]... @{[outfile options] @var{outfile}@}...
-@c man end
-@end example
-
-@chapter Description
-@c man begin DESCRIPTION
-
-avconv is a very fast video and audio converter that can also grab from
-a live audio/video source. It can also convert between arbitrary sample
-rates and resize video on the fly with a high quality polyphase filter.
-
-avconv reads from an arbitrary number of input "files" (which can be regular
-files, pipes, network streams, grabbing devices, etc.), specified by the
-@code{-i} option, and writes to an arbitrary number of output "files", which are
-specified by a plain output filename. Anything found on the command line which
-cannot be interpreted as an option is considered to be an output filename.
-
-Each input or output file can in principle contain any number of streams of
-different types (video/audio/subtitle/attachment/data). Allowed number and/or
-types of streams can be limited by the container format. Selecting, which
-streams from which inputs go into output, is done either automatically or with
-the @code{-map} option (see the Stream selection chapter).
-
-To refer to input files in options, you must use their indices (0-based). E.g.
-the first input file is @code{0}, the second is @code{1} etc. Similarly, streams
-within a file are referred to by their indices. E.g. @code{2:3} refers to the
-fourth stream in the third input file. See also the Stream specifiers chapter.
-
-As a general rule, options are applied to the next specified
-file. Therefore, order is important, and you can have the same
-option on the command line multiple times. Each occurrence is
-then applied to the next input or output file.
-Exceptions from this rule are the global options (e.g. verbosity level),
-which should be specified first.
-
-Do not mix input and output files -- first specify all input files, then all
-output files. Also do not mix options which belong to different files. All
-options apply ONLY to the next input or output file and are reset between files.
-
-@itemize
-@item
-To set the video bitrate of the output file to 64kbit/s:
-@example
-avconv -i input.avi -b 64k output.avi
-@end example
-
-@item
-To force the frame rate of the output file to 24 fps:
-@example
-avconv -i input.avi -r 24 output.avi
-@end example
-
-@item
-To force the frame rate of the input file (valid for raw formats only)
-to 1 fps and the frame rate of the output file to 24 fps:
-@example
-avconv -r 1 -i input.m2v -r 24 output.avi
-@end example
-@end itemize
-
-The format option may be needed for raw input files.
-
-@c man end DESCRIPTION
-
-@chapter Detailed description
-@c man begin DETAILED DESCRIPTION
-
-The transcoding process in @command{avconv} for each output can be described by
-the following diagram:
-
-@example
- _______ ______________ _________ ______________ ________
-| | | | | | | | | |
-| input | demuxer | encoded data | decoder | decoded | encoder | encoded data | muxer | output |
-| file | ---------> | packets | ---------> | frames | ---------> | packets | -------> | file |
-|_______| |______________| |_________| |______________| |________|
-
-@end example
-
-@command{avconv} calls the libavformat library (containing demuxers) to read
-input files and get packets containing encoded data from them. When there are
-multiple input files, @command{avconv} tries to keep them synchronized by
-tracking lowest timestamp on any active input stream.
-
-Encoded packets are then passed to the decoder (unless streamcopy is selected
-for the stream, see further for a description). The decoder produces
-uncompressed frames (raw video/PCM audio/...) which can be processed further by
-filtering (see next section). After filtering the frames are passed to the
-encoder, which encodes them and outputs encoded packets again. Finally those are
-passed to the muxer, which writes the encoded packets to the output file.
-
-@section Filtering
-Before encoding, @command{avconv} can process raw audio and video frames using
-filters from the libavfilter library. Several chained filters form a filter
-graph. @command{avconv} distinguishes between two types of filtergraphs -
-simple and complex.
-
-@subsection Simple filtergraphs
-Simple filtergraphs are those that have exactly one input and output, both of
-the same type. In the above diagram they can be represented by simply inserting
-an additional step between decoding and encoding:
-
-@example
- _________ __________ ______________
-| | | | | |
-| decoded | simple filtergraph | filtered | encoder | encoded data |
-| frames | -------------------> | frames | ---------> | packets |
-|_________| |__________| |______________|
-
-@end example
-
-Simple filtergraphs are configured with the per-stream @option{-filter} option
-(with @option{-vf} and @option{-af} aliases for video and audio respectively).
-A simple filtergraph for video can look for example like this:
-
-@example
- _______ _____________ _______ _____ ________
-| | | | | | | | | |
-| input | ---> | deinterlace | ---> | scale | ---> | fps | ---> | output |
-|_______| |_____________| |_______| |_____| |________|
-
-@end example
-
-Note that some filters change frame properties but not frame contents. E.g. the
-@code{fps} filter in the example above changes number of frames, but does not
-touch the frame contents. Another example is the @code{setpts} filter, which
-only sets timestamps and otherwise passes the frames unchanged.
-
-@subsection Complex filtergraphs
-Complex filtergraphs are those which cannot be described as simply a linear
-processing chain applied to one stream. This is the case e.g. when the graph has
-more than one input and/or output, or when output stream type is different from
-input. They can be represented with the following diagram:
-
-@example
- _________
-| |
-| input 0 |\ __________
-|_________| \ | |
- \ _________ /| output 0 |
- \ | | / |__________|
- _________ \| complex | /
-| | | |/
-| input 1 |---->| filter |\
-|_________| | | \ __________
- /| graph | \ | |
- / | | \| output 1 |
- _________ / |_________| |__________|
-| | /
-| input 2 |/
-|_________|
-
-@end example
-
-Complex filtergraphs are configured with the @option{-filter_complex} option.
-Note that this option is global, since a complex filtergraph by its nature
-cannot be unambiguously associated with a single stream or file.
-
-A trivial example of a complex filtergraph is the @code{overlay} filter, which
-has two video inputs and one video output, containing one video overlaid on top
-of the other. Its audio counterpart is the @code{amix} filter.
-
-@section Stream copy
-Stream copy is a mode selected by supplying the @code{copy} parameter to the
-@option{-codec} option. It makes @command{avconv} omit the decoding and encoding
-step for the specified stream, so it does only demuxing and muxing. It is useful
-for changing the container format or modifying container-level metadata. The
-diagram above will in this case simplify to this:
-
-@example
- _______ ______________ ________
-| | | | | |
-| input | demuxer | encoded data | muxer | output |
-| file | ---------> | packets | -------> | file |
-|_______| |______________| |________|
-
-@end example
-
-Since there is no decoding or encoding, it is very fast and there is no quality
-loss. However it might not work in some cases because of many factors. Applying
-filters is obviously also impossible, since filters work on uncompressed data.
-
-@c man end DETAILED DESCRIPTION
-
-@chapter Stream selection
-@c man begin STREAM SELECTION
-
-By default avconv tries to pick the "best" stream of each type present in input
-files and add them to each output file. For video, this means the highest
-resolution, for audio the highest channel count. For subtitle it's simply the
-first subtitle stream.
-
-You can disable some of those defaults by using @code{-vn/-an/-sn} options. For
-full manual control, use the @code{-map} option, which disables the defaults just
-described.
-
-@c man end STREAM SELECTION
-
-@chapter Options
-@c man begin OPTIONS
-
-@include avtools-common-opts.texi
-
-@section Main options
-
-@table @option
-
-@item -f @var{fmt} (@emph{input/output})
-Force input or output file format. The format is normally autodetected for input
-files and guessed from file extension for output files, so this option is not
-needed in most cases.
-
-@item -i @var{filename} (@emph{input})
-input file name
-
-@item -y (@emph{global})
-Overwrite output files without asking.
-
-@item -c[:@var{stream_specifier}] @var{codec} (@emph{input/output,per-stream})
-@itemx -codec[:@var{stream_specifier}] @var{codec} (@emph{input/output,per-stream})
-Select an encoder (when used before an output file) or a decoder (when used
-before an input file) for one or more streams. @var{codec} is the name of a
-decoder/encoder or a special value @code{copy} (output only) to indicate that
-the stream is not to be reencoded.
-
-For example
-@example
-avconv -i INPUT -map 0 -c:v libx264 -c:a copy OUTPUT
-@end example
-encodes all video streams with libx264 and copies all audio streams.
-
-For each stream, the last matching @code{c} option is applied, so
-@example
-avconv -i INPUT -map 0 -c copy -c:v:1 libx264 -c:a:137 libvorbis OUTPUT
-@end example
-will copy all the streams except the second video, which will be encoded with
-libx264, and the 138th audio, which will be encoded with libvorbis.
-
-@item -t @var{duration} (@emph{output})
-Stop writing the output after its duration reaches @var{duration}.
-@var{duration} may be a number in seconds, or in @code{hh:mm:ss[.xxx]} form.
-
-@item -fs @var{limit_size} (@emph{output})
-Set the file size limit.
-
-@item -ss @var{position} (@emph{input/output})
-When used as an input option (before @code{-i}), seeks in this input file to
-@var{position}. When used as an output option (before an output filename),
-decodes but discards input until the timestamps reach @var{position}. This is
-slower, but more accurate.
-
-@var{position} may be either in seconds or in @code{hh:mm:ss[.xxx]} form.
-
-@item -itsoffset @var{offset} (@emph{input})
-Set the input time offset in seconds.
-@code{[-]hh:mm:ss[.xxx]} syntax is also supported.
-The offset is added to the timestamps of the input files.
-Specifying a positive offset means that the corresponding
-streams are delayed by @var{offset} seconds.
-
-@item -metadata[:metadata_specifier] @var{key}=@var{value} (@emph{output,per-metadata})
-Set a metadata key/value pair.
-
-An optional @var{metadata_specifier} may be given to set metadata
-on streams or chapters. See @code{-map_metadata} documentation for
-details.
-
-This option overrides metadata set with @code{-map_metadata}. It is
-also possible to delete metadata by using an empty value.
-
-For example, for setting the title in the output file:
-@example
-avconv -i in.avi -metadata title="my title" out.flv
-@end example
-
-To set the language of the first audio stream:
-@example
-avconv -i INPUT -metadata:s:a:0 language=eng OUTPUT
-@end example
-
-@item -target @var{type} (@emph{output})
-Specify target file type (@code{vcd}, @code{svcd}, @code{dvd}, @code{dv},
-@code{dv50}). @var{type} may be prefixed with @code{pal-}, @code{ntsc-} or
-@code{film-} to use the corresponding standard. All the format options
-(bitrate, codecs, buffer sizes) are then set automatically. You can just type:
-
-@example
-avconv -i myfile.avi -target vcd /tmp/vcd.mpg
-@end example
-
-Nevertheless you can specify additional options as long as you know
-they do not conflict with the standard, as in:
-
-@example
-avconv -i myfile.avi -target vcd -bf 2 /tmp/vcd.mpg
-@end example
-
-@item -dframes @var{number} (@emph{output})
-Set the number of data frames to record. This is an alias for @code{-frames:d}.
-
-@item -frames[:@var{stream_specifier}] @var{framecount} (@emph{output,per-stream})
-Stop writing to the stream after @var{framecount} frames.
-
-@item -q[:@var{stream_specifier}] @var{q} (@emph{output,per-stream})
-@itemx -qscale[:@var{stream_specifier}] @var{q} (@emph{output,per-stream})
-Use fixed quality scale (VBR). The meaning of @var{q} is
-codec-dependent.
-
-@item -filter[:@var{stream_specifier}] @var{filter_graph} (@emph{output,per-stream})
-@var{filter_graph} is a description of the filter graph to apply to
-the stream. Use @code{-filters} to show all the available filters
-(including also sources and sinks).
-
-See also the @option{-filter_complex} option if you want to create filter graphs
-with multiple inputs and/or outputs.
-@item -pre[:@var{stream_specifier}] @var{preset_name} (@emph{output,per-stream})
-Specify the preset for matching stream(s).
-
-@item -stats (@emph{global})
-Print encoding progress/statistics. On by default.
-
-@item -attach @var{filename} (@emph{output})
-Add an attachment to the output file. This is supported by a few formats
-like Matroska for e.g. fonts used in rendering subtitles. Attachments
-are implemented as a specific type of stream, so this option will add
-a new stream to the file. It is then possible to use per-stream options
-on this stream in the usual way. Attachment streams created with this
-option will be created after all the other streams (i.e. those created
-with @code{-map} or automatic mappings).
-
-Note that for Matroska you also have to set the mimetype metadata tag:
-@example
-avconv -i INPUT -attach DejaVuSans.ttf -metadata:s:2 mimetype=application/x-truetype-font out.mkv
-@end example
-(assuming that the attachment stream will be third in the output file).
-
-@item -dump_attachment[:@var{stream_specifier}] @var{filename} (@emph{input,per-stream})
-Extract the matching attachment stream into a file named @var{filename}. If
-@var{filename} is empty, then the value of the @code{filename} metadata tag
-will be used.
-
-E.g. to extract the first attachment to a file named 'out.ttf':
-@example
-avconv -dump_attachment:t:0 out.ttf INPUT
-@end example
-To extract all attachments to files determined by the @code{filename} tag:
-@example
-avconv -dump_attachment:t "" INPUT
-@end example
-
-Technical note -- attachments are implemented as codec extradata, so this
-option can actually be used to extract extradata from any stream, not just
-attachments.
-
-@end table
-
-@section Video Options
-
-@table @option
-@item -vframes @var{number} (@emph{output})
-Set the number of video frames to record. This is an alias for @code{-frames:v}.
-@item -r[:@var{stream_specifier}] @var{fps} (@emph{input/output,per-stream})
-Set frame rate (Hz value, fraction or abbreviation).
-
-As an input option, ignore any timestamps stored in the file and instead
-generate timestamps assuming constant frame rate @var{fps}.
-
-As an output option, duplicate or drop input frames to achieve constant output
-frame rate @var{fps} (note that this actually causes the @code{fps} filter to be

-@item -map [-]@var{input_file_id}[:@var{stream_specifier}][,@var{sync_file_id}[:@var{stream_specifier}]] | @var{[linklabel]} (@emph{output})
-
-Designate one or more input streams as a source for the output file. Each input
-stream is identified by the input file index @var{input_file_id} and
-the input stream index @var{input_stream_id} within the input
-file. Both indices start at 0. If specified,
-@var{sync_file_id}:@var{stream_specifier} sets which input stream
-is used as a presentation sync reference.
-
-The first @code{-map} option on the command line specifies the
-source for output stream 0, the second @code{-map} option specifies
-the source for output stream 1, etc.
-
-A @code{-} character before the stream identifier creates a "negative" mapping.
-It disables matching streams from already created mappings.
-
-An alternative @var{[linklabel]} form will map outputs from complex filter
-graphs (see the @option{-filter_complex} option) to the output file.
-@var{linklabel} must correspond to a defined output link label in the graph.
-
-For example, to map ALL streams from the first input file to output
-@example
-avconv -i INPUT -map 0 output
-@end example
-
-For example, if you have two audio streams in the first input file,
-these streams are identified by "0:0" and "0:1". You can use
-@code{-map} to select which streams to place in an output file. For
-example:
-@example
-avconv -i INPUT -map 0:1 out.wav
-@end example
-will map the input stream in @file{INPUT} identified by "0:1" to
-the (single) output stream in @file{out.wav}.
-
-For example, to select the stream with index 2 from input file
-@file{a.mov} (specified by the identifier "0:2"), and stream with
-index 6 from input @file{b.mov} (specified by the identifier "1:6"),
-and copy them to the output file @file{out.mov}:
-@example
-avconv -i a.mov -i b.mov -c copy -map 0:2 -map 1:6 out.mov
-@end example
-
-To select all video and the third audio stream from an input file:
-@example
-avconv -i INPUT -map 0:v -map 0:a:2 OUTPUT
-@end example
-
-To map all the streams except the second audio, use negative mappings
-@example
-avconv -i INPUT -map 0 -map -0:a:1 OUTPUT
-@end example
-
-Note that using this option disables the default mappings for this output file.
-
-@item -map_metadata[:@var{metadata_spec_out}] @var{infile}[:@var{metadata_spec_in}] (@emph{output,per-metadata})
-Set metadata information of the next output file from @var{infile}. Note that
-those are file indices (zero-based), not filenames.
-Optional @var{metadata_spec_in/out} parameters specify, which metadata to copy.
-A metadata specifier can have the following forms:
-@table @option
-@item @var{g}
-global metadata, i.e. metadata that applies to the whole file
-
-@item @var{s}[:@var{stream_spec}]
-per-stream metadata. @var{stream_spec} is a stream specifier as described
-in the @ref{Stream specifiers} chapter. In an input metadata specifier, the first
-matching stream is copied from. In an output metadata specifier, all matching
-streams are copied to.
-
-@item @var{c}:@var{chapter_index}
-per-chapter metadata. @var{chapter_index} is the zero-based chapter index.
-
-@item @var{p}:@var{program_index}
-per-program metadata. @var{program_index} is the zero-based program index.
-@end table
-If metadata specifier is omitted, it defaults to global.
-
-By default, global metadata is copied from the first input file,
-per-stream and per-chapter metadata is copied along with streams/chapters. These
-default mappings are disabled by creating any mapping of the relevant type. A negative
-file index can be used to create a dummy mapping that just disables automatic copying.
-
-For example to copy metadata from the first stream of the input file to global metadata
-of the output file:
-@example
-avconv -i in.ogg -map_metadata 0:s:0 out.mp3
-@end example
-
-To do the reverse, i.e. copy global metadata to all audio streams:
-@example
-avconv -i in.mkv -map_metadata:s:a 0:g out.mkv
-@end example
-Note that simple @code{0} would work as well in this example, since global
-metadata is assumed by default.
-
-@item -map_chapters @var{input_file_index} (@emph{output})
-Copy chapters from input file with index @var{input_file_index} to the next
-output file. If no chapter mapping is specified, then chapters are copied from
-the first input file with at least one chapter. Use a negative file index to
-disable any chapter copying.
-@item -debug
-Print specific debug info.
-@item -benchmark (@emph{global})
-Show benchmarking information at the end of an encode.
-Shows CPU time used and maximum memory consumption.
-Maximum memory consumption is not supported on all systems,
-it will usually display as 0 if not supported.
-@item -timelimit @var{duration} (@emph{global})
-Exit after avconv has been running for @var{duration} seconds.
-@item -dump (@emph{global})
-Dump each input packet to stderr.
-@item -hex (@emph{global})
-When dumping packets, also dump the payload.
-@item -re (@emph{input})
-Read input at native frame rate. Mainly used to simulate a grab device.
-@item -vsync @var{parameter}
-Video sync method.
-
-@table @option
-@item passthrough
-Each frame is passed with its timestamp from the demuxer to the muxer.
-@item cfr
-Frames will be duplicated and dropped to achieve exactly the requested

-@item vfr
-Frames are passed through with their timestamp or dropped so as to
-prevent 2 frames from having the same timestamp.
-@item auto
-Chooses between 1 and 2 depending on muxer capabilities. This is the
-default method.
-@end table
-
-With -map you can select from which stream the timestamps should be
-taken. You can leave either video or audio unchanged and sync the
-remaining stream(s) to the unchanged one.
-
-@item -async @var{samples_per_second}
-Audio sync method. "Stretches/squeezes" the audio stream to match the timestamps,
-the parameter is the maximum samples per second by which the audio is changed.
--async 1 is a special case where only the start of the audio stream is corrected
-without any later correction.
-This option has been deprecated. Use the @code{asyncts} audio filter instead.
-@item -copyts
-Copy timestamps from input to output.
-@item -copytb
-Copy input stream time base from input to output when stream copying.
-@item -shortest (@emph{output})
-Finish encoding when the shortest input stream ends.
-@item -dts_delta_threshold
-Timestamp discontinuity delta threshold.
-@item -muxdelay @var{seconds} (@emph{input})
-Set the maximum demux-decode delay.
-@item -muxpreload @var{seconds} (@emph{input})
-Set the initial demux-decode delay.
-@item -streamid @var{output-stream-index}:@var{new-value} (@emph{output})
-Assign a new stream-id value to an output stream. This option should be
-specified prior to the output filename to which it applies.
-For the situation where multiple output files exist, a streamid
-may be reassigned to a different value.
-
-For example, to set the stream 0 PID to 33 and the stream 1 PID to 36 for
-an output mpegts file:
-@example
-avconv -i infile -streamid 0:33 -streamid 1:36 out.ts
-@end example
-
-@item -bsf[:@var{stream_specifier}] @var{bitstream_filters} (@emph{output,per-stream})
-Set bitstream filters for matching streams. @var{bistream_filters} is
-a comma-separated list of bitstream filters. Use the @code{-bsfs} option
-to get the list of bitstream filters.
-@example
-avconv -i h264.mp4 -c:v copy -bsf:v h264_mp4toannexb -an out.h264
-@end example
-@example
-avconv -i file.mov -an -vn -bsf:s mov2textsub -c:s copy -f rawvideo sub.txt
-@end example
-
-@item -tag[:@var{stream_specifier}] @var{codec_tag} (@emph{output,per-stream})
-Force a tag/fourcc for matching streams.
-
-@item -cpuflags mask (@emph{global})
-Set a mask that's applied to autodetected CPU flags. This option is intended
-for testing. Do not use it unless you know what you're doing.
-
-@item -filter_complex @var{filtergraph} (@emph{global})
-Define a complex filter graph, i.e. one with arbitrary number of inputs and/or
-outputs. For simple graphs -- those with one input and one output of the same
-type -- see the @option{-filter} options. @var{filtergraph} is a description of
-the filter graph, as described in @ref{Filtergraph syntax}.
-
-Input link labels must refer to input streams using the
-@code{[file_index:stream_specifier]} syntax (i.e. the same as @option{-map}
-uses). If @var{stream_specifier} matches multiple streams, the first one will be
-used. An unlabeled input will be connected to the first unused input stream of
-the matching type.
-
-Output link labels are referred to with @option{-map}. Unlabeled outputs are
-added to the first output file.
-
-Note that with this option it is possible to use only lavfi sources without
-normal input files.
-
-For example, to overlay an image over video
-@example
-avconv -i video.mkv -i image.png -filter_complex '[0:v][1:v]overlay[out]' -map
-'[out]' out.mkv
-@end example
-Here @code{[0:v]} refers to the first video stream in the first input file,
-which is linked to the first (main) input of the overlay filter. Similarly the
-first video stream in the second input is linked to the second (overlay) input
-of overlay.
-
-Assuming there is only one video stream in each input file, we can omit input
-labels, so the above is equivalent to
-@example
-avconv -i video.mkv -i image.png -filter_complex 'overlay[out]' -map
-'[out]' out.mkv
-@end example
-
-Furthermore we can omit the output label and the single output from the filter
-graph will be added to the output file automatically, so we can simply write
-@example
-avconv -i video.mkv -i image.png -filter_complex 'overlay' out.mkv
-@end example
-
-To generate 5 seconds of pure red video using lavfi @code{color} source:
-@example
-avconv -filter_complex 'color=red' -t 5 out.mkv
-@end example
-@end table

-@chapter Tips
-@c man begin TIPS
-
-@itemize
-@item
-For streaming at very low bitrate application, use a low frame rate
-and a small GOP size. This is especially true for RealVideo where
-the Linux player does not seem to be very fast, so it can miss
-frames. An example is:
-
-@example
-avconv -g 3 -r 3 -t 10 -b 50k -s qcif -f rv10 /tmp/b.rm
-@end example
-
-@item
-The parameter 'q' which is displayed while encoding is the current
-quantizer. The value 1 indicates that a very good quality could
-be achieved. The value 31 indicates the worst quality. If q=31 appears
-too often, it means that the encoder cannot compress enough to meet
-your bitrate. You must either increase the bitrate, decrease the
-frame rate or decrease the frame size.
-
-@item
-If your computer is not fast enough, you can speed up the
-compression at the expense of the compression ratio. You can use
-'-me zero' to speed up motion estimation, and '-g 0' to disable
-motion estimation completely (you have only I-frames, which means it
-is about as good as JPEG compression).
-
-@item
-To have very low audio bitrates, reduce the sampling frequency
-(down to 22050 Hz for MPEG audio, 22050 or 11025 for AC-3).
-
-@item
-To have a constant quality (but a variable bitrate), use the option
-'-qscale n' when 'n' is between 1 (excellent quality) and 31 (worst
-quality).

-
-@chapter Examples
-@c man begin EXAMPLES
-
-@section Preset files
-
-A preset file contains a sequence of @var{option=value} pairs, one for
-each line, specifying a sequence of options which can be specified also on
-the command line. Lines starting with the hash ('#') character are ignored and
-are used to provide comments. Empty lines are also ignored. Check the
-@file{presets} directory in the Libav source tree for examples.
-
-Preset files are specified with the @code{pre} option, this option takes a
-preset name as input. Avconv searches for a file named @var{preset_name}.avpreset in
-the directories @file{$AVCONV_DATADIR} (if set), and @file{$HOME/.avconv}, and in
-the data directory defined at configuration time (usually @file{$PREFIX/share/avconv})
-in that order. For example, if the argument is @code{libx264-max}, it will
-search for the file @file{libx264-max.avpreset}.
-
-@section Video and Audio grabbing
-
-If you specify the input format and device then avconv can grab video
-and audio directly.
-
-@example
-avconv -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg
-@end example
-
-Note that you must activate the right video source and channel before
-launching avconv with any TV viewer such as
-@uref{http://linux.bytesex.org/xawtv/, xawtv} by Gerd Knorr. You also
-have to set the audio recording levels correctly with a
-standard mixer.
-
-@section X11 grabbing
-
-Grab the X11 display with avconv via
-
-@example
-avconv -f x11grab -s cif -r 25 -i :0.0 /tmp/out.mpg
-@end example
-
-0.0 is display.screen number of your X11 server, same as
-the DISPLAY environment variable.
-
-@example
-avconv -f x11grab -s cif -r 25 -i :0.0+10,20 /tmp/out.mpg
-@end example
-
-0.0 is display.screen number of your X11 server, same as the DISPLAY environment
-variable. 10 is the x-offset and 20 the y-offset for the grabbing.
-
-@section Video and Audio file format conversion
-
-Any supported file format and protocol can serve as input to avconv:
-
-Examples:
-@itemize
-@item
-You can use YUV files as input:
-
-@example
-avconv -i /tmp/test%d.Y /tmp/out.mpg
-@end example
-
-It will use the files:
-@example
-/tmp/test0.Y, /tmp/test0.U, /tmp/test0.V,
-/tmp/test1.Y, /tmp/test1.U, /tmp/test1.V, etc...
-@end example
-
-The Y files use twice the resolution of the U and V files. They are
-raw files, without header. They can be generated by all decent video
-decoders. You must specify the size of the image with the @option{-s} option
-if avconv cannot guess it.
-
-@item
-You can input from a raw YUV420P file:
-
-@example
-avconv -i /tmp/test.yuv /tmp/out.avi
-@end example
-
-test.yuv is a file containing raw YUV planar data. Each frame is composed
-of the Y plane followed by the U and V planes at half vertical and
-horizontal resolution.
-
-@item
-You can output to a raw YUV420P file:
-
-@example
-avconv -i mydivx.avi hugefile.yuv
-@end example
-
-@item
-You can set several input files and output files:
-
-@example
-avconv -i /tmp/a.wav -s 640x480 -i /tmp/a.yuv /tmp/a.mpg
-@end example
-
-Converts the audio file a.wav and the raw YUV video file a.yuv
-to MPEG file a.mpg.
-
-@item
-You can also do audio and video conversions at the same time:
-
-@example
-avconv -i /tmp/a.wav -ar 22050 /tmp/a.mp2
-@end example
-
-Converts a.wav to MPEG audio at 22050 Hz sample rate.
-
-@item
-You can encode to several formats at the same time and define a
-mapping from input stream to output streams:
-
-@example
-avconv -i /tmp/a.wav -map 0:a -b 64k /tmp/a.mp2 -map 0:a -b 128k /tmp/b.mp2
-@end example
-
-Converts a.wav to a.mp2 at 64 kbits and to b.mp2 at 128 kbits. '-map
-file:index' specifies which input stream is used for each output
-stream, in the order of the definition of output streams.
-
-@item
-You can transcode decrypted VOBs:
-
-@example
-avconv -i snatch_1.vob -f avi -c:v mpeg4 -b:v 800k -g 300 -bf 2 -c:a libmp3lame -b:a 128k snatch.avi
-@end example
-
-This is a typical DVD ripping example; the input is a VOB file, the
-output an AVI file with MPEG-4 video and MP3 audio. Note that in this
-command we use B-frames so the MPEG-4 stream is DivX5 compatible, and
-GOP size is 300 which means one intra frame every 10 seconds for 29.97fps
-input video. Furthermore, the audio stream is MP3-encoded so you need
-to enable LAME support by passing @code{--enable-libmp3lame} to configure.
-The mapping is particularly useful for DVD transcoding
-to get the desired audio language.
-
-NOTE: To see the supported input formats, use @code{avconv -formats}.
-
-@item
-You can extract images from a video, or create a video from many images:
-
-For extracting images from a video:
-@example
-avconv -i foo.avi -r 1 -s WxH -f image2 foo-%03d.jpeg
-@end example
-
-This will extract one video frame per second from the video and will
-output them in files named @file{foo-001.jpeg}, @file{foo-002.jpeg},
-etc. Images will be rescaled to fit the new WxH values.
-
-If you want to extract just a limited number of frames, you can use the

-
-@item
-You can put many streams of the same type in the output:
-
-@example
-avconv -i test1.avi -i test2.avi -map 0.3 -map 0.2 -map 0.1 -map 0.0 -c copy test12.nut
-@end example
-
-The resulting output file @file{test12.avi} will contain first four streams from

-To force CBR video output:
-@example
-avconv -i myfile.avi -b 4000k -minrate 4000k -maxrate 4000k -bufsize 1835k out.m2v
-@end example
-
-@item
-The four options lmin, lmax, mblmin and mblmax use 'lambda' units,

-@chapter Description
-@c man begin DESCRIPTION
-
-avprobe gathers information from multimedia streams and prints it in
-human- and machine-readable fashion.
-
-For example it can be used to check the format of the container used
-by a multimedia stream and the format and type of each media stream
-contained in it.
-
-If a filename is specified in input, avprobe will try to open and
-probe the file content. If the file cannot be opened or recognized as
-a multimedia file, a positive exit code is returned.
-
-avprobe may be employed both as a standalone application or in
-combination with a textual filter, which may perform more
-sophisticated processing, e.g. statistical processing or plotting.
-
-Options are used to list some of the formats supported by avprobe or
-for specifying which information to display, and for setting how
-avprobe will show it.
-
-avprobe output is designed to be easily parsable by any INI or JSON
-parsers.

-@c man end

-
-@chapter Description
-@c man begin DESCRIPTION
-
-WARNING: avserver is unmaintained, largely broken and in need of a
-complete rewrite. It probably won't work for you. Use at your own
-risk.
-
-avserver is a streaming server for both audio and video. It supports
-several live feeds, streaming from files and time shifting on live feeds
-(you can seek to positions in the past on each live feed, provided you
-specify a big enough feed storage in avserver.conf).
-
-avserver runs in daemon mode by default; that is, it puts itself in
-the background and detaches from its TTY, unless it is launched in
-debug mode or a NoDaemon option is specified in the configuration
-file.
-
-This documentation covers only the streaming aspects of avserver /
-avconv. All questions about parameters for avconv, codec questions,
-etc. are not covered here. Read @file{avconv.html} for more
-information.
-
-@section How does it work?
-
-avserver receives prerecorded files or FFM streams from some avconv
-instance as input, then streams them over RTP/RTSP/HTTP.
-
-An avserver instance will listen on some port as specified in the
-configuration file. You can launch one or more instances of avconv and
-send one or more FFM streams to the port where avserver is expecting
-to receive them. Alternately, you can make avserver launch such avconv
-instances at startup.
-
-Input streams are called feeds, and each one is specified by a <Feed>
-section in the configuration file.
-
-For each feed you can have different output streams in various
-formats, each one specified by a <Stream> section in the configuration
-file.
-
-@section Status stream
-
-avserver supports an HTTP interface which exposes the current status
-of the server.
-
-Simply point your browser to the address of the special status stream
-specified in the configuration file.
-
-For example if you have:
-@example
-<Stream status.html>
-Format status
-
-# Only allow local people to get the status
-ACL allow localhost
-ACL allow 192.168.0.0 192.168.255.255
-</Stream>
-@end example

-then the server will post a page with the status information when
-the special stream @file{status.html} is requested.
-
-@section What can this do?
-
-When properly configured and running, you can capture video and audio in real
-time from a suitable capture card, and stream it out over the Internet to
-either Windows Media Player or RealAudio player (with some restrictions).
-
-It can also stream from files, though that is currently broken. Very often, a
-web server can be used to serve up the files just as well.
-
-It can stream prerecorded video from .ffm files, though it is somewhat tricky
-to make it work correctly.
-
-@section What do I need?
-
-I use Linux on a 900 MHz Duron with a cheapo Bt848 based TV capture card. I'm
-using stock Linux 2.4.17 with the stock drivers. [Actually that isn't true,
-I needed some special drivers for my motherboard-based sound card.]
-
-I understand that FreeBSD systems work just fine as well.
-
-@section How do I make it work?
-
-First, build the kit. It *really* helps to have installed LAME first. Then when
-you run the avserver ./configure, make sure that you have the
-@code{--enable-libmp3lame} flag turned on.
-
-LAME is important as it allows for streaming audio to Windows Media Player.
-Don't ask why the other audio types do not work.
-
-As a simple test, just run the following two command lines where INPUTFILE
-is some file which you can decode with avconv:
-
-@example
-./avserver -f doc/avserver.conf &
-./avconv -i INPUTFILE http://localhost:8090/feed1.ffm
-@end example
-
-At this point you should be able to go to your Windows machine and fire up
-Windows Media Player (WMP). Go to Open URL and enter
-
-@example
- http://<linuxbox>:8090/test.asf
-@end example
-
-You should (after a short delay) see video and hear audio.
-
-WARNING: trying to stream test1.mpg doesn't work with WMP as it tries to
-transfer the entire file before starting to play.
-The same is true of AVI files.
-
-@section What happens next?
-
-You should edit the avserver.conf file to suit your needs (in terms of
-frame rates etc). Then install avserver and avconv, write a script to start
-them up, and off you go.
-
-@section Troubleshooting
-
-@subsection I don't hear any audio, but video is fine.
-
-Maybe you didn't install LAME, or got your ./configure statement wrong. Check
-the avconv output to see if a line referring to MP3 is present. If not, then
-your configuration was incorrect. If it is, then maybe your wiring is not
-set up correctly. Maybe the sound card is not getting data from the right
-input source. Maybe you have a really awful audio interface (like I do)
-that only captures in stereo and also requires that one channel be flipped.
-If you are one of these people, then export 'AUDIO_FLIP_LEFT=1' before
-starting avconv.
-
-@subsection The audio and video lose sync after a while.
-
-Yes, they do.
-
-@subsection After a long while, the video update rate goes way down in WMP.
-
-Yes, it does. Who knows why?
-
-@subsection WMP 6.4 behaves differently to WMP 7.
-
-Yes, it does. Any thoughts on this would be gratefully received. These
-differences extend to embedding WMP into a web page. [There are two
-object IDs that you can use: The old one, which does not play well, and
-the new one, which does (both tested on the same system). However,
-I suspect that the new one is not available unless you have installed WMP 7].
-
-@section What else can it do?
-
-You can replay video from .ffm files that was recorded earlier.
-However, there are a number of caveats, including the fact that the
-avserver parameters must match the original parameters used to record the
-file. If they do not, then avserver deletes the file before recording into it.
-(Now that I write this, it seems broken).
-
-You can fiddle with many of the codec choices and encoding parameters, and
-there are a bunch more parameters that you cannot control. Post a message
-to the mailing list if there are some 'must have' parameters. Look in
-avserver.conf for a list of the currently available controls.
-
-It will automatically generate the ASX or RAM files that are often used
-in browsers. These files are actually redirections to the underlying ASF
-or RM file. The reason for this is that the browser often fetches the
-entire file before starting up the external viewer. The redirection files
-are very small and can be transferred quickly. [The stream itself is
-often 'infinite' and thus the browser tries to download it and never
-finishes.]
-
-@section Tips
-
-* When you connect to a live stream, most players (WMP, RA, etc) want to
-buffer a certain number of seconds of material so that they can display the
-signal continuously. However, avserver (by default) starts sending data
-in realtime. This means that there is a pause of a few seconds while the
-buffering is being done by the player. The good news is that this can be
-cured by adding a '?buffer=5' to the end of the URL. This means that the
-stream should start 5 seconds in the past -- and so the first 5 seconds
-of the stream are sent as fast as the network will allow. It will then
-slow down to real time. This noticeably improves the startup experience.
-
-You can also add a 'Preroll 15' statement into the avserver.conf that will
-add the 15 second prebuffering on all requests that do not otherwise
-specify a time. In addition, avserver will skip frames until a key_frame
-is found. This further reduces the startup delay by not transferring data
-that will be discarded.
-
-* You may want to adjust the MaxBandwidth in the avserver.conf to limit
-the amount of bandwidth consumed by live streams.
-
-@section Why does the ?buffer / Preroll stop working after a time?
-
-It turns out that (on my machine at least) the number of frames successfully
-grabbed is marginally less than the number that ought to be grabbed. This
-means that the timestamp in the encoded data stream gets behind realtime.
-This means that if you say 'Preroll 10', then when the stream gets 10
-or more seconds behind, there is no Preroll left.
-
-Fixing this requires a change in the internals of how timestamps are
-handled.
-
-@section Does the @code{?date=} stuff work.
-
-Yes (subject to the limitation outlined above). Also note that whenever you
-start avserver, it deletes the ffm file (if any parameters have changed),
-thus wiping out what you had recorded before.
-
-The format of the @code{?date=xxxxxx} is fairly flexible. You should use one
-of the following formats (the 'T' is literal):
-
-@example
-* YYYY-MM-DDTHH:MM:SS (localtime)
-* YYYY-MM-DDTHH:MM:SSZ (UTC)
-@end example
-
-You can omit the YYYY-MM-DD, and then it refers to the current day. However
-note that @samp{?date=16:00:00} refers to 16:00 on the current day -- this
-may be in the future and so is unlikely to be useful.
-
-You use this by adding the ?date= to the end of the URL for the stream.
-For example: @samp{http://localhost:8080/test.asf?date=2002-07-26T23:05:00}.

-The code is written in K&R C style. That means the following:
-@itemize @bullet

-The control statements are formatted by putting space between the statement
-and parenthesis in the following way:
-@example
-for (i = 0; i < filter->input_count; i++) @{

- continue;
-case AVLINK_STARTINIT:
- av_log(filter, AV_LOG_INFO, "circular filter chain detected");
- return 0;

@section How can I join video files?
-A few multimedia containers (MPEG-1, MPEG-2 PS, DV) allow to join video files by
-merely concatenating them.
+To "join" video files is quite ambiguous. The following list explains the
+different kinds of "joining" and points out how those are addressed in
+FFmpeg. To join video files may mean:
+
+@itemize
+
+@item
+To put them one after the other: this is called to @emph{concatenate} them
+(in short: concat) and is addressed
+@ref{How can I concatenate video files, in this very faq}.
+
+@item
+To put them together in the same file, to let the user choose between the
+different versions (example: different audio languages): this is called to
+@emph{multiplex} them together (in short: mux), and is done by simply
+invoking ffmpeg with several @option{-i} options.
+
+@item
+For audio, to put all channels together in a single stream (example: two
+mono streams into one stereo stream): this is sometimes called to
+@emph{merge} them, and can be done using the
+@url{http://ffmpeg.org/ffmpeg.html#amerge, @code{amerge}} filter.
+
+@item
+For audio, to play one on top of the other: this is called to @emph{mix}
+them, and can be done by first merging them into a single stream and then
+using the @url{http://ffmpeg.org/ffmpeg.html#pan, @code{pan}} filter to mix
+the channels at will.
+
+@item
+For video, to display both together, side by side or one on top of a part of
+the other; it can be done using the
+@url{http://ffmpeg.org/ffmpeg.html#overlay, @code{overlay}} video filter.
+
+@end itemize
+
+@anchor{How can I concatenate video files}
+@section How can I concatenate video files?
+
+There are several solutions, depending on the exact circumstances.
+
+@subsection Concatenating using filters
+
+FFmpeg has a @url{http://ffmpeg.org/ffmpeg.html#concat-1, @code{concat}}
+filter designed specifically for that, with examples in the documentation.
+
+@subsection Concatenating at the file level
+
+A few multimedia containers (MPEG-1, MPEG-2 PS, DV) allow to concatenate
+video by merely concatenating the files them.

+
+VOB and a few other formats do not have a global header that describes

+the beginning is scanned. If the subtitles happen only later in the file,
+they will not be initally detected.
+
+Some applications, including the @code{ffmpeg} command-line tool, can only
+work with streams that were detected during the initial scan; streams that
+are detected later are ignored.
+
+The size of the initial scan is controlled by two options: @code{probesize}
+(default ~5 Mo) and @code{analyzeduration} (default 5,000,000 µs = 5 s). For
+the subtitle stream to be detected, both values must be large enough.

@chapter Introduction
-FATE provides a regression testsuite embedded within the Libav build system.
-It can be run locally and optionally configured to send reports to a web
-aggregator and viewer @url{http://fate.libav.org}.
+ FATE is an extended regression suite on the client-side and a means
+for results aggregation and presentation on the server-side.
-It is advised to run FATE before submitting patches to the current codebase
-and provide new tests when submitting patches to add additional features.
+ The first part of this document explains how you can use FATE from
+your FFmpeg source directory to test your ffmpeg binary. The second
+part describes how you can run FATE to submit the results to FFmpeg's
+FATE server.
-@chapter Running FATE
+ In any way you can have a look at the publicly viewable FATE results
+by visiting this website:
-@section Samples and References
-In order to run, FATE needs a large amount of data (samples and references)
-that is provided separately from the actual source distribution.
+ @url{http://fate.ffmpeg.org/}
-To inform the build system about the testsuite location, pass
-@option{--samples=<path to the samples>} to @command{configure} or set the
-@var{SAMPLES} Make variable or the @var{LIBAV_SAMPLES} environment variable
-to a suitable value.
+ This is especially recommended for all people contributing source
+code to FFmpeg, as it can be seen if some test on some platform broke
+with there recent contribution. This usually happens on the platforms
+the developers could not test on.
+
+ The second part of this document describes how you can run FATE to
+submit your results to FFmpeg's FATE server. If you want to submit your
+results be sure to check that your combination of CPU, OS and compiler
+is not already listed on the above mentioned website.
+
+ In the third part you can find a comprehensive listing of FATE makefile
+targets and variables.
+
+
+@chapter Using FATE from your FFmpeg source directory
+
+ If you want to run FATE on your machine you need to have the samples
+in place. You can get the samples via the build target fate-rsync.
+Use this command from the top-level source directory:
+
+@example
+make fate-rsync SAMPLES=fate-suite/
+make fate SAMPLES=fate-suite/
+@end example
+
+ The above commands set the samples location by passing a makefile
+variable via command line. It is also possible to set the samples
+location at source configuration time by invoking configure with
+`--samples=<path to the samples directory>'. Afterwards you can
+invoke the makefile targets without setting the SAMPLES makefile
+variable. This is illustrated by the following commands:
+
+@example
+./configure --samples=fate-suite/
+make fate-rsync
+make fate
+@end example
+
+ Yet another way to tell FATE about the location of the sample
+directory is by making sure the environment variable FATE_SAMPLES
+contains the path to your samples directory. This can be achieved
+by e.g. putting that variable in your shell profile or by setting
+it in your interactive session.
+
+@example
+FATE_SAMPLES=fate-suite/ make fate
+@end example
+
+@float NOTE
+Do not put a '~' character in the samples path to indicate a home
+directory. Because of shell nuances, this will cause FATE to fail.
+@end float
To use a custom wrapper to run the test, pass @option{--target-exec} to
@command{configure} or set the @var{TARGET_EXEC} Make variable.
-The dataset is available through @command{rsync}, is possible to fetch
-the current sample using the straight rsync command or through a specific
-@ref{Makefile target}.
+
+@chapter Submitting the results to the FFmpeg result aggregation server
+
+ To submit your results to the server you should run fate through the
+shell script @file{tests/fate.sh} from the FFmpeg sources. This script needs
+to be invoked with a configuration file as its first argument.
@example
-# rsync -aL rsync://fate-suite.libav.org/fate-suite/ fate-suite
+tests/fate.sh /path/to/fate_config
@end example
-@example
-# make fate-rsync SAMPLES=fate-suite
-@end example
+ A configuration file template with comments describing the individual
+configuration variables can be found at @file{doc/fate_config.sh.template}.
+
+@ifhtml
+ The mentioned configuration template is also available here:
+@verbatiminclude fate_config.sh.template
+@end ifhtml
+
+ Create a configuration that suits your needs, based on the configuration
+template. The `slot' configuration variable can be any string that is not
+yet used, but it is suggested that you name it adhering to the following
+pattern <arch>-<os>-<compiler>-<compiler version>. The configuration file
+itself will be sourced in a shell script, therefore all shell features may
+be used. This enables you to setup the environment as you need it for your
+build.
+
+ For your first test runs the `fate_recv' variable should be empty or
+commented out. This will run everything as normal except that it will omit
+the submission of the results to the server. The following files should be
+present in $workdir as specified in the configuration file:
+
+@itemize
+ @item configure.log
+ @item compile.log
+ @item test.log
+ @item report
+ @item version
+@end itemize
+
+ When you have everything working properly you can create an SSH key pair
+and send the public key to the FATE server administrator who can be contacted
+at the email address @email{fate-admin@@ffmpeg.org}.
+
+ Configure your SSH client to use public key authentication with that key
+when connecting to the FATE server. Also do not forget to check the identity
+of the server and to accept its host key. This can usually be achieved by
+running your SSH client manually and killing it after you accepted the key.
+The FATE server's fingerprint is:
+
+ b1:31:c8:79:3f:04:1d:f8:f2:23:26:5a:fd:55:fa:92
+
+ If you have problems connecting to the FATE server, it may help to try out
+the @command{ssh} command with one or more @option{-v} options. You should
+get detailed output concerning your SSH configuration and the authentication
+process.
+
+ The only thing left is to automate the execution of the fate.sh script and
+the synchronisation of the samples directory.

+
+The generic syntax is:
+
+@example
+@c man begin SYNOPSIS
+ffmpeg [global options] [[infile options][@option{-i} @var{infile}]]... @{[outfile options] @var{outfile}@}...
+@c man end
+@end example
+
+@chapter Description
+@c man begin DESCRIPTION
+
+ffmpeg is a very fast video and audio converter that can also grab from
+a live audio/video source. It can also convert between arbitrary sample
+rates and resize video on the fly with a high quality polyphase filter.
+
+ffmpeg reads from an arbitrary number of input "files" (which can be regular
+files, pipes, network streams, grabbing devices, etc.), specified by the
+@code{-i} option, and writes to an arbitrary number of output "files", which are
+specified by a plain output filename. Anything found on the command line which
+cannot be interpreted as an option is considered to be an output filename.
+
+Each input or output file can in principle contain any number of streams of
+different types (video/audio/subtitle/attachment/data). Allowed number and/or
+types of streams can be limited by the container format. Selecting, which
+streams from which inputs go into output, is done either automatically or with
+the @code{-map} option (see the Stream selection chapter).
+
+To refer to input files in options, you must use their indices (0-based). E.g.
+the first input file is @code{0}, the second is @code{1} etc. Similarly, streams
+within a file are referred to by their indices. E.g. @code{2:3} refers to the
+fourth stream in the third input file. See also the Stream specifiers chapter.
+
+As a general rule, options are applied to the next specified
+file. Therefore, order is important, and you can have the same
+option on the command line multiple times. Each occurrence is
+then applied to the next input or output file.
+Exceptions from this rule are the global options (e.g. verbosity level),
+which should be specified first.
+
+Do not mix input and output files -- first specify all input files, then all
+output files. Also do not mix options which belong to different files. All
+options apply ONLY to the next input or output file and are reset between files.
+
+@itemize
+@item
+To set the video bitrate of the output file to 64kbit/s:
+@example
+ffmpeg -i input.avi -b:v 64k output.avi

+
+@chapter Detailed description
+@c man begin DETAILED DESCRIPTION
+
+The transcoding process in @command{ffmpeg} for each output can be described by
+the following diagram:
+
+@example
+ _______ ______________ _________ ______________ ________
+| | | | | | | | | |
+| input | demuxer | encoded data | decoder | decoded | encoder | encoded data | muxer | output |
+| file | ---------> | packets | ---------> | frames | ---------> | packets | -------> | file |
+|_______| |______________| |_________| |______________| |________|
+
+@end example
+
+@command{ffmpeg} calls the libavformat library (containing demuxers) to read
+input files and get packets containing encoded data from them. When there are
+multiple input files, @command{ffmpeg} tries to keep them synchronized by
+tracking lowest timestamp on any active input stream.
+
+Encoded packets are then passed to the decoder (unless streamcopy is selected
+for the stream, see further for a description). The decoder produces
+uncompressed frames (raw video/PCM audio/...) which can be processed further by
+filtering (see next section). After filtering the frames are passed to the
+encoder, which encodes them and outputs encoded packets again. Finally those are
+passed to the muxer, which writes the encoded packets to the output file.
+
+@section Filtering
+Before encoding, @command{ffmpeg} can process raw audio and video frames using
+filters from the libavfilter library. Several chained filters form a filter
+graph. @command{ffmpeg} distinguishes between two types of filtergraphs -
+simple and complex.
+
+@subsection Simple filtergraphs
+Simple filtergraphs are those that have exactly one input and output, both of
+the same type. In the above diagram they can be represented by simply inserting
+an additional step between decoding and encoding:
+
+@example
+ _________ __________ ______________
+| | | | | |
+| decoded | simple filtergraph | filtered | encoder | encoded data |
+| frames | -------------------> | frames | ---------> | packets |
+|_________| |__________| |______________|
+
+@end example
+
+Simple filtergraphs are configured with the per-stream @option{-filter} option
+(with @option{-vf} and @option{-af} aliases for video and audio respectively).
+A simple filtergraph for video can look for example like this:
+
+@example
+ _______ _____________ _______ _____ ________
+| | | | | | | | | |
+| input | ---> | deinterlace | ---> | scale | ---> | fps | ---> | output |
+|_______| |_____________| |_______| |_____| |________|
+
+@end example
+
+Note that some filters change frame properties but not frame contents. E.g. the
+@code{fps} filter in the example above changes number of frames, but does not
+touch the frame contents. Another example is the @code{setpts} filter, which
+only sets timestamps and otherwise passes the frames unchanged.
+
+@subsection Complex filtergraphs
+Complex filtergraphs are those which cannot be described as simply a linear
+processing chain applied to one stream. This is the case e.g. when the graph has
+more than one input and/or output, or when output stream type is different from
+input. They can be represented with the following diagram:
+
+@example
+ _________
+| |
+| input 0 |\ __________
+|_________| \ | |
+ \ _________ /| output 0 |
+ \ | | / |__________|
+ _________ \| complex | /
+| | | |/
+| input 1 |---->| filter |\
+|_________| | | \ __________
+ /| graph | \ | |
+ / | | \| output 1 |
+ _________ / |_________| |__________|
+| | /
+| input 2 |/
+|_________|
+
+@end example
+
+Complex filtergraphs are configured with the @option{-filter_complex} option.
+Note that this option is global, since a complex filtergraph by its nature
+cannot be unambiguously associated with a single stream or file.
+
+A trivial example of a complex filtergraph is the @code{overlay} filter, which
+has two video inputs and one video output, containing one video overlaid on top
+of the other. Its audio counterpart is the @code{amix} filter.
+
+@section Stream copy
+Stream copy is a mode selected by supplying the @code{copy} parameter to the
+@option{-codec} option. It makes @command{ffmpeg} omit the decoding and encoding
+step for the specified stream, so it does only demuxing and muxing. It is useful
+for changing the container format or modifying container-level metadata. The
+diagram above will in this case simplify to this:
+
+@example
+ _______ ______________ ________
+| | | | | |
+| input | demuxer | encoded data | muxer | output |
+| file | ---------> | packets | -------> | file |
+|_______| |______________| |________|
+
+@end example
+
+Since there is no decoding or encoding, it is very fast and there is no quality
+loss. However it might not work in some cases because of many factors. Applying
+filters is obviously also impossible, since filters work on uncompressed data.
+
+@c man end DETAILED DESCRIPTION
+
+@chapter Stream selection
+@c man begin STREAM SELECTION
+
+By default ffmpeg includes only one stream of each type (video, audio, subtitle)
+present in the input files and adds them to each output file. It picks the
+"best" of each based upon the following criteria; for video it is the stream
+with the highest resolution, for audio the stream with the most channels, for
+subtitle it's the first subtitle stream. In the case where several streams of
+the same type rate equally, the lowest numbered stream is chosen.
+
+You can disable some of those defaults by using @code{-vn/-an/-sn} options. For
+full manual control, use the @code{-map} option, which disables the defaults just
+described.
+
+@c man end STREAM SELECTION
+
+@chapter Options
+@c man begin OPTIONS
+
+@include avtools-common-opts.texi
+
+@section Main options
+
+@table @option
+
+@item -f @var{fmt} (@emph{input/output})
+Force input or output file format. The format is normally auto detected for input
+files and guessed from file extension for output files, so this option is not
+needed in most cases.
+
+@item -i @var{filename} (@emph{input})
+input file name
+
+@item -y (@emph{global})
+Overwrite output files without asking.
+
+@item -n (@emph{global})
+Do not overwrite output files but exit if file exists.
+
+@item -c[:@var{stream_specifier}] @var{codec} (@emph{input/output,per-stream})
+@itemx -codec[:@var{stream_specifier}] @var{codec} (@emph{input/output,per-stream})
+Select an encoder (when used before an output file) or a decoder (when used
+before an input file) for one or more streams. @var{codec} is the name of a
+decoder/encoder or a special value @code{copy} (output only) to indicate that
+the stream is not to be re-encoded.
+
+For example
+@example
+ffmpeg -i INPUT -map 0 -c:v libx264 -c:a copy OUTPUT
+@end example
+encodes all video streams with libx264 and copies all audio streams.
+
+For each stream, the last matching @code{c} option is applied, so
+@example
+ffmpeg -i INPUT -map 0 -c copy -c:v:1 libx264 -c:a:137 libvorbis OUTPUT
+@end example
+will copy all the streams except the second video, which will be encoded with
+libx264, and the 138th audio, which will be encoded with libvorbis.
+
+@item -t @var{duration} (@emph{output})
+Stop writing the output after its duration reaches @var{duration}.
+@var{duration} may be a number in seconds, or in @code{hh:mm:ss[.xxx]} form.
+
+@item -fs @var{limit_size} (@emph{output})
+Set the file size limit, expressed in bytes.
+
+@item -ss @var{position} (@emph{input/output})
+When used as an input option (before @code{-i}), seeks in this input file to
+@var{position}. When used as an output option (before an output filename),
+decodes but discards input until the timestamps reach @var{position}. This is
+slower, but more accurate.
+
+@var{position} may be either in seconds or in @code{hh:mm:ss[.xxx]} form.
+
+@item -itsoffset @var{offset} (@emph{input})
+Set the input time offset in seconds.
+@code{[-]hh:mm:ss[.xxx]} syntax is also supported.
+The offset is added to the timestamps of the input files.
+Specifying a positive offset means that the corresponding
+streams are delayed by @var{offset} seconds.
+
+@item -timestamp @var{time} (@emph{output})
+Set the recording timestamp in the container.
+The syntax for @var{time} is:
+@example
+now|([(YYYY-MM-DD|YYYYMMDD)[T|t| ]]((HH:MM:SS[.m...])|(HHMMSS[.m...]))[Z|z])
+@end example
+If the value is "now" it takes the current time.
+Time is local time unless 'Z' or 'z' is appended, in which case it is
+interpreted as UTC.
+If the year-month-day part is not specified it takes the current
+year-month-day.
+
+@item -metadata[:metadata_specifier] @var{key}=@var{value} (@emph{output,per-metadata})
+Set a metadata key/value pair.
+
+An optional @var{metadata_specifier} may be given to set metadata
+on streams or chapters. See @code{-map_metadata} documentation for
+details.
+
+This option overrides metadata set with @code{-map_metadata}. It is
+also possible to delete metadata by using an empty value.
+
+For example, for setting the title in the output file:
+@example
+ffmpeg -i in.avi -metadata title="my title" out.flv
+@end example
+
+To set the language of the first audio stream:
+@example
+ffmpeg -i INPUT -metadata:s:a:1 language=eng OUTPUT
+@end example
+
+@item -target @var{type} (@emph{output})
+Specify target file type (@code{vcd}, @code{svcd}, @code{dvd}, @code{dv},
+@code{dv50}). @var{type} may be prefixed with @code{pal-}, @code{ntsc-} or
+@code{film-} to use the corresponding standard. All the format options
+(bitrate, codecs, buffer sizes) are then set automatically. You can just type:
+
+@example
+ffmpeg -i myfile.avi -target vcd /tmp/vcd.mpg
+@end example
+
+Nevertheless you can specify additional options as long as you know
+they do not conflict with the standard, as in:
+
+@example
+ffmpeg -i myfile.avi -target vcd -bf 2 /tmp/vcd.mpg
+@end example
+
+@item -dframes @var{number} (@emph{output})
+Set the number of data frames to record. This is an alias for @code{-frames:d}.
+
+@item -frames[:@var{stream_specifier}] @var{framecount} (@emph{output,per-stream})
+Stop writing to the stream after @var{framecount} frames.
+
+@item -q[:@var{stream_specifier}] @var{q} (@emph{output,per-stream})
+@itemx -qscale[:@var{stream_specifier}] @var{q} (@emph{output,per-stream})
+Use fixed quality scale (VBR). The meaning of @var{q} is
+codec-dependent.
+
+@item -filter[:@var{stream_specifier}] @var{filter_graph} (@emph{output,per-stream})
+@var{filter_graph} is a description of the filter graph to apply to
+the stream. Use @code{-filters} to show all the available filters
+(including also sources and sinks).
+
+See also the @option{-filter_complex} option if you want to create filter graphs
+with multiple inputs and/or outputs.
+@item -pre[:@var{stream_specifier}] @var{preset_name} (@emph{output,per-stream})
+Specify the preset for matching stream(s).
+
+@item -stats (@emph{global})
+Print encoding progress/statistics. On by default.
+
+@item -progress @var{url} (@emph{global})
+Send program-friendly progress information to @var{url}.
+
+Progress information is written approximately every second and at the end of
+the encoding process. It is made of "@var{key}=@var{value}" lines. @var{key}
+consists of only alphanumeric characters. The last key of a sequence of
+progress information is always "progress".
+
+@item -stdin
+Enable interaction on standard input. On by default unless standard input is
+used as an input. To explicitly disable interaction you need to specify
+@code{-nostdin}.
+
+Disabling interaction on standard input is useful, for example, if
+ffmpeg is in the background process group. Roughly the same result can
+be achieved with @code{ffmpeg ... < /dev/null} but it requires a
+shell.
+
+@item -debug_ts (@emph{global})
+Print timestamp information. It is off by default. This option is
+mostly useful for testing and debugging purposes, and the output
+format may change from one version to another, so it should not be
+employed by portable scripts.
+
+See also the option @code{-fdebug ts}.
+
+@item -attach @var{filename} (@emph{output})
+Add an attachment to the output file. This is supported by a few formats
+like Matroska for e.g. fonts used in rendering subtitles. Attachments
+are implemented as a specific type of stream, so this option will add
+a new stream to the file. It is then possible to use per-stream options
+on this stream in the usual way. Attachment streams created with this
+option will be created after all the other streams (i.e. those created
+with @code{-map} or automatic mappings).
+
+Note that for Matroska you also have to set the mimetype metadata tag:
+@example
+ffmpeg -i INPUT -attach DejaVuSans.ttf -metadata:s:2 mimetype=application/x-truetype-font out.mkv
+@end example
+(assuming that the attachment stream will be third in the output file).
+
+@item -dump_attachment[:@var{stream_specifier}] @var{filename} (@emph{input,per-stream})
+Extract the matching attachment stream into a file named @var{filename}. If
+@var{filename} is empty, then the value of the @code{filename} metadata tag
+will be used.
+
+E.g. to extract the first attachment to a file named 'out.ttf':
+@example
+ffmpeg -dump_attachment:t:0 out.ttf INPUT
+@end example
+To extract all attachments to files determined by the @code{filename} tag:
+@example
+ffmpeg -dump_attachment:t "" INPUT
+@end example
+
+Technical note -- attachments are implemented as codec extradata, so this
+option can actually be used to extract extradata from any stream, not just
+attachments.
+
+@end table
+
+@section Video Options
+
+@table @option
+@item -vframes @var{number} (@emph{output})
+Set the number of video frames to record. This is an alias for @code{-frames:v}.
+@item -r[:@var{stream_specifier}] @var{fps} (@emph{input/output,per-stream})
+Set frame rate (Hz value, fraction or abbreviation).
+
+As an input option, ignore any timestamps stored in the file and instead
+generate timestamps assuming constant frame rate @var{fps}.
+
+As an output option, duplicate or drop input frames to achieve constant output
+frame rate @var{fps} (note that this actually causes the @code{fps} filter to be
+inserted to the end of the corresponding filtergraph).
+
+@item -s[:@var{stream_specifier}] @var{size} (@emph{input/output,per-stream})
+Set frame size.
+
+As an input option, this is a shortcut for the @option{video_size} private
+option, recognized by some demuxers for which the frame size is either not
+stored in the file or is configurable -- e.g. raw video or video grabbers.
+
+As an output option, this inserts the @code{scale} video filter to the
+@emph{end} of the corresponding filtergraph. Please use the @code{scale} filter
+directly to insert it at the beginning or some other place.
+
+The format is @samp{wxh} (default - same as source).
+
+@item -aspect[:@var{stream_specifier}] @var{aspect} (@emph{output,per-stream})
+Set the video display aspect ratio specified by @var{aspect}.
+
+@var{aspect} can be a floating point number string, or a string of the
+form @var{num}:@var{den}, where @var{num} and @var{den} are the
+numerator and denominator of the aspect ratio. For example "4:3",
+"16:9", "1.3333", and "1.7777" are valid argument values.
+
+@item -croptop @var{size}
+@item -cropbottom @var{size}
+@item -cropleft @var{size}
+@item -cropright @var{size}
+All the crop options have been removed. Use -vf
+crop=width:height:x:y instead.
+
+@item -padtop @var{size}
+@item -padbottom @var{size}
+@item -padleft @var{size}
+@item -padright @var{size}
+@item -padcolor @var{hex_color}
+All the pad options have been removed. Use -vf
+pad=width:height:x:y:color instead.
+
+@item -vn (@emph{output})
+Disable video recording.
+
+@item -vcodec @var{codec} (@emph{output})
+Set the video codec. This is an alias for @code{-codec:v}.
+
+@item -pass[:@var{stream_specifier}] @var{n} (@emph{output,per-stream})
+Select the pass number (1 or 2). It is used to do two-pass
+video encoding. The statistics of the video are recorded in the first
+pass into a log file (see also the option -passlogfile),
+and in the second pass that log file is used to generate the video
+at the exact requested bitrate.
+On pass 1, you may just deactivate audio and set output to null,
+examples for Windows and Unix:
+@example
+ffmpeg -i foo.mov -c:v libxvid -pass 1 -an -f rawvideo -y NUL
+ffmpeg -i foo.mov -c:v libxvid -pass 1 -an -f rawvideo -y /dev/null
+@end example
+
+@item -passlogfile[:@var{stream_specifier}] @var{prefix} (@emph{output,per-stream})
+Set two-pass log file name prefix to @var{prefix}, the default file name
+prefix is ``ffmpeg2pass''. The complete file name will be
+@file{PREFIX-N.log}, where N is a number specific to the output
+stream
+
+@item -vlang @var{code}
+Set the ISO 639 language code (3 letters) of the current video stream.
+
+@item -vf @var{filter_graph} (@emph{output})
+@var{filter_graph} is a description of the filter graph to apply to
+the input video.
+Use the option "-filters" to show all the available filters (including
+also sources and sinks). This is an alias for @code{-filter:v}.
+
+@end table
+
+@section Advanced Video Options
+
+@table @option
+@item -pix_fmt[:@var{stream_specifier}] @var{format} (@emph{input/output,per-stream})
+Set pixel format. Use @code{-pix_fmts} to show all the supported
+pixel formats.
+If the selected pixel format can not be selected, ffmpeg will print a
+warning and select the best pixel format supported by the encoder.
+If @var{pix_fmt} is prefixed by a @code{+}, ffmpeg will exit with an error
+if the requested pixel format can not be selected, and automatic conversions
+inside filter graphs are disabled.
+If @var{pix_fmt} is a single @code{+}, ffmpeg selects the same pixel format
+as the input (or graph output) and automatic conversions are disabled.
+
+@item -sws_flags @var{flags} (@emph{input/output})
+Set SwScaler flags.
+@item -vdt @var{n}
+Discard threshold.
+
+@item -rc_override[:@var{stream_specifier}] @var{override} (@emph{output,per-stream})
+Rate control override for specific intervals, formatted as "int,int,int"
+list separated with slashes. Two first values are the beginning and
+end frame numbers, last one is quantizer to use if positive, or quality
+factor if negative.
+
+@item -deinterlace
+Deinterlace pictures.
+This option is deprecated since the deinterlacing is very low quality.
+Use the yadif filter with @code{-filter:v yadif}.
+@item -ilme
+Force interlacing support in encoder (MPEG-2 and MPEG-4 only).
+Use this option if your input file is interlaced and you want
+to keep the interlaced format for minimum losses.
+The alternative is to deinterlace the input stream with
+@option{-deinterlace}, but deinterlacing introduces losses.
+@item -psnr
+Calculate PSNR of compressed frames.
+@item -vstats
+Dump video coding statistics to @file{vstats_HHMMSS.log}.
+@item -vstats_file @var{file}
+Dump video coding statistics to @var{file}.

+top=1/bottom=0/auto=-1 field first
+@item -dc @var{precision}
+Intra_dc_precision.
+@item -vtag @var{fourcc/tag} (@emph{output})
+Force video tag/fourcc. This is an alias for @code{-tag:v}.
+@item -qphist (@emph{global})
+Show QP histogram
+@item -vbsf @var{bitstream_filter}
+Deprecated see -bsf
+@item -force_key_frames[:@var{stream_specifier}] @var{time}[,@var{time}...] (@emph{output,per-stream})
+Force key frames at the specified timestamps, more precisely at the first
+frames after each specified time.
+This option can be useful to ensure that a seek point is present at a
+chapter mark or any other designated place in the output file.
+The timestamps must be specified in ascending order.

+Set the audio sampling frequency. For output streams it is set by
+default to the frequency of the corresponding input stream. For input
+streams this option only makes sense for audio grabbing devices and raw
+demuxers and is mapped to the corresponding demuxer options.
+@item -aq @var{q} (@emph{output})
+Set the audio quality (codec-specific, VBR). This is an alias for -q:a.
+@item -ac[:@var{stream_specifier}] @var{channels} (@emph{input/output,per-stream})
+Set the number of audio channels. For output streams it is set by
+default to the number of input audio channels. For input streams
+this option only makes sense for audio grabbing devices and raw demuxers
+and is mapped to the corresponding demuxer options.
+@item -an (@emph{output})
+Disable audio recording.
+@item -acodec @var{codec} (@emph{input/output})
+Set the audio codec. This is an alias for @code{-codec:a}.
+@item -sample_fmt[:@var{stream_specifier}] @var{sample_fmt} (@emph{output,per-stream})
+Set the audio sample format. Use @code{-sample_fmts} to get a list

+
+@section Advanced Subtitle options:
+
+@table @option
+
+@item -fix_sub_duration
+Fix subtitles durations. For each subtitle, wait for the next packet in the
+same stream and adjust the duration of the first to avoid overlap. This is
+necessary with some subtitles codecs, especially DVB subtitles, because the
+duration in the original packet is only a rough estimate and the end is
+actually marked by an empty subtitle frame. Failing to use this option when
+necessary can result in exaggerated durations or muxing failures due to
+non-monotonic timestamps.
+
+Note that this option will delay the output of all data until the next
+subtitle packet is decoded: it may increase memory consumption and latency a
+lot.
+
+@end table
+
+@section Advanced options
+
+@table @option
+@item -map [-]@var{input_file_id}[:@var{stream_specifier}][,@var{sync_file_id}[:@var{stream_specifier}]] | @var{[linklabel]} (@emph{output})
+
+Designate one or more input streams as a source for the output file. Each input
+stream is identified by the input file index @var{input_file_id} and
+the input stream index @var{input_stream_id} within the input
+file. Both indices start at 0. If specified,
+@var{sync_file_id}:@var{stream_specifier} sets which input stream
+is used as a presentation sync reference.
+
+The first @code{-map} option on the command line specifies the
+source for output stream 0, the second @code{-map} option specifies
+the source for output stream 1, etc.
+
+A @code{-} character before the stream identifier creates a "negative" mapping.
+It disables matching streams from already created mappings.
+
+An alternative @var{[linklabel]} form will map outputs from complex filter
+graphs (see the @option{-filter_complex} option) to the output file.
+@var{linklabel} must correspond to a defined output link label in the graph.
+
+For example, to map ALL streams from the first input file to output
+@example
+ffmpeg -i INPUT -map 0 output
+@end example
+
+For example, if you have two audio streams in the first input file,
+these streams are identified by "0:0" and "0:1". You can use
+@code{-map} to select which streams to place in an output file. For
+example:
+@example
+ffmpeg -i INPUT -map 0:1 out.wav
+@end example
+will map the input stream in @file{INPUT} identified by "0:1" to
+the (single) output stream in @file{out.wav}.
+
+For example, to select the stream with index 2 from input file
+@file{a.mov} (specified by the identifier "0:2"), and stream with
+index 6 from input @file{b.mov} (specified by the identifier "1:6"),
+and copy them to the output file @file{out.mov}:
+@example
+ffmpeg -i a.mov -i b.mov -c copy -map 0:2 -map 1:6 out.mov
+@end example
+
+To select all video and the third audio stream from an input file:
+@example
+ffmpeg -i INPUT -map 0:v -map 0:a:2 OUTPUT
+@end example
+
+To map all the streams except the second audio, use negative mappings
+@example
+ffmpeg -i INPUT -map 0 -map -0:a:1 OUTPUT
+@end example
+
+Note that using this option disables the default mappings for this output file.
+
+@item -map_channel [@var{input_file_id}.@var{stream_specifier}.@var{channel_id}|-1][:@var{output_file_id}.@var{stream_specifier}]
+Map an audio channel from a given input to an output. If
+@var{output_file_id}.@var{stream_specifier} is not set, the audio channel will
+be mapped on all the audio streams.
+
+Using "-1" instead of
+@var{input_file_id}.@var{stream_specifier}.@var{channel_id} will map a muted
+channel.
+
+For example, assuming @var{INPUT} is a stereo audio file, you can switch the
+two audio channels with the following command:
+@example
+ffmpeg -i INPUT -map_channel 0.0.1 -map_channel 0.0.0 OUTPUT
+@end example
+
+If you want to mute the first channel and keep the second:
+@example
+ffmpeg -i INPUT -map_channel -1 -map_channel 0.0.1 OUTPUT
+@end example
+
+The order of the "-map_channel" option specifies the order of the channels in
+the output stream. The output channel layout is guessed from the number of
+channels mapped (mono if one "-map_channel", stereo if two, etc.). Using "-ac"
+in combination of "-map_channel" makes the channel gain levels to be updated if
+input and output channel layouts don't match (for instance two "-map_channel"
+options and "-ac 6").
+
+You can also extract each channel of an input to specific outputs; the following
+command extracts two channels of the @var{INPUT} audio stream (file 0, stream 0)
+to the respective @var{OUTPUT_CH0} and @var{OUTPUT_CH1} outputs:
+@example
+ffmpeg -i INPUT -map_channel 0.0.0 OUTPUT_CH0 -map_channel 0.0.1 OUTPUT_CH1
+@end example
+
+The following example splits the channels of a stereo input into two separate
+streams, which are put into the same output file:
+@example
+ffmpeg -i stereo.wav -map 0:0 -map 0:0 -map_channel 0.0.0:0.0 -map_channel 0.0.1:0.1 -y out.ogg
+@end example
+
+Note that currently each output stream can only contain channels from a single
+input stream; you can't for example use "-map_channel" to pick multiple input
+audio channels contained in different streams (from the same or different files)
+and merge them into a single output stream. It is therefore not currently
+possible, for example, to turn two separate mono streams into a single stereo
+stream. However splitting a stereo stream into two single channel mono streams
+is possible.
+
+If you need this feature, a possible workaround is to use the @emph{amerge}
+filter. For example, if you need to merge a media (here @file{input.mkv}) with 2
+mono audio streams into one single stereo channel audio stream (and keep the
+video stream), you can use the following command:
+@example
+ffmpeg -i input.mkv -filter_complex "[0:1] [0:2] amerge" -c:a pcm_s16le -c:v copy output.mkv
+@end example
+
+@item -map_metadata[:@var{metadata_spec_out}] @var{infile}[:@var{metadata_spec_in}] (@emph{output,per-metadata})
+Set metadata information of the next output file from @var{infile}. Note that
+those are file indices (zero-based), not filenames.
+Optional @var{metadata_spec_in/out} parameters specify, which metadata to copy.
+A metadata specifier can have the following forms:
+@table @option
+@item @var{g}
+global metadata, i.e. metadata that applies to the whole file
+
+@item @var{s}[:@var{stream_spec}]
+per-stream metadata. @var{stream_spec} is a stream specifier as described
+in the @ref{Stream specifiers} chapter. In an input metadata specifier, the first
+matching stream is copied from. In an output metadata specifier, all matching
+streams are copied to.
+
+@item @var{c}:@var{chapter_index}
+per-chapter metadata. @var{chapter_index} is the zero-based chapter index.
+
+@item @var{p}:@var{program_index}
+per-program metadata. @var{program_index} is the zero-based program index.
+@end table
+If metadata specifier is omitted, it defaults to global.
+
+By default, global metadata is copied from the first input file,
+per-stream and per-chapter metadata is copied along with streams/chapters. These
+default mappings are disabled by creating any mapping of the relevant type. A negative
+file index can be used to create a dummy mapping that just disables automatic copying.
+
+For example to copy metadata from the first stream of the input file to global metadata
+of the output file:
+@example
+ffmpeg -i in.ogg -map_metadata 0:s:0 out.mp3
+@end example
+
+To do the reverse, i.e. copy global metadata to all audio streams:
+@example
+ffmpeg -i in.mkv -map_metadata:s:a 0:g out.mkv
+@end example
+Note that simple @code{0} would work as well in this example, since global
+metadata is assumed by default.
+
+@item -map_chapters @var{input_file_index} (@emph{output})
+Copy chapters from input file with index @var{input_file_index} to the next
+output file. If no chapter mapping is specified, then chapters are copied from
+the first input file with at least one chapter. Use a negative file index to
+disable any chapter copying.
+@item -debug @var{category}
+Print specific debug info.
+@var{category} is a number or a string containing one of the following values:
+@table @samp
+@item bitstream
+@item buffers
+picture buffer allocations
+@item bugs
+@item dct_coeff
+@item er

+@end table
+@item -benchmark (@emph{global})
+Show benchmarking information at the end of an encode.
+Shows CPU time used and maximum memory consumption.
+Maximum memory consumption is not supported on all systems,
+it will usually display as 0 if not supported.
+@item -benchmark_all (@emph{global})
+Show benchmarking information during the encode.
+Shows CPU time used in various steps (audio/video encode/decode).
+@item -timelimit @var{duration} (@emph{global})
+Exit after ffmpeg has been running for @var{duration} seconds.
+@item -dump (@emph{global})
+Dump each input packet to stderr.
+@item -hex (@emph{global})
+When dumping packets, also dump the payload.
+@item -re (@emph{input})
+Read input at native frame rate. Mainly used to simulate a grab device.
+By default @command{ffmpeg} attempts to read the input(s) as fast as possible.
+This option will slow down the reading of the input(s) to the native frame rate
+of the input(s). It is useful for real-time output (e.g. live streaming). If
+your input(s) is coming from some other live streaming source (through HTTP or
+UDP for example) the server might already be in real-time, thus the option will
+likely not be required. On the other hand, this is meaningful if your input(s)
+is a file you are trying to push in real-time.
+@item -loop_input
+Loop over the input stream. Currently it works only for image
+streams. This option is used for automatic FFserver testing.
+This option is deprecated, use -loop 1.
+@item -loop_output @var{number_of_times}
+Repeatedly loop output for formats that support looping such as animated GIF
+(0 will loop the output infinitely).
+This option is deprecated, use -loop.
+@item -vsync @var{parameter}
+Video sync method.
+For compatibility reasons old values can be specified as numbers.
+Newly added values will have to be specified as strings always.
+
+@table @option
+@item 0, passthrough
+Each frame is passed with its timestamp from the demuxer to the muxer.
+@item 1, cfr
+Frames will be duplicated and dropped to achieve exactly the requested
+constant framerate.
+@item 2, vfr
+Frames are passed through with their timestamp or dropped so as to
+prevent 2 frames from having the same timestamp.
+@item drop
+As passthrough but destroys all timestamps, making the muxer generate
+fresh timestamps based on frame-rate.
+@item -1, auto
+Chooses between 1 and 2 depending on muxer capabilities. This is the
+default method.
+@end table
+
+With -map you can select from which stream the timestamps should be
+taken. You can leave either video or audio unchanged and sync the
+remaining stream(s) to the unchanged one.
+
+@item -async @var{samples_per_second}
+Audio sync method. "Stretches/squeezes" the audio stream to match the timestamps,
+the parameter is the maximum samples per second by which the audio is changed.
+-async 1 is a special case where only the start of the audio stream is corrected
+without any later correction.
+This option has been deprecated. Use the @code{asyncts} audio filter instead.
+@item -copyts
+Copy timestamps from input to output.
+@item -copytb @var{mode}
+Specify how to set the encoder timebase when stream copying. @var{mode} is an
+integer numeric value, and can assume one of the following values:
+
+@table @option
+@item 1
+Use the demuxer timebase.
+
+The time base is copied to the output encoder from the corresponding input
+demuxer. This is sometimes required to avoid non monotonically increasing
+timestamps when copying video streams with variable frame rate.
+
+@item 0
+Use the decoder timebase.
+
+The time base is copied to the output encoder from the corresponding input
+decoder.
+
+@item -1
+Try to make the choice automatically, in order to generate a sane output.
+@end table
+
+Default value is -1.
+
+@item -shortest (@emph{output})
+Finish encoding when the shortest input stream ends.
+@item -dts_delta_threshold
+Timestamp discontinuity delta threshold.
+@item -muxdelay @var{seconds} (@emph{input})
+Set the maximum demux-decode delay.
+@item -muxpreload @var{seconds} (@emph{input})
+Set the initial demux-decode delay.
+@item -streamid @var{output-stream-index}:@var{new-value} (@emph{output})
+Assign a new stream-id value to an output stream. This option should be
+specified prior to the output filename to which it applies.
+For the situation where multiple output files exist, a streamid
+may be reassigned to a different value.
+
+For example, to set the stream 0 PID to 33 and the stream 1 PID to 36 for
+an output mpegts file:
+@example
+ffmpeg -i infile -streamid 0:33 -streamid 1:36 out.ts
+@end example
+
+@item -bsf[:@var{stream_specifier}] @var{bitstream_filters} (@emph{output,per-stream})
+Set bitstream filters for matching streams. @var{bistream_filters} is
+a comma-separated list of bitstream filters. Use the @code{-bsfs} option
+to get the list of bitstream filters.
+@example
+ffmpeg -i h264.mp4 -c:v copy -bsf:v h264_mp4toannexb -an out.h264
+@end example
+@example
+ffmpeg -i file.mov -an -vn -bsf:s mov2textsub -c:s copy -f rawvideo sub.txt
+@end example
+
+@item -tag[:@var{stream_specifier}] @var{codec_tag} (@emph{per-stream})
+Force a tag/fourcc for matching streams.
+
+@item -timecode @var{hh}:@var{mm}:@var{ss}SEP@var{ff}
+Specify Timecode for writing. @var{SEP} is ':' for non drop timecode and ';'
+(or '.') for drop.
+@example
+ffmpeg -i input.mpg -timecode 01:02:03.04 -r 30000/1001 -s ntsc output.mpg
+@end example
+
+@item -filter_complex @var{filtergraph} (@emph{global})
+Define a complex filter graph, i.e. one with arbitrary number of inputs and/or
+outputs. For simple graphs -- those with one input and one output of the same
+type -- see the @option{-filter} options. @var{filtergraph} is a description of
+the filter graph, as described in @ref{Filtergraph syntax}.
+
+Input link labels must refer to input streams using the
+@code{[file_index:stream_specifier]} syntax (i.e. the same as @option{-map}
+uses). If @var{stream_specifier} matches multiple streams, the first one will be
+used. An unlabeled input will be connected to the first unused input stream of
+the matching type.
+
+Output link labels are referred to with @option{-map}. Unlabeled outputs are
+added to the first output file.
+
+Note that with this option it is possible to use only lavfi sources without
+normal input files.
+
+For example, to overlay an image over video
+@example
+ffmpeg -i video.mkv -i image.png -filter_complex '[0:v][1:v]overlay[out]' -map
+'[out]' out.mkv
+@end example
+Here @code{[0:v]} refers to the first video stream in the first input file,
+which is linked to the first (main) input of the overlay filter. Similarly the
+first video stream in the second input is linked to the second (overlay) input
+of overlay.
+
+Assuming there is only one video stream in each input file, we can omit input
+labels, so the above is equivalent to
+@example
+ffmpeg -i video.mkv -i image.png -filter_complex 'overlay[out]' -map
+'[out]' out.mkv
+@end example
+
+Furthermore we can omit the output label and the single output from the filter
+graph will be added to the output file automatically, so we can simply write
+@example
+ffmpeg -i video.mkv -i image.png -filter_complex 'overlay' out.mkv
+@end example
+
+To generate 5 seconds of pure red video using lavfi @code{color} source:
+@example
+ffmpeg -filter_complex 'color=red' -t 5 out.mkv
+@end example
+@end table
+
+As a special exception, you can use a bitmap subtitle stream as input: it
+will be converted into a video with the same size as the largest video in
+the file, or 720×576 if no video is present. Note that this is an
+experimental and temporary solution. It will be removed once libavfilter has
+proper support for subtitles.
+
+For example, to hardcode subtitles on top of a DVB-T recording stored in
+MPEG-TS format, delaying the subtitles by 1 second:
+@example
+ffmpeg -i input.ts -filter_complex \
+ '[#0x2ef] setpts=PTS+1/TB [sub] ; [#0x2d0] [sub] overlay' \
+ -sn -map '#0x2dc' output.mkv
+@end example
+(0x2d0, 0x2dc and 0x2ef are the MPEG-TS PIDs of respectively the video,
+audio and subtitles streams; 0:0, 0:3 and 0:7 would have worked too)
+
+@section Preset files
+A preset file contains a sequence of @var{option}=@var{value} pairs,
+one for each line, specifying a sequence of options which would be
+awkward to specify on the command line. Lines starting with the hash
+('#') character are ignored and are used to provide comments. Check
+the @file{presets} directory in the FFmpeg source tree for examples.
+
+Preset files are specified with the @code{vpre}, @code{apre},
+@code{spre}, and @code{fpre} options. The @code{fpre} option takes the
+filename of the preset instead of a preset name as input and can be
+used for any kind of codec. For the @code{vpre}, @code{apre}, and
+@code{spre} options, the options specified in a preset file are
+applied to the currently selected codec of the same type as the preset
+option.
+
+The argument passed to the @code{vpre}, @code{apre}, and @code{spre}
+preset options identifies the preset file to use according to the
+following rules:
+
+First ffmpeg searches for a file named @var{arg}.ffpreset in the
+directories @file{$FFMPEG_DATADIR} (if set), and @file{$HOME/.ffmpeg}, and in
+the datadir defined at configuration time (usually @file{PREFIX/share/ffmpeg})
+or in a @file{ffpresets} folder along the executable on win32,
+in that order. For example, if the argument is @code{libvpx-1080p}, it will
+search for the file @file{libvpx-1080p.ffpreset}.
+
+If no such file is found, then ffmpeg will search for a file named
+@var{codec_name}-@var{arg}.ffpreset in the above-mentioned
+directories, where @var{codec_name} is the name of the codec to which
+the preset file options will be applied. For example, if you select
+the video codec with @code{-vcodec libvpx} and use @code{-vpre 1080p},
+then it will search for the file @file{libvpx-1080p.ffpreset}.
+@c man end OPTIONS
+
+@chapter Tips
+@c man begin TIPS
+
+@itemize
+@item
+For streaming at very low bitrate application, use a low frame rate
+and a small GOP size. This is especially true for RealVideo where
+the Linux player does not seem to be very fast, so it can miss
+frames. An example is:
+
+@example
+ffmpeg -g 3 -r 3 -t 10 -b:v 50k -s qcif -f rv10 /tmp/b.rm
+@end example
+
+@item
+The parameter 'q' which is displayed while encoding is the current
+quantizer. The value 1 indicates that a very good quality could
+be achieved. The value 31 indicates the worst quality. If q=31 appears
+too often, it means that the encoder cannot compress enough to meet
+your bitrate. You must either increase the bitrate, decrease the
+frame rate or decrease the frame size.
+
+@item
+If your computer is not fast enough, you can speed up the
+compression at the expense of the compression ratio. You can use
+'-me zero' to speed up motion estimation, and '-g 0' to disable
+motion estimation completely (you have only I-frames, which means it
+is about as good as JPEG compression).
+
+@item
+To have very low audio bitrates, reduce the sampling frequency
+(down to 22050 Hz for MPEG audio, 22050 or 11025 for AC-3).
+
+@item
+To have a constant quality (but a variable bitrate), use the option
+'-qscale n' when 'n' is between 1 (excellent quality) and 31 (worst
+quality).
+
+@end itemize
+@c man end TIPS
+
+@chapter Examples
+@c man begin EXAMPLES
+
+@section Preset files
+
+A preset file contains a sequence of @var{option=value} pairs, one for
+each line, specifying a sequence of options which can be specified also on
+the command line. Lines starting with the hash ('#') character are ignored and
+are used to provide comments. Empty lines are also ignored. Check the
+@file{presets} directory in the FFmpeg source tree for examples.
+
+Preset files are specified with the @code{pre} option, this option takes a
+preset name as input. FFmpeg searches for a file named @var{preset_name}.avpreset in
+the directories @file{$AVCONV_DATADIR} (if set), and @file{$HOME/.ffmpeg}, and in
+the data directory defined at configuration time (usually @file{$PREFIX/share/ffmpeg})
+in that order. For example, if the argument is @code{libx264-max}, it will
+search for the file @file{libx264-max.avpreset}.
+
+@section Video and Audio grabbing
+
+If you specify the input format and device then ffmpeg can grab video
+and audio directly.
+
+@example
+ffmpeg -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg
+@end example
+
+Or with an ALSA audio source (mono input, card id 1) instead of OSS:
+@example
+ffmpeg -f alsa -ac 1 -i hw:1 -f video4linux2 -i /dev/video0 /tmp/out.mpg
+@end example
+
+Note that you must activate the right video source and channel before
+launching ffmpeg with any TV viewer such as
+@uref{http://linux.bytesex.org/xawtv/, xawtv} by Gerd Knorr. You also
+have to set the audio recording levels correctly with a
+standard mixer.
+
+@section X11 grabbing
+
+Grab the X11 display with ffmpeg via
+
+@example
+ffmpeg -f x11grab -s cif -r 25 -i :0.0 /tmp/out.mpg
+@end example
+
+0.0 is display.screen number of your X11 server, same as
+the DISPLAY environment variable.
+
+@example
+ffmpeg -f x11grab -s cif -r 25 -i :0.0+10,20 /tmp/out.mpg
+@end example
+
+0.0 is display.screen number of your X11 server, same as the DISPLAY environment
+variable. 10 is the x-offset and 20 the y-offset for the grabbing.
+
+@section Video and Audio file format conversion
+
+Any supported file format and protocol can serve as input to ffmpeg:
+
+Examples:
+@itemize
+@item
+You can use YUV files as input:
+
+@example
+ffmpeg -i /tmp/test%d.Y /tmp/out.mpg
+@end example
+
+It will use the files:
+@example
+/tmp/test0.Y, /tmp/test0.U, /tmp/test0.V,
+/tmp/test1.Y, /tmp/test1.U, /tmp/test1.V, etc...
+@end example
+
+The Y files use twice the resolution of the U and V files. They are
+raw files, without header. They can be generated by all decent video
+decoders. You must specify the size of the image with the @option{-s} option
+if ffmpeg cannot guess it.
+
+@item
+You can input from a raw YUV420P file:
+
+@example
+ffmpeg -i /tmp/test.yuv /tmp/out.avi
+@end example
+
+test.yuv is a file containing raw YUV planar data. Each frame is composed
+of the Y plane followed by the U and V planes at half vertical and
+horizontal resolution.
+
+@item
+You can output to a raw YUV420P file:
+
+@example
+ffmpeg -i mydivx.avi hugefile.yuv
+@end example
+
+@item
+You can set several input files and output files:
+
+@example
+ffmpeg -i /tmp/a.wav -s 640x480 -i /tmp/a.yuv /tmp/a.mpg
+@end example
+
+Converts the audio file a.wav and the raw YUV video file a.yuv
+to MPEG file a.mpg.
+
+@item
+You can also do audio and video conversions at the same time:
+
+@example
+ffmpeg -i /tmp/a.wav -ar 22050 /tmp/a.mp2
+@end example
+
+Converts a.wav to MPEG audio at 22050 Hz sample rate.
+
+@item
+You can encode to several formats at the same time and define a
+mapping from input stream to output streams:
+
+@example
+ffmpeg -i /tmp/a.wav -map 0:a -b:a 64k /tmp/a.mp2 -map 0:a -b:a 128k /tmp/b.mp2
+@end example
+
+Converts a.wav to a.mp2 at 64 kbits and to b.mp2 at 128 kbits. '-map
+file:index' specifies which input stream is used for each output
+stream, in the order of the definition of output streams.
+
+@item
+You can transcode decrypted VOBs:
+
+@example
+ffmpeg -i snatch_1.vob -f avi -c:v mpeg4 -b:v 800k -g 300 -bf 2 -c:a libmp3lame -b:a 128k snatch.avi
+@end example
+
+This is a typical DVD ripping example; the input is a VOB file, the
+output an AVI file with MPEG-4 video and MP3 audio. Note that in this
+command we use B-frames so the MPEG-4 stream is DivX5 compatible, and
+GOP size is 300 which means one intra frame every 10 seconds for 29.97fps
+input video. Furthermore, the audio stream is MP3-encoded so you need
+to enable LAME support by passing @code{--enable-libmp3lame} to configure.
+The mapping is particularly useful for DVD transcoding
+to get the desired audio language.
+
+NOTE: To see the supported input formats, use @code{ffmpeg -formats}.
+
+@item
+You can extract images from a video, or create a video from many images:
+
+For extracting images from a video:
+@example
+ffmpeg -i foo.avi -r 1 -s WxH -f image2 foo-%03d.jpeg
+@end example
+
+This will extract one video frame per second from the video and will
+output them in files named @file{foo-001.jpeg}, @file{foo-002.jpeg},
+etc. Images will be rescaled to fit the new WxH values.
+
+If you want to extract just a limited number of frames, you can use the
+above command in combination with the -vframes or -t option, or in
+combination with -ss to start extracting from a certain point in time.
+
+For creating a video from many images:
+@example
+ffmpeg -f image2 -i foo-%03d.jpeg -r 12 -s WxH foo.avi
+@end example
+
+The syntax @code{foo-%03d.jpeg} specifies to use a decimal number
+composed of three digits padded with zeroes to express the sequence
+number. It is the same syntax supported by the C printf function, but
+only formats accepting a normal integer are suitable.
+
+When importing an image sequence, -i also supports expanding
+shell-like wildcard patterns (globbing) internally, by selecting the
+image2-specific @code{-pattern_type glob} option.
+
+For example, for creating a video from filenames matching the glob pattern
+@code{foo-*.jpeg}:
+@example
+ffmpeg -f image2 -pattern_type glob -i 'foo-*.jpeg' -r 12 -s WxH foo.avi
+@end example
+
+@item
+You can put many streams of the same type in the output:
+
+@example
+ffmpeg -i test1.avi -i test2.avi -map 0.3 -map 0.2 -map 0.1 -map 0.0 -c copy test12.nut
+@end example
+
+The resulting output file @file{test12.avi} will contain first four streams from
+the input file in reverse order.
+
+@item
+To force CBR video output:
+@example
+ffmpeg -i myfile.avi -b 4000k -minrate 4000k -maxrate 4000k -bufsize 1835k out.m2v
+@end example
+
+@item
+The four options lmin, lmax, mblmin and mblmax use 'lambda' units,
+but you may use the QP2LAMBDA constant to easily convert from 'q' units:
+@example
+ffmpeg -i src.ext -lmax 21*QP2LAMBDA dst.ext

+
+@example
+@c man begin SYNOPSIS
+ffprobe [options] [@file{input_file}]
+@c man end
+@end example
+
+@chapter Description
+@c man begin DESCRIPTION
+
+ffprobe gathers information from multimedia streams and prints it in
+human- and machine-readable fashion.
+
+For example it can be used to check the format of the container used
+by a multimedia stream and the format and type of each media stream
+contained in it.
+
+If a filename is specified in input, ffprobe will try to open and
+probe the file content. If the file cannot be opened or recognized as
+a multimedia file, a positive exit code is returned.
+
+ffprobe may be employed both as a standalone application or in
+combination with a textual filter, which may perform more
+sophisticated processing, e.g. statistical processing or plotting.
+
+Options are used to list some of the formats supported by ffprobe or
+for specifying which information to display, and for setting how
+ffprobe will show it.
+
+ffprobe output is designed to be easily parsable by a textual filter,
+and consists of one or more sections of a form defined by the selected
+writer, which is specified by the @option{print_format} option.
+
+Metadata tags stored in the container or in the streams are recognized
+and printed in the corresponding "FORMAT" or "STREAM" section.
+
+@c man end
+
+@chapter Options
+@c man begin OPTIONS
+
+@include avtools-common-opts.texi
+
+@section Main options
+
+@table @option
+
+@item -f @var{format}
+Force format to use.
+
+@item -unit
+Show the unit of the displayed values.
+
+@item -prefix
+Use SI prefixes for the displayed values.
+Unless the "-byte_binary_prefix" option is used all the prefixes
+are decimal.
+
+@item -byte_binary_prefix
+Force the use of binary prefixes for byte values.
+
+@item -sexagesimal
+Use sexagesimal format HH:MM:SS.MICROSECONDS for time values.
+
+@item -pretty
+Prettify the format of the displayed values, it corresponds to the
+options "-unit -prefix -byte_binary_prefix -sexagesimal".
+
+@item -of, -print_format @var{writer_name}[=@var{writer_options}]
+Set the output printing format.
+
+@var{writer_name} specifies the name of the writer, and
+@var{writer_options} specifies the options to be passed to the writer.
+
+For example for printing the output in JSON format, specify:
+@example
+-print_format json
+@end example
+
+For more details on the available output printing formats, see the
+Writers section below.
+
+@item -select_streams @var{stream_specifier}
+Select only the streams specified by @var{stream_specifier}. This
+option affects only the options related to streams
+(e.g. @code{show_streams}, @code{show_packets}, etc.).
+
+For example to show only audio streams, you can use the command:
+@example
+ffprobe -show_streams -select_streams a INPUT
+@end example
+
+To show only video packets belonging to the video stream with index 1:
+@example
+ffprobe -show_packets -select_streams v:1 INPUT
+@end example
+
+@item -show_data
+Show payload data, as an hexadecimal and ASCII dump. Coupled with
+@option{-show_packets}, it will dump the packets' data. Coupled with
+@option{-show_streams}, it will dump the codec extradata.
+
+The dump is printed as the "data" field. It may contain newlines.
+
+@item -show_error
+Show information about the error found when trying to probe the input.
+
+The error information is printed within a section with name "ERROR".
+
+@item -show_format
+Show information about the container format of the input multimedia
+stream.
+
+All the container format information is printed within a section with
+name "FORMAT".
+
+@item -show_format_entry @var{name}
+Like @option{-show_format}, but only prints the specified entry of the
+container format information, rather than all. This option may be given more
+than once, then all specified entries will be shown.
+
+@item -show_packets
+Show information about each packet contained in the input multimedia
+stream.
+
+The information for each single packet is printed within a dedicated
+section with name "PACKET".
+

+Show information about each frame contained in the input multimedia
+stream.
+
+The information for each single frame is printed within a dedicated
+section with name "FRAME".

+multimedia stream.
+
+Each media stream information is printed within a dedicated section
+with name "STREAM".
+
+@item -count_frames
+Count the number of frames per stream and report it in the
+corresponding stream section.
+
+@item -count_packets
+Count the number of packets per stream and report it in the
+corresponding stream section.
+
+@item -show_private_data, -private
+Show private data, that is data depending on the format of the

+This option is enabled by default, but you may need to disable it
+for specific uses, for example when creating XSD-compliant XML output.
+
+@item -show_program_version
+Show information related to program version.
+
+Version information is printed within a section with name
+"PROGRAM_VERSION".
+
+@item -show_library_versions
+Show information related to library versions.
+
+Version information for each library is printed within a section with
+name "LIBRARY_VERSION".
+
+@item -show_versions
+Show information related to program and library versions. This is the
+equivalent of setting both @option{-show_program_version} and
+@option{-show_library_versions} options.
+
+@item -bitexact
+Force bitexact output, useful to produce output which is not dependent
+on the specific build.
+
+@item -i @var{input_file}
+Read @var{input_file}.
+
+@end table
+@c man end
+
+@chapter Writers
+@c man begin WRITERS
+
+A writer defines the output format adopted by @command{ffprobe}, and will be
+used for printing all the parts of the output.
+
+A writer may accept one or more arguments, which specify the options to
+adopt.
+
+A description of the currently available writers follows.
+
+@section default
+Default format.
+
+Print each section in the form:
+@example
+[SECTION]
+key1=val1
+...
+keyN=valN
+[/SECTION]
+@end example
+
+Metadata tags are printed as a line in the corresponding FORMAT or
+STREAM section, and are prefixed by the string "TAG:".
+
+This writer accepts options as a list of @var{key}=@var{value} pairs,
+separated by ":".
+
+A description of the accepted options follows.
+
+@table @option
+
+@item nokey, nk
+If set to 1 specify not to print the key of each field. Default value
+is 0.
+
+@item noprint_wrappers, nw
+If set to 1 specify not to print the section header and footer.
+Default value is 0.
+@end table
+
+@section compact, csv
+Compact and CSV format.
+
+The @code{csv} writer is equivalent to @code{compact}, but supports
+different defaults.
+
+Each section is printed on a single line.
+If no option is specifid, the output has the form:
+@example
+section|key1=val1| ... |keyN=valN
+@end example
+
+Metadata tags are printed in the corresponding "format" or "stream"
+section. A metadata tag key, if printed, is prefixed by the string
+"tag:".
+
+This writer accepts options as a list of @var{key}=@var{value} pairs,
+separated by ":".
+
+The description of the accepted options follows.
+
+@table @option
+
+@item item_sep, s
+Specify the character to use for separating fields in the output line.
+It must be a single printable character, it is "|" by default ("," for
+the @code{csv} writer).
+
+@item nokey, nk
+If set to 1 specify not to print the key of each field. Its default
+value is 0 (1 for the @code{csv} writer).
+
+@item escape, e
+Set the escape mode to use, default to "c" ("csv" for the @code{csv}
+writer).
+
+It can assume one of the following values:
+@table @option
+@item c
+Perform C-like escaping. Strings containing a newline ('\n'), carriage
+return ('\r'), a tab ('\t'), a form feed ('\f'), the escaping
+character ('\') or the item separator character @var{SEP} are escaped using C-like fashioned
+escaping, so that a newline is converted to the sequence "\n", a
+carriage return to "\r", '\' to "\\" and the separator @var{SEP} is
+converted to "\@var{SEP}".
+
+@item csv
+Perform CSV-like escaping, as described in RFC4180. Strings
+containing a newline ('\n'), a carriage return ('\r'), a double quote
+('"'), or @var{SEP} are enclosed in double-quotes.
+
+@item none
+Perform no escaping.
+@end table
+
+@item print_section, p
+Print the section name at the begin of each line if the value is
+@code{1}, disable it with value set to @code{0}. Default value is
+@code{1}.
+
+@end table
+
+@section flat
+Flat format.
+
+A free-form output where each line contains an explicit key=value, such as
+"streams.stream.3.tags.foo=bar". The output is shell escaped, so it can be
+directly embedded in sh scripts as long as the separator character is an
+alphanumeric character or an underscore (see @var{sep_char} option).
+
+This writer accepts options as a list of @var{key}=@var{value} pairs,
+separated by ":".
+
+The description of the accepted options follows.
+
+@table @option
+@item sep_char, s
+Separator character used to separate the chapter, the section name, IDs and
+potential tags in the printed field key.
+
+Default value is '.'.
+
+@item hierarchical, h
+Specify if the section name specification should be hierarchical. If
+set to 1, and if there is more than one section in the current
+chapter, the section name will be prefixed by the name of the
+chapter. A value of 0 will disable this behavior.
+
+Default value is 1.
+@end table
+
+@section ini
+INI format output.
+
+Print output in an INI based format.
+
+The following conventions are adopted:
+
+@itemize
+@item
+all key and values are UTF-8
+@item
+'.' is the subgroup separator
+@item
+newline, '\t', '\f', '\b' and the following characters are escaped
+@item
+'\' is the escape character
+@item
+'#' is the comment indicator
+@item
+'=' is the key/value separator
+@item
+':' is not used but usually parsed as key/value separator
+@end itemize
+
+This writer accepts options as a list of @var{key}=@var{value} pairs,
+separated by ":".
+
+The description of the accepted options follows.
+
+@table @option
+@item hierarchical, h
+Specify if the section name specification should be hierarchical. If
+set to 1, and if there is more than one section in the current
+chapter, the section name will be prefixed by the name of the
+chapter. A value of 0 will disable this behavior.
+
+Default value is 1.
+@end table
+
+@section json
+JSON based format.
+
+Each section is printed using JSON notation.
+
+This writer accepts options as a list of @var{key}=@var{value} pairs,
+separated by ":".
+
+The description of the accepted options follows.
+
+@table @option
+
+@item compact, c
+If set to 1 enable compact output, that is each section will be
+printed on a single line. Default value is 0.
+@end table
+
+For more information about JSON, see @url{http://www.json.org/}.
+
+@section xml
+XML based format.
+
+The XML output is described in the XML schema description file
+@file{ffprobe.xsd} installed in the FFmpeg datadir.
+
+An updated version of the schema can be retrieved at the url
+@url{http://www.ffmpeg.org/schema/ffprobe.xsd}, which redirects to the
+latest schema committed into the FFmpeg development source code tree.
+
+Note that the output issued will be compliant to the
+@file{ffprobe.xsd} schema only when no special global output options
+(@option{unit}, @option{prefix}, @option{byte_binary_prefix},
+@option{sexagesimal} etc.) are specified.
+
+This writer accepts options as a list of @var{key}=@var{value} pairs,
+separated by ":".
+
+The description of the accepted options follows.
+
+@table @option
+
+@item fully_qualified, q
+If set to 1 specify if the output should be fully qualified. Default
+value is 0.
+This is required for generating an XML file which can be validated
+through an XSD file.
+
+@item xsd_compliant, x
+If set to 1 perform more checks for ensuring that the output is XSD
+compliant. Default value is 0.
+This option automatically sets @option{fully_qualified} to 1.
+@end table
+
+For more information about the XML format, see
+@url{http://www.w3.org/XML/}.

+
+@chapter Description
+@c man begin DESCRIPTION
+
+ffserver is a streaming server for both audio and video. It supports
+
+several live feeds, streaming from files and time shifting on live feeds
+(you can seek to positions in the past on each live feed, provided you
+specify a big enough feed storage in ffserver.conf).
+
+ffserver runs in daemon mode by default; that is, it puts itself in
+the background and detaches from its TTY, unless it is launched in
+debug mode or a NoDaemon option is specified in the configuration
+file.
+
+This documentation covers only the streaming aspects of ffserver /
+ffmpeg. All questions about parameters for ffmpeg, codec questions,
+etc. are not covered here. Read @file{ffmpeg.html} for more
+information.
+
+@section How does it work?
+
+ffserver receives prerecorded files or FFM streams from some ffmpeg
+instance as input, then streams them over RTP/RTSP/HTTP.
+
+An ffserver instance will listen on some port as specified in the
+configuration file. You can launch one or more instances of ffmpeg and
+send one or more FFM streams to the port where ffserver is expecting
+to receive them. Alternately, you can make ffserver launch such ffmpeg
+instances at startup.
+
+Input streams are called feeds, and each one is specified by a <Feed>
+section in the configuration file.
+
+For each feed you can have different output streams in various
+formats, each one specified by a <Stream> section in the configuration
+file.
+
+@section Status stream
+
+ffserver supports an HTTP interface which exposes the current status
+of the server.
+
+Simply point your browser to the address of the special status stream
+specified in the configuration file.
+
+For example if you have:
+@example
+<Stream status.html>
+Format status
+
+# Only allow local people to get the status
+ACL allow localhost
+ACL allow 192.168.0.0 192.168.255.255
+</Stream>
+@end example
+
+then the server will post a page with the status information when
+the special stream @file{status.html} is requested.
+
+@section What can this do?
+
+When properly configured and running, you can capture video and audio in real
+time from a suitable capture card, and stream it out over the Internet to
+either Windows Media Player or RealAudio player (with some restrictions).
+
+It can also stream from files, though that is currently broken. Very often, a
+web server can be used to serve up the files just as well.
+
+It can stream prerecorded video from .ffm files, though it is somewhat tricky
+to make it work correctly.
+
+@section What do I need?
+
+I use Linux on a 900 MHz Duron with a cheapo Bt848 based TV capture card. I'm
+using stock Linux 2.4.17 with the stock drivers. [Actually that isn't true,
+I needed some special drivers for my motherboard-based sound card.]
+
+I understand that FreeBSD systems work just fine as well.
+
+@section How do I make it work?
+
+First, build the kit. It *really* helps to have installed LAME first. Then when
+you run the ffserver ./configure, make sure that you have the
+@code{--enable-libmp3lame} flag turned on.
+
+LAME is important as it allows for streaming audio to Windows Media Player.
+Don't ask why the other audio types do not work.
+
+As a simple test, just run the following two command lines where INPUTFILE
+is some file which you can decode with ffmpeg:
+
+@example
+ffserver -f doc/ffserver.conf &
+ffmpeg -i INPUTFILE http://localhost:8090/feed1.ffm
+@end example
+
+At this point you should be able to go to your Windows machine and fire up
+Windows Media Player (WMP). Go to Open URL and enter
+
+@example
+ http://<linuxbox>:8090/test.asf
+@end example
+
+You should (after a short delay) see video and hear audio.
+
+WARNING: trying to stream test1.mpg doesn't work with WMP as it tries to
+transfer the entire file before starting to play.
+The same is true of AVI files.
+
+@section What happens next?
+
+You should edit the ffserver.conf file to suit your needs (in terms of
+frame rates etc). Then install ffserver and ffmpeg, write a script to start
+them up, and off you go.
+
+@section Troubleshooting
+
+@subsection I don't hear any audio, but video is fine.
+
+Maybe you didn't install LAME, or got your ./configure statement wrong. Check
+the ffmpeg output to see if a line referring to MP3 is present. If not, then
+your configuration was incorrect. If it is, then maybe your wiring is not
+set up correctly. Maybe the sound card is not getting data from the right
+input source. Maybe you have a really awful audio interface (like I do)
+that only captures in stereo and also requires that one channel be flipped.
+If you are one of these people, then export 'AUDIO_FLIP_LEFT=1' before
+starting ffmpeg.
+
+@subsection The audio and video lose sync after a while.
+
+Yes, they do.
+
+@subsection After a long while, the video update rate goes way down in WMP.
+
+Yes, it does. Who knows why?
+
+@subsection WMP 6.4 behaves differently to WMP 7.
+
+Yes, it does. Any thoughts on this would be gratefully received. These
+differences extend to embedding WMP into a web page. [There are two
+object IDs that you can use: The old one, which does not play well, and
+the new one, which does (both tested on the same system). However,
+I suspect that the new one is not available unless you have installed WMP 7].
+
+@section What else can it do?
+
+You can replay video from .ffm files that was recorded earlier.
+However, there are a number of caveats, including the fact that the
+ffserver parameters must match the original parameters used to record the
+file. If they do not, then ffserver deletes the file before recording into it.
+(Now that I write this, it seems broken).
+
+You can fiddle with many of the codec choices and encoding parameters, and
+there are a bunch more parameters that you cannot control. Post a message
+to the mailing list if there are some 'must have' parameters. Look in
+ffserver.conf for a list of the currently available controls.
+
+It will automatically generate the ASX or RAM files that are often used
+in browsers. These files are actually redirections to the underlying ASF
+or RM file. The reason for this is that the browser often fetches the
+entire file before starting up the external viewer. The redirection files
+are very small and can be transferred quickly. [The stream itself is
+often 'infinite' and thus the browser tries to download it and never
+finishes.]
+
+@section Tips
+
+* When you connect to a live stream, most players (WMP, RA, etc) want to
+buffer a certain number of seconds of material so that they can display the
+signal continuously. However, ffserver (by default) starts sending data
+in realtime. This means that there is a pause of a few seconds while the
+buffering is being done by the player. The good news is that this can be
+cured by adding a '?buffer=5' to the end of the URL. This means that the
+stream should start 5 seconds in the past -- and so the first 5 seconds
+of the stream are sent as fast as the network will allow. It will then
+slow down to real time. This noticeably improves the startup experience.
+
+You can also add a 'Preroll 15' statement into the ffserver.conf that will
+add the 15 second prebuffering on all requests that do not otherwise
+specify a time. In addition, ffserver will skip frames until a key_frame
+is found. This further reduces the startup delay by not transferring data
+that will be discarded.
+
+* You may want to adjust the MaxBandwidth in the ffserver.conf to limit
+the amount of bandwidth consumed by live streams.
+
+@section Why does the ?buffer / Preroll stop working after a time?
+
+It turns out that (on my machine at least) the number of frames successfully
+grabbed is marginally less than the number that ought to be grabbed. This
+means that the timestamp in the encoded data stream gets behind realtime.
+This means that if you say 'Preroll 10', then when the stream gets 10
+or more seconds behind, there is no Preroll left.
+
+Fixing this requires a change in the internals of how timestamps are
+handled.
+
+@section Does the @code{?date=} stuff work.
+
+Yes (subject to the limitation outlined above). Also note that whenever you
+start ffserver, it deletes the ffm file (if any parameters have changed),
+thus wiping out what you had recorded before.
+
+The format of the @code{?date=xxxxxx} is fairly flexible. You should use one
+of the following formats (the 'T' is literal):
+
+@example
+* YYYY-MM-DDTHH:MM:SS (localtime)
+* YYYY-MM-DDTHH:MM:SSZ (UTC)
+@end example
+
+You can omit the YYYY-MM-DD, and then it refers to the current day. However
+note that @samp{?date=16:00:00} refers to 16:00 on the current day -- this
+may be in the future and so is unlikely to be useful.
+
+You use this by adding the ?date= to the end of the URL for the stream.
+For example: @samp{http://localhost:8080/test.asf?date=2002-07-26T23:05:00}.

+Filter design
+=============
+
+This document explains guidelines that should be observed (or ignored with
+good reason) when writing filters for libavfilter.
+
+In this document, the word “frame” indicates either a video frame or a group
+of audio samples, as stored in an AVFilterBuffer structure.
+
+
+Format negotiation
+==================
+
+ The query_formats method should set, for each input and each output links,
+ the list of supported formats.
+
+ For video links, that means pixel format. For audio links, that means
+ channel layout, and sample format (the sample packing is implied by the
+ sample format).
+
+ The lists are not just lists, they are references to shared objects. When
+ the negotiation mechanism computes the intersection of the formats
+ supported at each ends of a link, all references to both lists are
+ replaced with a reference to the intersection. And when a single format is
+ eventually chosen for a link amongst the remaining list, again, all
+ references to the list are updated.
+
+ That means that if a filter requires that its input and output have the
+ same format amongst a supported list, all it has to do is use a reference
+ to the same list of formats.
+
+
+Buffer references ownership and permissions
+===========================================
+
+ Principle
+ ---------
+
+ Audio and video data are voluminous; the buffer and buffer reference
+ mechanism is intended to avoid, as much as possible, expensive copies of
+ that data while still allowing the filters to produce correct results.
+
+ The data is stored in buffers represented by AVFilterBuffer structures.
+ They must not be accessed directly, but through references stored in
+ AVFilterBufferRef structures. Several references can point to the
+ same buffer; the buffer is automatically deallocated once all
+ corresponding references have been destroyed.
+
+ The characteristics of the data (resolution, sample rate, etc.) are
+ stored in the reference; different references for the same buffer can
+ show different characteristics. In particular, a video reference can
+ point to only a part of a video buffer.
+
+ A reference is usually obtained as input to the start_frame or
+ filter_samples method or requested using the ff_get_video_buffer or
+ ff_get_audio_buffer functions. A new reference on an existing buffer can
+ be created with the avfilter_ref_buffer. A reference is destroyed using
+ the avfilter_unref_bufferp function.
+
+ Reference ownership
+ -------------------
+
+ At any time, a reference “belongs” to a particular piece of code,
+ usually a filter. With a few caveats that will be explained below, only
+ that piece of code is allowed to access it. It is also responsible for
+ destroying it, although this is sometimes done automatically (see the
+ section on link reference fields).
+
+ Here are the (fairly obvious) rules for reference ownership:
+
+ * A reference received by the start_frame or filter_samples method
+ belong to the corresponding filter.
+
+ Special exception: for video references: the reference may be used
+ internally for automatic copying and must not be destroyed before
+ end_frame; it can be given away to ff_start_frame.
+
+ * A reference passed to ff_start_frame or ff_filter_samples is given
+ away and must no longer be used.
+
+ * A reference created with avfilter_ref_buffer belongs to the code that
+ created it.
+
+ * A reference obtained with ff_get_video_buffer or ff_get_audio_buffer
+ belongs to the code that requested it.
+
+ * A reference given as return value by the get_video_buffer or
+ get_audio_buffer method is given away and must no longer be used.
+
+ Link reference fields
+ ---------------------
+
+ The AVFilterLink structure has a few AVFilterBufferRef fields. Here are
+ the rules to handle them:
+
+ * cur_buf is set before the start_frame and filter_samples methods to
+ the same reference given as argument to the methods and belongs to the
+ destination filter of the link. If it has not been cleared after
+ end_frame or filter_samples, libavfilter will automatically destroy
+ the reference; therefore, any filter that needs to keep the reference
+ for longer must set cur_buf to NULL.
+
+ * out_buf belongs to the source filter of the link and can be used to
+ store a reference to the buffer that has been sent to the destination.
+ If it is not NULL after end_frame or filter_samples, libavfilter will
+ automatically destroy the reference.
+
+ If a video input pad does not have a start_frame method, the default
+ method will request a buffer on the first output of the filter, store
+ the reference in out_buf and push a second reference to the output.
+
+ * src_buf, cur_buf_copy and partial_buf are used by libavfilter
+ internally and must not be accessed by filters.
+
+ Reference permissions
+ ---------------------
+
+ The AVFilterBufferRef structure has a perms field that describes what
+ the code that owns the reference is allowed to do to the buffer data.
+ Different references for the same buffer can have different permissions.
+
+ For video filters, the permissions only apply to the parts of the buffer
+ that have already been covered by the draw_slice method.
+
+ The value is a binary OR of the following constants:
+
+ * AV_PERM_READ: the owner can read the buffer data; this is essentially
+ always true and is there for self-documentation.
+
+ * AV_PERM_WRITE: the owner can modify the buffer data.
+
+ * AV_PERM_PRESERVE: the owner can rely on the fact that the buffer data
+ will not be modified by previous filters.
+
+ * AV_PERM_REUSE: the owner can output the buffer several times, without
+ modifying the data in between.
+
+ * AV_PERM_REUSE2: the owner can output the buffer several times and
+ modify the data in between (useless without the WRITE permissions).
+
+ * AV_PERM_ALIGN: the owner can access the data using fast operations
+ that require data alignment.
+
+ The READ, WRITE and PRESERVE permissions are about sharing the same
+ buffer between several filters to avoid expensive copies without them
+ doing conflicting changes on the data.
+
+ The REUSE and REUSE2 permissions are about special memory for direct
+ rendering. For example a buffer directly allocated in video memory must
+ not modified once it is displayed on screen, or it will cause tearing;
+ it will therefore not have the REUSE2 permission.
+
+ The ALIGN permission is about extracting part of the buffer, for
+ copy-less padding or cropping for example.
+
+
+ References received on input pads are guaranteed to have all the
+ permissions stated in the min_perms field and none of the permissions
+ stated in the rej_perms.
+
+ References obtained by ff_get_video_buffer and ff_get_audio_buffer are
+ guaranteed to have at least all the permissions requested as argument.
+
+ References created by avfilter_ref_buffer have the same permissions as
+ the original reference minus the ones explicitly masked; the mask is
+ usually ~0 to keep the same permissions.
+
+ Filters should remove permissions on reference they give to output
+ whenever necessary. It can be automatically done by setting the
+ rej_perms field on the output pad.
+
+ Here are a few guidelines corresponding to common situations:
+
+ * Filters that modify and forward their frame (like drawtext) need the
+ WRITE permission.
+
+ * Filters that read their input to produce a new frame on output (like
+ scale) need the READ permission on input and and must request a buffer
+ with the WRITE permission.
+
+ * Filters that intend to keep a reference after the filtering process
+ is finished (after end_frame or filter_samples returns) must have the
+ PRESERVE permission on it and remove the WRITE permission if they
+ create a new reference to give it away.
+
+ * Filters that intend to modify a reference they have kept after the end
+ of the filtering process need the REUSE2 permission and must remove
+ the PRESERVE permission if they create a new reference to give it
+ away.
+
+
+Frame scheduling
+================
+
+ The purpose of these rules is to ensure that frames flow in the filter
+ graph without getting stuck and accumulating somewhere.
+
+ Simple filters that output one frame for each input frame should not have
+ to worry about it.
+
+ start_frame / filter_samples
+ ----------------------------
+
+ These methods are called when a frame is pushed to the filter's input.
+ They can be called at any time except in a reentrant way.
+
+ If the input frame is enough to produce output, then the filter should
+ push the output frames on the output link immediately.
+
+ As an exception to the previous rule, if the input frame is enough to
+ produce several output frames, then the filter needs output only at
+ least one per link. The additional frames can be left buffered in the
+ filter; these buffered frames must be flushed immediately if a new input
+ produces new output.
+
+ (Example: framerate-doubling filter: start_frame must (1) flush the
+ second copy of the previous frame, if it is still there, (2) push the
+ first copy of the incoming frame, (3) keep the second copy for later.)
+
+ If the input frame is not enough to produce output, the filter must not
+ call request_frame to get more. It must just process the frame or queue
+ it. The task of requesting more frames is left to the filter's
+ request_frame method or the application.
+
+ If a filter has several inputs, the filter must be ready for frames
+ arriving randomly on any input. Therefore, any filter with several inputs
+ will most likely require some kind of queuing mechanism. It is perfectly
+ acceptable to have a limited queue and to drop frames when the inputs
+ are too unbalanced.
+
+ request_frame
+ -------------
+
+ This method is called when a frame is wanted on an output.
+
+ For an input, it should directly call start_frame or filter_samples on
+ the corresponding output.
+
+ For a filter, if there are queued frames already ready, one of these
+ frames should be pushed. If not, the filter should request a frame on
+ one of its inputs, repeatedly until at least one frame has been pushed.
+
+ Return values:
+ if request_frame could produce a frame, it should return 0;
+ if it could not for temporary reasons, it should return AVERROR(EAGAIN);
+ if it could not because there are no more frames, it should return
+ AVERROR_EOF.
+
+ The typical implementation of request_frame for a filter with several
+ inputs will look like that:
+
+ if (frames_queued) {
+ push_one_frame();
+ return 0;
+ }
+ while (!frame_pushed) {
+ input = input_where_a_frame_is_most_needed();
+ ret = avfilter_request_frame(input);
+ if (ret == AVERROR_EOF) {
+ process_eof_on_input();
+ } else if (ret < 0) {
+ return ret;
+ }
+ }
+ return 0;
+
+ Note that, except for filters that can have queued frames, request_frame
+ does not push frames: it requests them to its input, and as a reaction,
+ the start_frame / filter_samples method will be called and do the work.

+@chapter Filtering Introduction
+@c man begin FILTERING INTRODUCTION
+
+Filtering in FFmpeg is enabled through the libavfilter library.
+
+Libavfilter is the filtering API of FFmpeg. It is the substitute of
+the now deprecated 'vhooks' and started as a Google Summer of Code
+project.
+
+Audio filtering integration into the main FFmpeg repository is a work in
+progress, so audio API and ABI should not be considered stable yet.
+
+In libavfilter, it is possible for filters to have multiple inputs and
+multiple outputs.
+To illustrate the sorts of things that are possible, we can
+use a complex filter graph. For example, the following one:
+
+@example
+input --> split --> fifo -----------------------> overlay --> output
+ | ^
+ | |
+ +------> fifo --> crop --> vflip --------+
+@end example
+
+splits the stream in two streams, sends one stream through the crop filter
+and the vflip filter before merging it back with the other stream by
+overlaying it on top. You can use the following command to achieve this:
+
+@example
+ffmpeg -i input -vf "[in] split [T1], fifo, [T2] overlay=0:H/2 [out]; [T1] fifo, crop=iw:ih/2:0:ih/2, vflip [T2]" output
+@end example
+
+The result will be that in output the top half of the video is mirrored
+onto the bottom half.
+
+Filters are loaded using the @var{-vf} or @var{-af} option passed to
+@command{ffmpeg} or to @command{ffplay}. Filters in the same linear
+chain are separated by commas. In our example, @var{split, fifo,
+overlay} are in one linear chain, and @var{fifo, crop, vflip} are in
+another. The points where the linear chains join are labeled by names
+enclosed in square brackets. In our example, that is @var{[T1]} and
+@var{[T2]}. The special labels @var{[in]} and @var{[out]} are the points
+where video is input and output.
+
+Some filters take in input a list of parameters: they are specified
+after the filter name and an equal sign, and are separated from each other
+by a colon.
+
+There exist so-called @var{source filters} that do not have an
+audio/video input, and @var{sink filters} that will not have audio/video
+output.

+If the channel layouts of the inputs are disjoint, and therefore compatible,

+For example, if the first input is in 2.1 (FL+FR+LF) and the second input
+is FC+BL+BR, then the output will be in 5.1, with the channels in the
+following order: a1, a2, b1, a3, b2, b3 (a1 is the first channel of the

+Example: stress-test @code{amerge} by randomly sending buffers on the wrong

+[a] [b] astreamsync=(2*random(1))-1+tanh(5*(t1-t2)) [a2] [b2] ;
+[a2] [b2] amerge
+@end example
+
+@section atempo
+
+Adjust audio tempo.
+
+The filter accepts exactly one parameter, the audio tempo. If not
+specified then the filter will assume nominal 1.0 tempo. Tempo must
+be in the [0.5, 2.0] range.
+
+For example, to slow down audio to 80% tempo:
+@example
+atempo=0.8
+@end example
+
+For example, to speed up audio to 125% tempo:
+@example
+atempo=1.25
+@end example
+
+@section earwax
+
+Make audio easier to listen to on headphones.
+
+This filter adds `cues' to 44.1kHz stereo (i.e. audio CD format) audio
+so that when listened to on headphones the stereo image is moved from
+inside your head (standard for headphones) to outside and in front of
+the listener (standard for speakers).
+
+Ported from SoX.
+
+@section pan
+
+Mix channels with specific gain levels. The filter accepts the output
+channel layout followed by a set of channels definitions.
+
+This filter is also designed to remap efficiently the channels of an audio
+stream.
+
+The filter accepts parameters of the form:
+"@var{l}:@var{outdef}:@var{outdef}:..."
+
+@table @option
+@item l
+output channel layout or number of channels
+
+@item outdef
+output channel specification, of the form:
+"@var{out_name}=[@var{gain}*]@var{in_name}[+[@var{gain}*]@var{in_name}...]"
+
+@item out_name
+output channel to define, either a channel name (FL, FR, etc.) or a channel
+number (c0, c1, etc.)
+
+@item gain
+multiplicative coefficient for the channel, 1 leaving the volume unchanged
+
+@item in_name
+input channel to use, see out_name for details; it is not possible to mix
+named and numbered input channels
+@end table
+
+If the `=' in a channel specification is replaced by `<', then the gains for
+that specification will be renormalized so that the total is 1, thus
+avoiding clipping noise.
+
+@subsection Mixing examples
+
+For example, if you want to down-mix from stereo to mono, but with a bigger
+factor for the left channel:
+@example
+pan=1:c0=0.9*c0+0.1*c1
+@end example
+
+A customized down-mix to stereo that works automatically for 3-, 4-, 5- and
+7-channels surround:
+@example
+pan=stereo: FL < FL + 0.5*FC + 0.6*BL + 0.6*SL : FR < FR + 0.5*FC + 0.6*BR + 0.6*SR
+@end example
+
+Note that @command{ffmpeg} integrates a default down-mix (and up-mix) system
+that should be preferred (see "-ac" option) unless you have very specific
+needs.
+
+@subsection Remapping examples
+
+The channel remapping will be effective if, and only if:
+
+@itemize
+@item gain coefficients are zeroes or ones,
+@item only one input per channel output,
+@end itemize
+
+If all these conditions are satisfied, the filter will notify the user ("Pure
+channel mapping detected"), and use an optimized and lossless method to do the
+remapping.
+
+For example, if you have a 5.1 source and want a stereo audio stream by
+dropping the extra channels:
+@example
+pan="stereo: c0=FL : c1=FR"
+@end example
+
+Given the same source, you can also switch front left and front right channels
+and keep the input channel layout:
+@example
+pan="5.1: c0=c1 : c1=c0 : c2=c2 : c3=c3 : c4=c4 : c5=c5"
+@end example
+
+If the input is a stereo audio stream, you can mute the front left channel (and
+still keep the stereo channel layout) with:
+@example
+pan="stereo:c1=c1"
+@end example
+
+Still with a stereo audio stream input, you can copy the right channel in both
+front left and right:
+@example
+pan="stereo: c0=FR : c1=FR"
+@end example
+
+@section silencedetect
+
+Detect silence in an audio stream.
+
+This filter logs a message when it detects that the input audio volume is less
+or equal to a noise tolerance value for a duration greater or equal to the
+minimum detected noise duration.
+
+The printed times and duration are expressed in seconds.
+
+@table @option
+@item duration, d
+Set silence duration until notification (default is 2 seconds).
+
+@item noise, n
+Set noise tolerance. Can be specified in dB (in case "dB" is appended to the
+specified value) or amplitude ratio. Default is -60dB, or 0.001.
+@end table
+
+Detect 5 seconds of silence with -50dB noise tolerance:
+@example
+silencedetect=n=-50dB:d=5
+@end example
+
+Complete example with @command{ffmpeg} to detect silence with 0.0001 noise
+tolerance in @file{silence.mp3}:
+@example
+ffmpeg -f lavfi -i amovie=silence.mp3,silencedetect=noise=0.0001 -f null -
+@end example
+
+@section volume
+
+Adjust the input audio volume.
+
+The filter accepts exactly one parameter @var{vol}, which expresses
+how the audio volume will be increased or decreased.
+
+Output values are clipped to the maximum value.
+
+If @var{vol} is expressed as a decimal number, the output audio
+volume is given by the relation:
+@example
+@var{output_volume} = @var{vol} * @var{input_volume}
+@end example
+
+If @var{vol} is expressed as a decimal number followed by the string
+"dB", the value represents the requested change in decibels of the
+input audio power, and the output audio volume is given by the
+relation:
+@example
+@var{output_volume} = 10^(@var{vol}/20) * @var{input_volume}
+@end example
+
+Otherwise @var{vol} is considered an expression and its evaluated
+value is used for computing the output audio volume according to the
+first relation.
+
+Default value for @var{vol} is 1.0.
+
+@subsection Examples
+
+@itemize
+@item
+Half the input audio volume:
+@example
+volume=0.5
+@end example
+
+The above example is equivalent to:
+@example
+volume=1/2
+@end example
+
+@item
+Decrease input audio power by 12 decibels:
+@example
+volume=-12dB
+@end example
+@end itemize
+
+@section volumedetect
+
+Detect the volume of the input video.
+
+The filter has no parameters. The input is not modified. Statistics about
+the volume will be printed in the log when the input stream end is reached.
+
+In particular it will show the mean volume (root mean square), maximum
+volume (on a per-sample basis), and the beginning of an histogram of the
+registered volume values (from the maximum value to a cumulated 1/1000 of
+the samples).
+
+All volumes are in decibels relative to the maximum PCM value.
+
+Here is an excerpt of the output:
+@example
+[Parsed_volumedetect_0 @ 0xa23120] mean_volume: -27 dB
+[Parsed_volumedetect_0 @ 0xa23120] max_volume: -4 dB
+[Parsed_volumedetect_0 @ 0xa23120] histogram_4db: 6
+[Parsed_volumedetect_0 @ 0xa23120] histogram_5db: 62
+[Parsed_volumedetect_0 @ 0xa23120] histogram_6db: 286
+[Parsed_volumedetect_0 @ 0xa23120] histogram_7db: 1042
+[Parsed_volumedetect_0 @ 0xa23120] histogram_8db: 2551
+[Parsed_volumedetect_0 @ 0xa23120] histogram_9db: 4609
+[Parsed_volumedetect_0 @ 0xa23120] histogram_10db: 8409
+@end example
+
+It means that:
+@itemize
+@item
+The mean square energy is approximately -27 dB, or 10^-2.7.
+@item
+The largest sample is at -4 dB, or more precisely between -4 dB and -5 dB.
+@item
+There are 6 samples at -4 dB, 62 at -5 dB, 286 at -6 dB, etc.
+@end itemize
+
+In other words, raising the volume by +4 dB does not cause any clipping,
+raising it by +5 dB causes clipping for 6 samples, etc.

+Extract the alpha component from the input as a grayscale video. This
+is especially useful with the @var{alphamerge} filter.
+
+@section alphamerge
+
+Add or replace the alpha component of the primary input with the
+grayscale value of a second input. This is intended for use with
+@var{alphaextract} to allow the transmission or storage of frame
+sequences that have alpha in a format that doesn't support an alpha
+channel.
+
+For example, to reconstruct full frames from a normal YUV-encoded video
+and a separate video created with @var{alphaextract}, you might use:
+@example
+movie=in_alpha.mkv [alpha]; [in][alpha] alphamerge [out]
+@end example
+
+Since this filter is designed for reconstruction, it operates on frame
+sequences without considering timestamps, and terminates when either
+input reaches end of stream. This will cause problems if your encoding
+pipeline drops frames. If you're trying to apply an image as an

+Apply an MPlayer filter to the input video.
+
+This filter provides a wrapper around most of the filters of
+MPlayer/MEncoder.
+
+This wrapper is considered experimental. Some of the wrapped filters
+may not work properly and we may drop support for them, as they will
+be implemented natively into FFmpeg. Thus you should avoid
+depending on them when writing portable scripts.
+
+The filters accepts the parameters:
+@var{filter_name}[:=]@var{filter_params}
+
+@var{filter_name} is the name of a supported MPlayer filter,
+@var{filter_params} is a string containing the parameters accepted by
+the named filter.

+
+This filter requires one argument which specifies the filter bitmap

+
+Pixels in the provided bitmap image with a value of zero are not

+If needed, little splotches can be fixed manually. Remember that if

+reduced. Marking too many pixels as part of the logo does not hurt as
+much, but it will increase the amount of blurring needed to cover over

+
+@section life
+
+Generate a life pattern.
+
+This source is based on a generalization of John Conway's life game.
+
+The sourced input represents a life grid, each pixel represents a cell
+which can be in one of two possible states, alive or dead. Every cell
+interacts with its eight neighbours, which are the cells that are
+horizontally, vertically, or diagonally adjacent.
+
+At each interaction the grid evolves according to the adopted rule,
+which specifies the number of neighbor alive cells which will make a
+cell stay alive or born. The @option{rule} option allows to specify
+the rule to adopt.
+
+This source accepts a list of options in the form of
+@var{key}=@var{value} pairs separated by ":". A description of the
+accepted options follows.
+
+@table @option
+@item filename, f
+Set the file from which to read the initial grid state. In the file,
+each non-whitespace character is considered an alive cell, and newline
+is used to delimit the end of each row.
+
+If this option is not specified, the initial grid is generated
+randomly.
+
+@item rate, r
+Set the video rate, that is the number of frames generated per second.
+Default is 25.
+
+@item random_fill_ratio, ratio
+Set the random fill ratio for the initial random grid. It is a
+floating point number value ranging from 0 to 1, defaults to 1/PHI.
+It is ignored when a file is specified.
+
+@item random_seed, seed
+Set the seed for filling the initial random grid, must be an integer
+included between 0 and UINT32_MAX. If not specified, or if explicitly
+set to -1, the filter will try to use a good random seed on a best
+effort basis.
+
+@item rule
+Set the life rule.
+
+A rule can be specified with a code of the kind "S@var{NS}/B@var{NB}",
+where @var{NS} and @var{NB} are sequences of numbers in the range 0-8,
+@var{NS} specifies the number of alive neighbor cells which make a
+live cell stay alive, and @var{NB} the number of alive neighbor cells
+which make a dead cell to become alive (i.e. to "born").
+"s" and "b" can be used in place of "S" and "B", respectively.
+
+Alternatively a rule can be specified by an 18-bits integer. The 9
+high order bits are used to encode the next cell state if it is alive
+for each number of neighbor alive cells, the low order bits specify
+the rule for "borning" new cells. Higher order bits encode for an
+higher number of neighbor cells.
+For example the number 6153 = @code{(12<<9)+9} specifies a stay alive
+rule of 12 and a born rule of 9, which corresponds to "S23/B03".
+
+Default value is "S23/B3", which is the original Conway's game of life
+rule, and will keep a cell alive if it has 2 or 3 neighbor alive
+cells, and will born a new cell if there are three alive cells around
+a dead cell.
+
+@item size, s
+Set the size of the output video.
+
+If @option{filename} is specified, the size is set by default to the
+same size of the input file. If @option{size} is set, it must contain
+the size specified in the input file, and the initial grid defined in
+that file is centered in the larger resulting area.
+
+If a filename is not specified, the size value defaults to "320x240"
+(used for a randomly generated initial grid).
+
+@item stitch
+If set to 1, stitch the left and right grid edges together, and the
+top and bottom edges also. Defaults to 1.
+
+@item mold
+Set cell mold speed. If set, a dead cell will go from @option{death_color} to
+@option{mold_color} with a step of @option{mold}. @option{mold} can have a
+value from 0 to 255.
+
+@item life_color
+Set the color of living (or new born) cells.
+
+@item death_color
+Set the color of dead cells. If @option{mold} is set, this is the first color
+used to represent a dead cell.
+
+@item mold_color
+Set mold color, for definitely dead and moldy cells.

+@end table
+
+@subsection Commands syntax
+
+A commands description consists of a sequence of interval
+specifications, comprising a list of commands to be executed when a
+particular event related to that interval occurs. The occurring event
+is typically the current frame time entering or leaving a given time
+interval.
+
+An interval is specified by the following syntax:
+@example
+@var{START}[-@var{END}] @var{COMMANDS};
+@end example
+
+The time interval is specified by the @var{START} and @var{END} times.
+@var{END} is optional and defaults to the maximum time.
+
+The current frame time is considered within the specified interval if
+it is included in the interval [@var{START}, @var{END}), that is when
+the time is greater or equal to @var{START} and is lesser than
+@var{END}.
+
+@var{COMMANDS} consists of a sequence of one or more command
+specifications, separated by ",", relating to that interval. The
+syntax of a command specification is given by:
+@example
+[@var{FLAGS}] @var{TARGET} @var{COMMAND} @var{ARG}
+@end example
+
+@var{FLAGS} is optional and specifies the type of events relating to
+the time interval which enable sending the specified command, and must
+be a non-null sequence of identifier flags separated by "+" or "|" and
+enclosed between "[" and "]".
+
+The following flags are recognized:
+@table @option
+@item enter

+@section ebur128
+
+EBU R128 scanner filter. This filter takes an audio stream as input and outputs
+it unchanged. By default, it logs a message at a frequency of 10Hz with the
+Momentary loudness (identified by @code{M}), Short-term loudness (@code{S}),
+Integrated loudness (@code{I}) and Loudness Range (@code{LRA}).
+
+The filter also has a video output (see the @var{video} option) with a real
+time graph to observe the loudness evolution. The graphic contains the logged
+message mentioned above, so it is not printed anymore when this option is set,
+unless the verbose logging is set. The main graphing area contains the
+short-term loudness (3 seconds of analysis), and the gauge on the right is for
+the momentary loudness (400 milliseconds).
+
+More information about the Loudness Recommendation EBU R128 on
+@url{http://tech.ebu.ch/loudness}.
+
+The filter accepts the following named parameters:
+
+@table @option
+
+@item video
+Activate the video output. The audio stream is passed unchanged whether this
+option is set or no. The video stream will be the first output stream if
+activated. Default is @code{0}.
+
+@item size
+Set the video size. This option is for video only. Default and minimum
+resolution is @code{640x480}.
+
+@item meter
+Set the EBU scale meter. Default is @code{9}. Common values are @code{9} and
+@code{18}, respectively for EBU scale meter +9 and EBU scale meter +18. Any
+other integer value between this range is allowed.
+
+@end table

+Example of real-time graph using @command{ffplay}, with a EBU scale meter +18:

+@end example
+
+Run an analysis with @command{ffmpeg}:
+@example
+ffmpeg -nostats -i input.mp3 -filter_complex ebur128 -f null -
+@end example
+
+@section settb, asettb
+
+Set the timebase to use for the output frames timestamps.
+It is mainly useful for testing timebase configuration.
+
+It accepts in input an arithmetic expression representing a rational.
+The expression can contain the constants "AVTB" (the
+default timebase), "intb" (the input timebase) and "sr" (the sample rate,
+audio only).
+
+The default value for the input is "intb".
+
+@subsection Examples
+
+@itemize
+@item
+Set the timebase to 1/25:
+@example
+settb=1/25
+@end example
+
+@item
+Set the timebase to 1/10:
+@example

+settb=AVTB
+@end example
+@end itemize
+
+@section concat
+
+Concatenate audio and video streams, joining them together one after the
+other.
+
+The filter works on segments of synchronized video and audio streams. All
+segments must have the same number of streams of each type, and that will
+also be the number of streams at output.
+
+The filter accepts the following named parameters:
+@table @option
+
+@item n
+Set the number of segments. Default is 2.
+
+@item v
+Set the number of output video streams, that is also the number of video
+streams in each segment. Default is 1.
+
+@item a
+Set the number of output audio streams, that is also the number of video
+streams in each segment. Default is 0.
+
+@end table
+
+The filter has @var{v}+@var{a} outputs: first @var{v} video outputs, then
+@var{a} audio outputs.
+
+There are @var{n}×(@var{v}+@var{a}) inputs: first the inputs for the first
+segment, in the same order as the outputs, then the inputs for the second
+segment, etc.
+
+Related streams do not always have exactly the same duration, for various
+reasons including codec frame size or sloppy authoring. For that reason,
+related synchronized streams (e.g. a video and its audio track) should be
+concatenated at once. The concat filter will use the duration of the longest
+stream in each segment (except the last one), and if necessary pad shorter
+audio streams with silence.
+
+For this filter to work correctly, all segments must start at timestamp 0.
+
+All corresponding streams must have the same parameters in all segments; the
+filtering system will automatically select a common pixel format for video
+streams, and a common sample format, sample rate and channel layout for
+audio streams, but other settings, such as resolution, must be converted
+explicitly by the user.
+
+Different frame rates are acceptable but will result in variable frame rate
+at output; be sure to configure the output file to handle it.
+
+Examples:
+@itemize
+@item
+Concatenate an opening, an episode and an ending, all in bilingual version
+(video in stream 0, audio in streams 1 and 2):
+@example
+ffmpeg -i opening.mkv -i episode.mkv -i ending.mkv -filter_complex \
+ '[0:0] [0:1] [0:2] [1:0] [1:1] [1:2] [2:0] [2:1] [2:2]
+ concat=n=3:v=1:a=2 [v] [a1] [a2]' \
+ -map '[v]' -map '[a1]' -map '[a2]' output.mkv
+@end example
+
+@item
+Concatenate two parts, handling audio and video separately, using the
+(a)movie sources, and adjusting the resolution:
+@example
+movie=part1.mp4, scale=512:288 [v1] ; amovie=part1.mp4 [a1] ;
+movie=part2.mp4, scale=512:288 [v2] ; amovie=part2.mp4 [a2] ;
+[v1] [v2] concat [outv] ; [a1] [a2] concat=v=0:a=1 [outa]
+@end example
+Note that a desync will happen at the stitch if the audio and video streams
+do not have exactly the same duration in the first file.

+@section showspectrum
+
+Convert input audio to a video output, representing the audio frequency
+spectrum.
+
+The filter accepts the following named parameters:
+@table @option
+@item size, s
+Specify the video size for the output. Default value is @code{640x480}.
+@end table
+
+The usage is very similar to the showwaves filter; see the examples in that
+section.
+
+@section showwaves
+
+Convert input audio to a video output, representing the samples waves.
+
+The filter accepts the following named parameters:
+@table @option
+
+@item n
+Set the number of samples which are printed on the same column. A
+larger value will decrease the frame rate. Must be a positive
+integer. This option can be set only if the value for @var{rate}
+is not explicitly specified.
+
+@item rate, r
+Set the (approximate) output frame rate. This is done by setting the
+option @var{n}. Default value is "25".
+
+@item size, s
+Specify the video size for the output. Default value is "600x240".
+@end table

+@section openal
+
+The OpenAL input device provides audio capture on all systems with a
+working OpenAL 1.1 implementation.
+
+To enable this input device during configuration, you need OpenAL
+headers and libraries installed on your system, and need to configure
+FFmpeg with @code{--enable-openal}.
+
+OpenAL headers and libraries should be provided as part of your OpenAL
+implementation, or as an additional download (an SDK). Depending on your
+installation you may need to specify additional flags via the
+@code{--extra-cflags} and @code{--extra-ldflags} for allowing the build
+system to locate the OpenAL headers and libraries.
+
+An incomplete list of OpenAL implementations follows:
+

+FFmpeg's bug/patch/feature request tracker manual
+=================================================
+
+NOTE: This is a draft.
+
+Overview:
+---------
+
+FFmpeg uses Trac for tracking issues, new issues and changes to
+existing issues can be done through a web interface.
+
+Issues can be different kinds of things we want to keep track of
+but that do not belong into the source tree itself. This includes
+bug reports, patches, feature requests and license violations. We
+might add more items to this list in the future, so feel free to
+propose a new `type of issue' on the ffmpeg-devel mailing list if
+you feel it is worth tracking.
+
+It is possible to subscribe to individual issues by adding yourself to the
+Cc list or to subscribe to the ffmpeg-trac mailing list which receives
+a mail for every change to every issue.
+(the above does all work already after light testing)
+
+The subscription URL for the ffmpeg-trac list is:
+http(s)://ffmpeg.org/mailman/listinfo/ffmpeg-trac
+The URL of the webinterface of the tracker is:
+http(s)://ffmpeg.org/trac/ffmpeg
+
+Type:
+-----
+bug / defect
+ An error, flaw, mistake, failure, or fault in FFmpeg or libav* that
+ prevents it from behaving as intended.
+
+feature request / enhancement
+ Request of support for encoding or decoding of a new codec, container
+ or variant.
+ Request of support for more, less or plain different output or behavior
+ where the current implementation cannot be considered wrong.
+
+license violation
+ ticket to keep track of (L)GPL violations of ffmpeg by others
+
+patch
+ A patch as generated by diff which conforms to the patch submission and
+ development policy.
+
+
+Priority:
+---------
+critical
+ Bugs and patches which deal with data loss and security issues.
+ No feature request can be critical.
+
+important
+ Bugs which make FFmpeg unusable for a significant number of users, and
+ patches fixing them.
+ Examples here might be completely broken MPEG-4 decoding or a build issue
+ on Linux.
+ While broken 4xm decoding or a broken OS/2 build would not be important,
+ the separation to normal is somewhat fuzzy.
+ For feature requests this priority would be used for things many people
+ want.
+ Regressions also should be marked as important, regressions are bugs that
+ don't exist in a past revision or another branch.
+
+normal
+
+
+minor
+ Bugs and patches about things like spelling errors, "mp2" instead of
+ "mp3" being shown and such.
+ Feature requests about things few people want or which do not make a big
+ difference.
+
+wish
+ Something that is desirable to have but that there is no urgency at
+ all to implement, e.g. something completely cosmetic like a website
+ restyle or a personalized doxy template or the FFmpeg logo.
+ This priority is not valid for bugs.

-@chapter Introduction
-
-Libavfilter is the filtering API of Libav. It is the substitute of the
-now deprecated 'vhooks' and started as a Google Summer of Code project.
-
-But note that there may still be serious bugs in the code and its API
-and ABI should not be considered stable yet!
-
-@chapter Tutorial
-
-In libavfilter, it is possible for filters to have multiple inputs and
-multiple outputs.
-To illustrate the sorts of things that are possible, we can
-use a complex filter graph. For example, the following one:
-
-@example
-input --> split --> fifo -----------------------> overlay --> output
- | ^
- | |
- +------> fifo --> crop --> vflip --------+
-@end example
-
-splits the stream in two streams, sends one stream through the crop filter
-and the vflip filter before merging it back with the other stream by
-overlaying it on top. You can use the following command to achieve this:
-
-@example
-./avconv -i input -vf "[in] split [T1], fifo, [T2] overlay=0:H/2 [out]; [T1] fifo, crop=iw:ih/2:0:ih/2, vflip [T2]" output
-@end example
-
-The result will be that in output the top half of the video is mirrored
-onto the bottom half.
-
-Video filters are loaded using the @var{-vf} option passed to
-avconv or to avplay. Filters in the same linear chain are separated by
-commas. In our example, @var{split, fifo, overlay} are in one linear
-chain, and @var{fifo, crop, vflip} are in another. The points where
-the linear chains join are labeled by names enclosed in square
-brackets. In our example, that is @var{[T1]} and @var{[T2]}. The magic
-labels @var{[in]} and @var{[out]} are the points where video is input
-and output.
-
-Some filters take in input a list of parameters: they are specified
-after the filter name and an equal sign, and are separated each other
-by a semicolon.
-
-There exist so-called @var{source filters} that do not have a video
-input, and we expect in the future some @var{sink filters} that will
-not have video output.
-
-@chapter graph2dot
-
-The @file{graph2dot} program included in the Libav @file{tools}
-directory can be used to parse a filter graph description and issue a
-corresponding textual representation in the dot language.
-
-Invoke the command:
-@example
-graph2dot -h
-@end example
-
-to see how to use @file{graph2dot}.
-
-You can then pass the dot description to the @file{dot} program (from
-the graphviz suite of programs) and obtain a graphical representation
-of the filter graph.
-
-For example the sequence of commands:
-@example
-echo @var{GRAPH_DESCRIPTION} | \
-tools/graph2dot -o graph.tmp && \
-dot -Tpng graph.tmp -o graph.png && \
-display graph.png
-@end example
-
-can be used to create and display an image representing the graph
-described by the @var{GRAPH_DESCRIPTION} string.

+Either Resampling and Rematrixing can be performed first depending on which

+The Buffers are needed for resampling due to resamplng being a process that
+requires future and past data, it thus also introduces inevitably a delay when
+used.
+Internally 32bit float and 16bit int is supported currently, other formats can
+easily be added.
+Externally all sample formats in packed and planar configuration are supported
+It's also trivial to add special converters for common cases.
+If only sample format and/or packed/planar conversion is needed, it
+is performed from input to output directly in a single pass with no intermediates.

+@chapter Syntax
+@c man begin SYNTAX
+
+When evaluating specific formats, FFmpeg uses internal library parsing
+functions, shared by the tools. This section documents the syntax of
+some of these formats.
+
+@anchor{date syntax}
+@section Date
+
+The accepted syntax is:
+@example
+[(YYYY-MM-DD|YYYYMMDD)[T|t| ]]((HH:MM:SS[.m...]]])|(HHMMSS[.m...]]]))[Z]
+now
+@end example
+
+If the value is "now" it takes the current time.
+
+Time is local time unless Z is appended, in which case it is
+interpreted as UTC.
+If the year-month-day part is not specified it takes the current
+year-month-day.
+
+@anchor{time duration syntax}
+@section Time duration
+
+The accepted syntax is:
+@example
+[-]HH:MM:SS[.m...]
+[-]S+[.m...]
+@end example
+
+@var{HH} expresses the number of hours, @var{MM} the number a of minutes
+and @var{SS} the number of seconds.
+
+@anchor{video size syntax}
+@section Video size
+Specify the size of the sourced video, it may be a string of the form
+@var{width}x@var{height}, or the name of a size abbreviation.
+
+The following abbreviations are recognized:
+@table @samp
+@item sqcif
+128x96
+@item qcif
+176x144
+@item cif
+352x288
+@item 4cif

+1280x720
+@item hd1080
+1920x1080
+@end table
+
+@anchor{video rate syntax}
+@section Video rate
+
+Specify the frame rate of a video, expressed as the number of frames
+generated per second. It has to be a string in the format
+@var{frame_rate_num}/@var{frame_rate_den}, an integer number, a float
+number or a valid video frame rate abbreviation.
+
+The following abbreviations are recognized:
+@table @samp
+@item ntsc
+30000/1001
+@item pal
+25/1
+@item qntsc
+30000/1
+@item qpal
+25/1
+@item sntsc
+30000/1
+@item spal
+25/1
+@item film
+24/1
+@item ntsc-film
+24000/1
+@end table
+
+@anchor{ratio syntax}
+@section Ratio
+
+A ratio can be expressed as an expression, or in the form
+@var{numerator}:@var{denominator}.
+
+Note that a ratio with infinite (1/0) or negative value is
+considered valid, so you should check on the returned value if you
+want to exclude those values.
+
+The undefined value can be expressed using the "0:0" string.
+
+@anchor{color syntax}
+@section Color
+
+It can be the name of a color (case insensitive match) or a
+[0x|#]RRGGBB[AA] sequence, possibly followed by "@@" and a string
+representing the alpha component.
+
+The alpha component may be a string composed by "0x" followed by an
+hexadecimal number or a decimal number between 0.0 and 1.0, which
+represents the opacity value (0x00/0.0 means completely transparent,
+0xff/1.0 completely opaque).
+If the alpha component is not specified then 0xff is assumed.
+
+The string "random" will result in a random color.

+
+/*
+ * - Principles of Operation -
+ *
+ * The CrystalHD decoder operates at the bitstream level - which is an even
+ * higher level than the decoding hardware you typically see in modern GPUs.
+ * This means it has a very simple interface, in principle. You feed demuxed
+ * packets in one end and get decoded picture (fields/frames) out the other.
+ *
+ * Of course, nothing is ever that simple. Due, at the very least, to b-frame
+ * dependencies in the supported formats, the hardware has a delay between
+ * when a packet goes in, and when a picture comes out. Furthermore, this delay
+ * is not just a function of time, but also one of the dependency on additional
+ * frames being fed into the decoder to satisfy the b-frame dependencies.
+ *
+ * As such, a pipeline will build up that is roughly equivalent to the required
+ * DPB for the file being played. If that was all it took, things would still
+ * be simple - so, of course, it isn't.
+ *
+ * The hardware has a way of indicating that a picture is ready to be copied out,
+ * but this is unreliable - and sometimes the attempt will still fail so, based
+ * on testing, the code will wait until 3 pictures are ready before starting
+ * to copy out - and this has the effect of extending the pipeline.
+ *
+ * Finally, while it is tempting to say that once the decoder starts outputting
+ * frames, the software should never fail to return a frame from a decode(),
+ * this is a hard assertion to make, because the stream may switch between
+ * differently encoded content (number of b-frames, interlacing, etc) which
+ * might require a longer pipeline than before. If that happened, you could
+ * deadlock trying to retrieve a frame that can't be decoded without feeding
+ * in additional packets.
+ *
+ * As such, the code will return in the event that a picture cannot be copied
+ * out, leading to an increase in the length of the pipeline. This in turn,
+ * means we have to be sensitive to the time it takes to decode a picture;
+ * We do not want to give up just because the hardware needed a little more
+ * time to prepare the picture! For this reason, there are delays included
+ * in the decode() path that ensure that, under normal conditions, the hardware
+ * will only fail to return a frame if it really needs additional packets to
+ * complete the decoding.
+ *
+ * Finally, to be explicit, we do not want the pipeline to grow without bound
+ * for two reasons: 1) The hardware can only buffer a finite number of packets,
+ * and 2) The client application may not be able to cope with arbitrarily long
+ * delays in the video path relative to the audio path. For example. MPlayer
+ * can only handle a 20 picture delay (although this is arbitrary, and needs
+ * to be extended to fully support the CrystalHD where the delay could be up
+ * to 32 pictures - consider PAFF H.264 content with 16 b-frames).

+ * https://sourceforge.net/projects/apprenticevideo/
+ *
+ * An explanation of SOLA algorithm is available at
+ * http://www.surina.net/article/time-and-pitch-scaling.html
+ *
+ * WSOLA is very similar to SOLA, only one major difference exists between
+ * these algorithms. SOLA shifts audio fragments along the output stream,
+ * where as WSOLA shifts audio fragments along the input stream.
+ *
+ * The advantage of WSOLA algorithm is that the overlap region size is
+ * always the same, therefore the blending function is constant and
+ * can be precomputed.

+"\n"\
+"These are continually updated to coincide with the latest developments that\n"\
+"occur and as a result should provide you with nearly the best quality\n"\
+"currently possible from LAME.\n"\
+"\n"\
+"To activate these presets:\n"\
+"\n"\
+" For VBR modes (generally highest quality):\n"\
+"\n"\
+" \"preset=standard\" This preset should generally be transparent\n"\
+" to most people on most music and is already\n"\
+" quite high in quality.\n"\
+"\n"\
+" \"preset=extreme\" If you have extremely good hearing and similar\n"\
+" equipment, this preset will generally provide\n"\
+" slightly higher quality than the \"standard\"\n"\
+" mode.\n"\
+"\n"\
+" For CBR 320kbps (highest quality possible from the preset switches):\n"\
+"\n"\
+" \"preset=insane\" This preset will usually be overkill for most\n"\
+" people and most situations, but if you must\n"\
+" have the absolute highest quality with no\n"\
+" regard to filesize, this is the way to go.\n"\
+"\n"\
+" For ABR modes (high quality per given bitrate but not as high as VBR):\n"\
+"\n"\
+" \"preset=<kbps>\" Using this preset will usually give you good\n"\
+" quality at a specified bitrate. Depending on the\n"\
+" bitrate entered, this preset will determine the\n"\
+" optimal settings for that particular situation.\n"\
+" While this approach works, it is not nearly as\n"\
+" flexible as VBR, and usually will not attain the\n"\
+" same level of quality as VBR at higher bitrates.\n"\
+"\n"\
+"The following options are also available for the corresponding profiles:\n"\

+" <fast> standard\n"\

+" <cbr> (ABR Mode) - The ABR Mode is implied. To use it,\n"\
+" simply specify a bitrate. For example:\n"\
+" \"preset=185\" activates this\n"\
+" preset and uses 185 as an average kbps.\n"\
+"\n"\
+" \"fast\" - Enables the new fast VBR for a particular profile. The\n"\
+" disadvantage to the speed switch is that often times the\n"\
+" bitrate will be slightly higher than with the normal mode\n"\
+" and quality may be slightly lower also.\n"\
+" Warning: with the current version fast presets might result in too\n"\
+" high bitrate compared to regular presets.\n"\
+"\n"\
+" \"cbr\" - If you use the ABR mode (read above) with a significant\n"\
+" bitrate such as 80, 96, 112, 128, 160, 192, 224, 256, 320,\n"\
+" you can use the \"cbr\" option to force CBR mode encoding\n"\
+" instead of the standard abr mode. ABR does provide higher\n"\

+Known Issues:
+* The motion estimation is somewhat at the mercy of the input, if the input
+ frames are created purely based on spatial interpolation then for example
+ a thin black line or another random and not interpolateable pattern
+ will cause problems
+ Note: completly ignoring the "unavailable" lines during motion estimation
+ didnt look any better, so the most obvious solution would be to improve
+ tfields or penalize problematic motion vectors ...
+
+* If non iterative ME is used then snow currently ignores the OBMC window
+ and as a result sometimes creates artifacts
+
+* only past frames are used, we should ideally use future frames too, something
+ like filtering the whole movie in forward and then backward direction seems
+ like a interresting idea but the current filter framework is FAR from
+ supporting such things
+
+* combining the motion compensated image with the input image also isnt
+ as trivial as it seems, simple blindly taking even lines from one and
+ odd ones from the other doesnt work at all as ME/MC sometimes simple
+ has nothing in the previous frames which matches the current, the current
+ algo has been found by trial and error and almost certainly can be
+ improved ...

+ * filter to tile a series of images in a single, bigger, image
+ *
+ * The parameters are:
+ *
+ * xtile: number of tiles on the x axis (5)
+ * ytile: number of tiles on the y axis (5)
+ * xytile: when writing the image, it can be different than xtile * ytile
+ * (for example you can write 8 * 7 tiles, writing the file every
+ * 50 frames, to have one image every 2 seconds @ 25 fps ).
+ * start: pixels at the start (x/y), default 2
+ * delta: pixels between 2 tiles, (x/y), default 4
+ *
+ * For example a valid command line is:
+ * ... -vf tile=10:5:-1:4:8 ...
+ * that makes images of 10 * 5 tiles, with 4 pixels at the beginning and
+ * 8 pixels between tiles.
+ *
+ * The default command is:
+ * ... -vf tile=5:5:25:2:4
+ *
+ * If you omit a parameter or put a value less than 0, the default is used.
+ * ... -vf tile=10:5::-1:10
+ *
+ * You can also stop when you're ok
+ * ... -vf tile=10:5
+ * (and this is probably the option you will use more often ...)
+ *
+ * Probably is good to put the scale filter before the tile :-)

+ * SAD block-matching motion compensation to fix small changes in

+ * from hand-holding a camera, bumping a tripod, moving on a vehicle, etc.
+ *
+ * Algorithm:
+ * - For each frame with one previous reference frame
+ * - For each block in the frame
+ * - If contrast > threshold then find likely motion vector
+ * - For all found motion vectors
+ * - Find most common, store as global motion vector
+ * - Find most likely rotation angle
+ * - Transform image along global motion
+ *
+ * TODO:
+ * - Fill frame edges based on previous/next reference frames
+ * - Fill frame edges by stretching image near the edges?
+ * - Can this be done quickly and look decent?
+ *
+ * Dark Shikari links to http://wiki.videolan.org/SoC_x264_2010#GPU_Motion_Estimation_2
+ * for an algorithm similar to what could be used here to get the gmv
+ * It requires only a couple diamond searches + fast downscaling

+/**
+ * @file
+ * Advanced blur-based logo removing filter
+ *
+ * This filter loads an image mask file showing where a logo is and
+ * uses a blur transform to remove the logo.
+ *
+ * Based on the libmpcodecs remove-logo filter by Robert Edele.
+ */
+
+/**
+ * This code implements a filter to remove annoying TV logos and other annoying
+ * images placed onto a video stream. It works by filling in the pixels that
+ * comprise the logo with neighboring pixels. The transform is very loosely
+ * based on a gaussian blur, but it is different enough to merit its own
+ * paragraph later on. It is a major improvement on the old delogo filter as it
+ * both uses a better blurring algorithm and uses a bitmap to use an arbitrary
+ * and generally much tighter fitting shape than a rectangle.
+ *
+ * The logo removal algorithm has two key points. The first is that it
+ * distinguishes between pixels in the logo and those not in the logo by using
+ * the passed-in bitmap. Pixels not in the logo are copied over directly without
+ * being modified and they also serve as source pixels for the logo
+ * fill-in. Pixels inside the logo have the mask applied.
+ *
+ * At init-time the bitmap is reprocessed internally, and the distance to the
+ * nearest edge of the logo (Manhattan distance), along with a little extra to
+ * remove rough edges, is stored in each pixel. This is done using an in-place
+ * erosion algorithm, and incrementing each pixel that survives any given
+ * erosion. Once every pixel is eroded, the maximum value is recorded, and a
+ * set of masks from size 0 to this size are generaged. The masks are circular
+ * binary masks, where each pixel within a radius N (where N is the size of the
+ * mask) is a 1, and all other pixels are a 0. Although a gaussian mask would be
+ * more mathematically accurate, a binary mask works better in practice because
+ * we generally do not use the central pixels in the mask (because they are in
+ * the logo region), and thus a gaussian mask will cause too little blur and
+ * thus a very unstable image.
+ *
+ * The mask is applied in a special way. Namely, only pixels in the mask that
+ * line up to pixels outside the logo are used. The dynamic mask size means that
+ * the mask is just big enough so that the edges touch pixels outside the logo,
+ * so the blurring is kept to a minimum and at least the first boundary
+ * condition is met (that the image function itself is continuous), even if the
+ * second boundary condition (that the derivative of the image function is
+ * continuous) is not met. A masking algorithm that does preserve the second
+ * boundary coundition (perhaps something based on a highly-modified bi-cubic
+ * algorithm) should offer even better results on paper, but the noise in a
+ * typical TV signal should make anything based on derivatives hopelessly noisy.

+ * Buffer to print data progressively
+ *
+ * The string buffer grows as necessary and is always 0-terminated.
+ * The content of the string is never accessed, and thus is
+ * encoding-agnostic and can even hold binary data.
+ *
+ * Small buffers are kept in the structure itself, and thus require no
+ * memory allocation at all (unless the contents of the buffer is needed
+ * after the structure goes out of scope). This is almost as lightweight as
+ * declaring a local "char buf[512]".
+ *
+ * The length of the string can go beyond the allocated size: the buffer is
+ * then truncated, but the functions still keep account of the actual total
+ * length.
+ *
+ * In other words, buf->len can be greater than buf->size and records the
+ * total length of what would have been to the buffer if there had been
+ * enough memory.
+ *
+ * Append operations do not need to be tested for failure: if a memory
+ * allocation fails, data stop being appended to the buffer, but the length
+ * is still updated. This situation can be tested with
+ * av_bprint_is_complete().
+ *
+ * The size_max field determines several possible behaviours:
+ *
+ * size_max = -1 (= UINT_MAX) or any large value will let the buffer be
+ * reallocated as necessary, with an amortized linear cost.
+ *
+ * size_max = 0 prevents writing anything to the buffer: only the total
+ * length is computed. The write operations can then possibly be repeated in
+ * a buffer with exactly the necessary size
+ * (using size_init = size_max = len + 1).
+ *
+ * size_max = 1 is automatically replaced by the exact size available in the
+ * structure itself, thus ensuring no dynamic memory allocation. The
+ * internal buffer is large enough to hold a reasonable paragraph of text,

+=head1 NAME
+
+make_chlayout_test - produce a multichannel test file with the channels
+clearly identified
+
+=head1 SYNOPSIS
+
+tools/make_chlayout_test I<channels> I<out_options>
+
+=head1 DESCRIPTION
+
+This script uses B<ffmpeg> and B<libflite> to produce a file with audio
+channels clearly identified by their name. The resulting file can be used to
+check that the layout and order of channels is correctly handled by a piece
+of software, either a part of B<FFmpeg> or not.
+
+I<channels> is a list of channels or channel layouts, separated by '+'.
+
+I<out_options> is a list of valid ffmpeg outout options, including the
+output file.
+
+Note that some output codecs or formats can not handle arbitrary channel
+layout.
+
+This script requires a B<ffmpeg> binary, either in the source tree or in the
+search path; it must have the flite audio source enabled.
+
+=head1 EXAMPLES
+
+Check that the speakers are correctly plugged:
+
+ tools/make_chlayout_test FL+FR -f alsa default
+
+Produce a 5.1 FLAC file:
+
+ tools/make_chlayout_test 5.1 surround.flac
