It‘s 1 keyframe + 1 non-keyframe, with container’s frame keyframe-ness correct.

bear-640x360-v-2frames-keyframe-is-non-sync-sample_frag.mp4

This is bear-640x360-v-2frames_frag.mp4, with manually updated trun.first_sample_flags: s/0x02000000/0x01010000 (first frame is non-sync-sample, depends on another frame, mismatches compressed h264 first frame's keyframe-ness).

bear-640x360-v-2frames-nonkeyframe-is-sync-sample_frag.mp4

This is bear-640x360-v-2frames_frag.mp4, with manually updated tfhd.default_sample_flags: s/0x01010000/0x02000000 (second frame is sync-sample, doesn‘t depend on other frames, mismatches compressed h264 second frame’s nonkeyframe-ness).

Encryption Scheme Test

  • bear-640x360-v_frag-cbcs.mp4
  • bear-640x360-v_frag-cens.mp4

Encrypted versions of bear-640x360-v_frag.mp4, encrypted by Shaka Packager v2.0.0 using key ID [1] and key [2]. Sample encryption information stored in SampleEncryption (‘senc’) box (in each encrypted fragment).

Command: (replace both places of ‘cenc’ with desired scheme)

The ‘pssh’ data includes entries for both Widevine and Common SystemID. It was generated from concatenating the output of:

HLS

bear-1280x720-hls.ts

Produced using Apple's mediafilesegmenter tool with bear-1280x720.ts as input, with no encryption.

mediafilesegmenter -t 10 -start-segments-with-iframe -f 'output_clear/' bear-1280x720.ts

bear-1280x720-hls-sample-aes.ts

Produced using Apple's mediafilesegmenter tool also with bear-1280x720.ts as input, but with SAMPLE_AES encryption. (Additional TS packets were constructed manually and prepended to convey the encryption metadata, notably key id and IV).

mediafilesegmenter -S -P -k 'key_iv.bin' -t 10 -start-segments-with-iframe -f 'output/' bear-1280x720.ts

bear-1280x720-hls-with-CAT.ts

Same as bear-1280x720-hls.ts but with an extra TS packet prepended. This is the same as the first of the metadata packets in bear-1280x720-hls-sample-aes.ts. Its presence indicates that SAMPLE_AES encryption may occur later in the stream, and causes the initial audio and video configs to have an encryption_scheme (of AES-CBC). The actual data is unencrypted, which is indicated by the lack of key ID and IV. This ends up very similar to how clear leader of an otherwise encrypted stream can occur in MP4.

pixel-1280x720-trailing-zeros.jpg

A version of pixel-1280x720.jpg with five trailing zero bytes after the EOI marker. The command used to generated it was:

echo -e "`xxd -g1 -p -c1 pixel-1280x720.jpg`" "\n00\n00\n00\n00\n00" | xxd -r -g1 -p -c1 > pixel-1280x720-trailing-zeros.jpg

Then, using a hex editor, the Huffman table sections were removed from the resulting file.

pixel-41x22-yuv420.jpg

A version of pixel-1280x720-yuv420.jpg resized to 41x22 (so that the width is odd) using:

convert pixel-1280x720-yuv420.jpg -resize 41x22\! -define jpeg:optimize-coding=false pixel-41x22-yuv420.jpg

Then, using a hex editor, the Huffman table sections were removed from the resulting file.

pixel-41x23-yuv420.jpg

A version of pixel-1280x720-yuv420.jpg resized to 41x23 (so that both dimensions are odd) using:

convert pixel-1280x720-yuv420.jpg -resize 41x23\! -define jpeg:optimize-coding=false pixel-41x23-yuv420.jpg

Then, using a hex editor, the Huffman table sections were removed from the resulting file.

pixel-1280x720-yuv444.jpg

    wget http://distribution.bbb3d.renderfarming.net/video/mp4/bbb_sunflower_1080p_30fps_normal.mp4
    
  2. Generate a scaled down to 320x240 video + 2 channel AAC LC audio from the source file.
    ffmpeg -i bbb_sunflower_1080p_30fps_normal.mp4 -c:v libx264 -crf 36 -vf  scale=320:240 -c:a libfdk_aac -ac 2 -t 24 bbb1.mp4
    
  3. Generate a file with the original video scaled down to 320x240 and flipped upside down and sine wave instead of audio.
    ffmpeg -i bbb_sunflower_1080p_30fps_normal.mp4 -f lavfi -i "sine=frequency=500:sample_rate=48000" -map 0:v -map 1:a -c:v libx264 -crf 36 -vf scale=320:240,vflip -c:a libfdk_aac -ac 2 -t 24 bbb2.mp4
    
  4. Combine the two files generated above into a single fragmented .mp4 file with 2 video and 2 audio tracks.
    ffmpeg -i bbb1.mp4 -i bbb2.mp4 -map 0:0 -map 0:1 -map 1:0 -map 1:1 -c:v copy -c:a copy -movflags frag_keyframe+omit_tfhd_offset+separate_moof bbb-320x240-2video-2audio.mp4
