A single-segment hls media playlist which plays 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
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
Samples of assorted playlist types and a README file explaining how each sample is generated.
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.

Single MJPEG encoded frame of 1280x720, captured on Chromebook Pixel. This image does not have Huffman table.
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
A version of pixel-1280x720.jpg converted to grayscale using:
jpegtran -grayscale pixel-1280x720.jpg > pixel-1280x720-grayscale.jpg
Then, using a hex editor, the Huffman table sections were removed from the resulting file.
A version of pixel-1280x720.jpg converted to 4:2:0 subsampling using:
convert pixel-1280x720.jpg -sampling-factor 4:2:0 -define jpeg:optimize-coding=false pixel-1280x720-yuv420.jpg
Then, using a hex editor, the Huffman table sections were removed from the resulting file.
A version of pixel-1280x720-yuv420.jpg resized to 40x23 (so that the height is odd) using:
convert pixel-1280x720-yuv420.jpg -resize 40x23\! -define jpeg:optimize-coding=false pixel-40x23-yuv420.jpg
Then, using a hex editor, the Huffman table sections were removed from the resulting file.
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.
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.
A version of pixel-1280x720.jpg converted to 4:4:4 subsampling using:
convert pixel-1280x720.jpg -sampling-factor 4:4:4 -define jpeg:optimize-coding=false pixel-1280x720-yuv444.jpg
Then, using a hex editor, the Huffman table sections were removed from the resulting file.
