bear-320x240.webm - WebM encode of bear.1280x720.mp4 resized to 320x240.
bear-320x240-vp9-opus.webm - Same as above, but with vp9 and opus codec.
no_streams.webm - Header, Info, & Tracks element from bear-320x240.webm slightly corrupted so it looks
like there are no tracks.
nonzero-start-time.webm - Has the same headers as bear-320x240.webm but the first cluster of this file
is the second cluster of bear-320x240.webm. This creates the situation where
the media data doesn't start at time 0.
bear-320x240-live.webm - bear-320x240.webm remuxed w/o a duration and using clusters with unknown sizes.
ffmpeg -i bear-320x240.webm -acodec copy -vcodec copy -f webm pipe:1 > bear-320x240-live.webm
vp8-I-frame-160x240 - The first I frame of a 160x240 reencode of bear-320x240.webm.
vp8-I-frame-320x120 - The first I frame of a 320x120 reencode of bear-320x240.webm.
vp8-I-frame-320x240 - The first I frame of bear-320x240.webm.
vp8-I-frame-320x480 - The first I frame of a 320x480 reencode of bear-320x240.webm.
vp8-I-frame-640x240 - The first I frame of a 640x240 reencode of bear-320x240.webm.
vp8-corrupt-I-frame - A copy of vp8-I-frame-320x240 w/ all bytes XORed w/ 0xA5.
Vorbis test data from bear.ogv (44100 Hz, 16 bits, stereo)

// Transport streams.
bear-640x360.ts - AVC + AAC encode, multiplexed into an MPEG2-TS container.
bear-640x360_ptswraparound.ts - Same as bear-640x360.ts, with a timestamp wrap-around in the middle, created with the below command:
ffmpeg -itsoffset 95442 -i bear-640x360.ts -c:v copy -c:a copy -muxdelay 0 bear-640x360_ptswraparound.ts
bear-640x360-hevc.ts - HEVC + AAC encode, multiplexed into an MPEG2-TS container.
// ISO-BMFF streams.
bear-1280x720.mp4 - AVC + AAC encode, mulitplexed into an ISOBMFF container.
bear-640x360.mp4 - Same as above, but in a different resolution.
bear-640x360-hevc.mp4 - Same content, but encoded with HEVC.
bear-320x180.mp4 - Same as above, but in a different resolution.
bear-640x360-trailing-moov.mp4 - Same content, but with moov box in the end.
bear-640x360-av_frag.mp4 - Same content, but in fragmented mp4.
// Non square pixels.
bear-640x360-non_square_pixel-with_pasp.mp4 - A non-square pixel version of the video track of bear-640x360.mp4 with PixelAspectRatio box.
bear-640x360-non_square_pixel-without_pasp.mp4 - A non-square pixel version of the video track of bear-640x360.mp4 without PixelAspectRatio box.
// Encrypted Files.
bear-640x360-v_frag-cenc-aux.mp4 - A fragmented MP4 version of the video track of bear-640x360.mp4
encrypted (ISO CENC) using key ID [1] and key [2] and with sample
encryption auxiliary information in the beginning of mdat box.
bear-640x360-v_frag-cenc-senc.mp4 - Same as above, but with sample encryption information stored in
senc box.
