 bear-320x240-audio-only.webm - The audio track of bear-320x240.webm.
 bear-vp9.webm - VP9 video only WebM file.
 bear-vp9-opus.webm - VP9 Video with Opus Audio.
 bear-vp8-webvtt.webm - WebM VP8 video with WebVTT subtitle track.
 bear-1280x720_avt_subt_frag.mp4 - Fragmented bear_1280x720.mp4 with text track
                                   containing srt from bear-vp8-webvtt.webm as
                                   a 'subt' handler type.
 bear-1280x720_av_frag.mp4 - Fragmented bear_1280x720.mp4.
 bear-1280x720_av_frag-initsegment-mvhd_version_0-mvhd_duration_bits_all_set.mp4:
   Just the first initialization segment of bear-1280x720_av_frag.mp4, modified to
   have the mvhd version 0 32-bit duration field set to all 1's.
 bear-vp8a.webm - WebM VP8 video with alpha channel.
