 bear-320x240-video-only.webm - The video track of bear-320x240.webm.
 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-vp8a.webm - WebM VP8 video with alpha channel.

                           is the second cluster of bear-320x240.webm. This creates the situation where
                           the media data doesn't start at time 0.
