The video element description states that Theora, Voribis and Ogg
container should be supported. How should closed captions and audio
description tracks for accessibility be supported using video and
I was pointed to a page outlining some previous discussion on the issue:
Is there a way of identifying which track is the closed caption track,
which is the alternate audio track, etc? How are other implementors of
the video element handling this issue?
Is CMML for the closed captions viable? Or a speex track for the
alternate audio? Or using Ogg Skeleton in some way to get information
about the other tracks?
