Provide specification or explanation for subtitled content
Reported by renru...@gmail.com, May 19 2010 Back to list
I see subtitles as an fundamental part of a media specification, specially
for accessibility purposes, and I don't see them specified, not even
mentioned in the WebM Project site faqs and docs.

While subtitles don't have as many different specifications and
implementations as video and audio formats, and even the Matroska
documentation writers took their time to describe the few of them, I'd like
to see some sort of guarantees if webm-specific media players will show my
embed [optionally multi-language] subtitles or not.

So this is request to the project team to discuss and clarify this
standardization issue of the Subtitle Track, if there is any.

Commenting on myself, correcting the "mention" part above, after a google search in
the site(http://www.webmproject.org/code/specs/container/):

Demuxer and Muxer Guidelines

Initial WebM release does not support subtitles.
    * WHATWG / W3C RFC will release guidance on subtitles and other overlays in HTML5
<video> in the near future. WebM intends to follow that guidance.

I see this remains an open issue to be resolved in the future.

Closing for now. Our technical approach has been decided and it's under active development.
