Ubuntu does not recognize "kate" subtitles format (default format in ogg)

[®om]

Ubuntu 9.10 and 10.04a3 do not recognize "kate" subtitles format, which is the subtitles format for ogv files.
When opening with totem, it searches for a codec, but doesn't find it, while it should be in gstreamer0.10-plugins-bad (according to some theora dev on freenode #theora).
VLC cannot open it either because it is not compiled with the option to include kate.

It is quite disappointing, ogg container (and theora codec) should be highlighted (and fully supported), it is and will be used in html5 pages, and more (for own dvd-rips for exemple).

To create such a file : ffmpeg2theora video.mpg --subtitles subtitles.srt -o video.ogv

Thank you for taking the time to report this bug and helping to make Ubuntu better. A new version of GStreamer is available in both Lucid and Maverick and we are wondering if this is still reproducible in any of those versions, May you please test and give us of feedback about it? Thanks in advance.

A developer who was working at the W3C on video accessibility and previously at Mozilla on video subtitles wrote "As for Ogg: my suggestion would be to find a way to encapsulate WebVTT into Ogg Kate (similar to how it already encapsulated SRT) and then also support that through the TextTrack API of HTML5."

WebVTT subtitle support can be enabled in Firefox 26 by going to about:config and changing media.webvtt.enabled from "false" to "true". It is scheduled to be enabled by default in Firefox 28, although I assume that is dependent on fixing https://bugzilla.mozilla.org/show_bug.cgi?id=921484 first. It might be a bit annoying until they fix https://bugzilla.mozilla.org/show_bug.cgi?id=887934 but I guess that can wait until later. In my opinion, fixing https://bugzilla.mozilla.org/show_bug.cgi?id=886353 and https://bugzilla.mozilla.org/show_bug.cgi?id=876505 can definitely wait until later.

https://bugzilla.mozilla.org/show_bug.cgi?id=921484 is fixed.

WebVTT subtitle support is finally enabled by default in Firefox 31. https://bugzilla.mozilla.org/show_bug.cgi?id=876505 has also been fixed.
