Re: [Debconf-video] video annotations for DebConf13
Hi Silvia,
Thanks for the link! This is the sort of usage we're envisioning for our
tools.
TextTrack/WebVTT seems promising, but browser support seems a little lacking,
which makes me wonder how much it can do for us right now. Specifically,
Firefox doesn't seem to support it, and our current plans are to support
Chrom{e,ium} and Firefox.[0]
https://bugzilla.mozilla.org/show_bug.cgi?id=629350
https://developer.mozilla.org/en-US/docs/HTML/WebVTT
https://developer.mozilla.org/en-US/docs/HTML/Element/track
That said, WebVTT seems useful as a data model and maybe even as an internal
representation for our work. Indeed, some of our previous projects have used
the similar SRT format for subtitles and annotations.
So I think we'll be rendering subtitles ourselves for the time being and
switching to <track> when it's a little better supported.

P.S. Will you be at Debconf? I'd love to get your feedback on how this project
turns out in person.
[0] Our reasoning is that they're the most popular free software browsers and
often lead in supporting useful new technology, and that supporting both
encourages us to only use new technology that is likely to see adoption
in the future (compare the current situation with the
incompatible/non-standard web audio APIs).
