[media] raising bugs in W3C bug tracker for LC

Hi media a11y ppl,

I just came across the note that Mike Smith has forward to the HTML WG:

I now wonder if we should discuss this also in the media a11y subgroup and
ascertain all the things that we want solutions for are actually raised in
the HTML WG bug tracker. I know we have Issue-9, but is it actually going to
be enough?

As it stands, we have the following bugs:

1. On Markup for including external text tracks

"Introduce declarative markup to associate timed text resources with media
elements"
http://www.w3.org/Bugs/Public/show_bug.cgi?id=9471
-> for which I have already suggested moving much of the WHATWG proposal
into the W3C version.


2. On handling multitrack media resources

"Handling of additional tracks of a multitrack audio/video resource"
http://www.w3.org/Bugs/Public/show_bug.cgi?id=9452
-> which has been reflected to us for proposing a solution; this should be
our next focus for technical discussion. It will include a solution for
"clear audio" and for "sign translation", so cover a fair bit of ground.


3. Several on WebSRT

"There is not a clear difference between "subtitles" and "captions". These
are mostly used to describe "closed captions" (binary transmissions in TV
broadcasts) vs "subtitles" (text files), as far as I know"
http://www.w3.org/Bugs/Public/show_bug.cgi?id=9773

"Allowing A WebSRT voice declaration when the cue payload is WebSRT metadata
text does not make sense, I think"
http://www.w3.org/Bugs/Public/show_bug.cgi?id=10619

"..multiple cues are supported at once. But many SRT players don't actually
support more than one SRT subtitle at once.."
http://www.w3.org/Bugs/Public/show_bug.cgi?id=9777

 "Percentages for text positioning don't seem better than using the actual
video dimensions"
http://www.w3.org/Bugs/Public/show_bug.cgi?id=9776

---

So, the only thing I can see missing is a solution for the requirement area
"Content navigation by content structure". We haven't discussed any
potential technical approaches to this yet, but I think it is important
enough to include that in this version of the HTML5 draft. It may well be
that all we need is a means to switch easily between available timed text
tracks and to make direct URLs to cues available. But we haven't got into
the depth of this and I think we may need to make sure that there is a
placeholder for this discussion in the HTML5 bug tracker.


Cheers,
Silvia.
