Dear all,
The minutes of today's phone telecon are available for review at
http://www.w3.org/2011/06/08-mediafrag-minutes.html (and in text format
below).
In a nutshell, we aim at transitioning to CR by the end of this month.
Silvia has just launched a new discussion thread: stepping back and
renaming the "chapter" dimension as "id" or "cue". Once we agreed on
this we can transition.
I will also start a new thread for approving batch of test cases on the
mailing so that we discuss only the corner cases or the ones we flag as
non consensus during the upcoming telecon before the summer break.
Best regards.
Raphaël

Raphael: I hope that by TPAC we do not have issues any more to deal
with
Silvia: one of the change was to rename "id" into "chapter"
... I wonder if this was a good move
... in WebVTT, we add tracks (captions, audio descriptions) and cues
(time stamps) have identifiers
... I wonder if #id would not be better than #chapter for a
dimension that addresses a section by name
... tracks introduced in HTML5 with 5 possible types

[15]
http://www.whatwg.org/specs/web-apps/current-work/multipage/the-iframe-element.html#dom-texttrackcuelist-getcuebyid(in
<doublec> but 'chapter' in media fragments is just a shortcut for
#t=... isn't it? It's not related to the 'id' used in the cue?
Yes Chris
<silvia> example cue:
<silvia> 00:00:01.000 -> 00:00:08.000
<silvia> asdfasf
<silvia> then we get "example cue" as the identifier of this cue
<silvia> and we can address it by getCueById("example cue") in HTML5
Raphael: so the question is should we change back to "id" or another
dimension name?
<silvia> and we can address it by
[16]http://example.com/video.ogv#example%2dcue
[16] http://example.com/video.ogv#example%2dcue
<doublec> If the user uses #id=example cue, does that mean it's the
same as #t=1,8?
<silvia> yes
<doublec> so there needs to be a text track for id to work?
<davy> maybe we should name it 'cue': video.ogv#cue=example%20cue
<silvia> I like Davy's idea
Silvia: Cues are defined in a text track, yes
Raphael: but if the media has embedded cues?
Silvia: we are not introducing any dependencies, but we just make
sure it can work with HTML5
Raphael: we discuss this on the mailing list, Silvia will start a
thread to discuss whether we should name this dimension "id", "name"
or "cue"
