ACTION-185?
<trackbot> ACTION-185 -- Yves Lafon to book zakim for the 2 days meeting of the group on Mon 1st and Tue 2nd Nov -- due 2010-09-29 -- OPEN
<trackbot> http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/185
<foolip> November 1 and 2, any time between 0800 and 1800 in UTC+2
Raphael: for Silvia and Philip, could you write down time slot where we can phone you
<silvia> Monday is better for me than Tuesday - it's both in the afternoon/evening for me, I think
<foolip> in other words, any time is fine, since I'm in the same timezone as TPAC
<silvia> if you start early, I can join in the mornings
ACTION-189?
<trackbot> ACTION-189 -- Raphaël Troncy to put the top-level production rules back into the document (in section 4.3.5 or 4.1) -- due 2010-10-06 -- OPEN
<trackbot> http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/189
<silvia> ok
<foolip> can't say anything until I see the actual suggestion for the spec
Raphael: I will implement the ACTION-189 in the spec and ask all the group if we can close this issue
Raphael: problem with pixels, are we talking about physical pixels or css pixels?
Silvia: pixels in video are always a problem
Raphael: I'm looking for a reference that we could use so that any developers understand what we are talking about
Philip: this definition is provided by HTML5 and not CSS
<foolip> http://www.whatwg.org/specs/web-apps/current-work/multipage/video.html#concept-video-intrinsic-width
<foolip> http://dev.w3.org/html5/spec/video.html#concept-video-intrinsic-width
<scribe> ACTION: troncy to update our spec to talk about video intrinsic width [recorded in http://www.w3.org/2010/10/20-mediafrag-minutes.html#action01]
<trackbot> Created ACTION-190 - Update our spec to talk about video intrinsic width [on Raphaël Troncy - due 2010-10-27].
<foolip> well, there's an issue we discussed at FOMS
Davy: this issue is solved
<foolip> ah :)
Davy: there is indeed too many byte ranges to send to the UA
<foolip> do you always redirect, or just when number of ranges > n ?
Davy: therefore, we send a redirect pointing to a media fragment with the ?
<foolip> always seems simpler :)
Davy: currently, always redirect
Raphael: the UA issues a new request with the query parameter
Davy: yes, and we had a Link header pointing to the master resource
Philip: we could implement that
but I really wonder if it is useful
... we will always need a specialized server
... so the query parameter migt be enough
Davy: there are other scenarios
where the # is useful
... we should have both
... even if in the retrieval scenario, the # will always be
converted into the ?
Philip: what should we do with the name dimension
Davy: in MP4, refer to the cue points; in Matroska, refer to the chapters names
Philip: OK, yes the chapters are part of WebM
<silvia> and Ogg can have chapters through a srt chapter track in Ogg Kate
Raphael: ok, so it seems
important that we cover the name dimension even if it is
limited to chapter names!
... last issue from Philip, make the hour optional in
specifying the time dimension
... currently, we need one or two digits
... but most clips have duration less than 1 hour
... but the grammar will be more complicated
... because we could then have just one digit for the
minutes
Philip: in WebSRT, the hours are optional
Raphael: I suggest we discuss this at the F2F
<silvia> I would support that if you can find a grammar to describe it correctly - it's also more complicated to implement then, btw
Look at the demos at http://www.w3.org/2008/WebVideo/Fragments/code/plugin/demos/
Davy: yes, Ninsuna understands
range request with SMPTE time codes
... and answers with smpte time codes
... though I need to check
Yes Silvia, that's also our conclusion, re the grammar
scribe: the questio is who is willing to work out this more complex grammar? I suggest to hack this during the f2f but if you want to work on it before, please feel free
<silvia> do it with Yves - he is good at that stuff :)
no other topic to discuss
meeting adjourned
<foolip> ok, about the syntax then
<foolip> it's be simplest to just say that all components are 1 or 2 digits
<foolip> ugly, but simpler, and simple is good :)
:-)
<foolip> but let's discuss that further later
we will see what the grammar should loook like, indeed, Yves might be able to sort that out elegantly
