<raphael> Regets: Thomas, Silvia
damn!
<raphael> scribe: yves
<raphael> scribenick: Yves
approval of last week minutes
<raphael> +1
<Yves> +1
<davy> +1
RESOLUTION: minutes approved http://www.w3.org/2011/01/12-mediafrag-minutes.html
Philip sent some patches that needs to be incorporated in the spec
As we did lots of changes, we need another LC (that will be short).
I would like that we decide on the LC next week
aiming for 3 weeks review time
any objection with the plan?
<erik> no
<hackerjack> no
Davy: do I have to include RTSP in the spec before next week?
Raphael: yes
Davy: I will try
document changed a lot in december but not a lot since then
we need to rephrase slightly the part of the spec about SMPTE timecodes
also new video codec don't have fixed framerates, we need to address that
jack: 99.99% of existing movies files will have fixed framerate even if the format allows dynamic framerate
raphael: we need to address this case
Jack: starting to rethink my position on that issue, it makes sense to present the whole fragment in that case
should it be implementation notes?
Raphael: in the final document, the things that we may remove because of lack of implementation might go in a non-normative appendix
Yves: fine as long as it is clear that it's not normative and there because of lack of implementation
Davy: variable framerate is usually not implemented as the encoder needs to communicate with the packager, and not sure it's implemented now. Also SMPTE time codes at a frame-basis should be there
Jack: how about implemetation ?
Davy: might try to get one at least partial
Jack: if people are interested in that, they should demonstrate their interest with code, even if it's a toy implementation
Raphael: would like to invite Addison to discuss issue 17 about IRI and track names
would feb 2 be ok? (ie: get critical mass here)
<raphael> I18N discussion: http://lists.w3.org/Archives/Public/public-media-fragment/2010Jun/0056.html
raphael: we also need to dedicate a complete telcon on test cases.
erik: will issue 19 be solved by next week?
raphael: yes
<raphael> Bug: http://www.w3.org/Bugs/Public/show_bug.cgi?id=10723
Bug was rejected because it was multiple things in one bug, Silvia had an AI to open several bugs
<raphael> I have been dropped :-(
Yves: only the last one about having to stop at the end of the fragment needs reopening
action 204 will be dropped
<trackbot> Sorry, couldn't find user - 204
the header syntax should be checked in the tests
RTSP will be added soon
Davy has some updates on that front
<raphael> drop ACTION-204

raphael: wondering about server-side tests
davy: we need extra test cases,
yes
... but we have the template for test cases
Raphael: there are two things to check, URI parsed as it should and HTTP request sent as it should, and the second point is to verify the behaviour (graphical)
jack: if we have a client saving the file, we can do automatic testing
Yves: but there are things that we can't test that way (like displaying the complete timeline)
Raphael: a few things needs to check manually, which is fine
Jack: we need to check what SVG
or CSS people are doing to test graphical output
... also if the number of manually tests is small...
s/manually tests/manually verifiable tests/
Jack: the first thing is to review all the current tests
Davy: we have also an issue with sources for tests
Raphael: can we make files or is transcoding too difficult?
Jack: ffmpeg might help there
Raphael: please ask on the ML.
<hackerjack> yes
<raphael> One question: should we use one of the movies in the spec and in the test cases ?
Raphael: should we use in the test cases one of the movies we have in the agenda? (ie: one with the right license)

<hackerjack> I would prefer not to use the suggested movies
<davy> http://www.w3.org/2008/WebVideo/Fragments/media/spatial_30fps.webm ?
Jack: we should create synthetic movies, easier to do checking (like switching backgrounds on boundaries we are about to tests)

erik: should we drop all the AI assigned to Michael?
raphael: safe ot drop them
Erik: we need to talk about use cases as well (from Shiraishi San)
<Nobu> Thank you, I am on IRC now.
Erik: also who is attending the workshop in Berlin?
Raphael: no
Erik: I should be there
ADJOURNED
<Nobu> I
<raphael> Nobu: we agree to continue the discussion on your use case on the mailing list
<raphael> please, create a wiki page if you want
<Nobu> I see, thanks.
<raphael> The Use Cases and Requirements document is sort of "on hold" ... which means, we will update it at the end of the rec track process
