Hi Guillaume, you cannot make the telecon?

Yves, try to dial another number?

Topic 1. ADMIN

Propose to accept the minutes of last telecon?

All: accept without changes

RESOLUTION: minutes accepted

Topic 2. F2F meeting

Raphael: we need to discuss the agenda, build it together
... what are your objectives?

Jack: it would be good if we could discuss concrete implementations
... mine could be ready, if we clarify the range unit syntax
... then it is a 1/2 day coding

Raphael: my expectation would be also to discuss test cases, and of course the main document

Yves: we need to build a story around the 4-ways handshake
... also talk about the link header

Topic 3. Main Document

3.1: Syntax

ACTION-46?

<trackbot> ACTION-46 -- Yves Lafon to check the formal validity of the grammar -- due 2009-03-25 -- OPEN

<trackbot> http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/46

close ACTION-46

<trackbot> ACTION-46 Check the formal validity of the grammar closed

Yves: I have built a small parser in java / cc that validates the grammar
... no mistake in the grammar

3.2 Use Cases and requirements

Silvia and Guillaume will finish it by the end of this week

3.3 Technology Survey

Erik would like to know if he could take action to improve this section

Raphael: what changes can we bring?
... I think for example that the formal grammar of TimedText is unnecessary

Jack: what about a companion document ?
... I would suggest summarize the wiki page in the main document
... and provide an informative reference to the complete wiki page
... I would like to have this technology survey perhaps published as a Working Group note since I find it useful

Davy: 5.1 should be in the ref section

Raphael: yes, the examples come actually from 5.3

<scribe> ACTION: Erik to summarize the content of the wiki page to put in the main document, with few examples and a short story [recorded in http://www.w3.org/2009/03/25-mediafrag-minutes.html#action01]

<trackbot> Created ACTION-51 - Summarize the content of the wiki page to put in the main document, with few examples and a short story [on Erik Mannens - due 2009-04-01].

3.4 HTTP implementation

Raphael: I would like to replace all the examples with the real videos Jack took in Ghent

<scribe> ACTION: Raphael to replace all examples in the wiki page with the video Jack took [recorded in http://www.w3.org/2009/03/25-mediafrag-minutes.html#action02]

ACTION-49?

<trackbot> ACTION-49 -- Yves Lafon to draft the HTTP-Range syntax for different units (completing all the syntax for the two way handshake) -- due 2009-03-25 -- OPEN

<trackbot> http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/49

Yves: I will definitively make that before the f2f
... starts with seconds first, so to not block implementation

Jack: do you want to copy the movies on the W3C server?

Raphael: yes, to have permanent URI for these resources
... which format we will use? mp4, ogg?

Jack: ffmpeg should be able to slice the movie, need to check

Davy: we have a piece of software that should be able to slice a media file independantly of the codec format
... I will demo this software during the f2f meeting

Yves: media.w3.org works on Apache, would be good to check for deployment

<scribe> ACTION: Jack to check whether ffmpeg can slide movies easily, need for implementation on client and server side [recorded in http://www.w3.org/2009/03/25-mediafrag-minutes.html#action05]

<trackbot> Created ACTION-53 - Check whether ffmpeg can slide movies easily, need for implementation on client and server side [on Jack Jansen - due 2009-04-01].

Yves: also consider the file:// protocol, everything on client

Davy: I'm also experimenting to provide a RTSP implementation
... I could report my current work at the f2f meeting

<raphael_> meeting will be back at the normal hour next week
