- silvia should now be muted
- 09:21:05 [raphael]
- Raphael: curently 2 groups (editors and contributors) while these roles are not really defined by W3C, not consistently used depending on the spec
- 09:21:24 [raphael]
- ... Suggest that Silvia and Davy jump to the editors group, they have edited most of the spec
- 09:22:16 [silvia]
- zakim, unmute me
- 09:22:16 [Zakim]
- silvia should no longer be muted
- 09:22:31 [raphael]

- ... I will apply the changes on the spec
- 09:24:14 [raphael]
- ACTION-161?
- 09:24:14 [trackbot]
- ACTION-161 -- Silvia Pfeiffer to integrate the test cases into the spec -- due 2010-04-21 -- OPEN
- 09:24:14 [trackbot]
- http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/161
- 09:24:39 [davy]
- Silvia: waiting for a few issues that are still issues
- 09:25:06 [davy]
- ... 1. #t=a,a and a >= 0 (#2)
- 09:25:26 [davy]
- ... is an empty fragment
- 09:25:43 [davy]
- ... if we send it to the server, we get a 416
- 09:26:33 [davy]
- ... question is whether the client should send it to the server or not, since it can detect there will be an error
- 09:28:41 [davy]
- raphael: empty fragment -> UA cannot display anything
- 09:29:34 [erik]
- q+
- 09:29:50 [raphael]
- zakim, ack
- 09:29:50 [Zakim]
- I don't understand 'ack', raphael
- 09:32:41 [raphael]
- Silvia: we need to have a consistent reaction of media fragment aware browsers
- 09:32:50 [raphael]
- ... for legacy browsers, they will react as for HTML
- 09:33:31 [raphael]
- Discussion about the empty fragment such as #t=a,a when a>=0
- 09:34:02 [raphael]
- Silvia: the UA still sends a range request and should get back an error 416
- 09:34:15 [raphael]
- Davy: but the UA knows it is a semantic error, why sending a request at all ?
- 09:36:28 [raphael]
- Silvia: the UA could simply do nothing ... irritating, but this is happening with HTML
- 09:37:16 [raphael]
- ... the fragment is not interpreted ?
- 09:37:37 [raphael]
- ... we could just get the header data of the media file, but stop, not downloading any content !
- 09:38:51 [raphael]
- ... for example, a Range Request with an empty fragment and only "include-setup"
- 09:39:02 [raphael]
- ... the server sends the header data of the media resource
- 09:39:24 [raphael]
- ... with a 206 OK for the header data
- 09:39:42 [silvia]
- zakim, mute me

- silvia should now be muted
- 09:39:52 [raphael]
- s/206 OK/206 Partial Content
- 09:40:21 [davy]
- raphael: we could apply this solution for the three cases
- 09:40:51 [raphael]
- Similar solution for all non-existent or illegal fragments
- 09:41:16 [raphael]
- ... see cases detailed at http://lists.w3.org/Archives/Public/public-media-fragment/2010May/0021.html
- 09:41:55 [davy]
- Action: troncy to send a resolution on handling non-existing or illegal fragments to the mailinglist
- 09:41:55 [trackbot]

- 09:46:51 [raphael]
- ... will send the version to Davy and Silvia for testing now
- 09:46:57 [raphael]
- ... + a readme :-)
- 09:47:15 [raphael]
- Davy: work on making Ninsuna acting as a proxy
- 09:47:36 [raphael]
- Raphael: add a parameter in the proxy to specify a proxy ... so get media fragments URI on any MP4 videos on the web
