[14:06:54] Miguel A. Garcia leaves the room
[14:07:18] <stpeter> who else volunteered to take minutes? I'm doing so at http://tools.ietf.org/wg/mmusic/minutes
[14:07:29] Miguel A. Garcia joins the room
[14:07:39] <Lorenzo Miniero> Miguel, having problems with the platform?
[14:07:58] <Miguel A. Garcia> Yes, I am in the Ericsson Intranet, and I cannot get the audio
[14:08:10] <Lorenzo Miniero> which alternative are you trying?
[14:08:17] <Lorenzo Miniero> Slide 9: WG Status
[14:08:31] <Miguel A. Garcia> The HTML5 is the only option where I get some distorted audio, but useless
[14:08:47] <Lorenzo Miniero> the flash options don't work either? they usually do
[14:08:58] <Miguel A. Garcia> Flash does not work
[14:09:10] <Miguel A. Garcia> trying the HTTP stream via VLC, but does not work either
[14:09:16] Muthu Perumal joins the room
[14:10:34] <Lorenzo Miniero> we're testing them and they look fine
[14:10:46] <Lorenzo Miniero> are you filtered somehow?
[14:10:52] <Miguel A. Garcia> well, one problem is the Intranet and a firewall
[14:10:57] <Lorenzo Miniero> HTTP streaming assumes your client supports the Opus codec, by the way
[14:11:01] <Miguel A. Garcia> but the flash or HTTP streams should work
[14:11:21] <Lorenzo Miniero> HTTP works if your VLC supports Opus, I'm not sure older versions do
[14:11:38] <Cullen Jennings> Is firefox the only browser with opus right now ?
[14:11:41] <Lorenzo Miniero> Presentazione interrotta
[14:11:51] <Lorenzo Miniero> I think so, yes
[14:12:06] <Lorenzo Miniero> Slide 2: GOAL
[14:12:16] Cullen Jennings leaves the room
[14:12:20] <Miguel A. Garcia> I am using firefox
[14:12:36] <Jonathan Lennox> What version of VLC did you try?
[14:12:43] <Lorenzo Miniero> which version of Firefox? it may only be supported in the Nightly beta
[14:12:59] <Miguel A. Garcia> VLC 2.0.3
[14:13:08] <Miguel A. Garcia> Firefox 16.0.2
[14:13:11] <Lorenzo Miniero> Miguel as an ugly fallback, there's the phone number you can call
[14:13:23] <Lorenzo Miniero> Slide 3: ALTERNATIVES
[14:13:26] <Lorenzo Miniero> Nightly is v19.something
[14:13:46] <Jonathan Lennox> Opus was added in VLC 2.0.4
[14:15:23] <Miguel A. Garcia> I am going to install VLC 2.0.4

[16:13:50] EKR joins the room
[16:15:52] Martin Thomson leaves the room
[16:16:09] <stpeter> from RFC 3264...
RFC 2543 [10] specified that placing a user on hold was accomplished
by setting the connection address to 0.0.0.0. Its usage for putting
a call on hold is no longer recommended, since it doesn't allow for
RTCP to be used with held streams, doesn't work with IPv6, and breaks
with connection oriented media. However, it can be useful in an
initial offer when the offerer knows it wants to use a particular set
of media streams and formats, but doesn't know the addresses and
ports at the time of the offer. Of course, when used, the port
number MUST NOT be zero, which would specify that the stream has been
disabled. An agent MUST be capable of receiving SDP with a
connection address of 0.0.0.0, in which case it means that neither
RTP nor RTCP should be sent to the peer.
