[20:36:26] <Meetecho> is it up now?
[20:36:30] ABHISHEK RANJAN leaves the room

[20:39:32] <Randell Jesup> meetecho: another error - (no releoad was required) MeetechoError askisrecord error  (line 1182):
[20:40:05] <Meetecho> ack, will debug this ex post
[20:40:19] <Randell Jesup> magnus's audio was really bad (mic issue?)
[20:40:53] <Varun Singh_4171> was bad for me as well
[20:41:34] Paolo Saviano joins the room
[20:43:20] <Randell Jesup> This is fine
[20:44:27] <Varun Singh_4171> contact person is Zahed?
[20:44:35] <Varun Singh_4171> great.
[20:44:42] <csp> I’m happy to join the design team
[20:44:48] Varun Singh_4171 too
[20:44:54] <Randell Jesup> I can help out some
[20:45:42] <Varun Singh_4171> mic: is "rmode" a single bit information?
[20:46:05] ABHISHEK RANJAN joins the room
[20:46:30] ben joins the room
[20:46:42] hta joins the room
[20:47:16] bubbelman joins the room
[20:48:07] <Varun Singh_4171> mic: has anyone considered piggybacking this information as RTP header extensions instead of RTCP?
[20:48:20] <Jonathan Lennox> Varun: ack
[20:48:41] ABHISHEK RANJAN leaves the room
[20:48:43] <Roni Even> Note that RTP is unidirectional
[20:49:32] <Varun Singh_4171> mic: Agree, if both sides are sending media.
[20:50:45] <Jonathan Lennox> Varun: do you still need the relay?
[20:51:08] <Varun Singh_4171> Jonathan: I am fine for now
[20:52:31] <hta> Pontification: the ultimate piggyback scenario is where you piggyback all RTCP packets on RTP packets. I suggest we should be pursuing such optimizations after we have the basic mechanism in place.
[20:52:53] <Varun Singh_4171> mic: does SBD need data from SSRCs outside the scope of the RTP session?
[20:53:57] Bernard Aboba joins the room
[20:54:15] <Varun Singh_4171> got disconnected, network error. was there a response?
[20:54:17] <csp> Re pontification: that optimisation seems like a general update to RTP/RTCP, rather than something specific to this problem
[20:54:30] <Jonathan Lennox> Varun: he doesn't know, ask the SBD authors.
[20:55:02] Varun Singh joins the room
[20:55:17] Varun Singh_4171 leaves the room
[20:55:50] <Varun Singh> thanks, have been dropping in and out.
[20:56:58] <Varun Singh> I am interested to contribute too
[21:00:54] <Randell Jesup> hta: I had RTCP piggyback in header extensions back in 2005ish in the Worldgate Ojo (to deal with  SBCs that weren't forwarding RTCP (UGH))
[21:02:00] <Randell Jesup> We needed RTCP there for a) rtcp-fb NACK, b) APP messages with congestion control info
[21:02:06] <Varun Singh> mic: should flexible-fec need to be know about this?
[21:02:56] <Varun Singh> mic: flex fec has retx covered.
[21:03:33] ABHISHEK RANJAN joins the room
[21:03:46] <Varun Singh> mic: how would old retx use this? as in are we expecting them to change their implementation?

[21:16:54] <Bernard Aboba> mic: What about TL0PICIDX?  We have discussed this in the last meeting.
[21:17:03] <Jonathan Lennox> Bernard: now on that slide.
[21:17:42] <Bernard Aboba> It also exists in VP9, too.

[21:27:05] <Bernard Aboba> done
[21:32:30] <Bernard Aboba> I think it should be in.
[21:32:33] <Bernard Aboba> hummmmm
[21:32:38] <Randell Jesup> hum yes, in

[21:33:34] <Randell Jesup> \o/
[21:34:20] <Varun Singh> slide updated?
[21:34:35] <Jonathan Lennox> Should be showing "Overview" of codec control deck
