non-bundled createAnswer uses more than one CNAME
Reported by fi...@andyet.net, May 31 2014 Back to list
What steps will reproduce the problem?
1. go to https://meet.jit.si
2. execute `focus.makeConference([]);` in the javascript console
3. check the createAnswerOnSuccess SDP in webrtc-internals, the a=ssrc lines with the cname

What is the expected result?
The CNAME is the same for both audio and video. See http://lists.w3.org/Archives/Public/public-ortc/2014May/0144.html and also bullet #http://tools.ietf.org/html/draft-ietf-rtcweb-rtp-usage-14#section-4.9

What do you see instead?
Different cnames. Note that meet.jit.si attaches audio and video as different streams (i.e. addStream is called twice) for the local media.


What version of the product are you using? On what operating system?
canary, build 274036 on windows 7

Please provide any additional information below.
BUNDLE'd streams (e.g. on apprtc) share the same CNAME.

Related to this, adding two streams with different resolutions (https://code.google.com/p/chromium/issues/detail?id=346616 -- in canary) results in different CNAMEs as well (non-bundled at least).

ah, different CNAMEs in createOffer as well when multiple video streams are attached.
Calling 
pc.createOffer(function (offer) {console.log(offer.sdp);}, console.error)
on
http://hancke.name/tmp/simulcast
should reproduce that.

This looks like it's not hitting m42.  Update it if I'm wrong.
