Re: [webrtc-pc] Missing CNAME in RID based simulcast offer (#2114)

Hi @aboba, I assume you meant @ibc :)

In my case it's ok with just having CNAME in the object model. Whether it must be in the SDP or not is indeed another subject. Note that CNAME is (theoretically) also sent in RTCP Sender Reports (within a SDES item) so the receiver can correlate it with the media SSRC (already known via SDP or RID).

In the other side, libwebrtc fails to match incoming SSRCs if the remote SDP doe snot contain `a=ssrc` lines with "cname" attribute, but that's another story.
