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

I'm not sure what change is being asked for here.
We've got cname as part of RTCRtcpParameters, which is a member of RTCRtpParameters, whch is the base dictionary for RTCRtpSendParameters and RTCRtpReceiveParameters, which can be read by getParameters() on their respective sender/receiver objects.

So you can figure out what CNAMEs are in use once the browser has started using them (and lack of support for this field is a browser bug).

As commented above, CNAMEs are not required to be signalled in SDP. If there exists a need to have them in SDP, draft-alvestrand-mmusic-simulcast-ssrc seems like a possible avenue, but this is a spec entirely outside the webrtc-pc specification, so shouldn't be tracked in this bugtracker.

Can we close this as "no change needed"?
