Hi,

I am not sure about your claim. The SSRC of the media sender is always there
, otherwise how can RTCP report or request action on a media stream. It is
true that for some of the RTCP messages like TMMBR it is inside the FCI part
of the message but it is there. As for understanding all RTCP messages, it
is not required today and the support is negotiated in SDP. 

For video streams I assume that RTCweb will mandate the support of controls
like FIR and TMBBR.

 

Regards

Roni Even

Another +1 for multiplexing everything together. My only worry is that the
base spec for RTCP doesn't mandate that SSRC is included in every RTCP
message type, and thus you could end up with the multiplexing layer needing
to understand every  RTCP messaged used for video (TMMBR, TMMBN, etc)
