This is a very fundamental choice of how SDP is going to deal with RTP
sessions that include multiple media streams, i.e. SSRCs carrying
different media sources and negotiation of media stream related
information and parameters.

I understand some drafts are under preparation here.

This is definitely something that will impact CLUE also.

This is more an WebRTC focused issues, but it has clearly overlap with
the relations discussion on how you identify media sources, different
encodings of the same media stream (in simulcast and scalable coding)
their repair streams all the way up to WebRTC specific concepts of
MediaStream.

For this my colleagues and I are preparing a draft. I don't expect it to
be available before second half of next week.

I think this is relevant for CLUE in the perspective of trying to
understand what is common abstractions and what is not.

Cheers
