> Could you elaborate a bit to help me understand why that would be needed for FLEX-FEC when using RepairedRtpStreamId?

I just meant that, in case of option A above, FLEX-FEC would require
the same as RTX (when RID is in use and ssrcs are therefore not
signaled).


> I guess that use of RtpStreamId or RepairedRtpStreamId on RTP level (in the RTP and RTCP packets) should not matter much, neither for FLEX-FEC nor RTX, as long as it is clearly defined what it means?

I'm not against it. It's just that this requires a new draft about RID
and "complementary streams" (or include it into existing ones).
