[FFmpeg-devel] rtpdec.c: AXIS 7401 RTCP RR Keep Alive SSRC
Fri Aug 14 18:34:23 CEST 2009
The bin worked, but I think there will be a problem when multiple users access the video server. The problem will be that each ffmpeg client will have the same SSRC. I wasn't able to test it, but it would violate the requirement that each client(s)/server have a different SSRC.

I fixed the client SSRC, but its supposed to be a random value (but fixed for the session). Furthermore, the code should really check to see if the client/server's SSRC's match and then select a new one. For our application, it seems to work OK with a fixed SSRC.

Can you test the attached patch? I expect it to work, but I prefer to be
sure (and I have no AXIS servers for testing).
