Grouping/linking RTPSession objects

As I have understood RFC3550 you must put related streams on different
SSRCs, for example, one sender might have video at UDP port 5000/1 and
audio at 5002/3 with different SSRCs. Then, these different streams
are synchronized by correlating their timestamps to a NTP stamp in a
sender report.

How does ccRTP implement this behavior?

Thanks,

-Kevin

Hello,

ccRTP does not implement synchronization among different sessions, it
just handles sessions. It is up to the application or whatever using
ccRTP to get the SR and NTP stamps from the sources and then do
inter-media synchronization. As far as I know, ccRTP does not do any
function above the RTP session "layer".

I see this is outside the scope of the RFC now. Thanks
