How to gurantee lip sync in the multicasting mode

[Nathan]

Dear Nicolas,

The gstreamer use RTCP to guarantee audio video sync, and when there is only
one receiver, this receiver(udpsrc) will report rtcp packages, which
contains the timing information to the transmitter（udpsink), then the
transmitter can adjust the delay between audio and video pipeline.
However, when there is multiple receivers, (I might be wrong here) so there
are multiple receivers reporting the rtcp packages to the transmitter. I was
thinking this might be the reason when there is multiple receivers, the lip
sync is gone.

My question is, shoud I set the rtcp related pipeline works in the
multcasting? How the transmitter pipeline handles different rtcp packets
from different receiver?

Do yo you have any idea about this?

Thanks very much,

Jun
