The easiest way is to use a pad probe on the udpsink that is sending
out the RTCP packets. Just remember that the callback you set there
will be invoked from inside an arbitrary gstreamer thread, so you
should not do non-trivial processing inside that. You should signal a
different thread and do the work there, or invoke it on the main loop.
