<div style="font-size:12pt">I was able to run an example ( gst-plugins-good-1.18.1/tests/examples/rtp/server-rtpaux.c) with rtpbin and a pad probe ( just like you suggested). The problem for me with gst-rtsp-server is that I don't know how to access rtpbin
and udpsinks inside gst-rtsp-server. <br>

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