Ok, I understand. Please let me explain my problem. I have made an application which has basically
	one pipeline sending audio to RTP with alsasrc ! rtpL16pay ! udpsink  and
	one pipeline from RTP to audio with udpsrc ! gstrtpbin ! alsasink.
I run this application on two machines exchanging audio.

After 20 seconds I get a time-out callback from gstrtpbin and then a gstreamer warning "unknown SSRC".
That gave me the impression that gstrtpbin was expecting RTCP. However I do not request RTCP pads.
I get the RTP pads from gstrtpbin by the on-pad-added callback at the moment it receives RTP stream.
Then I link these new pads to the alsasink.

Any idea were this timeout comes from?
