RTP handling and clock-rates

[Jon Mandrell]

I am using gstreamer 1.2 (the same thing happens with 1.6). I am attempting to tune to an RTP stream provided by an external device, and I'm using the following pipeline as a test:


GST_DEBUG=*:2 gst-launch-1.0 -v udpsrc multicast-iface=eth2 buffer-size=8000000 do-timestamp=true uri=udp://226.0.0.11:2400 ! application/x-rtp,media=video,clock-rate=90000 ! rtpbin ! fakesink silent=false

I do see packets coming out of the fakesink, but I'm also getting the following message logged between every packet:

0:00:00.328454488 12399  0x84aa260 WARN               rtpsource rtpsource.c:994:calculate_jitter: cannot get clock-rate for pt 33

How do I let it know the clock-rate? I had hoped providing the capsfilter would handle that.?
