Hi Thomas, Even though it is too late to suggest anything but to help others, here are some things: 1. On UDPSRC u need to set the caps as a property. 2. In the code u request a pad then link it before u request another 3. You need not to request source pad, you will get a call back in that you check the direction of PAD and link it to the next bin you want to link. Please correct me if i am wrong. As well apologies for replying late, but was stuck up with some things. Thanks and Regards Manish <div class="gmail_quote">On Fri, Jun 27, 2008 at 5:34 AM, Thomas Winkler <<a href="mailto:wi-tom@gmx.de">wi-tom@gmx.de</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Thanks to all who helped to solve my problem. Now I have a Receiver and a Sender which works fine. I've attached my sample-application for Sender and Receiver. PS: My problem was, that I've forgotten to create a capsfilter on my Server-Side and I've exchanged the pad_requests From: ps->send_rtp_src0 = gst_element_get_static_pad(rtpbin, "send_rtp_src_0"); ps->send_rtp_sink0 = gst_element_get_request_pad(rtpbin, "send_rtp_sink_0"); To: ps->send_rtp_sink0 = gst_element_get_request_pad(rtpbin, "send_rtp_sink_0"); ps->send_rtp_src0 = gst_element_get_static_pad(rtpbin, "send_rtp_src_0"); because in the Reference it's described that the "send_rtp_src_%d" pad is automatically created if a pad_request to "send_rtp_sink_%d" is called. Thanks to all people who helped. For all people who are looking for a rtp pipeline for gst-launch, I've attached a gstrtp_pipe file which includes sender and receiver pipeline-command. <div class="Ih2E3d"> Greetings, Thomas > -----Ursprüngliche Nachricht----- > Von: <a href="mailto:gstreamer-devel-bounces@lists.sourceforge.net">gstreamer-devel-bounces@lists.sourceforge.net</a> [mailto:<a href="mailto:gstreamer-">gstreamer-</a> </div>> <a href="mailto:devel-bounces@lists.sourceforge.net">devel-bounces@lists.sourceforge.net</a>] Im Auftrag von Thomas Winkler > Gesendet: Freitag, 27.
