[gst-devel] How to specify type of sink or src pad in gstrtpbin

[Thomas Winkler]

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.

Greetings,
Thomas
