I am having a client and a server, the server sends rtp data well but the client is failing somehow. I am having a problem linking the rtpbin recv_rtp_src_%d_%d_%d Element to a payload element. here's my Linker /* rtpbin = gst_element_factory_make ("gstrtpbin", "rtpbin"); videosink = gst_element_factory_make ("rtptheoradepay", "videosink"); */ static void pad_added_cb (GstElement * rtpbin, GstPad * new_pad, GstElement * depay) { GstPad *sinkpad; GstPadLinkReturn lres; g_print ("new payload on pad: %s\n", GST_PAD_NAME (new_pad)); sinkpad = gst_element_get_static_pad (depay, "sink"); g_assert (sinkpad); lres = gst_pad_link (new_pad, sinkpad); g_assert (lres == GST_PAD_LINK_OK); gst_object_unref (sinkpad); } this is how I call the method. g_signal_connect (rtpbin, "pad-added", G_CALLBACK (pad_added_cb), videodepay); this is the error I get bash $ ./client_video_stream starting receiver pipeline new payload on pad: recv_rtp_src_0_3343416118_96 ** ERROR:client_video_stream.c:33:pad_added_cb: assertion failed: (lres == GST_PAD_LINK_OK) ********* Please help
