I found the problem in my code: I did not set the port to listen to. But I'm not able to get the stuff up. If I write: gint value = 1234; g_object_get_property(G_OBJECT(udpsrc), "port", &value); I get a seg fault. What is the correct way to set the port of the udpsrc?

For the receiver, I am creating a udpsrc,  depayloader, decoder and videosink, and linking them together.
