title: Looking for examples showing usage of UDP source element in a C++ gstreamer application
body: <p>I've been reading the documentation but it's a little tough to see how to set up a pipeline in C++ using the UDP source element.<br>
  If anyone knows of an example, or could post a snippet showing how to do it, I'd be very grateful.</p>
  
  <p>Is it enough to do </p>
  
  <p>source = gst_element_make_from_uri(GST_URI_SRC, "udp://@:15004", "source");</p>
  
  <p>and then use the result as the first element in a pipeline?</p>
