v4l2src on rtsp-server

[Chuck Crisler]

Obviously there is a caps negotiation problem. Try adding omx_h264enc:4 to
your gst_debug setting to try to see what caps it is expecting. Just for
grins you might try changing your capture format, though I can't suggest
why the pipeline elements would behave differently in the rtsp rtpbin than
outside. But try it to see what happens.
