H264 RTP

[Chuck Crisler]

OK, the RTP header values are set in the call to gst_basertppayload_push() 
to push the buffer to the next element. The function uses the passed in 
GstBaseRTPPayload * object. That object might be part of the derived object 
that implements a GstStaticPadTemplate with some data. However, things like 
the RTP version aren't set there.

It is an embedded system and we don't quite have that freedom. :-(
