Sure, when testing UDP w/MPEG-TS, I use VLC 1.1.0 as the sender with the
following command line:

  cvlc -v -L <file_to_stream>
--sout=#std{access=udp,mux=ts,dst=<destination_ip>:8200} --no-sout-audio

With RTP, I'm using a version of the Gstreamer RTP example from
es/rtp/server-v4l2-H264-alsasrc-PCMA.sh, which I modified to use a
filesrc instead of a v4lsrc (see attached).  The script can be invoked
with the following syntax:

  ./server-file-H264.sh <file_to_stream> <destination_ip>

Can you share this pipeline?  I'd like to try it on my end.
