The problem here is that the output from "H264VideoRTPSource" is a sequence of
raw H.264 NAL units - i.e., without 'start code's.

This *should* work, with one modification: You will need to add a 'start code'
(i.e., 0x00 0x00 0x00 0x01) before each NAL unit that comes out of the
"H264VideoRTPSource". You will need to do this - using a separate filter class
(that you would write) - before you feed the output into a
"MPEG2TransportStreamFromESSource".
Before doing this, though, I suggest that you do
H264VideoRTPSource -> H264VideoFileSink (*not* just a "FileSink")
and then try running the (original, unmodified)
"testH264VideoToTransportStream" application to generate a Transport Stream.
(Note that "H264VideoFileSink" adds 'start codes' before each NAL unit.)
