If you have already been able to stream raw video and raw audio over RTP, I’m not sure why you would then want to package and stream them in a Transport Stream (something that increases latency and network bandwidth).  But anyway…

At first glance, this looks OK, except for:

Because you’re outputting the H.265 NAL units into a Transport Stream (rather than into RTP packets), the third parameter (“includeStartCodeInOutput”) to "H265VideoStreamDiscreteFramer::createNew()” should be True, not False.  (Note that the input NAL units must still *not* have a preceding ’start code’ (00000001); however, they need to be present in the Transport Stream, and setting the “includeStartCodeInOutput” parameter to True will do this.)

If this doesn’t fix your problem, then I suggest starting with our “testH265VideoToTransportStream” demo application (in the “testProgs” directory).  Make sure that this works OK for you (using a H.265 Elementary Stream video file from your camera).
