Because you are trying to stream MPEG Transport Stream data over RTP, you
should *not* be using a “H264VideoRTPSink”, because that is used only to stream
raw H.264 video. In your case, you don’t have access to the raw H.264 video,
because we don’t provide a mechanism for demultiplexing the input Transport
Stream data; instead, you need to re-stream the Transport Stream itself. You
do that using a “SimpleRTPSink”.
To do this, do the following:
1/ Use a “BasicUDPSource” to receive the raw-UDP Transport Stream.
2/ Feed this to a “MPEG2TransportStreamFramer” (to generate proper
'presentation time’s for the Transport Stream packets).
3/ Feed that to a “SimpleRTPSink”, which is created as follows:
SimpleRTPSink::createNew(env, rtpGroupsock, 33, 90000, "video", "MP2T",
1, True, False /*no 'M' bit*/);
HOWEVER, if you are doing this inside of a RTSP server, then you don’t need to
write any new code to do this. Instead, just add a
“MPEG2TransportUDPServerMediaSubsession” object to your RTSP server. Our
“RTSPServer” and “MPEG2TransportUDPServerMediaSubsession” code does all the
work for you.
For an illustration of this, see the “testOnDemandRTSPServer” demo application
(a RTSP server); in particular, lines 404-430 of
“testProgs/testOnDemandRTSPServer.cpp”.
