It looks like you haven't even started playing the stream - i.e., you've never
even called "startPlaying()" on your "H264VideoRTPSink" object!
Note, however, that if you're using a RTP server, then this should all be
happening automatically (once you get the first re quest from a RTSP
client). Make sure that you're implementing the virtual functions
"createNewStreamSource()" and "createNewRTPSink()" properly.
Another thing you can do - because you know the SPS/PPS NAL units in advance -
is pass them as parameters to one of the alternative forms of
"H264VideoRTPSink::createNew()", which you call from your "createNewRTPSink()"
virtual function implementation. (See "liveMedia/include/H264VideoRTPSink.hh")
