That's odd. Perhaps the >0 value returned by "select()" is for the
(TCP) RTSP socket, and not for any of the (UDP) RTP sockets? If so,
then this would suggest that you are not receiving any RTP packets at
all (which would explain why
"MultiFramedRTPSource::networkReadHandler()" is never called).
All I can suggest at this stage is noting the socket number(s) that
are passed to the calls to "turnOnNetworkReadHandling()" (in
"RTPInterface.cpp" and "RTSPClient.cpp"), and comparing those to the
socket numbers that are indicated as being 'readable' following the
call to "select()". I suspect you'll find that you're not receiving
RTP packets, for some reason (perhaps a bug in your OS???).
In any case, there's no point in looking at the VLC code here,
because the problem appears to be occurring at a much lower level.
