Returning to the stdout->stdin approach: the same SPS/PPS problem is
present here too. We have the H264 SIP RTP subsession without any sprops,
so call to subsession->fmtp_spropparametersets() is useless in playSIP :
...
fileSink = H264VideoFileSink::(outFileName,
subsession->fmtp_spropparametersets(),
fileSinkBufferSize, oneFilePerFrame);
subsession->sink = fileSink;
subsession->sink->startPlaying(*(subsession->readSource()),
subsessionAfterPlaying,
subsession);
...
How to make the subsession->fmtp_spropparametersets() returns something
usefull in playSIP for SIP H264 RTP ?
