OK, this is completely different to what you were asking about before. You don't need to 'receive RTP packets' at all. You can do what you want to do by using the new "StreamReplicator" class (see the "testReplicator" demo application for hints on how to use this). First, take the incoming H.264 NAL unit stream from your RTSP client (i.e., from "subsession->readSource()") and feed it into a new "StreamReplicator" object. Then create two 'replica' streams (using "createStreamReplica()") from the "StreamReplicator" object. Use one replica for your 'mp4' file output (i.e., a "QuickTimeFileSink"). Use the other replica for streaming (using a "H264VideoStreamDiscreteFramer" fed into a "H264VideoRTPSink"). Call "startPlaying()" on each of these 'sink' objects before entering the event loop.
