“ServerMediaSubsession” is an abstract base class. It is used by a RTSP server to describe each piece of media that it streams. “OnDemandServerMediaSubsession” is a (concrete) subclass of “ServerMediaSubsession”. It is used to stream a particular piece of media to one or more RTSP clients, each via unicast RTP. > 2. What is different between RTPSink and SimpleRTPSink classes? “RTPSink” is an abstract base class, used to represent a destination (unicast or multicast) for RTP streaming. “SimpleRTPSink” is a (concrete) subclass of “RTPSink”. It is used to implement many simple RTP payload formats (that do not include any media-specific headers or fragmentation). > 3. Can I play/stream a wav file with g729 codec, which testProgram does this > ? (so far I am successful with g711 (alaw/uLaw) and AMR ) *In principle* you could use the “LIVE555 Media Server” (for streaming via unicast), or “testWAVAudioStreamer” (for streaming via multicast). *However*, our code currently doesn’t support streaming from a G.729 WAV file - in part because I’ve never seen such a file. So, if you could point me at such a file (put it on a publicly-accessible web server, and send me the URL), I’ll download it and see if our code can be updated to stream files like this. > 4. Could you please address me to the class where I can record incoming RTP > stream in to a wav file format? We currently do not support recording into a WAV file. However, if you run the “openRTSP” RTSP client application - http://www.live555.com/openRTSP/ - you will get a ‘raw’ audio file. If you were to ‘prepend’ an appropriate WAV audio header to this file, you should get a WAV file that you can play.
