What is “v4l2rtspserver”?  We have no software with that name.  We support only the (latest version of the) software that’s described at 
	http://live555.com/liveMedia/
and downloaded from our own web server.

Note that, to stream via multicast, your “RTSPServer” must *not* use a “OnDemandServerMediaSubsession” subclass; that is used only to stream via unicast.  Instead, you should use a “PassiveServerMediaSubsession”.

There are several examples of this in the “testProgs” directory.  Note the demo applications named “test*Streamer”.  These applications stream via multicast, and include a (sometimes optional) RTSP server that uses a “PassiveServerMediaSubsession” to provide RTSP access to the stream.
