You don't.  "testOnDemandRTSPServer" is for unicast streaming only.

To stream via multicast, use the appropriate "test*Streamer" application as 
a model.

This is caused by a 'misfeature' (really, a bug) in the LIVE.COM RTSP 
client code (which VLC uses).  It responds to *any* incoming RTCP "BYE" 
packet by tearing down the RTSP connection.  Instead, it should really be 
responding only to RTCP "BYE" packets that come from the server - not from 
other multicast clients.

Until this is fixed, I suggest that you shut down VLC by killing it with 
the Task Manager (if you're running Windows), or by "kill -9" (if you're 
running Unix).  This will stop VLC without also causing it to send out a 
multicast RTCP "BYE" packet.
