It's the server that decides whether or not to stream via multicast.  (The 
SDP description returned by the server - in response to a "DESCRIBE" - 
differs depending on whether the stream is multicast or unicast.)

If you want your server to stream either multicast or unicast, then you can 
do this using two different stream names, and add two different 
"ServerMediaSession" objects to the server.  (Thus, the multicast stream 
will have a different URL from the unicast stream.)  For multicast, add a 
"PassiveServerMediaSubsession" to the "ServerMediaSession"; for unicast, 
add an appropriate "OnDemandServerMediaSubsession" subclass.  See the 
testProgs for details.
