    Ok Thanks, It's not the answer I wanted but It's what I expected.<br>
    <br>
    I guess even if I could configure the server in this way the client
    support might not be great anyway.<br>

        You can’t.  The server (specifically, the
        “ServerMediaSubsession” object, identified by ‘stream name’)
        specifies the characteristics of the stream (including whether
        it’s unicast or multicast).</div>

        Yes, this is the way to do it (i.e., using different stream
        names, with a “PassiveServerMediaSubsession” for multicast, and
        a “OnDemandServerMediaSubsession” (subclass) for unicast).  Note
        that you can use a “StreamReplicator” to make two copies of your
        live source; delivering one copy to
        the “PassiveServerMediaSubsession”, and the other copy to
        your “OnDemandServerMediaSubsession” (subclass, with
        “reuseFirstSource” True).</div>
