By default, this parameter is 6970, which means that the server will try {6970,6971}, then {6972,6973}, etc., until it finds a port number pair that isn't already used.</div><div><br></div><div>So, if you want to change this parameter, you would do so in your subclass(es) of "OnDemandServerMediaSubsession" (when their constructor calls the "OnDemandServerMediaSubsession" constructor).</div><br><br><div apple-content-edited="true">
