Note, however, that although this will prevent any future clients from accessing this stream, it will not stop any streaming that's current ongoing for this "ServerMediaSession". If you want to do that, you would need to delete the "RTSPServer::RTSPClientSession" object for each currently active client. (This has the same effect as the client having done a RTSP "TEARDOWN".)</div><br><br><div apple-content-edited="true">
