OK, so you will need to write a new class that acts as a data 'duplicator' - i.e., taking one input, but generating several outputs. Each output would be fed to a separate "RTPSink" object (each with its own "groupsock"). You would call "startPlaying()" on each of these "RTPSink"s. -- Ross Finlayson Live Networks, Inc. http://www.live555.com/ _______________________________________________ live-devel mailing list live-devel@lists.live555.com http://lists.live555.com/mailman/listinfo/live-devel
