-BNC can output the stream related to the above specified 'Mountpoint' on your local host through a TCP/IP port. Enter a port number to activate this function. The stream contents remains untouched. BNC does not decode or reformat the data. This option does not work when specifying keyword 'ALL' as 'Mountpoint' because you can't apply this option to all configured streams at once but only to one specific stream.
