Advanced options: Specifying the multicast network interface(s)

liveCaster and playRTPMPEG have two additional, optional command-line arguments - "-si <IP-address>" and "-ri <IP-address>" - that can be used to specify the (unicast) IP address of the multicast sending and receiving interfaces, respectively.

Most users will not need these options. (Don't use them if you don't know what you're doing :-) These options can be useful on dual-interface systems where incoming and outgoing multicast use different interfaces, and/or on systems where a default multicast route has not been set.
