Description

While under Linux the parameter "multicast-iface" does its work, under windows is ignored, indeed "udpsink" and "udpsrc" bind using the default network card instead of the one indicated.

I confirmed the problem receiving a multicast stream on a network card and trying to transmit it on another network card, with Wireshark I see the stream transmitted on the first card.
