Hello
Newbie question about IGMP-messages and VLC. I have switch and two laptops. When I connect two laptops to switch and use first stream DVD movie to udp://224.0.0.1:1234 ja I use second laptop to receive udp://224.0.0.1:1234. Stream propagates like a broadcast. On switch "IGMP snooping" is off. Everything works ok, but there's unneccessary 9Mbit/s port utilization on those ports who do not want to see movie.
After that I configure switch and turn "IGMP-snooping" option on. That should configure switch behavior so that stream is sent only to ports who are joined to multicast group. Ok that seems to work, stream doesn't propagate anymore to ports who are not joined to IGMP-group.
Problem is that VLC seems to be passive listener, it doesn't send any "Hey I want to join 224.0.0.1" messages.
Does (or should) VLC send IGMP messages?
