Hi all,

I'm trying to make a multicast rtp stream. There is nothing wrong with the firewalls because I tried to use a UDP multicast stream and it worked fine (server started with the command: vlc -vvv eagle.mpeg --sout udp:255.10.10.10:1234 --ttl 12). A unicast RTP stream also works fine. But when i tried to make an RTP multicast stream (server started with the command: vlc -vvv eagle.mpeg --sout '#rtp{dst=255.10.10.10,port=5004,mux=ts}' ) it failed. The computer is sending IGMP join messages. I'm using OSPF, PIM and IGMP on debian systems.

Thanks,

255.10.10.10 is not a valid as a multicast IP address.

What multicast address should I use then?

You should use a multicast address.
