udp multicast problem?

[djstava]

Socket error occurs when I receive the udp multicast stream,and client can connect to the server.I found that the client do not send the IGMP by capture the packets,server rejects the client's connection that client cannot add to the multicast user list. How can I figure it out?
Thanks.

Your problem does not make much sense. A client does not connect to a server when multicast streaming.

mplayer can play now but vlc still not.

I construct an environment using vlc(both server and client) by myself,multicast ip:239.255.0.1,port:8000.Strange is that on Windows XP(v1.0.5),everything is OK and on ubuntu lynx vlc(v1.0.6) is not working,by the way mplayer works well.What's wrong?

[Rémi Denis-Courmont]

That would be udp://@239.255.1.9:8001

[djstava]

Thanks,it works well.
