Hi all,

I've installed the latest Debian (unstable) packaged version of vlc under a 2.6.5 kernel. And I'm trying to make a multicast broadcast by typing the following command:

vlc -vvv videofile.mpg --iface-addr 199.99.99.171 --sout udp:@225.0.1.2:5001

But nothing appens because of this error:

...

I'm wondering if I missed any network options in my kernel configuration or anything else. But the other thing is that I am able to open a multicast stream and watch it in my computer... So I'm a bit lost.

Can anyone help me to solve this problem?

Not sure, but you might try deleting the "@", so that it reads:
--sout udp:225.0.1.2:5001

When you look at the How-To, @ seems to only be used for the receive side, not the TX side.

Thanks for your support but it does not change anything, I've seen lots of time people having this problem... but never real issues...

Do you have multicast support in your kernel?

Does your network configuration support UDP ?

yes it does. IP multcasting option is enabled in my kernel and I can read a multicast stream so I am able tu support UDP...
