Hi, I have tried in Windows XP SP2 VLC 0.8.5 Final release this:

vlc -vvv udp://@235.100.100.100:1234

to recieve a multicast streaming froma a dedicated streming server hardware. Everything works great.

Now using FEDORA CORE 5, VLC 0.8.5.
( I think all needed modules are properly configured (vlc -l))

I have tried unicast vlc -vvv udp://@10.1.1.110:1234 using vlc to make the streaming. It works OK.

But when trying:

Code: Select all

vlc -vvv udp://@235.100.100.100:1234

I'm always getting:

Code: Select all

I thought that it could be a network problem:
But using Ethereal I can see multicast packet in the client machine.
Client routing table:

The streaming server is on 192.168.100.0 network.

Please, can anyone help me?

first : set the correct multicast address 224.0.0.0

second : the client only need to set 224.0.0.0

make sure the server and client in the same sub network

if not ,you may set the router

I have the same problem. Two computers, one under control of XP SP2, the second FC5. XP SP2 shows, and FC5 will show a fragment and through what that time all stops. But if to disconnect Firewall on FC5 that all shows. A problem in rules Firewall.
