So, situation first:

System network layout:
eth0 - internet
eth1 - multicast source directly connected(no other device between) to this NIC
eth2 - not used by system(remote console LAN)


Kernel has CONFIG_IP_MULTICAST enabled

And the problem...
When I run vlc -vvv rtp://ip:5004, it does not play the stream. The entry in /proc/net/igmp appears
Firewall is off(accept all). Route is correct
Code:
224.0.0.0       0.0.0.0         240.0.0.0       U     0      0        0 eth1


Output from vlc says - rtp://givenip:5004 successfully opened, but 'stats' gives only zeroes

Code:

status change: ( audio volume: 256 )
status change: ( play state: 3 )

| input bytes read :        0 KiB
| input bitrate    :        0 kb/s
| demux bytes read :        0 KiB
| demux bitrate    :        0 kb/s
| demux corrupted  :        0
| discontinuities  :        0


Opening any local file(some .avi) works without problems.
Just to verify multicast source, I connected a windows machine with vlc - works good

So I think, I am still missing something, either in the kernel or some use flag in vlc, some proc entry...whatever.
Video in RTP is mpeg2

Enabled vlc use flags: ffmpeg gcrypt httpd mmx mpeg ncurses rtsp sse stream x264 (system has no X, it will serve as stream forwarder)

Any help is welcome
