 |
|
Hello all!
I have strange problems with vlc and multicast stream, it sometimes works,sometimes not. on eth0 is two multicast streams with adress 224.1.1.1:11111 and 224.1.1.2:11111, eth1 outgoing interface:
There is one gentoo box with 2 net cards:
/etc/conf.d/net:
| Code: |
config_eth1=( "85.*.*.123/27" )
routes_eth1=( "default via 85.*.*.97" )
config_eth0=( "null" )
|
/etc/conf.d/local.start:
| Code: |
echo "0" > /proc/sys/net/ipv4/conf/eth1/rp_filter
route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0
|
I have compiled multicast support in kernel
/usr/src/linux/.config:
| Code: |
CONFIG_IP_MULTICAST=y
|
I run vlc from console with parametrs:
| Code: |
vlc -vvv udp://@224.1.1.1:11111
|
vlc console log:
| Code: |

Sometimes i got asci picture from stream,sometimes it says pre buffering, i try stable vlc and alpha vlc from portage,but without suscess, i use wireshark to see trafic on switch who connected to eth0, there is multicast group join request and udp streams, i can open streams using vlc on windows Xp connected to this network.
if vlc is launched and says prebufering iftop shows, 5,78Mbp traffic from: 80.*.*.66 to 224.1.1.1
Need help! |
