Multicasting from two network interfaces.

Hi,
I'm using VLC to multicast two different streams. I need each stream to go out a different network interface.
Is this possible?
I have tried using --iface <ip address> but this doesn't seem to work...
The stream always uses the same card!
Could this be a problem with the card? No multicast support?
Thanks,
Fred.

The proper way to do this would be to change your routing tables.

And how to do this in win xp?[/url]

If one of your Ethernet NICs has an address of 172.120.20.3, and the other one has an address of 192.168.2.3, in Windows 2000/XP I would open a DOS prompt and enter:
route -p ADD 239.239.0.0 MASK 255.255.0.0 192.168.2.3 METRIC 1 IF 192.168.2.3
(I could be wrong on the precise syntax -- may not need the last IF part of it)
What this does is tell the PC to add a persistent route (saved between reboots), where it shovels any 239.239.x.y address out the 192.168.2.3 interface of the PC.
Still not working :(

To access the multicast stream (the thing being sent on an address of 220.0.x.x to 239.255.x.x):
Launch VLC on the lient.
Select File -- Open Network Stream
Select the 2nd UDP option, the one that has an "Address" field -- type the multicast address into it.
vlc

YEs I did this (friend on lan multicasting on 239.192.1.1)
and i still get nothing
Another problem occured I remove route path
route delete ....
and now i cannot add anything to route, when i type route -p ADD... or route ADD.... the route program runs without any params...

Any chance that your friend has two NICs (Ethernet cards)? If he does, it might be sending the multicast out the wrong NIC.
Are you able to get a point-to-point UDP stream OK? Have the Server do a UDP to your PC's IP address, then on your PC run the Open Network Stream, select the first UDP choice (the one with no Address field), see if you're able to get the directed (unicast) stream.

We have lan and about 100users on it
I multicast, and anybody has no problem to connect to my stream
He multicast on a different adress and other people can join to him
but i cant join neither to my or his stream :/

It almost sounds like your OS has been set to disregard (ignore) receiving multicast. At least in Windows 2000 you actually can manage to do that -- you can tell it to ignore all multicast, to only permit TX of multicast, or to both TX and RX multicast.
The other thing would be to install a fresh copy of VLC. Are you getting any errors?
-Open VLC
-Select View -- Messages
-Have your friend start a multicast. In my case, on WinXP, just for test I open a second set of VLC and start a multicast of a file. I set the file for UDP on IP 239.10.20.30, the default port (1234)
-I then go to the first copy of VLC, my client, and select File -- Open Network Stream. I select the second UDP option, the one where you plug in the IP, and give it 239.10.20.30. It quickly opens the playback window, and the following is what the Message window showed:

The above is a "healthy" Message window, VLC opening the multicast connection, seeing what the video is, playing it. What do you get in your Message window, when you try to open the connection to display the multicast?

Im using winxp too
i do multicast locally at 239.192.10.1
this is the message from client
main debug: adding playlist item `udp://@239.192.10.1' ( udp://@239.192.10.1 )

ipv4 debug: IP_ADD_MEMBERSHIP multicast request

so what do you think is the problem?

...and when i try to join to my friends stream the messages are the same, and same are too when he is not multicasting...

Maybe..
i have installed virtual mashine (vmware) and this add two networks adapters for virt. mash. could be this the problem?
in v.m. i used bridged network...

LOL ...
problem solved
problem is with vmware....
VMware and VLC player on XP multicast problem ...

I'm having this same problem. Will you post the solution? Thanks
VMWare

I have had VMWare installed on both a Linux system and a Windows system.
VMware is breaking VLC so that you can't connect to multicast streams (haven't tried unicast streams).
I never investigated why, but removing VMWare solved the problem, I rather have VLC working than VMWare, so problem solved for me
If I remember correct a workaround is to disable the virtual NICs installed by VMWare in Windows.
Under Linux do a "/etc/init.d/vmware stop"

The virtual NIC's of Vmware can't handle multicast or do this incorrectly.

not sure if this would help but you can try it if you want:
Code: Select all
vlc -miface=<your_ip> (whatever other options)
I'm not sure if the parameter is -miface or -iface so try the other if one doesn't work.

Turns out the commands above apply to receiving multicast, not sending it. I have the same problem as this thread, two NICs but need to specify which NIC to send the multicast stream out on. Is there a command to specify which network interface to use? I've tried
but that doesn't work. I can't set the route because I am on linux and don't have permissions.
Anyone got a solution for this?
