How to get a stream with ffmpeg through a specific eth(interface)

Question

I have a server with 2 interfaces, eth0 and eth1. eth0 -> conected to Managment Switch eth1 -> conectated to Video Switch

I would like to get a multicast with ffmpeg through eth1.

Is there some command like ffmpeg eth1 -i udp://236.1.1.1:5000 ? I also need to know how to send the multicast through the same interface like ffmpeg eth1 udp://236.1.1.1:5000 eth1 -f mpegts udp://239.1.1.1:5000?pkt_size=188

Thanks in advance.

Solution

udp://236.1.1.1:5000?pkt_size=188&localaddr=192.168.0.20

Where are you getting 192.168.0.20 from? Please explain.

Sorry for unclearity, it is the IP address of the interface you would like to sent multicast traffic via

This worked for me -- see the documentation here: ffmpeg.org/ffmpeg-protocols.html#udp You can find your network interface's IP address via ifconfig
