Since now we can control all 3 streams independently, wouldn't it be cool if we could assign certain NIC to the stream number?

But why, you might ask?

Simple. Most of the streaming platforms have primary and backup RTMP URL. If first fails, stream will not fail for users, but backup will be used. So the use case would be following (lets take Youtube for example)

Stream 1:
rtmp://a.rtmp.youtube.com/live2
NIC #1 - venue network connection

Stream 2:
rtmp://b.rtmp.youtube.com/live2?backup=1
NIC #2 - our own 4G network / separate network connection

If venue network fails for some reason (for example power outage), our stream would not fail for users, since we have independent power supply.

And yes, true backup would be second PC which streams to backup URL from backup network.

In light of thread https://forums.vmix.com/...aspx?g=posts&t=15942 NIC selection should also be available for web controller.


This will also let us use two connections on the single machine, for example vMix uses only NIC #1 for streaming, but our other network needs (stats, recorded content download/upload, live monitoring etc) will be taken care of NIC #2.
