I've been streaming this way for a while now.

Yes, you can dual stream.

- I do this using livepush.io. So one stream out to livepush and they push to multiple services. - However you could run multiple instances of this container and have each stream to a different service. For example one container being the main streaming setup that streams to Twitch but also has NDI or Teleport output that can then be ingested via a second instance of this container that streams to YouTube.

Using this is KVM is technically possible but you'd lose a load of the benefits of running in a container, such as hardware acceleration and seamless integration with your host.

Can ChromeOS running Podman and Distrobox? If so, it should work fine.
