Peer 2 peer video streaming over internet

[veryevil]

Hi, I'm wondering if it's possible to get video streaming working between 2 computers without a server on the net in the middle handling the video. Happy for a server to do negotiation but don't what video going up to server and back down.

My thought is that firewalls on standard routers will not allow the incoming connection so I don't think it's possible. Hoping this is possible without any router config or ports opening.

Any suggestions I can go research?

Thanks

Microsoft Teams does that as long as there are only 2 participants. Both connect to the server first and then a connection is set up between the clients. When there are more than 2 participants the streams go to the server first and are distributed from there.

Hi, I'm more interested in how to go about this not apps that do. Sorry I wasn't clear.

Want to put this into a custom application running on 2 Linux machines

Thanks

Yes, I got the idea that you were not looking for an App, but I wanted to point out that it is indeed possible. However, if you don't want to use an external server for the initial contact you might have to open some ports in the firewall.

NATTT doesn't come up with anything relevant that I can see?

WebRTC is the tech for this, https://webrtc.org/ built into the major browsers.

Open source example of this is https://obs.ninja/
