If I self host some kind of private video chat service, is the video data transferred direct from connected peer to peer? Does it go through the self hosted service instance? Or does that depend on which video server is used?

    Jitsi Meet can be self-hosted. The data will go through your server, but end-to-end encryption can be used.

    Another option is Wirow. Again, data goes through the servers.

    I do not think if there are any peer-to-peer video chat applications. If there were, why would there be a need for self-hosting a server?

      Jitsi Meet it’s usually p2p for calls between two persons. As soon as a third person joins, the meeting gets routed through the server. You can see this by a slight delay happening when person 3 joins. It won’t happen again for every additional person joining

    How many participants in your video call?

    If it’s 1 on 1, you want direct connections.

    If it’s a conference of 30 people, you don’t want direct connections, because everybody’s typical plastic home wifi router is very unable to handle 30 incoming plus 30 outgoing video streams at once.

    Usually it’s p2p, there’s a moment while initiating the connection where some server is needed for STUN/TURN (i.e. NAT traversal).

    I assume some service may have a fallback for server broadcast instead of p2p, but none that I know of do such a thing.

      Thanks. I’m just curious how much bandwidth would be consumed by the self hosted server if all video traffic is routed through it. If the video traffic is p2p then the self hosted server would be cheaper to maintain.

        Of course check the implementation you end up using if it truly is p2p. Also you can analyze the bandwidth of services on your server, which may be useful in your case.

    Self hosted only fans? I want to put on shows for myself to help me save money easier.

    I need to stop shit posting in genuine communities.

    Of course it depends on what software you are using.

    Though as a rule of thumb, peers try to connect directly. That’s not always possible due to firewalls/NATs, so often TURN servers are used as intermediary.

    That depends entirely on the protocol you’re using… That’s like asking if HTTP works the same way as vittorrent because they both are used to transfer files.

  • @YurkshireLad Depends on the video chat service and on the infrastructure of the participants.

    Most browser based video chat services use WebRTC which usually uses peer to peer if NAT hole punching works - but that depends on the ISP routers.
