I want to do it so that the four of us can watch the HoloLens2 video. #817

First of all, I'm sorry that I'm using a translator. I don't have any English skills.

The final appearance I think is that I want to send a HoloLens video/voice to four web browser users.

I succeeded in 1:1 communication, but when I try to connect from another web browser, the error below appears. Please tell me a solution or a solution.

WebRTC is a peer-to-peer 1:1 technology. You cannot do that.

If you really want to connect 4 people, you need to setup a media server, and connect all 4 clients to it. See for example Janus (Disclaimer: I/Microsoft has no affiliation with Jannus; I just know some people had success with it. Other servers should work too, since WebRTC is standardized).

@djee-ms Thank you so much for your kind and quick response.

I looked it up and told WebRTC that the SFU method supports 1:N. I don't think this is possible either.

djee-ms commented 3 years ago

SFU and MTU require a media server. They're technologies that build on top of WebRTC; they're not part of the WebRTC standard itself.

The Peer to Peer (Mesh) method allows two to three people to exchange data without a server, but can this be applied?

djee-ms commented 3 years ago

The mesh method uses 1 peer connection per pair of peers. So here you have 3 peer connections in your example. You can use that, but that scales very poorly. However that doesn't require any media server, true.

Thank you so much for your kind reply.

It was a lot of reference and help.

I will end the issue.
