Hey @mickel8! This is a very interesting collection of repos, and it has my wheels spinning. 🤔

Background

I am using WebRTC data channels for low-latency transfer between clients, and I'm wondering if the ex_webrtc package would have a role to play in my application. My approach has been to build a phx-hook and use a LiveView as a signaling server. This works quite well.

I'm in the process of de-coupling and refactoring the prototype code. This includes building a WebRTC LiveComponent for my app.

Questions

After poking around the Elixir WebRTC documentation, I appreciate the structure of the modules. What I don't quite get yet is how I'd use the package.

• Would this be used to establish WebRTC connections between servers?
• Does it support client-server communication - essentially as a WebSocket alternative for some purposes?
• All/none of the above?

Excellent work! Can't wait to see more documentation and development.

ICE negotiation has been working well on my prototype that uses a LiveView as a signaling server. The app is hosted on Fly.

They do have some documentation for UDP, but there's no mention of ICE negotiation in the docs. Were you doing ICE over LV or something else?

[mickel8]

So you are able to establish stable UDP ICE connection on Fly? We were using Web Sockets for signaling. Also, this was a couple of months ago so maybe something had changed

[type1fool]

Actually, yeah, I have seen some instability. I assumed I had written some buggy WebRTC code, though. It's also been a couple months now since I was working on and testing that part of the application.

Once the WebRTC connections are established, the peers are connected directly via UDP, so I am unsure if/how Fly would have any impact. For now, I'm using an external vendor's STUN service and disallowing TURN. Have you deployed the same code to another PaaS with better success?

Nope, we instead switched to Hetzner where we have a bare machine 🙂

Hey @mickel8 thank you for WebRTC in Elixir,
context: I run a YouTube channel and trying to build feature like Google meet in LiveView for YouTube tutorial WebRTC in LiveView still working on it.

How to disable these logs?

[mickel8]

Hi @ambareesha7, nice to hear that!

These are debug logs from our ex_ice library. You either have to change your log level from debug to info or disable logs from ExICE modules or ex_ice app.
