Could you say a bit more about your setup Alex? cc @boundless-energy-78552

I'm using cloud setup at wss://ansoftware.livekit.cloud and trying to connect with RustSDK and simple_room. Below are the logs

Hey @icy-shampoo-64781, how are you publishing videos? The Rust SDK doesn't support publishing yet (We're actively working on it). If you want to receive videos on your Rust app. You can either use the livekit-cli or use the JS example app to publish videos

OK, that explains what I see. Thank you.

There are the Swift and the Flutter SDK

Here’s (probably) the fastest path Alex: https://docs.livekit.io/getting-started/cli-setup/#simulating-another-publisher

Thanks, but if I want to publish live video from camera I probably should take the Flutter route?

Yes, if you want to use your webcam, it is a good way

The fastest way to do that is probably to use this (if you’re just trying to test)? https://example.livekit.io/

Yes, I saw your cool React components and I already ran Unity WebGL example but I need to run a native app.
