Use WebRTC with WebWorker

Question

I am interested in to use webrtc with webworker. Is it possible?

I tried it but it did not work because it did not find the "window"

Answer 1

According to the specifications [1, 2], navigator.mediaDevices and RTCPeerConnection are not defined for web workers, so WebRTC shouldn't be available on web workers for now.

For [1], navigator.mediaDevices attribute is defined on Navigator interface for window, but not on WorkerNavigator interface for web worker.

For [2], RTCPeerConnection interface is exposed to window ([Exposed=Window]), but not to web worker ([Exposed=Worker]).

Answer 2

The worker does not need to handle the webrtc connection it gets handeled outside the render process anyway and connected via MOJO:IPC internal so you can simply target from the render process a sharedArrayBuffer if your working in a secure context. Then you create a worker passing it the same arrayBuffer that u use to write out the WebRTC data.

Also wasm by design works in a worker on sharedMemory that means as soon as you do any processing in wasm your working in a worker.

It makes no sense to move WebRTC into a webworker as the final goal is to not copy data between the render process and what ever sends it via remote.

to eneable low latency copying data would destroy that.
