[Feature]: IPC streaming to the browser

Describe the feature/enhancement you need

I would like to stream data like video frames from the process which manage webview2 to to the browser directly using IPC methods for high performance

The scenario/use case where you would use this feature

Video frames, Audio

How important is this request to you?

Critical. My app's basic functions wouldn't work without it.

Suggested implementation

A way to add listener in webview2 side (and in the end in JS)
and a way to stream into that from outside, cross platform.

What does your app do? Is there a pending deadline for this request?

My dream app would be RTSP viewer app based on webview2 which decode the frames in Python / Rust and stream it directly to the DOM
