Bringing this up as the spec touches on bindings with canvas.

Now that there is [1] offscreen canvas, it would be worth looking into how this spec integrates with that.

This issue had an associated resolution in WebRTC February 2024 meeting – 20 February 2024 (captureStream on OffscreenCanvas on):

RESOLUTION: Supporting captureStream on OffscreenCanvas is reasonable but low priority

It seems that creating a VideoTrackGenerator from an OffscreenCanvas and using it as a MediaStreamTrack might replace the need for the captureStream() method for OffscreenCanvas, doesn't it?

The reverse is also holds: captureStream() from an OffscreenCanvas might replace the need for VideoTrackGenerator.
