grabFrame cannot be cancelled

[stephanreiter]

I'm using an ImageCapture and grabFrame to retrieve frames from a video stream. grabFrame returns a promise that I need to await to get a frame.

I don't see a way to cancel the grabFrame operation such that the promise is rejected. In response to a user action, I'd like to immediately abandon awaiting and not having it sit around until the next video frame (which may, in a bad situation, never come).

Could this be accomplished by allowing me to dispose the ImageCapture, which would in turn cancel all ongoing operations and reject associated promises?

Sounds like a mission for AbortController?
