RE: Media Capture Stream with Worker

Got it. It will be nice if ImageBitMap has an interface to get the raw ImageData. And then combine with Image Capture(https://w3c.github.io/mediacapture-image/) APIs.

You don't have to render the data to the canvas to process it. Just use it as an API.
AFAIK it's the only way.
