Get frame(s) from Video stream

This is driving me nuts. Can someone please show me how to get the frames from a video stream? I get the stream using the example, see below, and that works well. But how do I go about getting each frame from that stream? Any help or tip is very very very welcome!

```
navigator.mediaDevices.getUserMedia(constraints)
.then((stream) => {
console.log('getUserMedia.stream', stream);
console.log('getUserMedia.stream.getTracks', stream.getTracks());
console.log("Im streaming!!", stream);
var video = document.querySelector('video');
console.log("video element", video);
video.srcObject = stream;
video.onloadedmetadata = (e) => {
console.log("stream start");
video.play();
};
}).catch((err) => {
console.log('getUserMedia.error', err, err.stack);
});
}

```

Start with the navigator.mediaDevices.getUserMedia entry point and the video element shown in the issue. First determine whether the requested frame access belongs in the plugin or needs usage documentation; the issue is complete only once the supported way to obtain individual frames is explicitly defined.
