Canceling a video frame callback

This example shows how to use cancelVideoFrameCallback() to cancel a previously-registered video frame callback.

js
const updateCanvas = (now, metadata) => {
  // Do something with the frame

  // ...

  // Re-register the callback to run on the next frame
  // It's important to update the videoCallbackId on each iteration
  // so you can cancel the callback successfully
  videoCallbackId = video.requestVideoFrameCallback(updateCanvas);
};

// Initial registration of the callback to run on the first frame
let videoCallbackId = video.requestVideoFrameCallback(updateCanvas);

// ...

// Cancel video frame callback using the latest videoCallbackId
video.cancelVideoFrameCallback(videoCallbackId);
