Interacting with other elements Video elements can interact with other elements like canvas to provide a completely new experience. Canvas' drawImage lets you grab a single frame from the video element, and draw it within the canvas. Embedded Image function grabScreenshot() { ctx.drawImage(video, 0, 0, videoWidth, videoHeight); var img = new Image(); img.src = canvas.toDataURL("image/png"); img.width = 120; ssContainer.appendChild(img); }

Monitoring the progress of a read One of the nice things that we get for free when using async event handling is the ability to monitor the progress of the file read; useful for large files, catching errors, and figuring out when a read is complete. The onloadstart and onprogress events can be used to monitor the progress of a read. The example below demonstrates displaying a progress bar to monitor the status of a read. To see the progress indicator in action, try a large file or one from a remote drive.
