After uploading the video, I can get any frame in it as the cover. Is there any way to do it?

var captureImage = function() {
var canvas = document.createElement("canvas");
canvas.width = video.videoWidth * scale;
canvas.height = video.videoHeight * scale;
canvas.getContext('2d').drawImage(video, 0, 0, canvas.width, canvas.height);
var img = document.createElement("img");
img.src = canvas.toDataURL("image/png");
output.appendChild(img);
};
initialize();
})();

canvas.getContext('2d').drawImage(video,
0, 0, canvas.width, canvas.height), use the above method to refer to https://developer.mozilla.org.. .
