写一个方法，实现使用canvas播放视频？

canvas draw by argb

// height、height 代表视频宽和高function drawArgb(argb, width, height, ctx) {        const imageData = ctx.createImageData(width, height);        imageData.data.set(realdata);        ctx.putImageData(imageData, 0, 0, 0, 0, width, height);}

canvas draw by video

    function drawVideo(srcvideo,  width, height, ctx) {        ctx.drawImage(srcvideo, 0, 0, width, height)        requestAnimationframe(() => { playCanvas(srcvideo,  width, height, ctx)        })    }

注：没有写fps控制
