Just like when we discussed animation in the previous chapters, a video placed on HTML5 Canvas using drawImage() will not update itself. You need to call drawImage() in some sort of loop to continually update the image with new data from the playing video in the HTML page (hidden or not). Canvas provides a drawImage function which takes input the Video tag handle for the source to draw the frame from the video. You can put this piece of code inside a timer to play the Video live in the Canvas.

In the latter case the MediaRecorder.ondataavailable handler doesn't receive valid data and the resulting video file is a 0-byte file.

En este c 2020-07-31 When you call drawImage(src, 0, 0) without specifying width/height it draws the entire src region, which in this case is much larger (the canvas is 320x420 versus the img at 185x70). So in the canvas case the browser is doing much more work, which explains the slower performance.

If you continue browsing the site, you agree to the use of cookies on this website. 主要思路： Canvas中可以使用ctx.drawImage(video, x, y,width,height)来对视频当前帧的图像进行绘制，其中video参数就是HTML5中的video标签。故我们可以通过Canvas的动态效果不断获取video当前画面，渲染到Canvas画布上。并且通过改变video标签的属性，来实现在Canvas中处理视频 function drawFrame(video) { context.drawImage(video, 0, 0); setTimeout(function { drawFrame(video); }, 10); } After we execute drawFrame, we create a loop executing drawFrame every 10ms — enough time to keep the video in sync in the canvas. Canvas provides a drawImage function which takes input the Video tag handle for the source to draw the frame from the video. You can put this piece of code inside a timer to play the Video live in the Canvas. Other two arguments are the co-ordinates in the Canvas where to draw the frame. ctx.drawImage(v,1,1); // Draw the paused frame of the The drawImage() method draws an image, canvas, or video onto the canvas.
