推荐答案
正如@sjm所建议的那样，我玩了Popcorn.capture并尝试了下面的代码来实现这个技巧
As suggested by @sjm, I played around with Popcorn.capture and tried the following code which does the trick
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>Popcorn.capture.js Functional Examples</title>
<script src="http://cdn.popcornjs.org/code/dist/popcorn.min.js"></script>
<script src="../src/popcorn.capture.js"></script>
</head>
<body onload="myFunction()">
<div id="unmoved-fixture">
<video height="180" width="300" id="video-target" controls>
<source src="assets/popcorntest.mp4"></source>
<source src="assets/popcorntest.ogv"></source>
<source src="assets/popcorntest.webm"></source>
</video>
</div>
<pre>
</pre>
<script>
function myFunction() {
var $pop = Popcorn( "#video-target" ),
poster;
$pop.capture({
at: 10
});
}
</script>
</body>
</html>
以上代码从视频的第10秒开始捕获图像，并为视频创建海报图像。
The above code captures the image from 10th second of video and creates poster image for video.
