使用HTML 5 播放视频。动态截图

< ![CDATA[

暂不支持chrom 。支持safari  .其他未测试

 

 先引用 jquery 地址。选用新浪的

<script type="text/javascript" src="http://lib.sinaapp.com/js/jquery/1.6/jquery.js"></script>

　

加一个video标签 

<video id="video" controls="controls">
<source src="1.mp4" />
</video>

 

然后js

<script type="text/javascript">

   $().ready(function(){
 
    var video, output;
    var scale = 0.25;
 
    var initialize = function() {
        output = $("#output");
        video = $("#video").get(0);
        $("#capture").click(captureImage);                
    };
 
    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();
        output.prepend(img);
    };
 
    $(initialize);            
 
});
    </script>
