如何写兼容的视频标签？

由于旧的浏览器和Internet Explorer不支持39000f942b2545a5315c57fa3276f220元素，考虑到兼容性，我们必须为这些浏览器找到一个支持Flash文件的解决方案。不幸的是，和HTML 5音频一样，涉及到视频的文件格式，Firefox 和 Safari/Chrome 的支持方式并不相同。因此，如果你想在这个时候使用HTML 5视频，则需要创建三个视频版本。OGG，MP4，FLV/SWF

复制代码

代码如下:

<video width="320" height="240" controls> 
<!-- 兼容 Firefox --> 
<source src="http://www.jb51.net/ movie.ogg" type="video/ogg" /> 
<!-- 兼容 Safari/Chrome--> 
<source src="http://www.jb51.net/ movie.mp4" type="video/mp4" /> 
<!-- 如果浏览器不支持video标签，则使用flash --> 
<embed src="http://www.jb51.net/ movie.swf" type="application/x-shockwave-flash" 
width="320" height="240" allowscriptaccess="always" allowfullscreen="true"></embed>
