记录：网页播放视频

好久不怎么完整的写代码了，突然要做个网页实现视频在线播放的，要的颇急，几个小时搞定。

自我提醒：仅仅支持IE播放，因为调用了media player播放，chrome不支持，还把所有的视频格式转化为wmv格式，可以实现边下载边播放。

其中播放路径的变量必须在后台做public声明，前段页面才可以调用，习惯了使用“~/”取路径，但是这个标记必须在服务器端控件中使用才有效。

例如：PlayUrl = http://webtest.域名.com/2013/video/百老汇.wmv,这样才可以实现放在服务器上播放，否则本地调试看不出情况，放到服务器上就傻眼了。

调用object代码如下：

<object id="MediaPlayer1" classid="clsid:22D6F312-B0F6-11D0-94AB-0080C74C7E95" width="800" height="600" VIEWASTEXT style="vertical-align:text-top;">
