Untiy的Webgl端网页端视频播放，又不想直接mp4格式等格式的。

针对Untiy的Webgl端网页端视频播放，又不想直接mp4格式等格式的一些小技巧方式。

1.安装AVPro Video插件。

2.场景ui布局类似如下图：

3.UI中新建image，改名VideoDisplay，把image组件删除，添加Displayugui组件，关联mediaplayer。

4.UI中新建gameobject，添加mediapalyer组件，并关联你要播放的某个视频。

5.新建gameobject，添加HTML5VideoPlayer组件，并设置如下，videofilename的名称就是你的视频名称，视频位置webgl网页端主要是放在StreamingAssets中，视频的后缀名可以改为我这个名称。然后你同步设置也要同名称。

6.这个组件可以播放多个视频，你只要有多个panel拷贝下就行了。

相关的HTML5VideoPlayer代码如下：
