播放网络视频、本地视频；可以暂停、前后拖动、快进、快退、音量调节、下一个视频
环境：Unity5.6以上
Unity正式发布了5.6版本后，作为5.x版本的最后一版还是有不少给力的更新的。其中新加入了一个Video Player控件，用以取代之前的MovieTexture。
VideoPlayer API
VideoClip API
首先导入视频，因为默认不进行编码转换，现在的视频导入速度比以前快很多。
Video Player还提供了多种视频渲染的方式，包括Camera Far Plane，Camera Near Plane，Render Texture，Material Override，Api Only。
本地视频播放：
直接将视频拖到VideoClip上
这个时候就可以播放了。
网络视频播放：
将网络视频的链接写到URL上面
这个时候就可以播放了
也可以通过URL播放本地视频，Browse...可以选择本地视频的路径，并且自动生成URL
这个时候我们会发现，播放的时候没有声音。
我们只要添加一个Audio Source组件，将他赋给VideoPlayer里面的Audio Source就有声音了
整合视频播放：
脚本控制（需引用UnityEngine.Video）：
VideoPlayer的脚本控制与AudioSource相似，有常规的Play，Pause，Stop方法，也有用于进度控制的time，isPlaying，isLooping，frame，frameCount等属性。
用代码控制播放：
