视频播放功能模块

终于可以静下心来写一下日志了，下面是做的一块关于视频播放的功能，主要是要用到插件AVProQuickTime,已经用过多次，还是非常不错的，不过这个项目是基于4.3版本的，比较老，属于在维护。
主摄像机上挂载AVProQuickTimeManager即可，然后新建一个对象命名为MovieObject,然后挂载AVProQuickTimeGUIDisplay，和AVProQuickTimeMovie，但是在后者中，我们对视频资源的地址进行了更改，方便后面更换，更改后代码如下：

最后是关于视频快进暂停，进度条的相关控制，只需要下面的一个脚本就行，然后给相应的变量赋值，直接在inspector中拖到对应位置比较方便。
