创建视频播放器​

• 在Hierarchy面板中右键创建：Video > AVPro Video - MediaPlayer
• 创建后会生成一个MediaPlayer对象，用于控制视频播放

添加视频资源

• 将视频文件放入项目的StreamingAssets文件夹下
• 在MediaPlayer组件的设置中选择要播放的视频文件

在UI上显示视频​

• 创建Canvas对象
• 在Canvas下添加DisplayUGUI组件用于将视频渲染到UI
• 将MediaPlayer拖拽到DisplayUGUI组件中

unity avpro切换视频播放

核心思路，需要切换视频时。将当前视频A截一帧图片pic显示。播放器加载第二个视频，等第二个视频B事件MediaPlayerEvent.EventType.FirstFrameReady，延迟一帧将图片pic隐藏即可。

实现简单影游根据选项跳转不同视频播放
