創建視頻播放器?

• 在Hierarchy面板中右鍵創建：Video > AVPro Video - MediaPlayer
• 創建后會生成一個MediaPlayer對象，用于控制視頻播放

添加視頻資源

• 將視頻文件放入項目的StreamingAssets文件夾下
• 在MediaPlayer組件的設置中選擇要播放的視頻文件

在UI上顯示視頻?

• 創建Canvas對象
• 在Canvas下添加DisplayUGUI組件用于將視頻渲染到UI
• 將MediaPlayer拖拽到DisplayUGUI組件中

unity avpro切換視頻播放

核心思路，需要切換視頻時。將當前視頻A截一幀圖片pic顯示。播放器加載第二個視頻，等第二個視頻B事件MediaPlayerEvent.EventType.FirstFrameReady，延遲一幀將圖片pic隱藏即可。

實現簡單影游根據選項跳轉不同視頻播放
