c# AVPro Video - Ultra Edition官方插件使用介紹
AvproVideo，官網(wǎng)中有免費的，免費的帶了水印。不介意水印去下載，挺好使的。收費的在Unity商店中能找到：（這里我從淘寶上花“重金”買了一個玩玩）以前都是用的AvPro免費版的，1點幾那種版本的，也挺好使，相對這個來說，這個就是某東版本的，那個是拼夕夕版本的。
常用API
獲取MediaPlayer組件，使用代碼如下：
MediaPlayer meida;
//播放
media.Control.Play();
//暫停
media.Control.Pause();
//停止
media.Control.Stop();
//重播
media.Control.Rewind();
//設置播放鏈接AbsolutePathOrURL是Url的形式，可以選擇文件夾的形式，設置對應文件夾屬性即可
media.OpenMedia(MediaPathType.AbsolutePathOrURL,"視頻鏈接",true);
//StreamingAssets文件目錄下的視頻地址
media.OpenMedia(MediaPathType.RelativeToStreamingAssetsFolder,"視頻名稱",true);
//事件監(jiān)聽
media.Events.AddListener(OnVideoEvent);
private void OnVideoEvent(MediaPlayer arg0, MediaPlayerEvent.EventType arg1, ErrorCode arg2)
{
switch (arg1)
{
case MediaPlayerEvent.EventType.MetaDataReady:
break;
case MediaPlayerEvent.EventType.ReadyToPlay:
break;
case MediaPlayerEvent.EventType.Started:
break;
case MediaPlayerEvent.EventType.FirstFrameReady:
break;
case MediaPlayerEvent.EventType.FinishedPlaying:
print("無循環(huán)狀態(tài)下播放完成");
break;
case MediaPlayerEvent.EventType.Closing:
print(".Closing...");
break;
case MediaPlayerEvent.EventType.Error:
print(".Error...");
break;
case MediaPlayerEvent.EventType.SubtitleChange:
break;
case MediaPlayerEvent.EventType.Stalled:
break;
case MediaPlayerEvent.EventType.Unstalled:
break;
case MediaPlayerEvent.EventType.ResolutionChanged:
break;
case MediaPlayerEvent.EventType.StartedSeeking:
break;
case MediaPlayerEvent.EventType.FinishedSeeking:
print("循環(huán)設置狀態(tài)下播放結束...");
break;
case MediaPlayerEvent.EventType.StartedBuffering:
break;
case MediaPlayerEvent.EventType.FinishedBuffering:
break;
case MediaPlayerEvent.EventType.PropertiesChanged:
break;
case MediaPlayerEvent.EventType.PlaylistItemChanged:
break;
case MediaPlayerEvent.EventType.PlaylistFinished:
break;
case MediaPlayerEvent.EventType.TextTracksChanged:
break;
//case MediaPlayerEvent.EventType.TextCueChanged://=> SubtitleChange
// break;
default:
break;

結語
相對Unity自帶的VideoPlayer，我更喜歡用這個，功能更齊全，主要是好使，某些平臺更好使。
注意這個收費插件在安卓下使用需要在PlayerSettings => OtherSettings =>Rendering =>AutoGraphicsAPI需要取消掉，然后GraphicsAPIS設置OpenGL2或者3.
