無論哪種方式，上面引用的錯誤是MEDIA_ERROR_UNKNOWN。如果這個視頻是爲這個應用程序，我會確保它是適當的Android編碼。還要確保清楚地定義了它的端點。

http://developer.android.com/reference/android/media/MediaPlayer.html#MEDIA_ERROR_UNKNOWN

這是一個解決辦法，但可能會在您的情況possbly工作：

@Override 
public boolean onError(MediaPlayer mp, int what, int extra) { 
    if(what == MediaPlayer.MEDIA_ERROR_UNKNOWN) 
     //ERROR UNKNOWN - COULD BE IMPROPERLY FORMATTED VIDEO { 
     //MOVE ON TO NEXT VIDEO 
     //DO LOGGING 
    } 
}
