无论哪种方式，上面提到的错误都是 MEDIA_ERROR_UNKNOWN。如果这个视频是为这个应用程序制作的，我会确保它是为 Android 正确编码的。还要确保它明确定义了它的端点。

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

这是一种解决方法，但可能适用于您的情况：

@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
    }
}
