m_libVLC = new LibVLC();
}
private void MainWindow_Loaded(object sender, RoutedEventArgs e)

VideoView.MediaPlayer = new LibVLCSharp.Shared.MediaPlayer(m_libVLC);
VideoView.MediaPlayer.Play(new Media(m_libVLC, new Uri(uri)));
}

故障原因
打断点调试发现，Loaded时间执行两次，第一次执行在VideoView播放正常，第二次执行弹出VLC (Direct3D11 output)窗
解决方法: 控制只初始化和播放一次
