    {
        public TestPage()
        {
            InitializeComponent();
            Core.Initialize();
            LibVLC libVlc = new LibVLC();
            MediaPlayer mediaPlayer = new MediaPlayer(libVlc)
            {
                EnableHardwareDecoding = true,

            };
            mediaPlayer.Media = new Media(libVlc, new Uri("http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/ElephantsDream.mp4"));
            MediaPlayerElement.MediaPlayer = mediaPlayer;
            MediaPlayerElement.LibVLC = libVlc;
            MediaPlayerElement.IsVisible = true;
            mediaPlayer.Play();
        }
    }
}

Using r8 needs a bit more config.

Create a new file in your Xamarin.Android app root named "r8.cfg". In this file properties, set the Build Action to "ProguardConfiguration". In this file, add the following lines:

-keep class org.videolan.** { *; }
-dontwarn org.videolan.**
