Thanks for your help. With regards,
I have implemented LibVLCSharp inside WPF application to show Raspberry Pi Camera streaming and I'm having problems only in one Platform.
I have enabled VLC internal logging to debug and I have seen something strange comparing to a PC whitch works properly. I can see the messages zd candidates and I supose that maybe the problem.Intel Pentium CPU N4200 1.10 Ghz
4GB RAM
64 bit operating system
Windows 10 Enterprise 2016 LTSB (10.0, build 14393)
DirectX version: DirectX 12
VLC application is workwing correctly in same PC. What kind of problem could be happening here.
Here is the code whitch i'm using to initilize libvlc

private static string[] LIBVLC_OPTIONS_NORMAL = { "--no-snapshot-preview", "--no-osd" };
private static string[] LIBVLC_OPTIONS_ROTATED = { "--no-snapshot-preview", "--no-osd", "--video-filter=transform", "--transform-type=180" };
private void InitializeLibVlc()
{
CreateMedia();
_mediaPlayer = new MediaPlayer(_media);
_mediaPlayer.AspectRatio = "16:9";
_mediaPlayer.SetVideoTitleDisplay(Position.Disable, 0);
AssociatedObject.MediaPlayer = _mediaPlayer;
}
private void CreateMedia()

_libVLC?.Dispose();
_media?.Dispose();
_libVLC = new LibVLC(enableDebugLogs: true, rotated ? LIBVLC_OPTIONS_ROTATED : LIBVLC_OPTIONS_NORMAL);
_libVLC.Log += _libVLC_Log;
_media = new Media(_libVLC, new Uri(_streamURL));
}
private void _libVLC_Log(object sender, LogEventArgs e)
{
_logService.Write(CameraModule.LIBVLC_LOG, e.FormattedLog, LogCategory.Debug);
}
