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
Code: Select all
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);
}
private void Play()
{
_mediaPlayer.Play();
