libVLC can’t play a movie via RTSP streaming on MS Surface Pro 7+ with the display driver “Intel(R) Iris(R) Xe Graphics”

[SHIMADA_Kiichiro]

Hello,

I’m developing RTSP streaming movie player application on .NET Framework C# WPF and libVLC is referred by the application.

And now, I’m facing the trouble about playing RTSP streaming movie.
No images display on the monitor.

As the result of some trials, it seems the problem between libVLC and display driver (Intel(R) Iris(R) Xe Graphics).
Please see below results.

Could anyone please help me to solve this problem?

how do you change your display driver? Try to disable hardware decoding

Code: Select all

new MediaPlayer { EnableHardwareDecoding = false }

[SHIMADA_Kiichiro]

how do you change your display driver?

I changed it on device manager of Windows 10.
'Windows key' + 'X' -> Device manager -> Display adapter -> Select adapter and right click -> Update driver

Try to disable hardware decoding

I'm not sure how to disable hardware decoding by using "Vlc.DotNet.Wpf.VlcControl".

Here is code snippet.
Could you please tell me how to disable based on it?

Code: Select all

private void PlayButtonClick(object sender, RoutedEventArgs e) { Console.WriteLine("PlayButtonClick"); // set RTSP URL _sourceUrl = URLTextBox.Text; _vlcCtrl = new Vlc.DotNet.Wpf.VlcControl(); if (_vlcCtrl != null && _vlcCtrl.SourceProvider.MediaPlayer == null) { // VlcControl instance set WPF control this.ControlContainer.Content = _vlcCtrl; _vlcCtrl.SourceProvider.CreatePlayer(_vlcLibDirectory); _vlcCtrl.SourceProvider.MediaPlayer.EncounteredError -= MediaPlayerEncounteredError; _vlcCtrl.SourceProvider.MediaPlayer.EncounteredError += MediaPlayerEncounteredError; _vlcCtrl.SourceProvider.MediaPlayer.Playing -= MediaPlayerPlaying; _vlcCtrl.SourceProvider.MediaPlayer.Playing += MediaPlayerPlaying; // For debug log _vlcCtrl.SourceProvider.MediaPlayer.Log += (_, args) => { string message = $"libVlc : {args.Level} {args.Message} @ {args.Module} \r\n"; this.Dispatcher.Invoke((Action)(() => { debug_console.Text += message; })); }; } Task.Run(() => { _vlcCtrl.SourceProvider.MediaPlayer.Play(new Uri(_sourceUrl)); }); }

[mfkl]

Give

Code: Select all

":avcodec-hw=none"

as an argument to Play() or SetMedia()

[SHIMADA_Kiichiro]

Thank you for your answer.
I tried as below.

Code: Select all

Task.Run(() => { string[] options = new string[] { ":avcodec-hw=none" }; _vlcCtrl.SourceProvider.MediaPlayer.Play(new Uri(_sourceUrl), options); });

As the result, the problem was not resolved.
I attach the log again.

Hello, a little update here.

I found libvlc update '3.0.14' and tried it.
But the problem didn't resolve.

Can anyone help me?
