Unable to load libraries libvlc

Question

I have this code:

    public class MediaPanel {

        public static void main(final String[] args) {
            SwingUtilities.invokeLater(new Runnable() {
                @Override
                public void run() {
                     chargerLibrairie();
                     new MediaPanel(args);
                }
            });
        }
       static void chargerLibrairie(){   String ruta="C:/VideoLAN/VLC";
             NativeLibrary.addSearchPath(RuntimeUtil.getLibVlcLibraryName(), ruta);
            Native.loadLibrary(RuntimeUtil.getLibVlcLibraryName(), LibVlc.class);

            LibXUtil.initialise();

        }

        private MediaPanel(String[] args) {
            JFrame frame = new JFrame("Tutoriel vlcj");
            frame.setLocation(100, 100);
            frame.setSize(1050, 600);
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setVisible(true);

            //Créer une instance de Canvas
            Canvas c = new Canvas();
            //L'arrière plan de la vidéo est noir par défaut
            c.setBackground(Color.black);
            JPanel p = new JPanel();
            p.setLayout(new BorderLayout());
            //La vidéo prend toute la surface
            p.add(c, BorderLayout.CENTER);
            frame.add(p, BorderLayout.CENTER);

            //Créer une instance factory
            MediaPlayerFactory mediaPlayerFactory = new MediaPlayerFactory();
            //Créer une instance lecteur média
            EmbeddedMediaPlayer mediaPlayer = mediaPlayerFactory.newEmbeddedMediaPlayer();
            mediaPlayer.setVideoSurface(mediaPlayerFactory.newVideoSurface(c));
            //Plein écran
            mediaPlayer.toggleFullScreen();
            //Cacher le curseur de la souris à l'intérieur de JFrame
            mediaPlayer.setEnableMouseInputHandling(false);
            //Désactiver le clavier à l'intérieur de JFrame
            mediaPlayer.setEnableKeyInputHandling(true);

            //Préparer le fichier
            mediaPlayer.prepareMedia("J.mp4");
            //lire le fichier 
            mediaPlayer.play();
        }
    }

And I have this error:

run:
Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: Unable to load library 'libvlc': Native library (win32-x86-64/libvlc.dll) not found in resource path ([file:/C:/Users/Jes%c3%bas/Desktop/videoProyecto/jna-4.0.0.jar, file:/C:/Users/Jes%c3%bas/Desktop/videoProyecto/jna-platform-4.0.0.jar, file:/C:/Users/Jes%c3%bas/Desktop/videoProyecto/vlcj-2.4.0.jar, file:/C:/Users/Jes%c3%bas/Documents/NetBeansProjects/edicionVideo/build/classes/])

It seems that the directory is correct, but I think it doesn't load the libraries from vlc. I have ensured that the libraries are the same architecture as my pc, 64 bits, and I don't really know what the problem is.

Answer 1

cd src/main/resources/
cp -r /Applications/VLC.app/Contents/MacOS/lib darwin
rm darwin/*.*.*
cd darwin
install_name_tool -add_rpath @loader_path libvlc.dylib
mkdir vlc
cp -r /Applications/VLC.app/Contents/MacOS/plugins vlc/plugins

This is the macOS version. Worked for me. Maybe help you.

Answer 2

Sometimes the problem is due to incompatibility of the architecture of VLC and JRE.

You can check JRE architecture using the code below:

public class JavaApplication12 {
    public static void main(String[] args) {
        System.out.println(System.getProperty("sun.arch.data.model"));
    }
}

If VLC is 32bit then the JRE must be 32 bit too, and if VLC is 64 then JRE must be 64 too.
