Play a video with vlcj on a Mac

Question

Hi I'm trying to get a video running with vlcj on a mac. I tried several things but everywhere there is something wrong. The Programm is starting up, but there is no video playing. Does anyone know how to handle vlcj on a mac? My intentions are to play a rtsp stream on a mac with java. I tried it first with opencv and now vlcj but didn't succed.

Are there any good examples how to do that on a mac or does anyone know why it is not working?

Thanks

Code:

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JFrame;
import javax.swing.SwingUtilities;
import javax.swing.Timer;

import uk.co.caprica.vlcj.binding.LibVlc;
import uk.co.caprica.vlcj.component.EmbeddedMediaPlayerComponent;
import uk.co.caprica.vlcj.runtime.RuntimeUtil;

import com.sun.jna.Native;
import com.sun.jna.NativeLibrary;

public class VideoExample {

    private final EmbeddedMediaPlayerComponent mediaPlayerComponent;

    public static void main(final String[] args) {


        uk.co.caprica.vlcj.binding.LibC.INSTANCE.setenv("VLC_PLUGIN_PATH", "/Applications/VLC.app/Contents/MacOS/plugins", 1);

        NativeLibrary.addSearchPath(RuntimeUtil.getLibVlcLibraryName(), "/Applications/VLC.app/Contents/MacOS/lib");
        Native.loadLibrary(RuntimeUtil.getLibVlcLibraryName(), LibVlc.class);
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                new VideoExample(args);
            }
        });
    }

    private VideoExample(String[] args) {
        JFrame frame = new JFrame("vlcj Tutorial");

        mediaPlayerComponent = new EmbeddedMediaPlayerComponent();

        frame.setContentPane(mediaPlayerComponent);

        frame.setLocation(100, 100);
        frame.setSize(500, 500);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);

        mediaPlayerComponent.getMediaPlayer().playMedia("/test.m4v");

    } 
}

Here is everything explained step by step http://capricasoftware.co.uk/#/projects/vlcj/tutorial/direct-rendering

the rtsp stream works perfectly fine if you are ok with 3 seconds delay
