Umieszczanie VLCJ w JPanel

Question

Przeczytałem this SO thread i kiedy próbowałem użyć kodu z pewnymi zmianami, otrzymuję tylko czarne okno, czy ktoś może mi powiedzieć, co robię źle tutaj, mam tylko jedno klasa z główną funkcją:

import java.awt.Color; 
import javax.swing.JFrame; 
import javax.swing.JPanel; 

import com.sun.jna.NativeLibrary; 

import uk.co.caprica.vlcj.player.MediaPlayerFactory; 
import uk.co.caprica.vlcj.player.embedded.EmbeddedMediaPlayer; 
import uk.co.caprica.vlcj.player.embedded.videosurface.CanvasVideoSurface; 
import uk.co.caprica.vlcj.runtime.windows.WindowsCanvas; 

public class Canvas_Demo { 

    // Create a media player factory 
    private MediaPlayerFactory mediaPlayerFactory; 

    // Create a new media player instance for the run-time platform 
    private EmbeddedMediaPlayer mediaPlayer; 

    private JPanel panel; 
    private WindowsCanvas canvas; 
    private JFrame frame; 

    //Constructor 
    public Canvas_Demo(String url){ 

     //Creating a panel that while contains the canvas 
     panel = new JPanel(); 
     panel.setBackground(Color.BLACK); 

     //Creating the canvas and adding it to the panel : 
     canvas = new WindowsCanvas(); 
     panel.add(canvas); 
     panel.revalidate(); 
     panel.repaint(); 

     //Creation a media player : 
     mediaPlayerFactory = new MediaPlayerFactory(); 
     mediaPlayer = mediaPlayerFactory.newEmbeddedMediaPlayer(); 
     CanvasVideoSurface videoSurface = mediaPlayerFactory.newVideoSurface(canvas); 
     mediaPlayer.setVideoSurface(videoSurface); 

     //Construction of the jframe : 
     frame = new JFrame("Demo with Canvas AWT"); 
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     frame.setLocation(100, 100); 
     frame.setSize(700, 500); 

     //Adding the panel to the 
     frame.add(panel); 
     frame.setVisible(true); 

     //Playing the video 
     mediaPlayer.playMedia(url); 


    } 
    //Main function : 
    public static void main(String[] args) { 
     NativeLibrary.addSearchPath("libvlc", "C:/Program Files/VideoLAN/VLC"); 

     final String url = "C:/MyVideo.mp4"; 

     new Canvas_Demo(url); 

    } 

} 

Z góry dziękuję.

//Creating the canvas and adding it to the panel : 
canvas = new WindowsCanvas(); 
canvas.setSize(700, 500); 
panel.add(canvas); 

Answer 3

Zrobiłem coś takiego

EmbeddedMediaPlayerComponent mediaPlayerComponent = new EmbeddedMediaPlayerComponent(); 
     EmbeddedMediaPlayer embeddedMediaPlayer = mediaPlayerComponent.getMediaPlayer(); 

     Canvas videoSurface = new Canvas(); 
     videoSurface.setBackground(Color.black); 
     videoSurface.setSize(800, 600); 

     List<String> vlcArgs = new ArrayList<String>(); 

     vlcArgs.add("--no-plugins-cache"); 
     vlcArgs.add("--no-video-title-show"); 
     vlcArgs.add("--no-snapshot-preview"); 

     MediaPlayerFactory mediaPlayerFactory = new MediaPlayerFactory(vlcArgs.toArray(new String[vlcArgs.size()])); 
     mediaPlayerFactory.setUserAgent("vlcj test player"); 
     embeddedMediaPlayer.setVideoSurface(mediaPlayerFactory.newVideoSurface(videoSurface)); 
     embeddedMediaPlayer.setPlaySubItems(true); 

     final PlayerControlsPanel controlsPanel = new PlayerControlsPanel(embeddedMediaPlayer); 
     PlayerVideoAdjustPanel videoAdjustPanel = new PlayerVideoAdjustPanel(embeddedMediaPlayer); 

//   mediaPlayerComponent.getMediaPlayer().playMedia(Constant.PATH_ROOT + Constant.PATH_MEDIA + "tmp.mp4"); 
     JFrame mainFrame = new JFrame(); 
     mainFrame.setLayout(new BorderLayout()); 
     mainFrame.setBackground(Color.black); 
     mainFrame.add(videoSurface, BorderLayout.CENTER); 
     mainFrame.add(controlsPanel, BorderLayout.SOUTH); 
     mainFrame.add(videoAdjustPanel, BorderLayout.EAST); 

     //create a button which will hide the panel when clicked. 
     mainFrame.pack(); 
     mainFrame.setVisible(true); 

     embeddedMediaPlayer.playMedia("tmp.mp4");
