Malerei über JMF Komponente

Question

Ich bin der Erfassung der Strom von einer Webcam und möchte etwas auf dem Videobild zeichnen. Ich versuche, dass im Beispiel unten, das Problem ist, dass die andere Komponente immer im Hintergrund ist egal, wie ich die Komponenten arrangieren. Gibt es eine Möglichkeit, dies zu lösen?

public class SwingCapture extends JPanel {

private static final long serialVersionUID = -1284686239737730338L;
private static Player player = null;
public static final int WIDTH = 640;
public static final int HEIGHT = 480;
private MediaLocator ml = null;

public SwingCapture() 
{
    setLayout(null);
    setSize(WIDTH, HEIGHT);

    ml = new MediaLocator("vfw:Microsoft WDM Image Capture (Win32):0"); 
    try  {
        player = Manager.createRealizedPlayer(ml);
        player.start();

        Component comp = null;
        if ((comp = player.getVisualComponent()) != null) {
            add(comp);   
            comp.setBounds(0, 0, 640, 480);
        }
        add(Canvas.getInstance());
        Canvas.getInstance().setBounds(0, 0, 640, 480);
    } 
    catch (Exception e) 
    {
      e.printStackTrace();
    }
}

public static void playerclose() {
   player.close();
   player.deallocate();
}
}

Ich habe das Problem gelöst. Ich benutzte einen Manager.setHint (Manager.LIGHTWEIGHT_RENDERER, true);  und ein JLayerPane.

public class SwingCapture extends JPanel {
private static final long serialVersionUID = -1284686239737730338L;
public static Player player = null;
public static final int WIDTH = 640;
public static final int HEIGHT = 480;
public MediaLocator ml = null;

public SwingCapture() {
    setLayout(null);
    setSize(WIDTH, HEIGHT);
    JLayeredPane jLP = new JLayeredPane(); 
    jLP.setBounds(0,0,800,600);
    ml = new MediaLocator("vfw:Microsoft WDM Image Capture (Win32):0"); 
    try  {
        Manager.setHint(Manager.LIGHTWEIGHT_RENDERER, true);
        player = Manager.createRealizedPlayer(ml);
        player.start();
        jLP.add(Canvas.getInstance());
        Canvas.getInstance().setBounds(0, 0, 200, 200);
        Component comp = null;
        if ((comp = player.getVisualComponent()) != null) {
            jLP.add(comp, -1);   
            comp.setBounds(0, 0, 640, 480);
        }

        add(jLP);
    } catch (Exception e) {
      e.printStackTrace();
    }
}

 public static void playerclose() 
 {
    player.close();
    player.deallocate();
 }
}
