Java und DivX bzw. XviD

Das das Java Media Framework alles andere als aktuell ist, läßt sich sehr einfach "Fobs" dazu benutzen, trotzdem "aktuelle" Codecs wie DivX und XviD decodieren zu können.

VideoFrame.java

package media;

import java.awt.BorderLayout;
import java.net.URL;

import javax.swing.WindowConstants;

public class VideoFrame extends javax.swing.JFrame {

    private static final long serialVersionUID = 6688121132497051736L;

    public static void main(String[] args) {
        VideoFrame inst = new VideoFrame();
        inst.setVisible(true);
        inst.setTitle("Java Media Player – Dennis Wilmsmann 2007");
    }

    private VideoPanel myMediaPanel;

    public VideoFrame() {
        super();
        initGUI();
    }

    private void initGUI() {
        try {
            setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
            {
                URL url = new URL("http://insert a valid url here");
                myMediaPanel = new VideoPanel(url);
                getContentPane().add(myMediaPanel, BorderLayout.CENTER);
            }
            pack();
            setSize(588, 448);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

Dazu müssen nun noch die fobs4jmf.dll und jmf.properties im selben Verzeichnis liegen und die fobs4jmf.jar in den Java Build Path integriert werden.
