Java swing: perform action when video is finished

Question

I have embedded a youtube video as shown here. Now I want something to happen, when the video finishes.

I guess the hard way would be to download the video as an object etc.

Is there an easier way?

Any help would be appreciated.

Answer 1

The JWebBrowser component from The DJ project as used in the very nice example by Jk1 supports a listener that you can add to it to receive browser events. You could use these events to search for specific events that indicate the video is finished. This depends on how YouTube works, which could be platform/browser dependent and will change over time. So no hard science here, but perhaps this approach is good enough for your situation.

Here is the modified code of the above mentioned example, which adds a listener for the browser events (implementing only two of the ten available WebBrowserListener methods) and some logging. I used DJNativeSwing-SWT-1-0-2 and swt-4.5-win32-win32-x86_64:

import java.awt.*;
import java.text.*;
import java.util.*;
import javax.swing.*;
import chrriis.dj.nativeswing.swtimpl.*;
import chrriis.dj.nativeswing.swtimpl.components.*;

public class YouTubeViewerV2 {
    private static final DateFormat DATE_FORMAT = new SimpleDateFormat("mm:ss.SSS");

    private JWebBrowser webBrowser;

    public static void main(String[] arguments) {
        new YouTubeViewerV2().createAndShowGui();
    }

    private void createAndShowGui() {
        NativeInterface.open();

        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                JFrame frame = new JFrame("YouTube Viewer");
                frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
                frame.getContentPane().add(getBrowserPanel(), BorderLayout.CENTER);
                frame.setSize(800, 600);
                frame.setLocationByPlatform(true);
                frame.setVisible(true);
            }
        });

        NativeInterface.runEventPump();

        // Don't forget to properly close native components.
        Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() {
            @Override
            public void run() {
                NativeInterface.close();
            }
        }));
    }

    private JPanel getBrowserPanel() {
        JPanel webBrowserPanel = new JPanel(new BorderLayout());

        webBrowser = new JWebBrowser();
        webBrowser.setBarsVisible(false);
        //webBrowser.navigate("https://www.youtube.com/v/b-Cr0EWwaTk?fs=1");
        webBrowser.navigate("https://youtu.be/RnqAXuLZlaE?t=3m7s");
        webBrowser.addWebBrowserListener(getBrowserListener());

        webBrowserPanel.add(webBrowser, BorderLayout.CENTER);

        return webBrowserPanel;
    }

    private WebBrowserListener getBrowserListener() {
        return new WebBrowserAdapter() {
            @Override
            public void loadingProgressChanged(WebBrowserEvent e) {
                log("Loading progress changed: " + webBrowser.getLoadingProgress());
                log("");
            }

            @Override
            public void statusChanged(WebBrowserEvent e) {
                log("Status changed - text: " + webBrowser.getStatusText());
                log("Status changed - location: " + webBrowser.getResourceLocation());
                log("");
            }
        };
    }

    private void log(String line) {
        System.out.println("[" + DATE_FORMAT.format(new Date()) + "] " + line);
    }
}

And here the output for a short test:

On my machine, the statusChanged event where the status text of the webBrowser field is "Downloading picture res://ieframe.dll/background_gradient.jpg..." seems to indicate that the video is finished.
