Java swing: выполнить действие после завершения видео

Я встроил видео на YouTube, как показано здесь. Теперь я хочу, чтобы что-то случилось, когда видео закончится.

Я думаю, что сложный способ - загрузить видео как объект и т. Д.

Есть ли более простой способ?

Любая помощь будет оценена.

JWebBrowser Компонент из проекта DJ, используемый в очень хорошем примере Jk1, поддерживает слушателя, который вы можете добавить к нему для получения событий браузера. Вы можете использовать эти события для поиска определенных событий, которые указывают, что видео закончено. Это зависит от того, как работает YouTube, который может зависеть от платформы / браузера и будет меняться со временем. Так что никакой твердой науки здесь нет, но, возможно, этот подход достаточно хорош для вашей ситуации.

Вот модифицированный код вышеупомянутого примера, который добавляет слушатель для событий браузера (реализуя только два из десяти доступных WebBrowserListener методы) и некоторые записи. Я использовал DJNativeSwing-SWT-1-0-2 и 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);
    }
}

И вот вывод для краткого теста:

На моей машине statusChanged событие, где текст статуса webBrowser поле "Загрузка изображения res://ieframe.dll/background_gradient.jpg...", кажется, указывает, что видео закончено.
