java - 使用 VLCJ 播放文件序列

Question

第一次使用VLCJ。我可以播放一个文件，但我需要连续播放多个文件。我意识到有一个用于 mediaEnded 的 EventListener，但我不知道如何使用它...我对 Java 有点陌生，这是我第一次使用 GUI。我想我只需要帮助设置监听器，我可以自己将其连接到我的程序。任何帮助，将不胜感激。如果有帮助，我将使用 EmbeddedMediaPlayerComponent 来播放文件。谢谢您

在 VLCJ 示例中找到解决方案

公共(public)类 TestMediaListEmbeddedPlayer 扩展了 VlcjTest {

public static void main(String[] args) throws Exception {
    MediaPlayerFactory mediaPlayerFactory = new MediaPlayerFactory();

    Canvas canvas = new Canvas();
    canvas.setBackground(Color.black);
    CanvasVideoSurface videoSurface = mediaPlayerFactory.newVideoSurface(canvas);

    EmbeddedMediaPlayer mediaPlayer = mediaPlayerFactory.newEmbeddedMediaPlayer();
    mediaPlayer.setVideoSurface(videoSurface);

    MediaListPlayer mediaListPlayer = mediaPlayerFactory.newMediaListPlayer();

    mediaListPlayer.addMediaListPlayerEventListener(new MediaListPlayerEventAdapter() {
        @Override
        public void nextItem(MediaListPlayer mediaListPlayer, libvlc_media_t item, String itemMrl) {
            System.out.println("nextItem()");
        }
    });

    mediaListPlayer.setMediaPlayer(mediaPlayer); // <--- Important, associate the media player with the media list player

    JPanel cp = new JPanel();
    cp.setBackground(Color.black);
    cp.setLayout(new BorderLayout());
    cp.add(canvas, BorderLayout.CENTER);

    JFrame f = new JFrame("vlcj embedded media list player test");
    f.setIconImage(new ImageIcon(TestMediaListEmbeddedPlayer.class.getResource("/icons/vlcj-logo.png")).getImage());
    f.setContentPane(cp);
    f.setSize(800, 600);
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.setVisible(true);

    MediaList mediaList = mediaPlayerFactory.newMediaList();
    String[] options = {};
    mediaList.addMedia("C:\\Documents and Settings\\DEVELOPER\\Desktop\\videoplayback1.mp4", options);
    mediaList.addMedia("C:\\Documents and Settings\\DEVELOPER\\Desktop\\videoplayback2.mp4", options);

    mediaListPlayer.setMediaList(mediaList);
    mediaListPlayer.setMode(MediaListPlayerMode.LOOP);

    mediaListPlayer.play();

    // This looping is just for purposes of demonstration, ordinarily you would
    // not do this of course
    for(;;) {
        Thread.sleep(500);
        mediaPlayer.setChapter(3);

        Thread.sleep(5000);
        mediaListPlayer.playNext();
    }

    //    mediaList.release();
    //    mediaListPlayer.release();
    //    mediaPlayer.release();
    //    mediaPlayerFactory.release();
}

}
