javafx声音/视频播放

Question

我一直在尝试使用 JavaFX 播放一些 mp3、视频，但没有结果。我还搜索了这个论坛上的每个主题，寻找解决方案，但没有成功......如果有人可以帮助我，我将不胜感激

这是我的代码:

  @Override
public void start(Stage primaryStage) throws MalformedURLException {
    primaryStage.setTitle("Embedded Media Player");
    Group root = new Group();
    Scene scene = new Scene(root, 540, 241);
    File f = new File("src/sample/test2.mp3");

    Media media = new Media(f.toURI().toString());

    MediaPlayer mediaPlayer = new MediaPlayer(media);
    mediaPlayer.setAutoPlay(true);

    MediaView mediaView = new MediaView(mediaPlayer);

    System.out.println("mediaPlayer.getMedia() = " + mediaPlayer.getMedia().getSource());
    System.out.println("mp.getStatus() = " + mediaPlayer.getStatus());
    System.out.println("mediaPlayer.getTotalDuration() = " + mediaPlayer.getTotalDuration());
    System.out.println("mediaPlayer.getMedia().getSource() = " + mediaPlayer.getMedia().getSource());

    ((Group)scene.getRoot()).getChildren().add(mediaView);
    primaryStage.setScene(scene);
    primaryStage.show();
    mediaPlayer.play();

和输出:

mediaPlayer.getMedia() = file:/C:/Users/Piotr/Desktop/okon/src/sample/test2.mp3
mp.getStatus() = UNKNOWN
mediaPlayer.getTotalDuration() = UNKNOWN
mediaPlayer.getMedia().getSource() = file:/C:/Users/Piotr/Desktop/okon/src/sample/test2.mp3

编辑:迁移到 Ubuntu 解决了我的问题

添加监听器:

mediaPlayer.statusProperty().addListener(new ChangeListener() { @覆盖 公共(public)无效改变(ObservableValue observable，对象oldValue，对象newValue){ System.out.println("mp.getStatus() = "+ mediaPlayer.getStatus()); System.out.println("mediaPlayer.getTotalDuration() = "+ mediaPlayer.getTotalDuration()); } });
