javafx声音/视频播放

我一直在尝试使用JavaFX播放一些mp3和视频，但没有结果。我也搜索了这个论坛上的每一个主题，寻找解决方案，但没有成功。。。 如果有人能帮助我，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();

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

和输出：

  @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();

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： 转到Ubuntu解决了我的问题

添加一个侦听器：

mediaPlayer.statusProperty（）.addListener（新的ChangeListener（））{ @凌驾 公共无效已更改（可观察值可观察、对象旧值、对象新值）{ System.out.println（“mp.getStatus（）=”+mediaPlayer.getStatus（））； System.out.println（“mediaPlayer.getTotalDuration（）=”+mediaPlayer.getTotalDuration（））； }

---

});

你的位置看起来还不错。您可以尝试使用

Media Media=new Media（getClass（）.getResource（“/sample/test2.mp3”）.toExternalForm（））并更新您的发现？
