java - 无法使用 JavaFX 播放 mp3 文件

Question

我试图通过单击按钮来播放 mp3 文件，但com.sun.media.jfxmedia.MediaException:无法创建播放器!被抛出。

当我尝试使用文件名中带有空格的歌曲时，它抛出了非法字符异常

代码如下:

@FXML
void playSong(ActionEvent event) {
    File file = new File("/home/havoc/Music/bb.mp3");
    String path = file.getAbsolutePath();
    Media media = new Media("file://"+path);
    System.out.println(media.getSource());
    MediaPlayer player = new MediaPlayer(media);
    player.play();
}

错误如下:

在 Windows 上尝试了代码，效果很好，结果在 Linux 上你需要 FFmpeg-compact54 才能使用 JavaFX 播放媒体。
