Question

我在ubuntu上尝试过JavaFx MediaPlayer，但是在运行时它会告诉我

"MediaException: UNKNOWN : com.sun.media.jfxmedia.MediaException: Could not create player!"

任何人都知道如何解决它？我已经尝试了大部分我可以google-ed，安装了ffmpeg，java8和jfxrt.jar。
对此有更简单的方法或模块测试方法吗？提前谢谢！

java -version = Java（TM）SE运行时环境（版本1.8.0_77-b03）

    System.out.println("Hello World");
    File f = new File("a.mp3");
    System.out.println("F=" + f.exists());

    try {
        final Media media = new Media(f.toURI().toString());
        final MediaPlayer mediaPlayer = new MediaPlayer(media);
        mediaPlayer.setAutoPlay(true);
        mediaPlayer.play();
    } catch (Exception e1) {
        e1.printStackTrace();
    }
