Does the Jlayer Basicplayer API not open mp3 with Inputstream?

Hello everyone would like to know what’s wrong with my code. The Basicplayer library opens mp3 if you use File but do not open mp3 using Inputstream! That’s right?

 public class BasicPlayerTest implements BasicPlayerListener {
    private PrintStream out = null;

    /**
     * Entry point.
     * 
     * @param args
     *            filename to play.
     */
    public static void main(String[] args) {
        BasicPlayerTest test = new BasicPlayerTest();
        // test.play("src/musica/demo.mp3");

        try {

            // get mp3 path
            String mp3 = "musica/demo.mp3";
            InputStream in = BasicPlayerTest.class.getClassLoader()
                    .getResourceAsStream(mp3);
            test.play(in);

        } catch (Exception e) {
            e.printStackTrace();
            Toolkit.getDefaultToolkit().beep();
            JOptionPane.showMessageDialog(null, "ERROR!" + e,
                    "Simple Player Java", JOptionPane.ERROR_MESSAGE);
        }
    }

    /**
     * Contructor.
     */
    public BasicPlayerTest() {
        out = System.out;
    }

    // public void play(String filename){
    public void play(InputStream filename) {
        // Instantiate BasicPlayer.
        BasicPlayer player = new BasicPlayer();
        // BasicPlayer is a BasicController.
        BasicController control = (BasicController) player;
        // Register BasicPlayerTest to BasicPlayerListener events.
        // It means that this object will be notified on BasicPlayer
        // events such as : opened(...), progress(...), stateUpdated(...)
        player.addBasicPlayerListener(this);

        try {
            // Open file, or URL or Stream (shoutcast, icecast) to play.
            // control.open(new File(filename));
            control.open(filename);

            // control.open(new URL("http://yourshoutcastserver.com:8000"));

            // Start playback in a thread.
            control.play();

            // If you want to pause/resume/pause the played file then
            // write a Swing player and just call control.pause(),
            // control.resume() or control.stop().
            // Use control.seek(bytesToSkip) to seek file
            // (i.e. fast forward and rewind). seek feature will
            // work only if underlying JavaSound SPI implements
            // skip(...). True for MP3SPI and SUN SPI's
            // (WAVE, AU, AIFF).

            // Set Volume (0 to 1.0).
            control.setGain(0.85);
            // Set Pan (-1.0 to 1.0).
            control.setPan(0.0);
        } catch (BasicPlayerException e) {
            e.printStackTrace();
        }
    }

  • Yes it works with Inputstream, an error I noticed is that a bar was missing / in the String mp3 should be String mp3 = "/musica/demo.mp3";

  • ederwander first thank you for your attention, for responding. It is true that the bar was missing yes in this code I posted, but I wanted the problem to be just this one. With the bar typed there also does not work! Error: May 03, 2016 12:48:08 pm javazoom.jlgui.basicplayer.Basicplayer open INFO: open(null) I’m using mp3 inside my application so I need to use Inputstream and not File when indicating the path understand? Look at her documentation there http://www.javazoom.net/jlgui/developerguide.html

  • Very strange does not work with Inputstream this API. Have you used this library before? With FILE works perfectly... Try using that with Inputstream...

  • I think it will be of great help if someone here can make a small example just to show working with Inputstream. Jlayer (jl1.0.1.jar) works perfectly with both File and Inputstream I’ve tried here. Now Basicplayer (basicplayer3.0.jar) has millions of examples on the internet just with File nothing with Inputstream!!! Anyone can help here?

  • Get! player.open(getClass(). getResource("music/vocals.mp3"));
