Play/load mp3 using Java APIs and JMF, error unsupported format

Question

I am trying to load a MP3 file. I have jmf.jar (windows version) in my classpath and am trying to run my class through Eclipse. But I get this error when trying to run.

I downloaded and set this version of JMF from the oracle site:

JMF2.1.1e\lib

I am running with Java 7 from Oracle (through Eclipse)

Error:

 javax.sound.sampled.UnsupportedAudioFileException: 
    could not get audio input stream from input stream  
    at  
 javax.sound.sampled.AudioSystem.getAudioInputStream
    (Unknown Source)
    at
 org.berlin.sound.WaveformDisplaySimulator.main
    (WaveformDisplaySimulator.java:47)

Here is the code:

import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;

import javax.media.Codec;
import javax.media.Format;
import javax.media.PlugInManager;
import javax.media.format.AudioFormat;
import javax.sound.sampled.AudioFileFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;


    public static void main(final String[] args) {
        try {

            System.out.println(System.getProperty("java.version"));
            final String MP3 = "com.sun.media.codec.audio.mpa.JavaDecoder";
            Codec mp3 = (Codec) Class.forName(MP3).newInstance();

            final Format input1 = new AudioFormat(AudioFormat.MPEGLAYER3);
            final Format input2 = new AudioFormat(AudioFormat.MPEG);
            final Format output = new AudioFormat(AudioFormat.LINEAR);
            PlugInManager.addPlugIn(
                "com.sun.media.codec.audio.mpa.JavaDecoder",                
                new Format[]{ input1, input2 },
                new Format[]{ output },
                PlugInManager.CODEC
            );

            final AudioFileFormat.Type [] types = AudioSystem.getAudioFileTypes();
            for (final AudioFileFormat.Type t : types) {
                System.out.println("Returning Type : " + t);
            } // End of the for //


            final String PATH = "C:\\Users\\Downloads\\soundcloud2.mp3"; 
            final File file = new File(PATH);
            final AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new BufferedInputStream(new FileInputStream(file)));

        } catch (final Exception e) {
            e.printStackTrace();
        }
    } // End of the method //

Have you got the MP3 Library plugin as well? http://www.oracle.com/technetwork/java/javase/download-137625.html — Philip Whitehouse, Oct 20 '12 at 00:29
`could not get audio input stream from input stream` Not all MP3s are equal. Try it with other MP3s, particularly old/simple ones as might be found [here](http://pscode.org/media/#sound) (the page is slow at the moment). — Andrew Thompson, Oct 20 '12 at 00:54
I don't see the mp3plugin.jar. When I click on that link above, I get redirected to the JMF download site which doesn't specifically have the mp3plugin. Also, I rand JMStudio and was able to load the MP3. So it must be my code. I don't know what to change. Also, the JavaDecoder class is not in my classpath, I can't find it. — Berlin Brown, Oct 20 '12 at 01:02
I couldn't get the oracle downloads to work. I downloaded this mp3plugin and it worked without any code changes. Strange that the oracle files wouldn't work. Apparently they may be patent issues with the mp3 drivers? http://www.tritonus.org/plugins.html — Berlin Brown, Oct 21 '12 at 00:01

I never could get the oracle download to work. I ended up downloading a MP3 plugin from this site and then adding the plugin in my classpath. This worked with Eclipse and without.

Also, I didn't have to modify my code. I was able to read the mp3 binary data and also stream to output.

        System.out.println("Running");        
        System.out.println(System.getProperty("java.version"));        
        final AudioFileFormat.Type [] types = AudioSystem.getAudioFileTypes();
        for (final AudioFileFormat.Type t : types) {
            System.out.println("Returning Type : " + t);
        } // End of the for //                
        final String PATH = "C:\\Users\\bbrown\\Downloads\\swing-hacks-examples-20060109\\Ch10-Audio\\75\\soundcloud2.mp3";             
        final File file = new File(PATH);
        final AudioInputStream in = AudioSystem.getAudioInputStream(new BufferedInputStream(new FileInputStream(file)));

        AudioInputStream din = null;
        final AudioFormat baseFormat = in.getFormat();
        final AudioFormat decodedFormat = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED,
                baseFormat.getSampleRate(),
                16,
                baseFormat.getChannels(),
                baseFormat.getChannels() * 2,
                baseFormat.getSampleRate(),
                false);

        System.out.println("Channels : " + baseFormat.getChannels());                
        din = AudioSystem.getAudioInputStream(decodedFormat, in);        
        rawplay(decodedFormat, din);
        in.close();       
        System.out.println("Done");
    }

AudioInputStream can't open mp3 format sounds cause they are compressed , even if you format them as PCM_SIGNED like wav files they can't be played always . You may like jLayer , I have never seen it to crash

import javazoom.jl.player.advanced.AdvancedPlayer;

`

            try{
            File file = new File("C:/DMK.mp3");
            FileInputStream in = new FileInputStream(file);
            AdvancedPlayer player = new AdvancedPlayer(in);
            player.play();
        } 
        catch (Exception ex) {
            ex.printStackTrace();
        }

It's 2017, and I added support for mp3 encoding/decoding by using the mp3spi package (http://www.javazoom.net/mp3spi/mp3spi.html)

Somebody was kind enough to set it up as a dependency on Google Code. Here's the gradle entry:

compile group: 'com.googlecode.soundlibs', name: 'mp3spi', version: '1.9.5-1'

So this or the maven equivalent should give you mp3 support in your project.
