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


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 //

Solution

  • 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.
