JMF is not required to get the MP3 plugin to work with JavaSound.
The problem I think you will find is that MP3 plugin does not play
all of the formats that exist.
The only format I'm trying to play is MP3.
It too is pretty old and has not been updated in several years. The
tritonus libraries might be a better option but I'm not an MP3 expert.
Didn't we get here when the tritonus libraries just plain didn't
work? (And yes I did try adding each separate tritonus jar to the
classpath, AND I tried dropping them all in the same ext dir where
the Sun mp3 plugin installer dropped a file named mp3plugin.jar when
I ran it.)
MP3 is not a single format. That's where the problem lies I'm pretty
sure.
knute...
This is leading nowhere.
Lay it down for me: a simple, step-by-step installation procedure that
starts with downloading one or more jars or installers from a web site
and ends with mp3 support in Java that actually works, and works reliably.
Thank you.
OK.
1) On Windows, go download the javamp3-1_0.exe file and install it.
2) Go rip a CD with Windows Media Player into MP3 format.
3) Use this code to play your MP3 file.
import java.io.*;
import javax.sound.sampled.*;
public class Play {
public static void main(String[] args) {
class MyLineListener implements LineListener {
public void update(LineEvent le) {
LineEvent.Type type = le.getType();
System.out.println(type);
}
};
try {
AudioInputStream fis =
AudioSystem.getAudioInputStream(new File(args[0]));
System.out.println("File AudioFormat: " + fis.getFormat());
AudioInputStream ais = AudioSystem.getAudioInputStream(
AudioFormat.Encoding.PCM_SIGNED,fis);
AudioFormat af = ais.getFormat();
System.out.println("AudioFormat: " + af.toString());
int frameRate = (int)af.getFrameRate();
System.out.println("Frame Rate: " + frameRate);
int frameSize = af.getFrameSize();
System.out.println("Frame Size: " + frameSize);
SourceDataLine line = AudioSystem.getSourceDataLine(af);
line.addLineListener(new MyLineListener());
line.open(af);
int bufSize = line.getBufferSize();
System.out.println("Buffer Size: " + bufSize);
line.start();
byte[] data = new byte[bufSize];
int bytesRead;
while ((bytesRead = ais.read(data,0,data.length)) != -1)
line.write(data,0,bytesRead);
line.drain();
line.stop();
line.close();
} catch (Exception e) {
System.out.println(e);
}
}
}
It will also play with this JMF video player code as well;

Then try it with the file you really want to play. If it doesn't work
(here we go again) that's because it won't play every MP3 formatted file.
