I was trying out the method of creating a background music for a java program, but it displayed an IO excedption error when i clicked the play button.
package javaentertainment;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.FileInputStream;
import java.io.IOException;
import javax.swing.*;
import sun.audio.AudioData;
import sun.audio.AudioPlayer;
import sun.audio.AudioStream;
public class Music
{
public static void main(String args[])
{
JFrame frame=new JFrame();
frame.setSize(100,100);
JButton button=new JButton("P L A Y");
frame.add(button);
button.addActionListener(new AL());
frame.show();
}
public static class AL implements ActionListener
{
public void actionPerformed(ActionEvent e) {
music();
}
}
public static void music()
{
AudioPlayer MGP=AudioPlayer.player;
AudioStream BGM;
AudioData MD;
ContinousAudioDataStream loop=null;
try
{
BGM = new AudioStream(new FileInputStream("Vision.wmv"));
MD=BGM.getData();
loop=new ContinousAudioDataStream(MD);
}
catch (IOException ex)
{
System.out.println(ex);
}
MGP.start(loop); // word loop was underlined by netbeans
}
}
When I run the program and click on play it displays the following error,
java.io.IOException: could not create audio stream from input stream
You should use JMF (Java Media Framework). For your interest: The list of accepted formats can be found here.
In short, it supports AIFF, AVI, GSM, MVR, MID, MPG, MP2, MOV, AU and WAV files.
But there is a workarond as stated here:
On a side note, if you add a
mime-setting in JMFRegistry to map
Windows Media content (such as .asf
and .wmv) to the content-type
"video/mpeg", JMF can actually play
Windows Media or any other DirectShow
file (and only file - http wont work).
I would be surprised if Java can hand Windows Media format samples - try converting the .wmv to a .wav file and see if it works then.
Just got this, as well.
java.io.IOException: could not create AudioData object
Appears from the source [1] that this means that "your audio file is size > 1 MB" and it doesn't like that for whatever reason. Maybe a bug [?] that they don't accomodate for this.
One work-around might be to use JMF instead, as suggested, if you want looping to work for large files anyway.

I am working on an audio player and need to add pause() and play() features in it to connect with JButtons. The problem is I am not able to import Media package as it says package does not exist. I cannot find anywhere it online to download the package. Same goes for AudioPlayer class which gives bad class file error.
you need the JMF libraries , you can get them from there , for windows there is a typic installer :
JMF Download
Based on your question,
You can down load java.media
then use
import javax.media.*;
then you can declare like
Player audioplayer = Manager.createRealizedPlayer(file.toURI().toURL());
And
audioplayer.start(); and audioplayer.stop();
Here file means where the source file saved.
NB: you can use JMF jar file
Try like this
try {
audioplayer = Manager.createRealizedPlayer(file.toURI().toURL());
} catch (IOException ex) {
Logger.getLogger(MY_MP3_PLAYER.class.getName()).log(Level.SEVERE, null, ex);
} catch (NoPlayerException ex) {
Logger.getLogger(MY_MP3_PLAYER.class.getName()).log(Level.SEVERE, null, ex);
} catch (CannotRealizeException ex) {
Logger.getLogger(MY_MP3_PLAYER.class.getName()).log(Level.SEVERE, null, ex);
}
OR Try the sample code given below
import java.io.File;
import java.io.IOException;
import java.util.Scanner;
import javax.media.CannotRealizeException;
import javax.media.Manager;
import javax.media.NoPlayerException;
import javax.media.Player;
public class Mp3Player {
public static void main(String[] args) throws IOException, NoPlayerException, CannotRealizeException {
// Source of song file
File f=new File("your path in which mp3 file is saved");
// Create a Player object that realizes the audio
final Player p=Manager.createRealizedPlayer(f.toURI().toURL());
// Start the music
p.start();
// Create a Scanner object for taking input from cmd
Scanner s=new Scanner(System.in);
// Read a line and store it in st
String st=s.nextLine();
// If user types 's', stop the audio
if(st.equals("s"))
{
p.stop();
}
}
}
It is a late answer, but you can use the Maven dependency:
<!-- https://mvnrepository.com/artifact/javax.media/jmf -->
<dependency>
<groupId>javax.media</groupId>
<artifactId>jmf</artifactId>
<version>2.1.1e</version>
</dependency>
Following four packages will solve your problem. They contains most of helpful methods to deal with audio player.
import javazoom.jl.decoder.JavaLayerException;
import javazoom.jl.player.AudioDevice;
import javazoom.jl.player.FactoryRegistry;
import javazoom.jl.player.advanced.AdvancedPlayer;
You can use .stop(), start(), .play() etc. from above packages.
Hope that will help.

I need some help adding music to jframe. i been looking only for a good tutorial, and none of them seem to work.
im using netbeans. here is my current code. i just want to add music to the frame no stop button for now. Thank you.
Have a look at Accessing Audio System Resources. Here are the available classes
Class Format
---------------------------------------------
AudioSystem WAV
Manager* MP3
MidiSystem Midi
javax.media.Manager requires Java Media Framework
The easiest options are AudioSystem or MidiSystem a they require no additional JAR files. Here is an example from the javasound tag link
public class LoopSound {
public static void main(String[] args) throws Exception {
URL url = new URL(
"http://pscode.org/media/leftright.wav");
Clip clip = AudioSystem.getClip();
// getAudioInputStream() also accepts a File or InputStream
AudioInputStream ais = AudioSystem.getAudioInputStream( url );
clip.open(ais);
clip.loop(Clip.LOOP_CONTINUOUSLY);
SwingUtilities.invokeLater(new Runnable() {
public void run() {
// A GUI element to prevent the Clip's daemon Thread
// from terminating at the end of the main()
JOptionPane.showMessageDialog(null, "Close to exit!");
}
});
}
}
To integrate the the audio with the JFrame, simply invoke Clip#loop when the application is started.
Try:
public static void playSong(URL media) {
Player mediaPlayer = Manager.createRealizedPlayer(media);
mediaPlayer.start()
}
So you should just be able to call that method and pass in the URL to the media, and then it should play (Note: I have not tested this code).
The imports you need are:
import javax.media.Player;
import java.net.URL;
I just remembered, you need to add the JMF .jar to your project. The JMF (Java Media Framework) has tools for playing music and (I think) video, among other things.
Here is a pretty extensive tutorial from IBM: http://www.ibm.com/developerworks/java/tutorials/j-jmf/
Towards the bottom, it has instructions on installing JMF, and then on the next page it shows you how to make basic audio.
Some more advice:
1) You need to add the mp3 plug in to play mp3s from the JMF. After adding the plug in .jar file to your project, this is the code you haft to add (I'm doing this from memory, so it may be wrong):
Format input1 = new AudioFormat(AudioFormat.MPEGLAYER3);
Format input2 = new AudioFormat(AudioFormat.MPEG);
Format output = new AudioFormat(AudioFormat.LINEAR);
PlugInManager.addPlugIn(
"com.sun.media.codec.audio.mp3.JavaDecoder",
new Format[]{input1, input2},
new Format[]{output},
PlugInManager.CODEC
);
2) The last time I used it, the JMF download link was broken on the oracle website (it linked to the wrong page), so you may have to search around for the link on google.
I apologize for the long question.
I was browsing a forum the other day and I saw a few pieces of text that were linking to youtube and other sites.
I had to always highlight and then copy and paste or right click "go to" in google chrome browser.
Since I've been playing with Java a little bit, I thought about making my own little program that will give a link to text that has an address . For example if I said "hey, check this video out I saw the other day 'www.youtube.com' " I'd want the youtube part to be clickable.
Could anybody tell me if such a thing is possible and if it is, what libraries would I have to use for this and lastly, how can I find a list of all imports and libraries in java?
Thanks.
Use HTML in JEditorPane and add HyperLinkListener to detect click on URLs.
Than use Desktop API to open default browser with the URL.
Something like:
import java.awt.Desktop;
import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;
import javax.swing.event.HyperlinkEvent;
import javax.swing.event.HyperlinkListener;
public class Test {
public static void main(String[] argv) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
JEditorPane jep = new JEditorPane();
jep.setContentType("text/html");//set content as html
jep.setText("Welcome to <a href='http://stackoverflow.com/'>StackOverflow</a>.");
jep.setEditable(false);//so its not editable
jep.setOpaque(false);//so we dont see whit background
jep.addHyperlinkListener(new HyperlinkListener() {
#Override
public void hyperlinkUpdate(HyperlinkEvent hle) {
if (HyperlinkEvent.EventType.ACTIVATED.equals(hle.getEventType())) {
System.out.println(hle.getURL());
Desktop desktop = Desktop.getDesktop();
try {
desktop.browse(hle.getURL().toURI());
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
});
JFrame f = new JFrame("HyperlinkListener");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.add(jep);
f.pack();
f.setVisible(true);
}
});
}
}
I am making a card game, and it's almost done. The last thing I want to do is play some background music. Now if I copy the file into the default package and make a single jar file of the game, will the music play on all computers? Currently, on my PC it's running without any problem by giving a specific path for the file like "C:\\samp.wav";. But I am worried that if I make a jar file and run it on another PC it won't work properly. I think there will be a FileNotFoundException. Am I right or wrong?
For the card's image I am using this line:
jLabel1.setIcon(new javax.swing.ImageIcon(getClass().getResource("/1.jpg")));
Those pictures I have inserted into my default package. I want to do the same for the music file, but how? I am using NetBeans.
You should include the wav file inside your application jar. This way you won't have to manage the copy of the file in the user's file system (keep in mind that, for example, in UNIX, Mac, etc. you can't access to the hard drive through C:/...).
For example, if you place the wav file in the root of the app jar (app.jar/samp.wav):
InputStream is = getClass().getClassLoader().getResourceAsStream("samp.wav");
or, if you had a "sounds" directory in the app jar root (app.jar/sounds/samp.wav):
InputStream is = getClass().getClassLoader().getResourceAsStream("sounds/samp.wav");
Check this post for extra information about playing wav files with Java (though for your question, I think you have already solved this problem). Consider as well playing it in a separate thread. Check also this web for examples about managing media files in Java.

I am wanting to make a simple java applicaiton to play video. I want it to play mpeg4 and mov formats in particular. JMF is what I started with and I have a lovely working example. However, there is no support for mov or mpeg4 formats. I've looked at Xuggler but can't see a SIMPLE way to get it working. VLCJ seemed easy - I downloaded the jar files and attached them to my project (vlcj-2.1.0.jar, jna-3.4.0.jar, platform-3.4.0.jar, vlcj-2.1.0.jar)). I got the sample code and adapted it (below). But when I run the code, I get a java.lang.NullPointerException exception. I've tried adjusting the number and direciton of the slashes (forward and backward) in the filename. Nothing seems to work. Please could you help???

I'm using VLC version 2.0.2 and VLCJ 2.1.0 sources and JDK 1.7 on windows 32 bit. I hope it's something simple...
It looks like you are using mediaPlayerwithout ever initializing it, thus causing a NullPointerException in run().
Try initializing it in your constructor.
