Question

在下面的代码中，我想使用JMF库播放mp3音乐文件。我已下载mp3.plugIn并将其添加到我的项目中。

package mediaaa;

import java.io.File;
import java.io.IOException;


import javax.media.*;
import javax.media.format.AudioFormat;
import javax.media.pim.PlugInManager;

       public class Mediaaa {

               public static void main(String[] args) {

       File file = new File("C:\\Users\\Jovan\\Desktop\\music.mp3");

    try {

        Format inputMP3 = new AudioFormat(AudioFormat.MPEGLAYER3);
        Format inputMPEG = new AudioFormat(AudioFormat.MPEG);
        Format output = new AudioFormat(AudioFormat.LINEAR);

        PlugInManager.addPlugIn("com.sun.media.codec.audio.mp3.JavaDecoder", new Format[] { inputMP3, inputMPEG },
                new Format[] { output }, PlugInManager.CODEC);

        Player player = Manager.createRealizedPlayer(file.toURI().toURL());

        player.start(); // Without this code works but there is no sound

    } catch (NoPlayerException | IOException | CannotRealizeException e) {
        e.printStackTrace();
    }

}

}

运行代码时出现此错误：

java.lang.ArrayIndexOutOfBoundsException: -2
at codecLib.mp3.i.a(Unknown Source)
at codecLib.mp3.i.char(Unknown Source)
at codecLib.mp3.Decoder.decode(Unknown Source)

有谁知道如何修复它？

是什么导致JMF中的数组错误
