Linux下Java中使用ffmpeg将amr转换为mp3失败

linux下安装ffmpeg完成后，Java依然无法将amr转换为MP3

这个问题困扰我三天了，还请各位不吝赐教

1、程序中转换的代码

img

public void changeToMp3(String sourcePath, String targetPath) {
        File source = new File(sourcePath);
        File target = new File(targetPath);
        AudioAttributes audio = new AudioAttributes();
        Encoder encoder = new Encoder();

        audio.setCodec("libmp3lame");
        EncodingAttributes attrs = new EncodingAttributes();
        attrs.setFormat("mp3");
        attrs.setAudioAttributes(audio);

        try {
            encoder.encode(source, target, attrs);
        } catch (Exception e) {
            log.info("changeToMp3-amr转换mp3异常：",e);
        }
    }

## 添加的依赖
<dependency>
            <groupId>it.sauronsoftware</groupId>
            <artifactId>jave</artifactId>
            <version>1.0.2</version>
        </dependency>
    </dependencies>

2、安装的ffmpeg

Use -h to get full help or, even better, run 'man ffmpeg'

3、使用命令可以成功转换

[msun@chis-test-interhospita-02 tmp]$ ffmpeg -i /tmp/tomcat-docbase.5368136354015673121.10001//8a6ca3c0b713462bafb496fecbb16935.amr /tmp/test1.mp3

并且转换后的mp3文件可以正常播放

4、Java程序中报的错

安装ffmpeg以前也是报这个错，安装成功后还是报这个错，一开始我以为安装失败了，重装了三次，依然不行，但是命令能够转换成功，我就不认为是安装失败了呢。

    直接调用命令行把，java依赖的jar jave-1.0.2.jar 是内置了一个ffmpeg的，可以解压依赖的jar，看到里面存在一个ffmpeg，这个版本比较老，支持的参数也不一样。
