The example in readme doesn't work (Exit code of ffmpeg encoding run is 69)

[kimyuil]

hello.

The example code in the readme is not working properly

I ran the code in spring boot.

pom.xml

<dependency>
      <groupId>ws.schild</groupId>
      <artifactId>jave-all-deps</artifactId>
      <version>3.3.1</version>
    </dependency>

MainApplication.java

try {
      ConvertProgressListener listener = new ConvertProgressListener();

      File source = new File("d:\\wavTest\\piano.wav");
      File target = new File("d:\\wavTest\\piano.mp3");

      AudioAttributes audio = new AudioAttributes();

      audio.setCodec("libmp3lame");
      audio.setBitRate(128000);
      audio.setChannels(2);
      audio.setSamplingRate(44100);

      EncodingAttributes attrs = new EncodingAttributes();
      attrs.setInputFormat("mp3");
      attrs.setAudioAttributes(audio);

      //Encoder encoder = new Encoder();
      Encoder encoder = new Encoder();
      encoder.encode(new MultimediaObject(source), target, attrs, listener);
    }catch (Exception e){
      e.printStackTrace();
    }

ConvertProgressListener.java

public class ConvertProgressListener implements EncoderProgressListener {
  public ConvertProgressListener() {

  }
  public void message(String m) {

  }
  public void progress(int p) {   
    double progress = p / 1000.00;
    System.out.println(progress);
  }
  public void sourceInfo(MultimediaInfo m) {
  }
}

I proceeded with a piano.wav file in the D drive.

By the printStackTrace, I could see the log.

The log "1.0" at the top seems to be caused by the ConvertProgressListener.

I think there is no problem with the wav file. Is there something wrong with the encoding settings? Is my maven installation wrong?

thank you. @a-schild

This looks strange to me, since your source file is wav

attrs.setInputFormat("mp3");

If it still fails, please increase log level, so we see what happens

Thank you! It works.
