You can use a library called JAVE (Java Audio Video Encoder) to encode a video into an audio file.

Download JAVE from here.
Refer to the below snippet to encode from MP4 to MP3

Code:

File source = new File("source.mp4");
File target = new File("target.mp3");

AudioAttributes audioAttributes = new AudioAttributes();
audioAttributes.setCodec("libmp3lame")
    .setBitRate(new Integer(128000))
    .setChannels(new Integer(2))
    .setSamplingRate(new Integer(44100));
EncodingAttributes encodingAttributes = new EncodingAttributes();
encodingAttributes.setFormat("mp3")
    .setAudioAttributes(audioAttributes);

Encoder encoder = new Encoder();
encoder.encode(source, target, encodingAttributes);
