Javacv: How to convert .wav to .m4a with ffmpeg

[jeketos]

Hello. I have some problem. I need to convert audio file using ffmpeg. How i can do it programmatically?

The most basic example would be something like this:

    FFmpegFrameGrabber grabber = new FFmpegFrameGrabber("in.wav");
    grabber.start();

    FrameRecorder recorder = new FFmpegFrameRecorder("out.mp4", grabber.getAudioChannels());
    recorder.setSampleRate(grabber.getSampleRate());
    recorder.start();

    Frame frame;
    while ((frame = grabber.grabFrame()) != null) {
        recorder.record(frame);
    }
    recorder.stop();
    grabber.stop();
