I know this thread is very old but the provided solution did not work for me and I figured I'd share my solution here...

I added the following dependencies to my pom.xml

   
       org.bytedeco
       ffmpeg
       RELEASE
   

   
   
       org.bytedeco
       javacv-platform
       RELEASE
   

   
   
       org.bytedeco
       javacpp
       RELEASE
   

Then I use ProcessBuilder to execute FFMPEG commands. To merge audio and video, I use the following command:

String ffmpeg = Loader.load(org.bytedeco.ffmpeg.ffmpeg.class);
    try {
        ProcessBuilder pb = new ProcessBuilder(
                ffmpeg,
                "-i",
                [PATH TO AUDIO FILE],
                "-i",
                [PATH TO VIDEO FILE],
                "-acodec",
                "copy",
                "-vcodec",
                "copy",
                [PATH TO OUTPUT FILE]
        );
        
        pb.redirectErrorStream(true);
        Process process = pb.start();
        process.waitFor();

    } catch (IOException | InterruptedException e) {
        e.printStackTrace();
    }
