oh i almost forgot , my OS is win 8 and here's the code 
FrameGrabber grabber1 = new FFmpegFrameGrabber("Fifteen.mp4");
        grabber1.start();
        FrameGrabber grabber2 = new FFmpegFrameGrabber("Six.mp4");
        grabber2.start();
        FrameRecorder recorder = new FFmpegFrameRecorder(
                "output.mp4",grabber1.getImageWidth(),grabber1.getImageHeight());
        try {
            recorder.start();
            Frame frame;
            while ((frame = grabber1.grabFrame()) != null) {
                recorder.record(frame);
            }
            while ((frame = grabber2.grabFrame()) != null) {
                recorder.record(frame);
            }
            recorder.stop();
            grabber2.stop();
            grabber1.stop();

Please try to include the JAR files ending with "Windows-x86.jar" as well.

Good to hear that! 

To merge a third video, add "FrameGrabber grabber3 = new 
FFmpegFrameGrabber(...)", and a fourth, etc. We can merge as many videos as one 
wishes. 

Please ask your questions on the mailing list next time if possible, thank you!
