Xuggler screenRecording code affecting sound recording

I am working on an application for screencast with audio. screen recording with sound is working fine but the issue is that suppose I do recording of 5 mins then generated video file is of 5 min but generated audio file is of 4 min 45 sec. So basically the issue is that both audio and video are not in sync, audio file duration is less as compared to video file.

Both audio and video file recording are running in separate thread but still something is wrong.

VideoCapturing code:

public void run() {
    setVideoParameters();

    FRAME_RATE = frameRate;
    // let's make a IMediaWriter to write the file.
    writer = ToolFactory.makeWriter(movieFile.getName());

    screenBounds = new Rectangle(RecorderSettings.m_CapRectX,
            RecorderSettings.m_CapRecY,
            (int) RecorderSettings.m_CapRectWidth,
            (int) RecorderSettings.m_CapRecHeight);

    // We tell it we're going to add one video stream, with id 0,
    // at position 0, and that it will have a fixed frame rate of
    // FRAME_RATE.

    // ScreenWidth && ScreenHeight multiplied by 3/4 to reduce pixel to 3/4
    // of actual.
    // writer.addVideoStream(0, 0, ICodec.ID.CODEC_ID_MPEG4,
    // screenBounds.width , screenBounds.height );
    writer.addVideoStream(0, 0, vcodec.getID(),
            (screenBounds.width * upperLimit) / lowerLimit,
            (screenBounds.height * upperLimit) / lowerLimit);

    // To have start time of recording
    startTime = System.nanoTime();


    while (isStopProceesBtnClk) {
        try {
            if (!isStopProceesBtnClk) {
                break;
            } else {
                synchronized (this) {
                    while (isPauseProceesBtnClk) {
                        try {
                            // catches starting time of pause.
                            pauseStartTime = System.nanoTime();
                            wait();
                        } catch (Exception e) {

                }


                BufferedImage screen = getDesktopScreenshot();
            // convert to the right image type
                  BufferedImage bgrScreen = convertToType(screen, BufferedImage.TYPE_3BYTE_BGR);


                // encode the image to stream #0
                if (totalPauseTime > 0) {
                    writer.encodeVideo(0, bgrScreen, (System.nanoTime() - startTime)- totalPauseTime, TimeUnit.NANOSECONDS);
                } else {
                    writer.encodeVideo(0, bgrScreen, System.nanoTime() - startTime, TimeUnit.NANOSECONDS);
                }

could someone guide me on this... Thanks.
