Change Callback For Camera

imageConverter = new Runnable() {
    @Override
    public void run() {
        ImageUtils.convertYUV420SPToARGB8888(bytes, previewWidth, previewHeight, rgbBytes);
    }
};

postInferenceCallback = new Runnable() {
    @Override
    public void run() {
        camera.addCallbackBuffer(bytes);
        isProcessingFrame = false;
    }
};

how to give bytes from uvc camera and also how to code instead of camera.addCallbackBuffer(bytes);
