You can use OpenCV's API to get the original FPS if you are dealing with video files. The following method will not work when capturing from a live stream:

cv::VideoCapture capture("C:\\video.avi");
if (!capture.isOpened())
{
    std::cout  << "!!! Could not open input video" << std::endl;
    return;
}

std::cout << "FPS: " << capture.get(CV_CAP_PROP_FPS) << std::endl;

To get the actual FPS after the processing, you can try Zaw's method.
