You can use the VideoCapture::get. Take a look here. Example of use:

double fps = openedvideo.get(CV_CAP_PROP_FPS)

I think it´s because it is a frame-by-frame acquiring process, so the fps are 0 (-1 in my case). Therefore the question should be: what is the refresh rate? And I need the answer for that question! I think the CV_CAP_PROP_FPS works only while reading a video from a file…
