I open a video file and get its frame rate by capture.get(CV_CAP_PROP_FPS). But it differs from the actual frame rate stated in the property of the video file. I would be grateful if any can help. regards

The parameter you are reading out is the FPS that the capture algorithme can reach to read out frames of a videofile, not the framerate of the actual video. It all depends on resources, system configuration, and so on.
