video show and write keeping original fps
When the video write, we can set parameter in following function..
outVideo.open(".\\outVideo.avi", askFileTypeBox, capture.get(CV_CAP_PROP_FPS), S, Color);
And we can control play speed by waitKey.
double fps = capture.get(CV_CAP_PROP_FPS);
delay Per Second = 1/fps
in milliseconds = 1/fps * 1000
so we delay, waitKey( 1/fps * 1000 )
by the way, it is not exact fps. because it is delayed including other processing in the loop.
for example, data copy, sobel, imshow ...
