Changing video settings

Hi All.

I would like to change some video settings such as focus, autoexposure, autofocus, contrast, brightness etc programatically.
In open cv we have capture.set(CV_CAP_PROP_xxxx,value);
where VideoCapture capture;

But openframeworks appears much more stable when using 3 or more cameras, so I would like to use openframeworks.
How can I set these properties in openframeworks?

I’ve been looking for this solution as well. If anyone has suggestion, feel free to advise. Thank you
