Configuring camera properties in new OCV 2.4.3

Question

I may just be googling wrong, but I cannot find out a way (read function) to change properties of camera in the new Open CV. I need to disable auto exposure

Answer 1

so, there's your VideoCapture:

VideoCapture cap(0);

now you could try to set or get properties:

//may work or not, highly driver/impl specific.
cap.set(CV_CAP_PROP_AUTO_EXPOSURE, 0 ); 
double exposure = cap.get(CV_CAP_PROP_AUTO_EXPOSURE); 

sometimes you can even acces the drivers config dialog this way:

cap.set(CV_CAP_PROP_SETTINGS , 1 );

those constants are in highgui_c.h, around l 333
