I have tested taking snapshot with opencv, so it did not work properly. (opencv ver 4.0.1)
Opencv worked in 3840x2160 good, it did not work in 4208x3120.
VideoCapture::set(cv::CAP_PROP_FRAME_WIDTH, 4208);
VideoCapture::set(cv::CAP_PROP_FRAME_HEIGHT, 3120);
VideoCapture::read();
VideoCapture::imwrite();
I did it with a device (See3CAM_130, https://www.e-consystems.com/13mp-autofocus-usb-camera.asp)
Could I get any help?
