I want to keep track of whether auto exposure is set or not. I've tried cap.get (CAP_PROP_AUTO_EXPOSURE); but it always returns -1. I tried cap.set (CAP_PROP_AUTO_EXPOSURE, 0.75) but that doesn't work either. However, when I call the settings window cap.set (CAP_PROP_SETTINGS, 1); auto exposure works. How can I programmatically manage this? I am using Opencv 4.4.0
