QVideoWidget->setBrightness do nothing
I'm developing a software to capture camera.
My problem is that if i want to change brightness (or other of my camera) nothing change and the brightness stay in 0.
viewfinder = new QVideoWidget();
camera = new QCamera(listaCamaras.at(equipo->currentIndex()),this);
For test i use a webcam Hercules classic silver.
Thanks for the help
When i test my webcam with the example of QCamera of Qt i cannot access to take photos or save video and change exposure do nothing.
Maybe the problem is more from the camera ?
And the status of camera is alltime : UnavailableStatus- even the state is ActiveState
I buy a video Grabber USB (ENMVG-3) and i have more problem now.
Each i want to delete the QCamera i obtain a crash. i Tried to use the library OpenCV but when i connect the grabber USB e}and launch the program i obtain e BSOD.
Exist other solutions for capture video, take photos, and record it ?
