I am currently working on Windows application which is supposed to record video from two webcams simultaniously and save it as one videofile. I struggle with code implementation. It is prefered to use only QT classes.

I have managed to retrieve videoframes as QImage object to combine them, but then I did not fint a way so save a sequence of QImages as a video using only QT classes.
I have already done similar project using OpenCV, which seemed easier. However, I would like to implement this using QT since it has access to camera device name, unlike OpenCV.
