    Description

      In previous versions of iOS, camera resolution could be selected from the QCameraViewfinderSettings and was adjusted accordingly. In iPadOS 13.2 (formerly iOS), when changing resolution from QCameraViewfinderSettings, the active camera resolution remains always the same (1920x1080 in my case, but I don't know if this is device specific). The following minimal working example shows a piece of code probing for available camera resolutions and selecting the highest from the list (in my case 3264x2448 (I'm testing on an iPad 6th Gen, model A1893)). The camera resolution, as seen from a QVideoProbe would be expected to be the same as what was set. It isn't, as can be witnessed from printed debug output. The same example code was ran on iOS 12.4.2 and works as expected, but on 13.2 it doesn't. I do not have access to devices with in between versions (13.0, 13.1) to make more tests and see which version breaks.
