I want to get/set "Gain" setting for a camera using UWP in code.

I know it is possible to do using WMF(Windows Media Foundation) because in this page
https://learn.microsoft.com/en-us/windows/win32/directshow/configure-the-video-quality#procamp-settings
explains how to do it .

My code:

String ID = "{C6E13360-30AC-11d0-A18C-00A0C9118956} 9";
var property = _mediaCapture.VideoDeviceController.GetDeviceProperty(ID);

Result: $exception {"The data area passed to a system call is too small. (Excep_FromHResult 0x8007007A)"} System.Exception

    From this MS source, the Gain is calculated/set from VideoDeviceController.IsoSpeedControl

    (public float Gain in the source)
