Note AMCap source comment: // we use this interface to bring up the 3 dialogs Then I doubt that AMCap uses exactly the code path you mentioned in the question. Presumably you interact with cameras via DirectShow (well, it does not make much sense to use VFW, esp. If it is DirectShow then you are basically not interested in VFW dialogs. If it is Video for Windows, then you should look into VFW API on dialog interface. In your Qt/OpenCV application what is the API used and what exactly you have for given web camera.

In opencv just camera index is used to select proper camera. Can you help me to get this code working for given webcam (multiple camera support is required)? I use Qt and OpenCV while working with camera.
For now, I found out that the dialog is from vfw and it can be activated from dshow api. I want to allow the user to change camera settings (VfwCaptureDialog_Source) as it is common in skype or amcap application.

I am doing a windows based app where I use a camera.
