capDriverGetCaps macro (vfw.h)
The capDriverGetCaps macro returns the hardware capabilities of the capture driver currently connected to a capture window. You can use this macro or explicitly send the WM_CAP_DRIVER_GET_CAPS message.

hwnd,
s,
wSize
);
hwnd
Handle to a capture window.
s
Pointer to the CAPDRIVERCAPS structure to contain the hardware capabilities.

The capabilities returned in CAPDRIVERCAPS are constant for a given capture driver. Applications need to retrieve this information once when the capture driver is first connected to a capture window.
