Enabling Video Overlay

The following example uses the capDriverGetCaps macro to determine whether a capture driver has overlay capabilities; if it does, the macro enables the overlay.

CAPDRIVERCAPS CapDrvCaps; 

capDriverGetCaps(hWndC, &CapDrvCaps, sizeof (CAPDRIVERCAPS)); 

if (CapDrvCaps.fHasOverlay) 
    capOverlay(hWndC, TRUE);
