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);
