My camera application on Windows Mobile5.0 is not calling the overlay
related driver functions like SetOverlayPos() and UpdateOverlay().
And I do have HW overlay support both in my driver and HW as well.
And I am setting the overlay caps structure with the following flags in

the buildDDHALInfo () function() of my DDRAW enabled display driver.
lpddhi->ddCaps.dwOverlayCaps = DDOVERLAYCAPS_FLIP
|
DDOVERLAYCAPS_MIRRORLEFTRIGHT |
DDOVERLAYCAPS_MIRRORUPDOWN |
DDOVERLAYCAPS_CKEYSRC |
DDOVERLAYCAPS_CKEYDEST |

DDOVERLAYCAPS_OVERLAYSUPPORT;


So Would anyone tell me why the above functions are not getting called
even though I seem to have done everything right.


Thanks
