KSPROPERTY_CAMERACONTROL_EXTENDED_FIELDOFVIEW2_CONFIGCAPS

  • Cikk

KSPROPERTY_CAMERACONTROL_EXTENDED_FIELDOFVIEW2_CONFIGCAPS is a property ID that allows camera drivers to offer multiple fixed field of view (FoV) settings that users can select through the Camera settings page or applications.

  • Field of View values reported in the KSPROPERTY_CAMERACONTROL_EXTENDED_FIELDOFVIEW2_CONFIGCAPS payload array must be sorted in descending order, for example, largest value first.

  • All Field of View (FoV) values reported by KSPROPERTY_CAMERACONTROL_EXTENDED_FIELDOFVIEW2_CONFIGCAPS must be supported on all available media types that the driver chooses to support.

    • Drivers can do scaling and/or cropping to achieve FoVs on certain resolutions.

    • Exceptions can be made by supporting Camera Profiles and adding KSPROPERTY_CAMERACONTROL_EXTENDED_FIELDOFVIEW2 as BlockedControl. This will result in that the FIELDOFVIEW2 control is not supported at all when a profile that blocks it is used.
