![]() Refer to the Extension Unit Plug-In Architecture topic for more information on how the sample code modules work together. Supporting Autoupdate Events with Extension Units Sample Application for UVC Extension Units (contains TestApp.cpp) Sample Registry Entry for UVC Extension Units (contains Xusample.rgs) Sample Extension Unit Plug-in DLL (contains Xuproxy.h and Xuproxy.cpp) Sample Interface for UVC Extension Units (contains Interface.idl) This topic contains information on creating the required project files and provides links to sample code in the following topics: To build a UVC extension unit for your device, follow the instructions in Building the Extension Unit Sample Control. Tag the illumination flag in the DeviceMFT componentĬonvert the IKSControl in the DeviceMFT component to communicate with the UVC extension unit you will build in the next section:īuild a USB Video Class (UVC) Extension Unit To modify the driver sample, make the following changes to the sample source code:Īdd Source type information in the DeviceMFT component Configure the DeviceMFT componentĪs a starting point for building a DeviceMFT component that supports face authentication on your device, you can use the sampledevicemft sample. To enable face authentication for an infrared camera on your device, you must provide a correctly configured DeviceMFT component and USB Video Class (UVC) extension unit. For more information, see the mandatory metadata attributes table in the Capture Stats Metadata Attributes topic. This metadata attribute for IR cameras specifies that frames are using active IR illumination. KSCAMERA_EXTENDEDPROP_FACEAUTH_MODE_BACKGROUND_SUBTRACTIONįor more information about this control and how to use the bit flags to set the face authentication mode, see the KSPROPERTY_CAMERACONTROL_EXTENDED_FACEAUTH_MODE topic. KSCAMERA_EXTENDEDPROP_FACEAUTH_MODE_ALTERNATIVE_FRAME_ILLUMINATION KSCAMERA_EXTENDEDPROP_FACEAUTH_MODE_DISABLED ![]() This property ID is used to turn on and configure face authentication in the driver using the following flags: There are two new face authentication DDI constructs available in Windows 10, version 1607 to support Windows Hello: The following diagram shows how face authentication works with the new driver stack through FrameServer: This topic discusses how to enable face authentication for an infrared (IR) camera and is meant for original equipment manufacturers (OEMs) and independent hardware vendors (IHVs) who want to provide this functionality in their devices. ![]()
