Terminology KeywordDriver Update the device, you a project to update the. This document outlines how to expose certain capabilities of a UVC compliant camera to the applications through the inbox driver. This driver supports color and sensor type cameras. As this is a beta release, please refer to the forum and release notes for tips and tricks.Windows 10 provides an inbox USB Video Class (UVC) driver for devices compliant with USB Video Class specification (versions 1.0 to 1.5).We recommend the camera firmware specify a value based on which the UVC driver would register the camera under one or both supported categories.A camera that supports color only format types should be registered under KSCATEGORY_VIDEO_CAMERA. The UVC driver supports both types of cameras. RGB or YUV cameras are categorized as color cameras and non-color cameras like gray scale, IR and Depth cameras are categorized as sensor cameras. One is a color camera and the other one is a non-color sensor camera. I recently bought some WinBook WB-7144 HD webcams from microcenter at 30.The camera that outputs color streams (for example, RGB or YUV cameras)The camera that outputs non-color streams (for example, IR or Depth cameras)Microsoft platform specific BOS device capability descriptorWindows supports two categories of cameras. ![]() This type maps to MFVideoFormat_L8.Uncompressed 16 bit luma plane. IR streamThe Windows inbox USB video class (UVC) driver supports cameras that capture the scene in YUV format and transmit the pixel data over USB as uncompressed YUV or as compressed MJPEG frames.The following format type GUIDs should be specified in the stream video format descriptor, as defined in the WDK ksmedia.h header file: TypeUncompressed 8 bit luma plane. Refer to the Example composite device section below for a sample BOS descriptor with a platform specific MS OS 2.0 descriptor.If you cannot update the device firmware as described above, you can use a custom INF and specify that your camera need to be registered as a sensor camera by specifying a value for SensorCameraMode and SkipCameraEnumeration as follows:A custom INF file (based on the inbox UVC driver) must include the following AddReg entries:SensorCameraMode: REG_DWORD: 1 (to register as a sensor camera)SkipCameraEnumeration: REG_DWORD: 1 (make it available only for IR applications)An example of the custom INF section is as follows: HKR, SensorCameraMode, 0x00010001,1 places the value under device HWHKR, SkipCameraEnumeration, 0x00010001,1 This makes the camera availableIf the SensorCameraMode and SkipCameraEnumeration attributes are not specified in the firmware or the INF, the camera will be registered as a color camera and will be visible only to color camera aware applications. Can adobe suite for mac be used on a pc// Example Format Descriptor for UVC 1.1 frame based formatGUID guidFormat // this field should contain the IR subtype GUID} VIDEO_FORMAT_FRAME, *PVIDEO_FORMAT_FRAME IR streams will show up as regular capture streams in DShow. No scaling or conversions of the IR frames are supported by the pipeline for IR streams.A stream exposing IR format types must not expose RGB or Depth format types. Applications written with Media Foundation FrameReader API will be able to consume the IR stream. Media Foundation converts this into NV12 uncompressed frames and uses only the luma plane.When these format type GUIDs are specified in the guidFormat field of the frame descriptor, the Media Foundation capture pipeline marks the stream as IR stream. No scaling or conversions of the depth frames are supported by the pipeline for depth streams.A stream exposing Depth format types must not expose RGB or IR format types. Applications written with FrameReader API will be able to consume the depth stream. The values are in millimeters.When the format type GUID is specified in the guidFormat member of the frame descriptor, the Media Foundation capture pipeline marks the stream as depth stream. This type is identical to MFVideoFormat_D16. The following format type GUID should be specified in the stream video format descriptor, as defined in the WDK ksmedia.h header file: Type16 bit depth map values. These cameras capture the depth information (For example, time of flight) of the scene and transmit the depth map as uncompressed YUV frames over USB. This will make applications like Windows Hello to make use of the related cameras for their scenarios.The relation between the camera functions could be specified in the camera's BOS descriptor in firmware. For example, an IR camera and a Color camera present on the same physical device can be exposed to the OS as related cameras. Grouping camerasWindows supports grouping of cameras based on their container ID to aid applications work with related cameras. Specify its value using the BOS descriptor. To make the OS take advantage of the device's Method 2/3 still image capture support, through UVC driver, the device firmware could specify a value in the BOS descriptor.The value to specify to enable Method 2/3 still image capture is a DWORD named UVC-EnableDependentStillPinCapture. Method 2 or Method 3 still capture supportUVC specification does provide a mechanism to specify if the video streaming interface supports Method 1/2/3 type still image capture. The custom INF file (based on the inbox UVC driver) must include the following AddReg entries:FSSensorGroupID: REG_SZ: ""FSSensorGroupName: REG_SZ: "your sensor group friendly name"An example for the custom INF section would be as follows: AddInterface=%KSCATEGORY_CAPTURE%,GLOBAL,USBVideo.InterfaceAddInterface=%KSCATEGORY_RENDER%,GLOBAL,USBVideo.InterfaceAddInterface=%KSCATEGORY_VIDEO%,GLOBAL,USBVideo.InterfaceAddInterface=%KSCATEGORY_RENDER_EXT%,GLOBAL,USBVideo.InterfaceAddInterface=%KSCATEGORY_VIDEO_CAMERA%,GLOBAL,USBVideo.InterfaceHKR, FSSensorGroupID,0x00000000,%FSSensorGroupID%HKR, FSSensorGroupName,0x00000000,%FSSensorGroupName%Sensor Groups are not supported in DShow capture pipeline. The cameras that have the same UVC-FSSensorGroupID will be grouped together.The sensor group can be given a name by specifying UVC-FSSensorGroupName, a Unicode string, in the firmware.Refer to the Example composite device section below for an illustrative example BOS that specifies UVC-FSSensorGroupID and UVC-FSSensorGroupName.If you cannot update the device firmware as described above, you can use a custom INF and specify that your camera is part of a sensor group by specifying a sensor group ID and name as follows. This will make the OS camera stack expose them as a related group of cameras to the applications.The camera firmware must specify a UVC-FSSensorGroupID, which is a GUID in string form with the curly parenthesis.
