UVC CAMERA CONTROL DRIVER
The custom INF file, based on either custom UVC driver or inbox UVC driver, should include the following AddReg entry:ĮnableDependentStillPinCapture: REG_DWORD: 0x0 (Disabled) to 0x1 (Enabled)
UVC CAMERA CONTROL WINDOWS
Note: The camera driver can be based on the Windows USBVIDEO.SYS or can be based on a custom driver binary. In Windows 10, version 1703, devices that leverage this method must use a custom INF file for the camera driver, but a custom INF is required for the given hardware to enable Method 2 still image capture).

In Windows 10, version 1607 and earlier, the capture pipeline did not leverage Method 2, even if a device advertised support for it per the UVC 1.5 spec. Some existing UVC devices may not support Method 2 described in section 2.4.2.4 (Still Image Capture) of the UVC 1.5 Class specification.pdf that can be downloaded at the USB Video Class specification web site. 2 Architectural Overview 2.1 Description 2.2.1 Capability discovery through INF 2.2.1.1 Still Image Capture – Method 2 VRAM or DX surfaces will not be supported. UVC metadata will only support system allocated memory. Every IHV/OEM that needs metadata support must enable this through a custom INF file. UVC metadata support will be available only through the Media Foundation (MF) capture pipeline. UVC metadata support will be only available to frame based payloads.

However, in the case of BULK endpoint, the metadata size will be limited to 240 bytes (due to the fact that all video frame data is transferred in a single video frame packet on BULK endpoints). The USB Video Class (UVC) frame metadata support will be available to ISOCH and BULK endpoints. Microsoft extensions to the USB Video Class specification enable new controls as well as the capability to carry well-defined frame-metadata in a standard format.
