If you are providing a driver for a webcam or a digital camcorder, consider using the system-supplied universal serial bus (usb) Video Class mokhanni, Usbvideo.sys. The USB Video Class (UVC) driver is a Microsoft-provided AVStream minidriver that provides driver support for USB Video Class devices. When your device uses UVC, you do not need to supply your own driver. Ho ena le hoo, the device works automatically with the system-supplied driver.

In the USB Video Class model, vendors do not write drivers; instead, vendors implement video streaming hardware according to the guidelines in the Universal Serial Bus Device Class Definition for Video Devices Specification. The UVC driver queries the hardware directly to obtain its capabilities and then drives the device, with no proprietary driver required.

You can optionally extend UVC driver functionality to add vendor-specific processing.

Beginning with Windows 8, the H.264 video codec (encoder/decoder) is supported. H.264 is an open standard that allows efficient video compression techniques for reducing the use of network bandwith and storage space. This leads to a higher video quality for a given bit rate. For more information, see USB H.264 Video Cameras Support. Also refer to theMicrosoft Proposed Extensions to the USB Video Class for H.264.

The following list shows some advantages to using the Usbvideo.sys driver:

  • No CD required for installation
  • No driver writing cost
  • No maintenance cost
  • Opportunity for vendors to add functionality
  • Easier debugging with public symbols
  • Works with Driver Verifier
