Instead, DirectShow provides automatic support for audio and video capture devices, using wrapper filters and the System Device Enumerator. For more information about implementing a device driver, refer to the Windows Driver Development Kit (DDK) documentation.

This section is intended only for developers who need to capture some kind of custom data from an unusual hardware device.
