Readme file for ASUS WDM Video Capture MiniDriver
==================================================
Description:
------------
Asuswcap is a WDM stream class video capture minidriver which supports the SAA7113 video
digitizer chips from Philips. It manifests itself in a DShow graph as two filters, "ASUS WDM
Video Capture Driver", and "ASUSWCAP Crossbar".
This is a fairly complex driver, in that it supports an input stream representing analog
video, a capture stream for video data, and an output connection point for DDraw surface
allocation filters (Overlay Mixer). It also supports input selection via "ASUSWCAP Crossbar".
The actual capture operation is implemented by an interface to Kernel DirectDraw.
Capture buffers are passed to KDDraw, where they are filled by a bus master operation.
