<P>

The AVSHwS sample provides a pin-centric AVStream capture driver for a simulated piece of hardware.
 



The driver performs captures at 320x240 in either an RGB24 or YUV422 format via direct DMA into capture 
buffers.  The purpose of the sample is to demonstrate how to write a pin-centric AVStream minidriver.
The sample also shows how to implement DMA by using the related functionality
provided by AVStream.

<H3>BUILDING THE SAMPLE</H3></FONT><FONT face=Verdana size=2>
<P>

Build the sample by typing <B>build -zc</B> in either the standard checked or free build
environment. A successful build produces <i>avshws.sys.</i> 
To install the driver, right click on <i>avshws.inf</i> and select Install.
When prompted for <i>avshws.sys</i>, select the built binary.<p>



The sample works on x86 platforms and builds 
correctly using Microsoft&#174; Visual C&#174; 6.0. The driver uses Plug and Play.

This sample runs on Microsoft
