### PC Video Device Driver Sample

Driver Description:

The PC Video Device Driver is an Overlay and Video Capture device driver. It uses the popular PC Video Pro Chip (69003/69004) from Chips and Technologies, Inc. Parts of this device driver were ported from the PC Video Developers Kit from Chips and Technologies, Inc.

The PC Video Pro Chip is used in many popular overlay cards such as Video Blaster, Super VideoWindows, Win/TV from Hauppauge Computer Works, and others.

Writing a Video Capture device driver to this interface will allow your capture card to plug into the MCI (Media Control Interface) of OS/2 and all applications written to the MCI supplied in the IBM Ultimedia Video IN product.

VIDVBC1.INI contains the default configuration information for the Video Capture card. This file is read by the VSD and passed to the device driver on an IOCTL (Device Specific Setup Information) after the device is opened. The name of this file must match the name of the device driver. For more information, refer to the PC Video section of the MMPM/2 Device Driver Reference in the DDK\DOCS directory on the CD-ROM.

Compilers/Assemblers Required:

         Microsoft MASM 5.1      (supplied with the DDK)

Build Instructions:

1.Set the environment variables so the correct tools are picked up during the build.

    e.g., SET PATH=<drive>:\DDK\TOOLS;%PATH%

Where <drive> represents your DDK installed drive and DDK represents the DDK installed directory. On the CD-ROM, the TOOLS directory path is DDK\ TOOLS.

2.Change the directory to DDK\BASE\SRC\DEV\MME\VBLASTER.

3.Invoke NMAKE on the resident makefile.

Files Created By Successful Build:

         Directory:  \DDK\BASE\SRC\DEV\MME\VBLASTER
