Development screen capture Mirror driver

Mirror driver mirroring Drive, directly create a virtual graphics driver (personally think), the application calls the operating system needs to change the graphics display in advance intercept the application needs to display the area and content, and buffer into memory. Comparing the methods that capture the screen in real time and compare differences has the following advantages:
1, CPU occupancy rate is small, generally under 5%, real-time high
2, do not need to compare differences, because the interception is the difference part of the image buffer
Required driver files:
Mirror.dll, Mirror.inf, Mirror.sys
How to obtain these files:
1. Download Win2K DDK from Microsoft website
2, installation DDK, such as F:/W2KDDK
3, compile f:/w2kddk/src/video/displays/mirror/dll/under Mirror.dll, compile method: After installing DDK in the Start menu-Development kits–windows Run free build environment into DOS mode, enter the above directory, enter build SZ
4, compile F:/w2kddk/src/video/miniport/mirror Mirror.sys
5, copy or modify F:/w2kddk/src/video/displays/mirror/app/mirror.inf files, driver files
