Abstract

Describes a method of using DirectShow to implement the video captures and compression,and explains it with particular designing thoughts.It adopts WDM as the video capture method,which can enhance the efficiency and generality of the video capture.It utilized MPEG-4,one of video coding standard based on content,to encode the video stream,which can result in higher encoding rate and better encoding quality.This technology has been used at Video Conference System,improving the speed and quality for capture greatly.
