Method of Video Captures and Encoding Based on DirectShow Technology

An implementation of the video captures and encoding based on DirectShow technology is put forward in the paper. It adopts WDM ( Windows driver model) as the video capture method, which can enhance the efficiency and generality of the video capture. It utilizes MPEG-4, one of the video coding standards based on content, to encode the video stream, which can result in higher encoding rate and better encoding quality. This paper introduces the architecture of DirectShow technology, and shows the procedure of realization of the video captures and encoding based on DirectShow.
