利用VC++实现基于DirectShow的视频捕获

Using VC++to realize video capture based on DirectShow

基于COM技术的DirectShow给出的视频处理模型克服了传统的VFW(VideoForWindows)编程模式的许多不足之处,利用VC++实现了一种基于DirectShow的视频捕获的方法,实验证明,捕获速度和质量都得到了大幅度的提高。

DirectShow is based on COM structure.It has overcome VFW's shortcomings in processing video.In this paper,VC++is used to realize a method for video capture.According to the author's practice,it has improved the speed and quali-ty for capture greatly.
