摘要:
论述采用DirectShow技术进行实时视频信息的采集和压缩存储的方法,并给出详细的设计思路。设计中视频捕捉采用WDM驱动捕捉,提高视频捕捉的效率和通用性;采用基于内容的MPEG-4视频编码标准进行压缩,得到较高的压缩比和压缩质量。该技术已经成功地应用到笔者参与开发的视频会议系统中,有效提高了采集速度和视频质量
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
