摘　　要：针对基于H.323协议的Openh323开源视频会议系统中所采用的VFW视频捕捉时延长,与目前的视频采集硬件兼容性较差等缺陷,在VC6.0开发平台上将基于DirectX的DirectShow应用到系统的视频捕捉当中,以减少视频捕捉时延,使视频图像更加流畅,并取得了较好的效果。The paper deals with the problem that video capture delaying and less poor in Hardware comp - atibility of VFW in Openh323 open source video confereneing system which basing on H323 protocol, in order to reduce the delay to make video images more fluent, it is available to adopt DirectShow based on DircctX to apply into this system by use of VC6.0 platform. And getting batter results.
