基于DirectShow视频帧实时捕捉的设计与实现
主要针对远程教育等软件系统中现存的 黑屏 问题提出一种解决方案。运用D irectShow 技术对多媒体文件或多媒体流
中的视频流进行处理, 实现从多媒体文件视频流中进行视频帧的实时捕获, 而后调用W indow s中GDI函数对获取的图像帧进行渲
染, 最后按照M PEG2标准合成AVI视频文件并可以实时重放。-In this pape r, w e present a so lution to reso lve the .. black screen problem occurred in softw are sy stem such as distance
