从各种视频设备捕获实时视频 [英] Capture Live Video from various Video Devices

问题描述

朋友，我是VC ++的新手，我从各种视频设备上阅读了名为Capture Live Video的文章.我下载了文章的源代码，并在编译后显示致命错误C1083之类的三个错误:无法打开包含文件:``dshow.h'':没有这样的文件或目录，所以我安装了Microsoft Platform SDK，并通过工具->选项->目录选项卡包含了目录，并且在编译源代码后出现了48个错误... .

推荐答案

我认为所有这些错误都将出现，因为程序无法包含dshow.h.检查安装. :)

I think all those errors are coming because the program cant include dshow.h. Check the installation. :)
