在DirectShow Project中获取未知错误 [英] Getting Unknown errors in DirectShow Project

问题描述

我从链接 GMFBridge-DirectShow中的多图

我添加了以下库

C：\Program Files\Microsoft SDKs \Windows\v7.1\样本\多媒体\directshow\基类\Debug\strmbasd.lib

C:\Program Files\Microsoft SDKs\Windows\v7.1\Samples\multimedia\directshow\baseclasses\Debug\strmbasd.lib

C：\Program Files＼ ＼Microsoft SDKs\Windows\v7.1\Lib\winmm.lib

C:\Program Files\Microsoft SDKs\Windows\v7.1\Lib\winmm.lib

C：\ProgramFiles（x86）\Microsoft Visual Studio 10.0\ VC\lib\comsuppw.lib

C:\ProgramFiles (x86)\Microsoft Visual Studio 10.0\VC\lib\comsuppw.lib

在构建项目时出现错误：-

推荐答案

1. 项目本身和 strmbasd 库需要使用相同的项目设置来构建，以很好地链接
   
   
   
   • 有关编译/链接的一般建议，请参见三月野兔常见问题解答
   
   
   • S earch MSDN DirectShow论坛涉及许多主题
   
   

1. The project itself and strmbasd library need to be built with the same project settings to link well
   • See general advice on compiling/linking at The March Hare FAQ
   • Search MSDN DirectShow Forum with dozens of topics on compiling and linking DirectShow projects
