Sorry in advance if this question is too specific to Unreal Engine, but after 6 months of working, this is the last piece that I need to complete, and I have become desperate.

After creating an Unreal Engine C++ base project, added some .h and .cpp files with VS class wizard, I can't use functions like AVIFileInit and other similar ones, even though I have included Vfw.h and put it inside AllowWindowsPlatformTypes.h and HideWindowsPlatformTypes.h. All I get is error LNK2019: unresolved external symbol AVIFileInit referenced. What I want to do is experiment in Unreal Engine based on the article Various methods for capturing the screen.

I have tried to put all the code into a separate VS project and building it as a static library, and then linking it to the Unreal Engine project. All is fine, but when I try to build the project, it generates a list of LNK2001 errors, all of which involve functions like AVIFileInit, AVIFileExit, ...

Note: I am using version 4.6.1

Any help and tip would be much appreciated.

You should add Vfw32.lib to your project from Project Properties -> Linker -> Input -> Additional Dependencies.
