Hi i have the following probem: i adquired a ffencoder.dll wich can make .mp4 videos. I had to compile it in Ubuntu, following the author howto. The thing is that he says that a .lib for the .dll can be made with visual studio tools. I followed a guide to make the .lib. First i wrote a .def files with the "EXPORT" functions with the fuction that i wanted to export. Then used msvc lib tool to make the library. I made the lib successfully. But doesn't work, visual c++ still says "cannot resolve simbol xxxx". I made all the steps well, i don't know what else i can do.
