Using FFMPEG in a Visual Studio 2013 ultimate project, linking error LNK2019

Question

I'm trying to use FFmpeg library and TIFF lib in my project (I'm making a .dll and/or .exe also). I have searched through the answers provided in here and Google, and linked the /dev/include 64-bit (32-bit VS making 64-bit project) to Additional Include Directories and shared/bin (library files) 64-bit to linker->Additional Library Directories and did the Linker->Additional Depedencies->avformat.lib addition. I also copied the .dll files to my project folder, but I still keep getting the LNK2019. Here's how I use the libs and the output of the compiler:

extern "C" {

#ifndef inline
#define inline __inline
#endif
#ifndef UINT64_C
#define UINT64_C uint64_t
#define INT64_C int64_t
#endif

#include <libavcodec\avcodec.h>
#include <libavformat\avformat.h>
#include <libswscale\swscale.h>

}
#pragma comment(lib, "avformat.lib")

Answer 1

You have to link other FFmpeg libraries as well (avcodec, avutil, etc). Same for libtiff.
