C + + configuration FFmpeg

This tutorial is only configured for windows64/32+vs2013 environments
First step: With Environment
1. Open the compiled Windows version in FFmpeg official website http://ffmpeg.zeranoe.com/builds/
64-bit Windows systems and 32-bit systems each have three versions of the static version, share version, dev version;
It is recommended here that both 32-bit and 64-bit systems are directly configured with a 32-bit FFmpeg version, unless you vs2013 select the x64 compiler.

Download and unzip the 32-bit version share version and Dev.
In Dev the main is some header files and Lib, in the share version of the main DLL files.

2. Open vs2013 and create a new Win32 console program.
Select the project-"Properties-" C + + directory to open the include and Lib in the dev version in the included Directory and library directory (referring to the location where you unzipped dev save, where include and Lib are found)

3 Item-"Properties-" linker-"input-" the dependency is filled in

Avcodec.lib
Avformat.lib
Avutil.lib
Avdevice.lib
Avfilter.lib
Postproc.lib
Swresample.lib
Swscale.lib
Save it.

The second step: Video decoding, here is a complete video decoding project, from decoding to storage, can be run on vs2013, if the compilation is unsuccessful, you can consider whether the environment is wrong.
