Answer 1

You need to do following all tasks to use libav with MSVC++. First goto Zeranoe

1. Download Shared Version, Copy all .dll files from bin folder and paste them in the output directory where exe will be generated.
2. Download Developer Version, Copy all .lib files from lib folder and paste them with your main c++ file is located (e.g. Folder-1\Folder-2 Where Folder-1 has the .sln file so you have to put .lib files in Folder-2)
3. From Developer Version you downloaded in Step 2 copy all directories from include folder and paste them in Folder-2 (See details about Folder-2 in step 2)
4. Download inttypes.h and stdint.h, save it on this location C:\Program Files\Microsoft Visual Studio 10.0\VC\include\ folder.
5. To include header files use following syntax

You have to use this extern because libav is a C library.

extern "C" {
    #include "libavcodec/avcodec.h"
    #include "libavdevice/avdevice.h"
    #include "libavfilter/avfilter.h"
    #include "libavformat/avformat.h"
    #include "libavutil/avutil.h"
}

Answer 2

What about compiling it as a .lib static library?

Answer 3

Fetch the 32-bit libraries and you should be fine :) Your application platform has to match the libraries used (and vica versa).
