Compiling FFMpeg in Windows MSVC

Open a common prompt (not the power shell) and run the MSVC shell:
	32 bits - "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat x86"
	64 bits - "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat x86_amd64"

------------------------------------------------

Compiling 64 bits

Compiling libx264: 

First install "nasm" and put the exe path in the system PATH

CC=cl ./configure --enable-static --prefix=. --extra-cflags="-DNO_PREFIX"
