[Ffmpeg-devel] Build ffmpeg on Win32

[Steve Lhomme]

I just tried it and it works fine for me (apart from that configure 
error which is a bad understanding of the Windows API that provides some 
memory alignement features, even provided in MinGW)

There's probably something wrong with your MinGW+Msys installation. An 
option could be an environment variable set that will make it look in 
the wrong include directories. Otherwise I suggest trying on another 
(fresh) machine or reinstalling it on yours.
