It seems that you have compiled the library with MSVC. FFMPEG can't be 
compiled by default with MSVC. You might have to look for DrFFMPEG for 
that. Otherwise try to use MinGW & MSys. You'll have to do "make 
install" for faac before configuring FFMPEG.

PS: I've never tried it, but I assume it's the same as for LAME.
