Have you read a similar recent discussion on stackoverflow(
http://stackoverflow.com/questions/11701635/use-ffmpeg-in-visual-studio)?

Today zeranoe archives include version number in the dll names. Are you
using a different source of precompiled Windows binaries?

Anyway, it's good practise to install the DLLs in your app directory, next
to the executable that will load them, and not in a shared directory where
other applications could override them or be hit because your installation
overwrought the files they relied upon.

BR,
Alex
