Hi,

I will assume you are using mingw to build ffmpeg.

First of all you need the Windows version of libdl, found here:

http://code.google.com/p/dlfcn-win32/

After installing it, you should configure ffmpeg with '--enable-vhook 
--disable-static --enable-shared' and rebuild it.

FFmpeg will then be built with the watermark dll.

Hope that helps.
