[FFmpeg-devel] (MSVC++) warning LNK4248: unresolved typeref token (01000015) for 'AVDictionary'; image may not run

[John Dexter]

I've just got ffmpeg working through MSVC++ 2008 using prebuilt libs,
everything seems to be working in my test project but I get this one
linker error and have no idea if it's a problem.

Is this normal, should I worry, etc?
