[vtkusers] FFmpeg writer compiling on OSX

[Gerrick Bivins]

I ran into some errors when trying to compile the FFmpeg writer with VTK on
OSX. I installed ffmpeg with macports but VTK failed to compile with the
following errors:

Does anyone have any suggestions?Do I need to manually compile/install
ffmpeg myself?
