Unable to load a shared library ‘libavformat.so.59’ or one of it’s dependencies.

I've downloaded the code and compiled it. I then reference the two assemblies in the bin directory.

I'm running on Raspberry Pi. When I try to load the video file I get this error:

System.DllNotFoundException: Unable to load shared library 'libavformat.so.59' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: liblibavformat.so.59: cannot open shared object file: No such file or directory

On the pi I run the ffmpeg -version and get the following:

ffmpeg -version

It says it can't find libavcodec.o.59, but if I'm reading that correctly shouldn't it be libavcodec.o.58?
