Changes are, you cannot and you should not. First of all, you need to understand what ".so" means. This is "shared object", executable file, same thing called "DLL" in Microsoft domain. The file has the executable file format of the particular OS and presents the code of some library already compiled to the target
instruction set of a target CPU. Most executable file formats are shared between many OS, but there are differences. You can only use this .so if someone has built it targeting your exact system. I'm not sure if this is the case or not.
On the use of shared objects, please see:

To use FFMPeg in your program (I am not mentioning apparent possibility of spawning just a utility in a separate process; if you are asking about ), you need at some C/C++ programming. Please see:

You could consider this compiler and IDE:

And then, you can use the source code of FFMPeg or libavcodec (which FFMpeg includes):

http://en.wikipedia.org/wiki/Libavcodec[

Good luck,
