If you configure ffmpeg with --enabled-shared, the ffmpeg binaries
will be dynamically linked to it's libraries (libavfilter, libavcodec,
libavformat etc).

The libraries should be installed somewhere appropriate for your rtld
to find. "make install" would do this, I've no idea what checkinstall

If you have no need to dynamically link to these libraries, don't.
