Kind of silly though to allow user to update the ffmpeg libraries. Every time I get new ffmpeg libraries I test it for quite a long 
time and not unusual to find something broken or something has changed that leads a break somewhere else. Don't know about you but 
things need to work for me and if user is just adhoc changing the libraries then that's a problem.
