Lets try and keep this topic on the topic of linking the static 
libopenjp2.a and away from religious dogma please.

Correct me if I'm mistaken, but AFAIK, ffmpeg does not maintain an 
srpm?. In any event, that would be tricky to do for static builds, given 
the licensing. So that leaves us with guides like this one 
https://trac.ffmpeg.org/wiki/CompilationGuide/Centos .

Your constructive feedback is appreciated.
