ffmpeg requirement might a blocker for Fedora repository unless
someone
it can be built without ffmpeg
https://bugzilla.redhat.com/show_bug.cgi?id=428568
but the problem that it kept crashing on my PC
some one gave me an rpm with all deps library included in it, that one
did not crash.
I wonder what was the problem, I'm still puzzled
maybe I would retry it in F11
