Sergio:

Thanks.  It turned out that I had a conflicting file from the Community Squeeze site, which I use for the community version of the Logitech Media Server -- the old Squeezebox Server -- for my networked music players.  The file was their ffmpeg2-libs rpm (the file is here: http://www.communitysqueeze.org/repo/19/x86_64/ffmpeg2-libs-2.0.1-1.fc19.x86_64.rpm), but I was only using it for the Squeezelite player.  The Community Squeeze site states that it depends on RPMFusion for dependencies, so I'm not entirely sure why there is a conflict.  I've been trying to find a place to file a bug with the Community Squeeze people, but so far have had no luck.

FYI, their squeezelite package depended on the ffmeg2-libs file, but if I compiled it from source, it wasn't needed, so I removed the package and compiled from source.

hum it is working here.
It works simple like this:
python
from openshot.openshot import main
main()

but goggling it is a common problem for example :

Please do: ldconfig as root , before try start openshot .
Thanks,
