I need to develop a rest API for publish and convert the videos

A major what I am facing, I need a free converter for convert any format video in OGV. Even though ffmpeg is the best candidate, but we I cannot use it because not is in official Fedora repository, just is in rpmfusion. I am developing a product that would be deployed on Fedora infra, they only deploy applications via packages into epel6.

Can you guys suggest something from official fedora repository ?
