Hey Jonathan, I'm doubtful to be the best person to answer, but in general you would be fine with using your distributions version of ffmpeg. This is not true with other components in the third party tools, but we invoke ffmpeg via command line so any modern packaged version for your distro is probably fine.
The subscript being that it depends on what you are encoding to, but if you are just interested in ingest mpeg2 (capture agents) and encoding to on2 flv (engage side for 1.0) then you should be fine with a distro version.
