There are a number of screen recording alternatives that are simpler

license that is compatible with the main Fedora repository
(https://ffmpeg.org/legal.html), but is typically built with a
number of nonfree dependencies
https://github.com/rpmfusion/ffmpeg/blob/master/ffmpeg.spec - CUDA
support, libfaac, libnpp, libfdk-aac One could compile a version of
FFMPEG without these, but performance on some platforms may drop
significantly and some functionality may be missing. Not clear if
this would be useful for other projects that depend on FFMPEG as well.
Licenses are not the only issue.
The big issue with ffmpeg, like with many multimedia related
things, is patents.
Thanks for the clarification. FFMPEG seems not to have very many
alternative software packages. Royalty free codecs are also being
developed, for example AV1 (https://en.wikipedia.org/wiki/AV1), and
adoption of these will likely grow. I suspect there would be interest
in having a royalty free version of FFMPEG for use by content creators
that satisfies Fedora packaging guidlines, though unclear if at
present this would be useful for many of the multimedia related
packages. This would also likely need some interaction with FFMPEG
developers.
Relevant packaging guideline:
