No. FFMpeg does not support plugins.
Installing 'xpra' will only install the Fedora package. Fedora packages cannot
require an external package such as from RPMFusion (xpra-codecs-freeworld). You
installed this yourself.

Correct. It is possible to ship packages in RPMFusion that could either replace or
extend software that requires patent encumbered software. The
'xpra-codecs-freeworld' package allows linking with ffmpeg and extending xpra
support. Anyone could correct Fedora packaging to match upstream's (Antoine's)
standards. Fedora is not a closed ecosystem. Many upstream maintainers publish their
own packages directly in Fedora.
