As a slight aside to this. My "dnf install xpra" from the Fedora33

ffmpeg is being extended to support h264 by "plugin" h264 packages
from those external repos. I'm not sure it supports hardware vaapi
h264/h265 though.
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.
Actually I see that the Fedora33 xpra is using xpra-codecs-freeworld
from rpmfusion.
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.
I presume with those hardware codecs the license is with the hardware ?
No.
Are you sure that hardware based H264/HEVC encoder/decoder usage license
is not covered by the manufacturer/supplier of the hardware codecs ?
