For the sake of completeness, this is not 100% accurate: ffmpeg can be
built under the GPL license and without the nonfree codecs.
xpra's ffmpeg encoder which we are discussing in this thread can be
enabled without those.
Whether that's practical or not is another question.
You're being extremely pedantic. Let's back up.
Sure, it can. Will anyone package and ship it in Fedora that way? No.
Besides the enormous effort to strip out the patented code the handful
of codecs that would remain wouldn't make it useful. Disabling the
codecs at build time is not enough if we want to be pedantic.
There's a lot more to this than just the patented codec issue:

I think you missed my point. I was not saying "package the Fedora
version into RPMFusion" -- I was saying take your (xpra.org) packages
and ship them in RPMFusion.

As a slight aside to this. My "dnf install xpra" from the Fedora33
repositories + rpmfusion + fedora-cisco-openh264 repositories does in
fact have h264 and h265 support. So I presume the Fedora33 standard
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.
Actually I see that the Fedora33 xpra is using xpra-codecs-freeworld
from rpmfusion.
I presume with those hardware codecs the license is with the hardware ?
