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 ?
