Is this using the gnome-software tool or after you've
installed the package and somewhere in firefox?

If the former, then that's likely because the f28
fedora-cisco-openh264 repositories are not populated yet.
(I installed the f27 packages by replacing $releasever in
the fedora-cisco-openh264 repo config with 27 to test.)

If it's the latter, then I'm curious where that occurs.

Indeed, that matches what Sam and I found as well.  Now that
compat-ffmpeg28 is in the rpmfusion-free repo for f28, it's
easier to install than when it was only in the
rpmfusion-free rawhide repo (it was built before f28
branched).

At this point it's just a mild curiosity whether the Cisco
OpenH264 plugin works with youtube.  I think we'll have to
wait for the proper f28 builds to test that further, but I'm
not betting they will).
