You should only need ffmpeg-libs in Firefox 60, not
compat-ffmpeg28.  The compat package was a temporary fix for
the lack of ffmpeg-4.0 support in Firefox < 60.  (In
upstream Firefox it's < 61, but the Fedora firefox-60
packages include the (large) ffmpeg-4.0 patch.)

The Cisco OpenH264 packages definitely aren't sufficient for
general-purpose H.264 decoding.  The wiki does say this, but
there is apparently some confusion about it still.

AFAIK, the wiki is correct.  The Cisco OpenH264 packages
only provide WebRTC, which is great if you need it.  But
it's not what most people want when they search for H264
codec support.

If there is documentation stating that the Cisco OpenH264
packages provide general H264 decoding, it should be
corrected.   (If someone with authority says it should work,
then there are bugs to be filed and fixed.)
