Hi,
Today I realized that ffmpeg-compat is not required by any package [1],
perhaps we may drop it (I still in review some packages that are lost
on migration for new infra (like subtitleripper)) .
Orion Poplawski, I'd like have an agreement on how put ffmpeg in epel7.
What you say ? may we have one ffmpeg ? , should we have multi ffmpegs
? etc.
Thanks.

The 8 years argument is good but one point is need keep it simple.
From
what I see, end use shouldn't have choices, we build applications
against the main ffpmeg , we already have ffmpeg-compat, if in 4
years
we need update ffmpeg, we update the main ffmpeg , if something still
need old ffmpeg we can make one second ffmpeg-compat-2.8 or ffmpeg-3
(if want innovate) but when we need that ? in 4 years, now we need
just
one main ffmpeg .
Don't like the idea have the possibility of install lots of versions
of
ffmpeg , end user just need one and shouldn't worry about what
version
is, your solution is more complicated, may give much more work and I
don't see great benefits.
