Landing here, yes for me make sense f23 version (ffmpeg-2.8.7-1.fc23 )
is well tested

I'm not seeing how we could install 2 versions of ffmpeg (I not read
all thread) but IMO ffmpeg-2.8.7 should be the main package . 

I peeked to Orion ffmpeg specs and I think main ffmpeg shouldn't have
versionsuffix , neither alternatives would work here ... 

Conclusion, IMHO ffmpeg-2.8.7 should be the main package and we could
build it right now and maybe later also ship one (just one) more
version of ffmpeg (3.1.2) , with versionsuffix if not conflicts, I
think will not have conflicts, but not as alternative
(/etc/alternatives)
