With Gentoo that is usually the most expedient solution, cost of time
considering.

I've been periodically fighting with mpv and ffmpeg for various reasons
for quite some time.  Which is why I've been pushed into running live
versions of both.  Version bumps on ebuilds that fail version checks
(like this one) is my first line of defence.

The reason live rebuilds keep breaking even though they're installed it
the upstream developers change to library requirements and flags without
telling anyone.

There's a bug report about this at https://bugs.gentoo.org/635650 which
seems to offer several solutions and satisfies none...  It looks like
the decision at present is "wait and hope it gets fixed upstream"

I installed ffmpeg- and it compiles fines.

Everything else failed again (for example mpv-).

Why does an update of already ok installed applications
break something in parts because the installation
has components, which are mutually exclusive?
They weren't before (whichout the update everythong was fine...)

I've got mpv- installed.  I'm pretty sure you need to move to
ffmpeg- as well.

Also, libav and ffmpeg are mutually exclusive.  You can have one, but
not the other.
