Obtaining file lists from packages is trivial, just bsdtar tf all
packages... and we should do this anyway to have $repo.file.tar.gz
databases. But IIRC those aren't easily parsable (too many files).
You can also temporarily extract files under binary directories and make
a database of linked libraries, then compare. When something's missing,
a binary just broke.
mplayer-libre links to x264:
$ ldd mplayer
^ store that
Look for /usr/lib/libx264.so.8 on file database. If missing, mplayer is
broken. This can be done in a relational database fashion to have
immediate results instead of individual checking.
There's an Arch script that checks repositories health. Maybe it does
this already? It's on dbscripts.git, if you're subscribe to
arch-dev-public you'll see the reports.
