:: installing libplacebo (1.29.1-1) breaks dependency 'libplacebo.so=21-64' required by mpv
Both [community/mpv] and [extra/libplacebo] come directly from Arch. We do not adjust or package them.
Looks like our repos are currently behind on mpv.
I'd suggest wait a bit for the next repo sync and see if that fixes it.
If this isn't fixed by the morning I'll see is winston needs a poke.
