MarsSeed [1] filed a deletion request for lib32-libmms [2]: Unneeded lib32 package for a deprecated streaming protocol.
GStreamer dropped support a year ago, with v1.20.0 release. Safe to delete, no package depends on it. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/lib32-libmms/
