MarsSeed [1] filed a deletion request for lib32-libmp4v2 [2]: I suggest this old lib32 library can be deleted. This is currently at v2.0.0 whereas its 64-bit counterpart in Arch/extra is at v5.0.1. There have been no user comments since 2017. Nothing on AUR depend on this. MPEG4 file tags can be modified with native-built tools, no need for this 32-on-64-bit library. Therefore it's safe to delete; no impact. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/lib32-libmp4v2/
