Currently you need vapoursynth -> ffmpeg-git -> mpv-git.
That's all thankfully rendered unnecessary in the near future because https://gitlab.archlinux.org/archlinux/packaging/packages/mpv/-/merge_requests/1 was finally merged, it's just waiting for https://gitlab.archlinux.org/archlinux/packaging/packages/vlc/-/merge_requests/1 and a subsequent mpv package update.
