Please delete orphaned package https://aur.archlinux.org/packages/vlc-spros-plugin/
It is a duplicate of https://aur.archlinux.org/packages/vlc-rpos-plugin/ and https://aur.archlinux.org/packages/vlc-srpos-plugin/ which should be merged to vlc-srpos-plugin/ - the name of the code project I think this one can also be deleted - it is unmaintained, outdated and skins2 is now included in extra/vlc https://aur.archlinux.org/packages/vlc-skins2/
