MarsSeed [1] filed a deletion request for gstreamer0.10-gnonlin [2]: Unused, abandoned gstreamer0.10 plugin from 2018. Its gstreamer0.10-base dependency is broken and unmaintained since years.
Better to delete this superfluous and defunct pkg. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/gstreamer0.10-gnonlin/
