MarsSeed [1] filed a deletion request for gstreamer-properties [2]: Defunct GNOME3 applet from 2012 for gstreamer0.10 graphical configuration.
Its gstreamer0.10 dependencies on AUR have been unmaintained for years, and are now broken, unbuildable. It doesn't seem worth keeping this unused PKGBUILD. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/gstreamer-properties/
