MarsSeed [1] filed a deletion request for gst-plugin-libde265 [2]: Orphaned, last updated in 2015. Unneeded because it has been upstreamed to gstreamer repo and is included in gst-plugins-bad: 9-year old version (this package): https://github.com/strukturag/gstreamer-libde265/tree/master/src Current version (in gstreamer monorepo): https://gitlab.freedesktop.org/gstreamer/gstreamer/-/tree/main/subprojects/g... plugins-bad/ext/libde265 Arch [extra] gst-plugins-bad depends on libde265. GStreamer source directly supports it. So this package is unneeded. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/gst-plugin-libde265/
