FabioLolix [1] filed a deletion request for ffmpeg-ubuntu-bionic [2]: This pkgbuild never delivered what promised; pkgver is set to 4.1 but is not used; instead v3.4.4 (which is no longer available) is downloaded. Ubuntu patches are not even downloaded. [1] https://aur.archlinux.org/account/FabioLolix/ [2] https://aur.archlinux.org/pkgbase/ffmpeg-ubuntu-bionic/
