MarsSeed [1] filed a deletion request for ilbc [2]: Abandoned old codec implementation from 2016.
Conflicts with extra repo's libilbc, which comes from a newer implementation (Google WebRTC project). Nothing depends on it. Better to delete. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/ilbc/
