MarsSeed [1] filed a deletion request for qtav-git [2]: EOL since 2022. [a] Broken, as reported in AUR comment in 2023. Also upstream no longer takes care of issues, as per automated answer: NOTE: QtAV is no longer maintained, please use new sdk Enough to keep AUR/qtav, which was building fine (with legacy ffmpeg4.4) the last time I checked.
