Hey!
Just take a look at the mpv PKGBUILD (https://gitea.artixlinux.org/packages/mpv/src/branch/master/PKGBUILD)
optdepends=('yt-dlp: for video-sharing websites playback'
'youtube-dl: for video-sharing websites playback')
youtube-dl is dead and should be removed.
It isn't dead. Though arguably maybe should be ?
You might be confusing youtube-dl with youtube-dlc ?
youtube-dl is maintained by ytdl-org (https://github.com/ytdl-org/youtube-dl)
And the same, or very similar, functionality is in
yt-dlp maintained by yt-dlp (https://github.com/yt-dlp/yt-dlp)
Maybe they fell out ?
Well, maybe it isn't dead but youtube-dl is not in the official artix/arch repositories. It's in the AUR.
EDIT: The term "useless" was perhaps not the most
appropriate for the title of this topic, I admit. ;)
