youtube-dl --external-downloader=aria2c --external-downloader-args '--min-split-size=1M --max-connection-per-server=16 --max-concurrent-downloads=16 --split=16' xlvbT8dv5Gc
[1] https://aria2.github.io/yt-dlp uses a different method than youtube-dl (I believe it uses the API used by the Android app, instead of by the youtube.com website).
Clever.
Since mpv 0.34 it even looks for yt-dlp first, and fallback to youtube-dl otherwise. Before that you had to set an option, or just symlink youtube-dl to yt-dlp.
What option?
Symlinking either into ~/.config/mpv/ (or wherever your mpv config is) should also work.
On one hand I'm sad to see youtube-dl's demise. But its prompt replacement gives me hope for the strength of the community to overcome whatever challenges the IP industry might present.
