      yt-dlp is a youtube-dl fork based on the now inactive youtube-dlc.

      youtube-dl is a small, Python-based command-line program
      to download videos from YouTube.com and a few more sites.
      youtube-dl is released to the public domain, which means
      you can modify it, redistribute it or use it however you like.
