youtube-dl

youtube-dl is a command-line program and Python library designed to download videos from YouTube.com and many other video-hosting sites. The official PyPI package, version `2021.12.17`, is no longer actively maintained and is significantly outdated. For current site compatibility, bug fixes, and new features, users are strongly recommended to use the `yt-dlp` fork or the `youtube-dl` nightly builds, which are built from the main repository's `master` branch.
