Maximum Control and Flexibility
Command-line tools (CLI) offer the most power and flexibility for downloading streams. Used in a terminal or command prompt, these tools provide granular control over every aspect of the download process. They are ideal for technical users, developers, and anyone who wants to automate their downloads.
Why Use Command-Line Tools
CLI tools have several advantages. They are lightweight and run on any system with minimal resources. They can be scripted and automated. They offer the most options for quality, format, and post-processing. And they are often free and open-source.
The Gold Standard: yt-dlp
yt-dlp is the most powerful and versatile command-line tool for downloading streams and videos. It is a fork of youtube-dl and supports hundreds of websites. It can handle live streams, playlists, and individual videos. It offers a huge range of options for quality, format, and post-processing.
Basic usage is simple: yt-dlp [URL]. Advanced users can specify resolution, codec, format, and output location. yt-dlp can also extract subtitles, metadata, and thumbnails. It supports cookies for logged-in content and can resume interrupted downloads.
livestream_dl
livestream_dl is a robust YouTube livestream downloader built on top of yt-dlp. It focuses on reliability, featuring stream recovery if a broadcast goes private and dual write modes for unstable connections. It also supports downloading live chat, making it ideal for archiving entire broadcasts.
Streamlink
Streamlink is a Python-based command-line application designed specifically for extracting streams from various services. It reliably handles live HLS streams and is the engine behind Stream Downloader for Twitch. You can use it to both watch and download live broadcasts.

Learning Curve
