If you have specific use cases (audio-only, playlists, private videos, etc.), I can show those too.\n\n---\n\n## What Is yt-dlp?\n\n- yt-dlp is a command-line tool (written in Python) used to download videos and/or audio from YouTube and many other sites. It\u2019s a community-driven fork of youtube-dl, adding more features, faster updates, and better format selection. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Youtube-dl?utm_source=openai))  \n- It supports extraction of metadata (titles, descriptions), subtitles, chapters, thumbnails, etc. ([git.seabaer-net.eu](https://git.seabaer-net.eu/gitea/Seabaer-Software/MyLinuxBook/raw/branch/main/LinuxBook.pdf?utm_source=openai))  \n\n---\n\n## How It Works\u2014Under the Hood\n\n1. **URL & Extractor**  \n   - You give `yt-dlp` a URL.  \n   - The tool uses \u201cextractors\u201d \u2014 site-specific modules/scripts \u2014 to interpret the URL and figure out where and how to download the video (or video + audio) streams. For YouTube, yt-dlp has extractors based on different client types (`web`, `mobile web`, `tv`, etc.) and may require special tokens or cookies depending on restrictions. ([github.com](https://github.com/yt-dlp/yt-dlp/wiki/Extractors?utm_source=openai))\n\n2. **Get Available Formats**  \n   - It will list or examine available formats (video-only, audio-only, their qualities / codecs). You can ask it explicitly with `-F`. ([yt-dlp-yt-dlp.mintlify.app](https://yt-dlp-yt-dlp.mintlify.app/quickstart?utm_source=openai))\n\n3. **Download Streams**  \n   - It downloads the selected video and/or audio streams. Sometimes YouTube (or other platforms) store high-res audio and video separately (e.g. video stream without audio). yt-dlp handles fetching both. ([github.com](https://github.com/yt-dlp/yt-dlp/wiki/Extractors?utm_source=openai))\n\n4. **Post-Processing (if needed)**  \n   - Merging streams: if video and audio are separate, yt-dlp uses **ffmpeg** to merge them together into one playable file (MP4, MKV, etc.). ([github.com](https://github.com/yt-dlp/yt-dlp/wiki/FAQ?utm_source=openai))  \n   - Converting formats: e.g. extracting audio only (`-x`), convert to MP3/M4A/FLAC/etc. ([yt-dlp-yt-dlp.mintlify.app](https://yt-dlp-yt-dlp.mintlify.app/quickstart?utm_source=openai))  \n   - Embedding metadata (title, description, thumbnail, chapters), subtitles, etc. ([yt-dlp-yt-dlp.mintlify.app](https://yt-dlp-yt-dlp.mintlify.app/quickstart?utm_source=openai))  \n\n5. **Handling Restrictions**  \n   - For age-restricted, members-only, region-locked, or private videos, cookies from a logged-in browser session may be needed. yt-dlp can accept cookies with `--cookies` or `--cookies-from-browser`. ([github.com](https://github.com/yt-dlp/yt-dlp/wiki/Extractors?utm_source=openai))  \n   - Also, YouTube sometimes uses PO Tokens (protection tokens) \u2014 these are newer, and yt-dlp may require setting up the extractor for a \u201cclient\u201d that supports a PO Token. ([github.com](https://github.com/yt-dlp/yt-dlp/wiki/Extractors?utm_source=openai))\n\n---\n\n## Basic Usage\u2014Commands & Options\n\nHere\u2019s how you interact with yt-dlp from the terminal (Windows, macOS, Linux).\n\n### Installation\n\n- You can get a standalone binary, install via `pip`, or use package managers like Homebrew. ([github.com](https://github.com/zhxtl/yt-dlp/blob/master/README.md?utm_source=openai))  \n- To update: `yt-dlp -U` (if using a binary) or `pip install -U yt-dlp` if you installed via pip. ([github.com](https://github.com/zhxtl/yt-dlp/blob/master/README.md?utm_source=openai))  \n\n### Downloading Basics\n\n- Download a single video at default (best available quality):\n  \n  ```\n  yt-dlp \"https://www.youtube.com/watch?v=VIDEO_ID\"\n  ```\n\n- Download audio-only and convert to MP3:\n\n  ```\n  yt-dlp -x --audio-format mp3 \"https://www.youtube.com/watch?v=VIDEO_ID\"\n  ```\n\n- Specify destination filename/template:\n\n  ```\n  yt-dlp -o \"~/Videos/%(title)s-%(id)s.%(ext)s\" \"VIDEO_URL\"\n  ```\n\n- Download specific formats (resolution limits, e.g., up to 1080p):\n\n  ```\n  yt-dlp -f \"bestvideo[height<=1080]+bestaudio/best[height<=1080]\" \"VIDEO_URL\"\n  ```\n\n- List formats first:\n\n  ```\n  yt-dlp -F \"VIDEO_URL\"\n  ```\n\n### Advanced / Playlist / Channel\n\n- Download all videos in a playlist or channel:\n\n  ```\n  yt-dlp \"PLAYLIST_URL\"\n  ```\n\n- Skip downloading items you've already got (avoiding duplicates) with an archive file:\n\n  ```\n  yt-dlp --download-archive archive.txt \"PLAYLIST_URL\"\n  ```\n\n- Subtitles: automatic or uploaded, and whether to embed them:\n\n  ```\n  yt-dlp --write-auto-subs --sub-lang en \"VIDEO_URL\"\n  yt-dlp --write-subs --embed-subs --sub-lang en \"VIDEO_URL\"\n  ```\n\n---\n\n## Considerations & Limitations\n\n- Always obey **YouTube\u2019s terms of service**. Downloading content without permission may violate those terms or copyright laws.  \n- Some videos are protected by regional restrictions, age limits, or require membership. You\u2019ll often need valid cookies or tokens for access.  \n- Quality: higher quality often means larger file, more bandwidth, and possibly more processing (merging audio/video).  \n- Updates: YouTube often changes how video streaming info is accessed; yt-dlp must update extractors regularly. Using an outdated version can lead to failures. ([github.com](https://github.com/yt-dlp/yt-dlp/wiki/Extractors?utm_source=openai))  \n\n---\n\nIf you like, I can give you real command examples tailored to your operating system (Windows vs macOS vs Linux), or show how to download age-restricted or private videos. Do you want that?"
