Download videos or playlists with yt-dlp; fetch subtitles/captions, extract audio, choose formats or quality, and troubleshoot access restrictions. Use when asked to save online media, transcripts, or audio.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# yt-dlp media workflow Use `yt-dlp` for media the user is authorized to access. Work in the user's requested output directory; otherwise ask where to save if ambiguous, or use the current working directory when appropriate. Quote URLs and paths. Never print cookies, tokens, or signed media URLs in the response. ## Before downloading 1. Check `command -v yt-dlp; yt-dlp --version; command -v ffmpeg; command -v ffprobe`. `ffmpeg`/`ffprobe` are needed for merging, remuxing, subtitle conversion and audio extraction. If unavailable, explain the limitation rather than promising a merged or converted file. 2. Clarify only missing consequential choices (single video versus whole playlist, output destination, format or language) if they cannot be inferred. A URL with a playlist parameter is **not** consent to download the entire playlist; use `--no-playlist` unless a playlist was requested. …

How to install
mdr add linuztx/alter-zero/yt-dlp@sha256:843859abf84bf5e2The line at the top of this page pins the label git:20261005.1a65edb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
