One-command YouTube pipeline — downloads media, fetches or transcribes captions, and runs forced alignment. Trigger when the user provides a YouTube URL (youtube.com / youtu.be) and wants captions/subtitles, or says "align youtube", "下载YouTube字幕", "get captions from youtube".

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

# YouTube Workflow

YouTube URL → aligned captions in one command. Requires an API key (`/lai-setup`) and `yt-dlp` (`pip install yt-dlp`).

## File path convention

All outputs land in the **current directory** by default (no subdirectories). Use the YouTube **video ID** as `<base>` and chain pipeline files as `<base>.<derivation>.<ext>`:

```
<base>.mp4              # downloaded media
<base>.en.vtt           # YouTube auto-caption
<base>.meta.md          # metadata
<base>.aligned.json     # forced-alignment output (when caption.output.format=json)
<base>.srt              # final SRT (when caption.output.format=srt)
```

`<base>` is the YouTube ID (e.g. `la0CaZ2R8EY`); the agent extracts it from the URL.

## Basic Command

This command uses `nemo_run` config syntax (`key=value`), **not** `-o / --output`.

```bash
# `<base>` = la0CaZ2R8EY (the YouTube video ID)
lai youtube align "https://youtu.be/la0CaZ2R8EY" \
    caption.output.path=la0CaZ2R8EY.aligned.json \
    caption.output.format=json
# shortcut:
lai-youtube "https://youtu.be/la0CaZ2R8EY" caption.output.path=la0CaZ2R8EY.aligned.json
```

How to install

The exact contents, by fingerprint

mdr add lattifai/lattifai-skills/lai-youtube@sha256:167716dff9455dcc

The line at the top of this page pins the label git:20260428.4ab9c84, 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.
