Use when users provide YouTube, Bilibili, or X/Twitter lecture URLs and want reader-first Chinese LaTeX/PDF notes with source-faithful claims, fluent authored prose, and verified teaching figures, especially requests phrased as lecture notes, 视频转PDF, 课程笔记, 讲义, YouTube笔记, B站笔记, X/Twitter lecture notes, or BV号; do not produce transcript dumps, quota-padded prose, or screenshot galleries.
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
# Lecture to Notes Turn a YouTube, Bilibili, or X/Twitter lecture video into a complete, compilable `.tex` note set and a rendered PDF. ## Dependencies Check before starting (use `which`). Prompt the user to install any missing tools. | Tool | Required | Purpose | |------|----------|---------| | `yt-dlp` | Always | Video/subtitle/metadata download (supports YouTube + Bilibili + X/Twitter). Check `yt-dlp --version`: a build older than ~90 days fails on current Bilibili and YouTube pages | | `ffmpeg` | Always | Frame extraction, audio extraction | | `xelatex` | Always | LaTeX compilation (TeX Live + CTeX for Chinese) | | `magick` | Always | Frame montage and contact sheets | | `ffprobe` | Always | Duration and frame height (ships with ffmpeg) | | `pdftotext` | Always | Rendered-page checks in `verify_notes.py` (poppler) | | `python3` | Always | Installed helper scripts and local ASR support | | `sherpa-onnx` + X ASR model | Optional zh/en ASR | Fast local Chinese/English transcription with token timestamps | | Whisper backend | ASR fallback / non-zh-en / no-CC | `transcribe_whisper.py` picks `mlx-whisper` (macOS arm64) → `faster-whisper` → `openai-whisper` | …

How to install
mdr add ysyecust/lecture-to-notes/lecture-to-notes@sha256:a0b6b5ed6d9c9211The line at the top of this page pins the label git:20261031.4a37c8c, 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.
