从 YouTube、Bilibili 或 SJTU Canvas 课堂实录的讲座、教程或技术分享视频生成专业、详尽、配图丰富的 LaTeX 课程笔记与最终 PDF。当用户提供 YouTube 链接（youtube.com/watch、youtu.be 等）、Bilibili 链接（bilibili.com/video/BV 号、b23.tv 短链）、SJTU Canvas 课程链接（oc.sjtu.edu.cn/courses/<id>）或 v.sjtu.edu.cn play-center 实录分享链接，并希望获得结构化中文教学笔记时使用——笔记需结合视频标题、章节、图表、公式、代码与字幕讲解，首页放置视频原始封面，从可用的最高分辨率源中抽取关键帧作为插图，最终交付物必须包含渲染完成的 PDF。无 CC 字幕可用时回退到本地 ASR 转写（asr skill）。.
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
# Video Render PDF 把一个 YouTube、Bilibili 或 SJTU Canvas 课堂实录的讲座视频变成一份完整可编译的中文 `.tex` 笔记和渲染好的 PDF。各平台共用一条流水线，差异只在素材获取。 ## 环境 新机器先跑 `scripts/setup.sh` 一键装齐（幂等）；之后每次开工 `scripts/doctor.sh` 体检。ctex 字体集优先 `fontset=fandol`，缺字体时按平台退回 `mac`/`windows`。以下零依赖脚本（`python3`/`bash` 直跑）固化流水线的机械环节，别每次重推命令： - `link-get --media <URL> -o <dir>`：meta.json → cover → 可下载最高清晰度 video.mp4 → CC 字幕尝试（Bilibili 拿不到时追加 `BBDown --sub-only` 回退，登录态下含 AI 字幕）→ 无字幕自动抽 audio.wav 供 ASR 转写 - `link-get <课程URL> [--lecture N] -o <dir>`：SJTU Canvas 课堂实录入口，PAT 认证免 cookie。不带 --lecture 时先列讲次清单（带 cour_id、已下载与不可点播标记）再选；默认取 PPT 录屏机位（viewNum 5/6，最适合抽帧做笔记），`--camera all` 可拿全部机位；`v.sjtu.edu.cn` play-center 分享链接直接可用（本地解密 teclId 反查教学班）；`--cover-at` 指定封面抽帧时刻（默认 120s，课前常是签到/待机画面，建议取第一页标题 slide 时段）。平台 AI 字幕常未就绪，产物固定含 audio.wav。轻量用途：`--list-courses`/`--files`/`--announcements`/`--assignments` 直走 Canvas REST，不用 LTI、不下视频——「有没有作业/课件」这类问题别再走完整流水线 - `scripts/frames.py timeline|scan|grab|desub`：全片接触表建 slide 时间轴；字幕带安静度扫描找无硬字幕时刻（`--band auto` 自动定带）；定点抽帧并拼候选表；desub 三档去烧录字幕：`median` 快路径 / `auto` 先测带内覆盖率再分派（clean-frames 或逐像素重建，需 `uv run --with numpy`）/ `rebuild` 强制重建 …

How to install
mdr add wncfht/agent-basic-skill/video-render-pdf@sha256:9e5d2944bad60869The line at the top of this page pins the label git:20261018.c0ddc34, 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.
