Turn a Bilibili video into a complete, compileable .tex note and a rendered PDF.
This skill extends the youtube-render-pdf workflow with Bilibili-specific adaptations.
Read ../video-render-common/writing-and-figures.md for all writing rules, teaching content rules, figure handling, figure time provenance, and visualization guidelines. These rules are mandatory.
| Aspect | Handling |
|---|---|
| Subtitle scarcity | CC subtitles → Whisper speech-to-text → visual-only mode |
| Login-gated HD | 1080P+ requires cookies; use yt-dlp --cookies-from-browser chrome |
| Multi-part videos | Detect 分P videos, ask user which parts to process |
| URL formats | bilibili.com/video/BVxxxxxxx and b23.tv short links |
| Danmaku | Do not use danmaku as teaching content (too noisy) |
Same as youtube-render-pdf — produce a professional Chinese lecture note with cover image, key frames, and synthesis section.
Same as youtube-render-pdf — search for official slides AND official lecture notes before downloading video.
Additional Bilibili-specific notes:
/export/pdf URL pattern; fall back to video frames if export failsPriority 1: CC subtitles
yt-dlp --write-subs --sub-langs "zh-Hans,zh-CN,zh,ai-zh" --convert-subs srt \
--skip-download -o "%(title)s.%(ext)s" "<URL>"
Priority 2: Whisper speech-to-text
yt-dlp -x --audio-format wav -o "audio.%(ext)s" "<URL>"

Priority 3: Visual-only mode — skip subtitles, rely on dense frame sampling.
