Retry with alternate InnerTube client identities when YouTube returns
anti-bot responses, then fall back to yt-dlp when available. Split
monolithic main.ts into typed modules (youtube, transcript, storage,
shared, types) and add unit tests.
- Guard last chapter end against duration=0: use Math.max(duration, ch.start)
- Remove unnecessary 'as any' cast in backfill
- Check all chapters for missing end (not just first) via .some()
- Skip backfill when needsFetch is true (about to refetch anyway)
- Wrap backfill writeFileSync in try/catch (best-effort persistence)
Videos cached before the chapter end-time change would silently
lack the 'end' field when loaded from cache. This adds a migration
that detects missing 'end' fields on cache hit, computes them from
adjacent chapters, and persists the updated meta.json.
This ensures consistent output regardless of whether the data was
freshly fetched or loaded from cache.
Add 'end' field to Chapter interface and parseChapters output.
Each chapter's end is derived from the next chapter's start time,
with the last chapter ending at the video's total duration.
This makes chapter data complete and ready for downstream consumers
(e.g. video clipping with ffmpeg) without requiring them to compute
end times from adjacent chapters.
Before: { title: 'Overview', start: 0 }
After: { title: 'Overview', start: 0, end: 21 }
