Bilibili Media Grabber: Covers, BV/AV IDs & Danmaku in One Pass

Bilibili videos carry more assets than the video file: high-res cover art (the thumbnail, often 1080p+), the BV/AV identifier pair (BV is current, AV is legacy -- both resolve), danmaku XML, and metadata (title, uploader, stats, description). A proper downloader grabs the bundle: video + cover + danmaku + metadata JSON -- because the cover is the thumbnail for your archive and the metadata is how you find it in 3 years.

BV vs AV: Bilibili migrated from AV (numeric, av170001) to BV (alphanumeric, BV1xx411c7mD) years ago; every video has both, interconvertible via algorithm. Tools should accept either. Cover extraction: the API exposes the cover URL directly -- no screenshotting needed, full resolution. Danmaku: paginated XML by video CID (each part/episode has its own CID -- multi-part videos need per-part fetching).

Batch patterns: favorites/collections (grab entire watch-later lists), uploader archives (all videos by a creator -- the channel-backup use case), and series (bangumi/donghua episodes with correct ordering). Rate limiting: Bilibili throttles aggressive fetching -- polite delays (1-2s between requests) and session cookies keep you unblocked. Personal archiving of content you watch; respect creators rights -- no reuploading.

The metadata JSON is the underrated asset: title, description, tags, upload date, view/danmaku counts, uploader info -- this is what makes a 500-video archive searchable instead of a folder of cryptic BV numbers. Good downloaders write it alongside; great ones embed it in the MKV. Future-you will thank present-you for the metadata discipline.

The uploader-archive strategy: for creators you follow closely, periodic full archives (quarterly) capture videos before deletion or platform issues -- Bilibili creators do delete older content, and copyright strikes remove videos without warning. An archive with covers, danmaku, and metadata is a personal library; without the bundle, it is just files. The collectors who regret are the ones who grabbed video-only.

The cookie-authenticated tier: logged-in sessions unlock 1080p+ and 4K qualities that anonymous fetching cannot reach -- the downloader should support cookie import (browser extension export) for full quality access. This is legitimate credential use (your own account); the quality difference between anonymous 720p and authenticated 4K is the difference between an archive and a compromise.
