AI 产品解读Bilibili (B站) video downloader — extracts video metadata from Bilibili pages and enables direct video file download by modifying response headers to force browser download
Users want to download Bilibili videos for offline viewing, but Bilibili does not natively offer a download button. The extension intercepts Bilibili's video CDN streams and sets Content-Disposition headers to 'attachment', triggering file downloads.
1. User installs extension and navigates to a Bilibili video/bangumi page. 2. Content script (video_bilibili_accessible.js) reads video metadata from the page's __INITIAL_STATE__ or __playinfo__. 3. Content script (video_bilibili_content.js) displays download options injected into the page UI. 4. When user clicks download, the popup/background resolves video URLs via Bilibili's player API. 5. declarativeNetRequest rules rewrite the Referer header and set Content-Disposition:attachment on bilivideo CDN requests, forcing the browser to download the video file instead of streaming it. 6. Optionally, the user can convert the downloaded video format via cv.pictureknow.com.

- 目标用户
- Chinese internet users who watch videos on Bilibili and want to download them for offline use / Users browsing Chinese e-commerce platforms (Taobao, Tmall, JD) looking for coupons
- All JS files are minified/webpack-bundled, making it difficult to trace exact application logic beyond keyword scanning
- The coupon_content.js and jd_coupon_content.js files are large React bundles whose specific UI elements cannot be easily inspected
- Cannot confirm whether the popup UI shows any paywall or upgrade prompts without rendering it
付费分析未识别到付费功能
No evidence of paid features, subscription gating, upgrade prompts, or payment platform integration found in the extension source code. Keyword matches for 'pro', 'license', and 'pay' were all false positives from React production builds, MIT license headers, CSS progress elements, and Sizzle.js internals. No Stripe, premium, membership, VIP, subscription, or upgrade keywords were found. The extension appears to be entirely free.

- The extension itself does not implement any login UI, authentication flow, or account system. It works by extracting video metadata directly from Bilibili's page state (window.__INITIAL_STATE__, window.__playinfo__) via a content script injected into bilibili.com video/bangumi pages, and calls api.bilibili.com/x/player/playurl for video URLs. No cookie manipulation, OAuth, password fields, or sign-in UI were found. However, Bilibili (the destination service) may require its own login for higher-quality streams or bangumi content, which is outside the extension's control.
很好用,但是今天怎么不显示下载按钮了呢
一直都很好用,但是现在这两天只能下载1080p的视频了,希望大佬能更新一波,冲!!!
有的视频没法用了 很奇怪
最近老是下载被禁止,没法用
加返利不说明一分送上
看起来可以用饿
下载速度还挺快!希望能根据这个功能出个b站视频防卡顿的子功能。我用b站看视频经常几十KB的速度,用这个插件能有几兆的速度
The extension works great, but since today, the download label doesn't appear now, so I can't download any of the videos. Can this be fixed? 这个扩展很好用,但从今天开始,下载标签现在不出现了,所以我无法下载任何视频。这个问题能得到解决吗?(translation by DeepL)
下载1080p60的时候,下载的.FLV文件到一半儿就停止下载了。
很不错的哔哩哔哩下载插件
