Bilibili All-in-One Skill#

A comprehensive Bilibili toolkit that integrates hot trending monitoring, video downloading, video watching/playback, subtitle downloading, and video publishing capabilities into a single unified skill.

⚠️ Optional Environment Variables: BILIBILI_SESSDATA, BILIBILI_BILI_JCT (optional), BILIBILI_BUVID3 (optional), BILIBILI_PERSIST (optional) These are sensitive Bilibili session cookies needed only for publishing and high-quality (1080p+/4K) downloads. Most features work WITHOUT any credentials: hot monitoring, standard-quality downloads, subtitle listing, danmaku, stats viewing.

📦 Install: pip install -r requirements.txt (all standard PyPI packages: httpx, aiohttp, beautifulsoup4, lxml, requests)

Installation#

Requirements#

• Python >= 3.8
• ffmpeg (optional, for merging video/audio streams)

Install Dependencies#

bash

pip install -r requirements.txt

Dependencies#

• httpx >= 0.24.0
• aiohttp >= 3.8.0
• beautifulsoup4 >= 4.12.0
• lxml >= 4.9.0
• requests >= 2.31.0
• faster-whisper >= 1.0.0 (optional, for speech recognition subtitle fallback)

Configuration#

Some features (downloading high-quality videos, publishing, etc.) require Bilibili authentication. You can provide credentials in three ways:

1. Environment Variables#

bash

export BILIBILI_SESSDATA="your_sessdata"
export BILIBILI_BILI_JCT="your_bili_jct"
export BILIBILI_BUVID3="your_buvid3"

2. Credential File#

Create a JSON file (e.g., credentials.json):

json

{
  "sessdata": "your_sessdata",
  "bili_jct": "your_bili_jct",
  "buvid3": "your_buvid3"
}

3. Direct Parameters#

Pass credentials directly when initializing:

python

from main import BilibiliAllInOne

app = BilibiliAllInOne(
    sessdata="your_sessdata",
    bili_jct="your_bili_jct",
    buvid3="your_buvid3",
)

4. Persistent Storage (Optional)#

By default, credentials are kept in-memory only and are not saved to disk. To enable automatic persistence across sessions:

bash

# Via environment variable
export BILIBILI_PERSIST=1

python

# Or via code
app = BilibiliAllInOne(persist=True)

When persistence is enabled:

• Credentials are auto-saved to .credentials.json (with 0600 permissions) after initialization
• On next startup, credentials are auto-loaded from this file
• You can toggle persistence at runtime: app.auth.persist = True / app.auth.persist = False
• To delete the persisted file: app.auth.clear_persisted()

How to get cookies: Log in to bilibili.com, open browser DevTools (F12) → Application → Cookies, and copy the values of SESSDATA, bili_jct, and buvid3.

⚠️ Security & Privacy#

Credential Handling#

This skill handles sensitive Bilibili session cookies. Please read the following carefully:

ConcernDetailWhat credentials are needed?SESSDATA, bili_jct, buvid3 — Bilibili full browser session cookies (not limited API keys). Providing them grants broad access to your Bilibili account.**Which features require authentication?Publishing (upload/edit/schedule/draft), downloading 1080p+/4K quality videosWhich features work WITHOUT credentials?Hot monitoring, standard-quality downloads, subtitle listing, danmaku fetching, stats viewingWhere are credentials sent?To official Bilibili API endpoints ( api.bilibili.com, member.bilibili.com) over HTTPS onlyAre credentials persisted to disk?**NO by default — credentials stay in memory. Set persist=True or BILIBILI_PERSIST=1 to opt-in to automatic persistence (saved to .credentials.json with 0600 permissions). You can also manually call auth.save_to_file()File permissions for saved credentials0600 (owner read/write only) — restrictive by default

Best Practices#

1. 🧪 Use a test account — Do NOT provide your primary Bilibili account cookies for evaluation/testing purposes. These are full session cookies that grant broad account access (not limited API keys).
2. 🔒 Prefer in-memory credentials — Pass credentials via environment variables or direct parameters rather than saving to a file. Only enable persist=True if you need credentials to survive across sessions.
3. 📁 If you enable persistence — Credentials are saved with 0600 permissions. Use auth.clear_persisted() or auth.persist = False to remove the file when no longer needed.
4. 🐳 Run in isolation — When possible, run this skill in an isolated container/environment and inspect network traffic.
5. 🌐 Verify network traffic — All HTTP requests go to Bilibili's official domains only. You can verify by monitoring outbound connections.
6. ❌ No exfiltration — This skill does NOT send credentials to any third-party service, analytics endpoint, or telemetry server.
7. 🔑 Credential scope — SESSDATA and bili_jct are full session cookies. They are NOT scoped/limited API keys. Treat them with the same care as your account password.

4. 📝 Subtitle ( bilibili_subtitle)#

Download and process subtitles/CC from Bilibili videos. Supports multiple subtitle formats and languages.

When no CC subtitles are available, the module automatically falls back to:

1. Speech Recognition — Downloads the video's audio and transcribes it using faster-whisper (requires pip install faster-whisper)
2. Danmaku Extraction — Fetches bullet comments from the video as a text reference

Both fallback results are returned together when triggered.

Actions

ActionDescriptionParameterslistList available subtitlesurl``downloadDownload subtitles (with auto-fallback)url, language, format, output_dir``convertConvert subtitle formatinput_path, output_format, output_dir``mergeMerge multiple subtitle filesinput_paths, output_path, output_format

Supported Formats

srt (default), ass, vtt, txt, json

Supported Languages

zh-CN (default), en, ja, and other language codes available on the video.

Fallback Strategy

When download is called and no CC subtitles exist:

text

CC Subtitle Available? ──Yes──▶ Download CC subtitle
        │
       No
        │
        ▼
┌─────────────────────────────────────┐
│  Fallback 1: Speech Recognition     │
│  Download audio → faster-whisper    │
│  Output: {title}_transcribed.srt    │
├─────────────────────────────────────┤
│  Fallback 2: Danmaku Extraction     │
│  Fetch bullet comments → SRT        │
│  Output: {title}_danmaku.srt        │
└─────────────────────────────────────┘

Examples

bash

# List available subtitles
python main.py subtitle list '{"url": "BV1xx411c7mD"}'

# Download Chinese subtitles in SRT format (auto-fallback if no CC)
python main.py subtitle download '{"url": "BV1xx411c7mD", "language": "zh-CN", "format": "srt"}'

# Download English subtitles in ASS format
python main.py subtitle download '{"url": "BV1xx411c7mD", "language": "en", "format": "ass"}'
