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)
>
> 🔗 Source: github.com/wscats/bilibili-all-in-one

何时激活

当用户明确请求以下 Bilibili 相关操作时，本 Skill 可被激活：

> ⚠️ 注意：本 Skill 不会仅因消息中出现 Bilibili 链接或 BV 号就自动激活。只有当用户明确表达了操作意图（如"下载这个视频"、"查看热门"等）时才会被调用。涉及写操作（发布/编辑）时，需要用户显式提供凭证。

Features

Installation

Requirements

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

Install Dependencies

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

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):

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

3. Direct Parameters

Pass credentials directly when initializing:

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:

# Via environment variable
export BILIBILI_PERSIST=1

# 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:

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.

result = await app.execute("hot_monitor", "get_rank", category="game", limit=10)

2. ⬇️ Downloader (bilibili_downloader)

Download Bilibili videos with support for multiple quality options, batch downloading, and format selection.

Actions

Quality Options

360p, 480p, 720p, 1080p (default), 1080p+, 4k

Format Options

mp4 (default), flv, mp3 (audio only)

Examples

# Get video info
python main.py downloader get_info '{"url": "BV1xx411c7mD"}'

# List available formats
python main.py downloader get_formats '{"url": "BV1xx411c7mD"}'

# Download in 1080p MP4
python main.py downloader download '{"url": "BV1xx411c7mD", "quality": "1080p", "format": "mp4"}'

# Extract audio only
python main.py downloader download '{"url": "BV1xx411c7mD", "format": "mp3"}'

# Batch download
python main.py downloader batch_download '{"urls": ["BV1xx411c7mD", "BV1yy411c8nE"], "quality": "720p"}'

# Python API
info = await app.execute("downloader", "get_info", url="BV1xx411c7mD")
result = await app.execute("downloader", "download", url="BV1xx411c7mD", quality="1080p")

3. 👀 Watcher (bilibili_watcher)

Watch and monitor Bilibili videos. Track view counts, comments, likes, and other engagement metrics over time.

Actions

Supported Platforms

• Bilibili: https://www.bilibili.com/video/BVxxxxxx or BVxxxxxx

Examples

# Get video details
python main.py watcher watch '{"url": "BV1xx411c7mD"}'

# Get current stats
python main.py watcher get_stats '{"url": "BV1xx411c7mD"}'

# Track views every 30 minutes for 12 hours
python main.py watcher track '{"url": "BV1xx411c7mD", "interval": 30, "duration": 12}'

# Compare multiple videos
python main.py watcher compare '{"urls": ["BV1xx411c7mD", "BV1yy411c8nE"]}'

# Python API

comparison = await app.execute("watcher", "compare", urls=["BV1xx411c7mD", "BV1yy411c8nE"])

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

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:

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

# 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"}'

# Convert SRT to VTT
python main.py subtitle convert '{"input_path": "./subtitles/video.srt", "output_format": "vtt"}'

# Merge subtitle files
python main.py subtitle merge '{"input_paths": ["part1.srt", "part2.srt"], "output_path": "merged.srt"}'

# Python API
subs = await app.execute("subtitle", "list", url="BV1xx411c7mD")
result = await app.execute("subtitle", "download", url="BV1xx411c7mD", language="zh-CN", format="srt")

# When no CC subtitles, result includes both fallback outputs:
# result["transcription"]["filepath"]  → speech recognition SRT
# result["danmaku"]["filepath"]        → danmaku SRT
