# Video Summary Skill Intelligent video summarization for multi-platform content. Supports Bilibili, Xiaohongshu, Douyin, YouTube, and local video files. ## What It Does - **Auto-detect platform** from URL (Bilibili/Xiaohongshu/Douyin/YouTube) - **Extract subtitles/transcripts** using platform-specific methods - **Generate structured summaries** with key insights, timestamps, and actionable takeaways - **Multi-format output** (plain text, JSON, Markdown) - **Direct LLM integration** — outputs ready-to-use summaries - **Automatic cleanup** — no temp file leaks --- ## Quick Setup **No API key required to run.** This skill extracts video content and outputs structured requests for summarization. The agent (or external tool) handles LLM calls. ```bash # Optional: If you want the agent to call LLM for summarization export OPENAI_API_KEY="your-api-key-here" export OPENAI_BASE_URL=https://open.bigmodel.cn/api/paas/v4 # Optional: Whisper model for transcription (default: base) export VIDEO_SUMMARY_WHISPER_MODEL=base ``` **How it works:** 1. Script extracts video subtitles/transcript 2. Script outputs a structured summary request (JSON/text) 3. Agent or external tool calls LLM API with the request 4. Script does NOT directly call any external APIs ### Supported LLM Providers - **OpenAI**: https://platform.openai.com/api-keys - **Zhipu GLM**: https://open.bigmodel.cn/ - **DeepSeek**: https://platform.deepseek.com/ - **Moonshot**: https://platform.moonshot.cn/ Just set OPENAI_BASE_URL to the provider's API endpoint. ### Cookie Configuration (Optional) Xiaohongshu and Douyin may need cookies for some videos: ```bash # Set cookie file path export VIDEO_SUMMARY_COOKIES=/path/to/cookies.txt # Or use --cookies flag video-summary "https://xiaohongshu.com/..." --cookies cookies.txt ``` **⚠️ Cookie Security Note:** - Cookie files contain session tokens and are sensitive - Only use cookies from your own browser sessions - Do not share cookie files with others - Cookie files are read locally and never transmitted externally by this script ### Manual Trigger If configuration is incomplete, say: > "help me configure video-summary" --- ## Quick Start ### Check Dependencies ```bash # Check all required tools yt-dlp --version && jq --version && ffmpeg -version # If missing, install pip install yt-dlp apt install jq ffmpeg # or: brew install jq ffmpeg ``` ### Basic Usage ```bash # Standard summary video-summary "https://www.bilibili.com/video/BV1xx411c7mu" # With chapter segmentation video-summary "https://www.youtube.com/watch?v=xxxxx" --chapter # JSON output for programmatic use video-summary "https://www.xiaohongshu.com/explore/xxxxx" --json # Subtitle only (no AI summary) video-summary "https://v.douyin.com/xxxxx" --subtitle # Save to file video-summary "https://www.bilibili.com/video/BV1xx" --output summary.md # Use cookies for restricted content video-summary "https://www.xiaohongshu.com/explore/xxxxx" --cookies cookies.txt ``` ### In OpenClaw Agent Just say: > "Summarize this video: [URL]" The agent will automatically: 1. Detect the platform 2. Extract video content 3. Generate a structured summary --- ## Commands Reference | Command | Description | |---------|-------------| | `video-summary "<url>"` | Generate standard summary | | `video-summary "<url>" --chapter` | Chapter-by-chapter breakdown | | `video-summary "<url>" --subtitle` | Extract raw transcript only | | `video-summary "<url>" --json` | Structured JSON output | | `video-summary "<url>" --lang <code>` | Specify subtitle language (default: auto) | | `video-summary "<url>" --output <path>` | Save output to file | | `video-summary "<url>" --cookies <file>` | Use cookies file | | `video-summary "<url>" --transcribe` | Force Whisper transcription | --- ## How It Works ### Platform Support Matrix | Platform | Subtitle Extraction | Notes | |----------|-------------------|-------| | **YouTube** | Native CC + auto-generated | Best support | | **Bilibili** | Native CC + backup methods | Requires video ID extraction | | **Xiaohongshu** | Limited (OCR fallback) | No native subtitles, uses transcription | | **Douyin** | Limited (OCR fallback) | Short-form video, may need transcription | | **Local files** | Whisper transcription | Supports mp4, mkv, webm, mp3, etc. | ### Supported URL Formats **YouTube:** - `https://www.youtube.com/watch?v=xxxxx` - `https://youtu.be/xxxxx` **Bilibili:** - `https://www.bilibili.com/video/BV1xx411c7mu` - `https://www.bilibili.com/video/av123456` **Xiaohongshu:** - `https://www.xiaohongshu.com/explore/xxxxx` - `https://xhslink.com/xxxxx` (short link) **Douyin:** - `https://www.douyin.com/video/xxxxx` - `https://v.douyin.com/xxxxx` (short link) ### Processing Pipeline ``` URL Input ↓ Platform Detection ↓ Subtitle Extraction (yt-dlp / Whisper) ↓ Content Chunking (if long) ↓ LLM Summarization (OpenAI API / Agent) ↓ Structured Output ↓ Auto Cleanup ``` --- ## Performance Estimation ### Whisper Transcription Time | Video Duration | tiny | base | small | medium | |---------------|------|------|-------|--------| | 5 min | ~30s | ~1m | ~2m | ~4m | | 15 min | ~1.5m | ~3m | ~6m | ~12m | | 30 min | ~3m | ~6m | ~15m | ~30m | | 60 min | ~6m | ~12m | ~30m | ~60m | **Notes:** - GPU significantly faster (3-10x) - `base` model recommended for balance - First run downloads model (~150MB for base) ### Subtitle Extraction Time | Platform | Time | Notes | |----------|------|-------| | YouTube | ~5s | Direct subtitle download | | Bilibili | ~5s | Direct subtitle download | | Xiaohongshu | ~3m | Requires transcription | | Douyin | ~2m | Requires transcription | --- ## Advanced Configuration ### Whisper for Transcription For platforms without native subtitles (Xiaohongshu, Douyin), install Whisper: ```bash pip install openai-whisper ``` Then configure: ```bash export VIDEO_SUMMARY_WHISPER_MODEL=base # tiny, base, small, medium, large ``` ### OpenAI API for Summarization **This script does NOT directly call LLM APIs.** It outputs structured requests for the agent to process. If you want the agent to call LLM for summarization, configure: ```bash # Optional: API key for your LLM provider export OPENAI_API_KEY="your-api-key-here" # Optional: Custom API endpoint (for non-OpenAI providers) export OPENAI_BASE_URL=https://open.bigmodel.cn/api/paas/v4 # Zhipu # export OPENAI_BASE_URL=https://api.deepseek.com/v1 # DeepSeek # export OPENAI_BASE_URL=https://api.moonshot.cn/v1 # Moonshot # Optional: Model selection export OPENAI_MODEL=gpt-4o-mini ``` **Without API key:** Script outputs transcript and structured request. Agent handles summarization. ### Cookie Configuration for Restricted Content Some platforms require authentication for certain content: ```bash # Method 1: Command line video-summary "https://www.xiaohongshu.com/explore/xxxxx" --cookies cookies.txt # Method 2: Environment variable export VIDEO_SUMMARY_COOKIES=/path/to/cookies.txt ``` **How to get cookies:** 1. Install browser extension: "Get cookies.txt LOCALLY" 2. Login to the platform 3. Export cookies to file ### Custom Summary Prompt Create `~/.video-summary/prompt.txt`: ```markdown # Summary Template ## Key Insights - List 3-5 core arguments ## Key Information - Data, cases, quotes ## Action Items - Specific actions viewers can take ## Timestamp Navigation - Key moments with timestamps and descriptions ``` --- ## Output Formats ### Standard Output (default) ```markdown # Video Title **Duration**: 12:34 **Platform**: Bilibili **Author**: Tech Creator ## Core Content This video explains... ## Key Points 1. Point one 2. Point two 3. Point three ## Timestamps - 00:00 Introduction - 02:15 Core concept - 08:30 Case study - 11:45 Summary ``` ### JSON Output (`--json`) ```json { "title": "Video Title", "platform": "bilibili", "duration": 754, "author": "Creator Name", "summary": "Core content summary...", "keyPoints": ["Point 1", "Point 2", "Point 3"], "chapters": [ {"time": 0, "title": "Intro", "summary": "..."}, {"time": 135, "title": "Core Concept", "summary": "..."} ], "transcript": "Full transcript text..." } ``` --- ## Technical Details ### Dependencies | Tool | Required | Purpose | |------|----------|---------| | **yt-dlp** | Yes | Video/subtitle downloader | | **jq** | Yes | JSON processing | | **ffmpeg** | Yes | Audio/video processing | | **whisper** | Optional | Local transcription | ### File Structure ``` ~/.openclaw/workspace/skills/video-summary/ ├── SKILL.md # This file ├── scripts/ │ └── video-summary.sh # Main CLI script ├── prompts/ │ ├── summary-default.txt │ └── summary-chapter.txt └── references/ └── platform-support.md # Detailed platform notes ``` ### Environment Variables | Variable | Default | Description | |----------|---------|-------------| | `OPENAI_API_KEY` | - | **Optional** - API key for LLM summarization (used by agent, not this script) | | `OPENAI_BASE_URL` | `https://api.openai.com/v1` | **Optional** - Custom API endpoint | | `OPENAI_MODEL` | `gpt-4o-mini` | **Optional** - Model for summarization | | `VIDEO_SUMMARY_WHISPER_MODEL` | `base` | Whisper model size | | `VIDEO_SUMMARY_COOKIES` | - | **Optional** - Path to cookies file (read locally only) | --- ## Troubleshooting ### "No subtitles found" - The video may not have subtitles/CC - Try `--transcribe` to use Whisper - For Xiaohongshu/Douyin, transcription is required ### "yt-dlp: command not found" ```bash pip install yt-dlp # or brew install yt-dlp ``` ### "Missing required dependencies" ```bash # Install all dependencies pip install yt-dlp apt install jq ffmpeg # Ubuntu/Debian # or brew install jq ffmpeg # macOS ``` ### "Video too long" Long videos (>1h) are automatically chunked: - Split into 10-minute segments - Summarize each segment - Merge into final summary ### "Failed to fetch video info" - Video may be private or deleted - Try `--cookies` for restricted content - Region-locked videos may not work ### "Rate limited" - Too many requests to platform - Wait a few minutes - Use `--cookies` for authenticated access --- ## Comparison | Feature | OpenClaw summarize | video-summary | |---------|-------------------|---------------| | YouTube | ✅ | ✅ | | Bilibili | ❌ | ✅ | | Xiaohongshu | ❌ | ⚠️ (transcription) | | Douyin | ❌ | ⚠️ (transcription) | | Chapter segmentation | ❌ | ✅ | | Timestamps | ❌ | ✅ | | Transcript extraction | ❌ | ✅ | | JSON output | ❌ | ✅ | | Save to file | ❌ | ✅ | | Cookie support | ❌ | ✅ | --- ## References - [Platform Support Details](references/platform-support.md) - [yt-dlp Documentation](https://github.com/yt-dlp/yt-dlp) - [OpenAI Whisper](https://github.com/openai/whisper) --- ## Contributing Found a bug or want to add platform support?
