Convert Douyin/TikTok video audio to text with timestamps, supporting both interactive UI and command-line workflow.

Capabilities: Video parsing, audio extraction, ASR transcription, timestamp generation

Trigger: User provides Douyin/TikTok URL and requests transcription

Usage Modes

Mode 1: Web UI (Recommended)

Visual interface for transcription management:

# Install dependencies
cd skills/good-TTvideo2text
pip install -r requirements.txt

# Start service (default port 8000)
python app/main.py

# Browser access
http://localhost:8000

Features:

• Paste video URL for instant transcription
• View results with timestamps
• Cookie management for restricted videos
• Real-time progress updates

Mode 2: Script (Command Line)

Suitable for automation, AI workflow integration:

# Basic usage
python scripts/transcribe.py "https://v.douyin.com/xxx"

# Extract URL from share text
python scripts/transcribe.py "7.47 复制打开抖音，看看【用户名】的作品 https://v.douyin.com/xxx"

# JSON output
python scripts/transcribe.py "https://v.douyin.com/xxx" --output json

# Text output (default)
python scripts/transcribe.py "https://v.douyin.com/xxx" --output text

Output Format (Text):

=== Video Info ===
Title: Video title
Author: Author name
Duration: 30s

=== Transcription ===
Full Text:

Sentences with Timestamps:
[00:00-00:03] First sentence
[00:03-00:06] Second sentence

Output Format (JSON):

{
  "success": true,
  "video_info": {
    "title": "Video title",
    "author": "Author name",
    "duration": 30,
    "create_time": 1234567890
  },
  "transcription": {
    "text": "Complete transcription...",
    "sentences": [
      {
        "start_ms": 0,
        "end_ms": 3000,
        "text": "First sentence"
      }
    ]
  }
}

Prerequisites

Dependencies:

• fastapi>=0.120.3, uvicorn>=0.35.0, httpx>=0.28.1
• TikTokDownloader dependencies (see requirements.txt)

ASR Configuration:

• Environment variables auto-injected by Goodable platform
• GOODABLE_ASR_SUBMIT_URL - ASR task submission endpoint
• GOODABLE_ASR_QUERY_URL_TEMPLATE - ASR result query endpoint (with {task_id} placeholder)

Cookie Configuration (Optional):

• Some videos require login cookies
• Configure via Web UI Settings or edit TikTokDownloader/settings.json
• Cookie format: Douyin web cookie string

Standard Workflow (AI Usage)

When User Provides URL

1. Extract URL from input:

   • User may provide raw URL or share text with URL
   • Use regex to extract actual video URL

2. Call transcribe script:

   python scripts/transcribe.py "USER_PROVIDED_TEXT"
   

3. Handle results:

   • Success: Present transcription text and timestamps
   • Error: Check error message for troubleshooting

Common Error Handling

| Error | Cause | Solution | |-------|-------|----------| | Invalid video URL | URL format incorrect | Ask user to provide valid Douyin/TikTok URL | | Video not found | Video deleted or requires login | Ask user to check video or provide cookies | | No audio found | Video has no background music | Inform user this video has no audio track | | ASR not configured | Environment variables missing | Run via Goodable platform (auto-injects vars) | | ASR timeout | Long audio or service slow | Retry or use Web UI for monitoring |

Resource Index

• scripts/transcribe.py - Command-line transcription script
• TikTokDownloader/ - Video parsing library (source code)
• TikTokDownloader/settings.json - Cookie and configuration
• static/index.html - Web UI interface
• requirements.txt - Python dependencies
• downloads/ - Temporary file directory

Important Notes

1. Cookie Requirement: Public videos work without cookies, restricted videos need login cookies
2. ASR Platform: This skill requires Goodable platform's ASR service integration
3. URL Formats Supported:
   • Short URL: https://v.douyin.com/xxx
   • Full URL: https://www.douyin.com/video/1234567890
   • TikTok: https://vm.tiktok.com/xxx, https://www.tiktok.com/@user/video/xxx
4. Audio Extraction: Extracts background music URL directly (no download needed)
5. ASR Processing Time: Typically 5-30 seconds depending on audio length
