Prerequisites

Docker Whisper (Recommended): \\\\bash docker run -d -p 9000:9000 --name whisper-asr onerahmet/openai-whisper-asr-webservice:latest \\\

Workflow

Step 0: Input Classification

Step 1: Fetch Video

1.1 Resolve Short URL

\\\\bash

Windows PowerShell

curl.exe -sL -o NUL -w "%{url_effective}" "https://v.douyin.com/xxx/"

macOS/Linux

curl -sL -o /dev/null -w '%{url_effective}' "https://v.douyin.com/xxx/" \\\

Output: \https://www.douyin.com/video/7616020798351871284\

1.2 Open Video Page

\\\ browser(action='open', profile='openclaw', url='https://www.douyin.com/video/{VIDEO_ID}') \\\

Wait 10-15 seconds for page to load completely.

1.3 Extract Video URL (Browser DOM Method)

\\\javascript browser(action='act', targetId='PAGE_ID', request={ "kind": "evaluate", "fn": "(() => { const entries = performance.getEntriesByType('resource'); const videoEntries = entries.filter(e => { const name = e.name.toLowerCase(); return name.includes('douyinvod') && (name.includes('.mp4') || name.includes('video')); }); if (videoEntries.length > 0) { const video = videoEntries[videoEntries.length - 1]; return { url: video.name, type: video.name.includes('.mp4') ? 'mp4' : 'dash' }; } return null; })()" }) \\\

Important Notes:

• \ct\ action requires nested \ equest\ object with \kind\ and \\fn\
• Wrong: \\browser(action='act', fn='...')\
• Correct: \\browser(action='act', request={"kind": "evaluate", "fn": "..."})\

1.4 Download Video

\\\\bash curl.exe -L -H "Referer: https://www.douyin.com/" -o video.mp4 "<CDN_URL>" \\\

Referer header is required, otherwise 403.

Step 2: Transcribe Audio

2.1 Extract Audio

\\\\bash

For MP4 videos

ffmpeg -i video.mp4 -ar 16000 -ac 1 -c:a pcm_s16le audio.wav -y

For DASH videos (need merge)

ffmpeg -i video.mp4 -i audio.mp4 -c copy merged.mp4 -y ffmpeg -i merged.mp4 -ar 16000 -ac 1 -c:a pcm_s16le audio.wav -y \\\

Parameters:

• \-ar 16000\: 16kHz sample rate (Whisper requirement)
• \-ac 1\: Mono channel
• \-c:a pcm_s16le\: 16-bit PCM

2.2 Transcribe with Docker Whisper

\\\\bash curl.exe -X POST "http://localhost:PORT/asr" -F "audio_file=@audio.wav" \\\

2.3 Alternative: Local Whisper

\\\\bash python -m whisper audio.wav --model small --language zh \\\

1. Fix transcription errors

- Correct homophones - Fix speaker names - Remove filler words

1. Structure content

- Add paragraph breaks - Create sections

1. Extract key points

- Main ideas - Important quotes

1. Generate tags

- 3-5 topic tags

Step 4: Save Output

摘要

{Summary}

正文

{Transcript content with paragraphs}

要点

• {Key point 1}
• {Key point 2}
• {Key point 3}

标签

#{tag1} #{tag2} #{tag3} \\\

File Naming Convention

\\\ {VIDEO_ID}-抖音转录.md \\\

Troubleshooting

Image Note Handling

Image notes (\/note/\) don't need transcription:

\\\

1. browser(action='open', profile='openclaw', url='IMAGE_NOTE_URL')
2. browser(action='snapshot')
3. Extract content from snapshot
4. Save to output directory

\\\

Edge Cases

• Article links (\/article/\): Use browser snapshot, no transcription
• Douyin AI summary: Extract from page as supplement
• Other platforms: Use yt-dlp for YouTube/Bilibili
• Live streams: Not supported
