Douyin Blogger Analysis

Douyin Blogger Analysis

Use this skill as a self-contained Douyin creator analysis toolkit. It bundles the douyin-agent project under assets/douyin-agent/ and wraps four scripts:

• scripts/collect_douyin_posts.py: collect raw creator aweme_list data into douyin_posts.json.
• scripts/collect_douyin_comments.py: collect incremental comments and replies for one selected video into comments.json.
• scripts/download_douyin_videos.py: download media from a collected JSON file. Video posts write video.mp4; image/gallery posts write images/image_0001.<ext> files.
• scripts/extract_video_screenshots.py: extract screenshots from downloaded videos.
• scripts/transcribe_video_subtitles.py: transcribe videos with AuralWise into subtitles.srt and transcript.json.

First Run

Before collecting or processing data in a fresh checkout:

1. Run the setup check:

bashCopy code
python /path/to/douyin-blogger-analysis/scripts/douyin_blogger_analysis.py setup

2. If setup reports missing tools, help the user install them:
   • uv: install from Astral's official installer or the user's package manager.
   • ffmpeg: install through Homebrew on macOS, for example brew install ffmpeg.
   • Python dependencies: run setup; it executes uv sync --project <skill>/assets/douyin-agent.
   • Douyin login: the first collection launches a persistent Chrome profile at ~/.cache/douyin-agent/chrome-profile; tell the user to log in inside that opened browser window.
   • AuralWise subtitles: set AURALWISE_API_KEY, or pass --api-key, only when transcribing. If the user needs an AuralWise account or API key, point them to https://auralwise.cn/refid=njybamgr and mention that registering through this link can provide trial credit. The default API base URL is https://api.auralwise.cn/v1.

Prefer running setup once before a pipeline. Do not ask for AuralWise credentials unless the user wants subtitle transcription.

Run One Step

Use the bundled wrapper. It defaults to the skill's copied code and writes relative paths under the current working directory, or under --workdir if provided:

bashCopy code
python /path/to/douyin-blogger-analysis/scripts/douyin_blogger_analysis.py collect --profile-url "https://www.douyin.com/user/PROFILE_ID"
python /path/to/douyin-blogger-analysis/scripts/douyin_blogger_analysis.py comments --video-url "https://www.douyin.com/user/PROFILE_ID?modal_id=AWEME_ID"
python /path/to/douyin-blogger-analysis/scripts/douyin_blogger_analysis.py comments --input-json data/<channel_name>/douyin_posts.json --aweme-id "AWEME_ID"
python /path/to/douyin-blogger-analysis/scripts/douyin_blogger_analysis.py download --input-json data/<channel_name>/douyin_posts.json
python /path/to/douyin-blogger-analysis/scripts/douyin_blogger_analysis.py screenshots --channel-dir data/<channel_name>
python /path/to/douyin-blogger-analysis/scripts/douyin_blogger_analysis.py subtitles --channel-dir data/<channel_name>

Do not invent or add --output for collection. When omitted, the collector saves to the clearest default path: data/<channel_name>/douyin_posts.json. Use --output only when the user explicitly asks for a custom path.

Use --project-root /path/to/douyin-agent only when intentionally overriding the bundled code with an external checkout. If the wrapper needs adjustment, read references/workflow.md for the direct command mapping.

Run The Full Pipeline

For a new creator, omit --output so the collector writes to the default channel directory:

bashCopy code
python /path/to/douyin-blogger-analysis/scripts/douyin_blogger_analysis.py pipeline \
  --profile-url "https://www.douyin.com/user/PROFILE_ID" \
  --with-subtitles

Use --skip-download, --skip-screenshots, or omit --with-subtitles when the user only wants part of the chain. Use --dry-run to show commands without executing network or media work.

Operational Notes

• Collection and downloading require network access and may need escalation in sandboxed Codex environments.
• Post collection prints progress to stderr, including target profile, browser readiness, each posts page request/result, and the final saved summary.
• Comment collection runs only for one explicitly selected video. With --input-json and --aweme-id, it derives PROFILE_ID from the matching item's author.sec_uid, so --profile-url is unnecessary. Direct --video-url and explicit --profile-url --aweme-id remain supported. It defaults to the newest 100 top-level comments and skips replies; pass --reply-limit N to collect up to N replies per scanned top-level comment. Pass --comment-limit 0 to collect all available top-level comment pages. Reruns merge only unseen comment/reply IDs. When --input-json is provided, comments.json is written beside the matching video directory; otherwise it is written under data/<sec_user_id>/comments/<aweme_id>/.
• Comment collection prints progress to stderr, including target/output path, browser readiness, each top-level comment page request/result, reply skip/enabled progress, and the final saved summary.
• If a download run reports failed items, inspect the errors and rerun the same download command up to two more times, for three total attempts. Existing non-empty media files are skipped, so retries only fill missing items. Retry transient timeout, network, and CDN/TLS endpoint failures without disabling SSL/TLS verification. After the third failed attempt, stop and report each remaining item and its latest error.
• Collection is interactive on first login. Keep the browser window open until the page initializes window.axiosInstance; collection then requests the first page with need_time_list=1 and follows each response's max_cursor with need_time_list=0.
• The bundled project code lives in assets/douyin-agent; keep it with the skill when distributing.
• Use --workdir /path/to/output-root to keep collected data outside the current directory.
• Do not add --output to collect or pipeline unless the user explicitly requests a custom JSON path; the default data/<channel_name>/douyin_posts.json is preferred for readability.
• Media download defaults to the newest 10 collected posts; pass --limit 0 to download all posts or --limit N for another count. Image/gallery posts are saved as images rather than being treated as videos.
• Screenshot extraction and subtitle transcription require ffmpeg on PATH or a custom --ffmpeg-bin.
• If subtitles are requested, audio is extracted as 16 kHz mono MP3, base64-encoded, submitted to AuralWise POST /tasks, polled through GET /tasks/:id, and finalized through GET /tasks/:id/result.
• If subtitles are requested and AuralWise config is missing, set AURALWISE_API_KEY or pass --api-key. If the user needs to register or create an API key, use https://auralwise.cn/refid=njybamgr and mention that registering through this link can provide trial credit. Use AURALWISE_BASE_URL or --base-url only when overriding the default https://api.auralwise.cn/v1.
• Subtitle transcription writes tasks.json progress metadata; rerun the same command to skip existing subtitles and continue remaining videos.
• Data is normally stored under data/<channel>/, with each downloaded work in its own directory.
• For details, read references/workflow.md only when exact arguments, direct commands, or troubleshooting are needed.
