视频下载

Download source media only. Do not transcribe, rewrite, edit, or publish it.

Storage rules

• Keep source URLs, source titles, source metadata, and downloaded reference media inside 01-内容生产/视频工作台/.internal/ by default.
• Use 01-内容生产/视频工作台/制作中/<日期-主题>/原始素材/ only when the caller explicitly names a production project and the media is an approved production input.
• Never place source information in a handoff, finished script, final archive, or public document.
• Never overwrite an existing file. Let the downloader add a stable suffix or stop.

Workflow

1. Confirm that the URL is source media and that downloading it is within the user's request.
2. Run the bundled downloader. It uses this order:
   • Douyin: TikHub media URL, then yt-dlp with browser cookies, then plain yt-dlp.
   • Other supported sites: plain yt-dlp, optionally with browser cookies when required.
3. Inspect the returned local path and media probe. A successful HTTP response alone is not delivery.
4. Require a playable audio or video stream and a non-zero duration. Report the local path, duration, dimensions, and selected download method.
5. If every route fails, preserve the concise failure log and state the missing prerequisite. Do not claim that the video was downloaded.

Command

Use the Python interpreter that can import tikhub for the best Douyin path. In this workspace, prefer /opt/homebrew/bin/python3 when available.
