Notes

• Requires yt-dlp to be installed and available in the PATH.
• Works with videos that have closed captions (CC) or auto-generated subtitles.
• If a video has no subtitles, the script will fail with an error message.

整體質量良好，核心功能實現可靠穩定。優點是使用成熟工具yt-dlp作為後端，錯誤處理完善，文件清晰易懂，安裝方便。不足之處是隻能獲取英文字幕，不夠靈活；缺少自動重試等容錯機制。對於需要獲取YouTube影片文字內容的場景，這是一個簡單有效的解決方案。
