# 视频转字幕与 AI 总结技能

## Overview

将短视频平台（抖音、小红书、B 站、YouTube 等）视频或本地视频/音频文件转换为字幕文本并生成 AI 摘要。

**核心流程：**
- **在线视频：** 获取视频信息 → 下载视频/直接抓字幕 → 选择字幕后端 → 生成字幕 → AI 总结
- **本地文件：** 提取音频（如需） → 选择字幕后端 → 生成字幕 → AI 总结

默认使用本地 `faster-whisper`，也支持通过环境变量切换到火山引擎 VC API。
YouTube 优先使用 `yt-dlp` 直接抓取人工字幕或自动字幕；只有没有可用字幕时，才需要下载音视频并回退到 ASR。
