一个全面的技能，用于从教程视频中提取章节索引，结合FFmpeg音频提取、OpenAI Whisper ASR转录（含词级时间戳）以及基于模糊字符串匹配的语义章节对齐。
这是一个专为开发者设计的技能，能够自动从教程视频中提取章节索引。其工作流程包括：使用FFmpeg提取音频流，通过OpenAI Whisper ASR进行词级时间戳的转录，然后利用模糊字符串匹配算法将转录结果与预设章节标题进行语义对齐，最终生成带有时间戳的结构化章节索引。该技能支持在Claude Code、Cursor等AI代理平台上运行，尤其适用于视频教育内容的自动化处理，可以显著节省手动标注时间。基于其SKILL.md文档，它易于集成到视频处理管道中，并支持自定义参数，如模型选择和对齐阈值。

This repo contains 3 individual skills — each has its own dedicated page.
Handles audio resampling, loudness normalization per ITU-R BS.1770-4, and LUFS measurement for TTS segments to ensure broadcast-quality output.
Muxes normalized TTS audio segments into the original video at precise time offsets using FFmpeg, and generates the JSON report with timing, drift, and loudness metadata.
Synthesizes target-language speech from text using Kokoro TTS, with speed/duration control to fit precise time windows. Handles SRT parsing, text extraction, and produces WAV segments.
Extract frames or short clips from videos using ffmpeg.
Summarize or transcribe URLs, YouTube/videos, podcasts, articles, transcripts, PDFs, and local files.
Use when testing, fixing, or extending the OpenClaw Control UI GUI with Vitest + Playwright end-to-end checks, mocked Gateway WebSocket flows, mocked dashboard runs, screenshots/videos, or agent-verifiable browser proof.
