1. 安装依赖
# macOS
brew install node ffmpeg
# 验证
node -v
ffmpeg -version
2. 配置 API Key
# 在项目 .claude/skills/ 目录下创建 .env 文件
echo "VOLCENGINE_API_KEY=your_key" >> .claude/skills/.env
3. 验证环境
# 检查 Node.js
node -v
# 检查 FFmpeg
ffmpeg -version
# 检查 API Key（在项目目录下执行）
cat .claude/skills/.env | grep VOLCENGINE
常见问题
Q1: API Key 在哪获取？
火山引擎控制台 → 语音技术 → 语音识别 → API Key
Q2: ffmpeg 命令找不到
which ffmpeg # 应该输出路径
# 如果没有，重新安装：brew install ffmpeg
Q3: 文件名含冒号报错
FFmpeg 命令需加 file: 前缀：
ffmpeg -i "file:2026:01:26 task.mp4" ...
