Claude Code Skill
本项目提供了 Claude Code Skill,让 AI 编程助手可以直接调用 VideoCaptioner 处理视频。
安装到 Claude Code:
mkdir -p ~/.claude/skills/videocaptioner
cp skills/SKILL.md ~/.claude/skills/videocaptioner/SKILL.md
然后在 Claude Code 中输入 /videocaptioner transcribe video.mp4 --asr bijian 即可使用。
工作原理
音视频输入 → 语音识别 → 字幕断句 → LLM 优化 → 翻译 → 视频合成
- 词级时间戳 + VAD 语音活动检测,识别准确率高
- LLM 语义理解断句,字幕阅读体验自然流畅
- 上下文感知翻译,支持反思优化机制
- 批量并发处理,效率高
