快速提取视频中的背景音乐、人声及音频内容为 MP3/WAV，支持本地视频文件与抖音等平台分享链接（链接经 qhkit 解析成直链后提取），方便二次编辑和内容创作。当用户要求提取视频音频、扒BGM、视频转音频、拿视频里的音乐/口播时必须触发。关键词：LinkPix、qhkit、音频提取、提取BGM、视频转音频、扒音乐、提取人声、视频配乐、MP3提取、ffmpeg。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AI视频音频提取 | 提取背景音乐 | 人声提取 | 视频转音频 | LinkPix
本地 ffmpeg 完成音频提取；素材只有平台分享链接时先用 `qhkit video-inspire` 解析出视频直链再提取。
## 何时触发
- 「把这条视频的音频/BGM 提出来」
- 「视频转 MP3」「拿这条口播的音轨」
## 使用配方
**环境**：需要 ffmpeg。缺失时安装：Linux `apt-get install -y ffmpeg`（或对应包管理器）；macOS `brew install ffmpeg`；Windows `winget install ffmpeg`。
```bash
# 本地文件 / 视频直链 → MP3（-vn 去视频流）
ffmpeg -i "输入视频.mp4" -vn -acodec libmp3lame -q:a 2 输出音频.mp3
# 要无损：-acodec pcm_s16le 输出 .wav
ffmpeg -i "输入视频.mp4" -vn -acodec pcm_s16le 输出音频.wav
```
只有抖音等平台**分享链接**（不是直链）时，先用 qhkit 解析。缺 qhkit（npm 包 `@iqinghu/qhkit`，需 Node ≥ 18）就地安装：`npm i -g @iqinghu/qhkit`（官方源慢或超时时加 `--registry=https://registry.npmmirror.com`）；无密钥（命令返回 `stage:"config"`）时执行 `qhkit config set --token <密钥> --env prod`（让用户在 https://www.iqinghu.com/workbench/login?type=1&urlCode=1788417527636 注册/登录后，到工作台 APIKeys 页 https://www.iqinghu.com/workbench/dashboard/api-keys 创建密钥发给你）：
```bash
qhkit video-inspire generate '{"resourceUrl":"https://v.douyin.com/xxxx/"}'
qhkit video-inspire status '{"inspireTaskId":276}' # 返回里的 playVideo 就是直链
ffmpeg -i "<playVideo 直链>" -vn -acodec libmp3lame -q:a 2 音频.mp3
```
- 交付：给出本地文件路径；当前环境支持文件外发时按渠道约定发送音频文件。
- 顺带产出的 `videoScript`（脚本）如果对用户有用可以一并交付。

How to install
mdr add autoagc/linkpix-skills/linkpix-video-audio-extract@sha256:6ec46e92d13b01a2The line at the top of this page pins the label git:20260908.e0bf7eb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
