媒体处理工具集（基于 ffmpeg）。当用户需要视频转码、格式转换、压缩到指定大小、调整分辨率/帧率、添加 Logo 或图片水印、设置水印位置/尺寸/透明度、追加片头片尾、音频处理、视频裁剪/剪辑、合并/拼接、修复 m3u 下载损坏视频（faststart/moov atom）时使用。支持品牌视频一体化生成、目标 MB 两遍编码、H.264/H.265/AV1/VP9 批量转码、无损裁剪与合并、mp4 moov 前置修复。.
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
# Media Use - 媒体处理工具集 基于 ffmpeg 的媒体处理工具集，提供 5 个独立 CLI：转码、品牌包装、裁剪、合并、修复。 ## 准备 ```bash cd media-use/scripts uv sync ``` 所有命令通过 `uv run <工具>` 执行。依赖：Python 3.13+、ffmpeg / ffprobe（需预先安装）。 ## 工具列表 ### ffmpeg_batch —— 批量视频转码 多种编码格式 + GPU 硬件加速，支持递归、并行、预览。 ```bash # 转码为 H.264 4Mbps，音频直接复制 uv run ffmpeg_batch /path/to/source /path/to/target -vc h264 -vb 4M # NVIDIA GPU 加速转码 H.265 uv run ffmpeg_batch /path/to/source /path/to/target -vc hevc-nvenc -vb 5M --hwaccel-decode # 查看支持的编码器 uv run ffmpeg_batch --list-codecs ``` 常用参数：`-vc/--video-codec`、`-ac/--audio-codec`、`-vb/--video-bitrate`、 `-ab/--audio-bitrate`、`--hwaccel-decode`、`-s/--suffix`、`-r/--recursive`、 `-e/--ext`、`-j/--jobs`、`--dry-run`、`--list-codecs`。 ### ffmpeg_brand —— 水印、片尾与目标体积压缩 为单个视频添加图片或文字水印、追加片尾，并统一输出尺寸、帧率和编码。设置 `--target-mb` 时自动按主视频与片尾总时长计算码率，使用 H.264 两遍编码并预留 5% 封装余量；若第一次结果仍超出目标，会自动降低视频码率重试一次。 第一遍编码通过 Python 的 `os.devnull` 使用系统空设备（Windows 为 `NUL`），因此 Windows 可直接使用 `--target-mb`。 ```bash # 480P / 30fps，左下角半透明 Logo，并追加片尾 uv run ffmpeg_brand input.mp4 \ --watermark logo.png \ --outro outro.mp4 \ --height 480 --fps 30 \ --watermark-position bottom-left \ --watermark-opacity 0.45 \ …

How to install
mdr add zrong/skills/media-use@sha256:628ab4331fe7aa3fThe line at the top of this page pins the label git:20260806.3af2ea6, 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.
