建在 FFmpeg 上的生态Built on FFmpeg
学习目标LEARNING OBJECTIVES
学完你知道哪些常用工具建在 FFmpeg 上，以及怎么上手。
概念说明CONCEPTS
- HandBrake——转码的图形界面，压缩最常用
- OBS Studio——录制 / 直播的编码层
- Shotcut · Kdenlive——开源剪辑软件，底层就是它
- yt-dlp——音视频分别下载，用它合并
- ffsubsync——字幕自动对齐
上手：macOS brew install ffmpeg；Windows 官网包 → bin 加 PATH。剪辑软件只是给这一层套了个壳。
操作步骤STEPS
- macOS 跑 brew install ffmpeg
- ffmpeg -version 验证
- 挑一张素材跑一条转格式命令
练习PRACTICE
动手任务
安装（或确认已装）FFmpeg，跑 ffmpeg -version 贴出版本号。
自检清单
做完任务后逐条自查，全部能打勾才算过。
常见问题FAQ
为什么要学命令行版？
图形界面是它的壳——壳会换，这一层不会。
HandBrake、OBS 这些和 FFmpeg 什么关系？
都建在这套库上——HandBrake 是命令行转码的图形界面，OBS 的录制直播用它的编码层；剪辑软件只是给这一层套了个壳。
Learning Objectives学习目标
After this card you know which everyday tools sit on FFmpeg and how to get started.
Concepts概念说明
- HandBrake — a GUI wrapper for command-line transcoding; the usual compressor
- OBS Studio — the encoding layer for recording and streaming
- Shotcut · Kdenlive — open-source editors, FFmpeg underneath
- yt-dlp — downloads audio and video separately, merges with it
- ffsubsync — auto-aligns subtitles
Getting started: macOS brew install ffmpeg; Windows: official build → add bin to PATH. An editing app is just a shell wrapped around this layer.
Steps操作步骤
- Install via brew install ffmpeg
- Verify with ffmpeg -version
- Run one conversion on a test clip
Practice练习
Hands-on task
Install FFmpeg (or confirm it) and read one file's codec with ffprobe.
Self-check
Work through the task, then tick every line; all checked means you own this card.
FAQ常见问题
Why learn the command-line version?
The GUIs are shells around it — shells change, this layer doesn't.
How do HandBrake and OBS relate to FFmpeg?
All built on this library — HandBrake is a GUI for command-line transcoding, OBS uses its encoding layer for recording and streaming; editing apps are just a shell around this layer.
