Mac OS下安装ffmpeg和ffplay(简单版)

前言

FFmpeg是一套可以用来记录、转换数字音频、视频，并能将其转化为流的开源计算机程序。采用LGPL或GPL许可证。它提供了录制、转换以及流化音视频的完整解决方案。它包含了非常先进的音频/视频编解码库libavcodec，为了保证高可移植性和编解码质量，libavcodec里很多code都是从头开发的

同时它是一个开源项目，可以将任何格式的音视频文档进行编解码转换播放等等等等，基本可以这么说你对音视频相关的任何需求她都能办到，但首先你得会用她。开源领域内神一样的VLC，还有Media Player Classic都是在用ffmpeg的codec库。

在Mac上安装linux社区的软件常用有两种方式：一、使用MacPorts；二、使用Homebrew，因为我用的是brew所以只说用它安装的方式。

一、安装Homebrew

参考本文：Mac 安装 brew （2020最新，不报错）

二、使用brew安装ffmpeg：

$ brew install ffmpeg --with-ffplay
或者直接使用brew install ffmpeg自动会安装ffplay

除了安装选项 --with-ffplay外还有更多的选项如下：
