# 一、安装ffmpeg
分为两种安装方式:
### 1. 命令行安装
```
brew install ffmpeg
```
### 2. 下载压缩包安装
去 http://evermeet.cx/ffmpeg/ 下载7z压缩包,解压缩后,将ffmpeg文件拷贝到一个地方,然后在bash_profile里面配置好环境变量
# 二、安装ffplay
分为两种安装方式:
### 1. 命令行安装
执行下面的命令就可以进行安装操作
```
brew install ffmpeg --with-ffplay
```
> - 注:目前使用此安装方式安装后,执行ffplay会出现command not found的问题,可能是因为SDL的配置问题导致的。
### 2. 下载压缩包安装
去 http://evermeet.cx/ffmpeg/ 下载7z压缩包,解压缩后,将ffplay文件拷贝到一个地方,然后在bash_profile里面配置好环境变量
