+# 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。
