准备
平台：64位 Ubuntu 16
源码： ffmpeg-4.1.3.tar.bz2 （https://ffmpeg.org/releases/）
交叉编译器：android-ndk-r17c-linux-x86_64.zip （https://dl.google.com/android/repository/android-ndk-r17c-linux-x86_64.zip ）注意：源码与交叉编译器需要配套，否者会编译失败。这里选的版本是通过编译的版本。

解压文件
创建 ffmpeg 目录
mkdir ~/ffmpeg
解压 ffmpeg-4.1.3.tar.bz2
tar xvf ffmpeg-4.1.3.tar.bz2 -C ~/ffmpeg/
解压 android-ndk-r17c-linux-x86_64.zip
unzip android-ndk-r17c-linux-x86_64.zip -d ~/ffmpeg/
解压结果
进入 ffmpeg-4.1.3/
cd ffmpeg-4.1.3/
- 编写编译脚本
