  1. 安装依赖
# yum install autoconf automake bzip2 bzip2-devel cmake freetype-devel gcc gcc-c++ git libtool make pkgconfig zlib-devel libvorbis-devel wget
  1. 建立需要用来存放源码、build和可执行文件的文件夹
# 存放各种组件的源码包
mkdir -p ~/ffmpeg_sources
# 存放编译后的文件
mkdir -p ~/ffmpeg_build

yuv420p

YUV420P又叫plane平面模式，Y , U , V分别在不同平面，也就是有三个平面，它是YUV标准格式4：2：0，主要分为：YU12和YV12
YU12
在android平台下也叫作I420格式，首先是所有Y值，然后是所有U值，最后是所有V值
YV12
YV12格式与YU12基本相同，首先是所有Y值，然后是所有V值，最后是所有U值。只要注意从适当的位置提取U和V值，YU12和YV12都可以使用相同的算法进行处理。

NV12

Compile vlc from source code

本次文档测试的系统为Ubuntu 16.04，很多通过apt install安装的库都很破旧
想要vlc实现解码稀有编码格式必须能够完整地安装vlc，通过snap或apt安装的vlc没有办法以root用户运行，因此只能重新编译vlc，并在编译前配置时加入允许root用户运行的选项(enable-run-as-root)，当然如果转码程序本身可以在不用root用户运行的情况下就能够正常运行的话直接通过snap install vlc就可以（通过apt安装的vlc十分破旧），不需要再按照这个文档编译vlc
