> FFmpeg 的基本组成

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。它包括了领先的音/视频编码库libavcodec等。

libavformat：用于各种音视频[封装格式][Link 1]的生成和解析，包括获取解码所需信息以生成解码上下文结构和读取音视频帧等功能；

libavcodec：用于各种类型声音/图像编解码；

libavutil：包含一些公共的工具函数；

libswscale：用于视频场景比例缩放、色彩映射转换；

libpostproc：用于后期效果处理；

ffmpeg：该项目提供的一个工具，可用于格式转换、解码或[电视卡][Link 2]即时编码等；
