我是靠谱客的博主俭朴哈密瓜，这篇文章主要介绍ubuntu20源码编译安装ffmpeg准备工作配置ffmpeg编译、安装，现在分享给大家，希望可以做个参考。

准备工作

ubuntu要安装一下必要工具，比如：

复制代码

# gcc, g++工具链
sudo apt-get install gcc g++
#Makefile
sudo apt-get install make
#安装git
sudo apt-get install git

下载ffmpeg源码：

复制代码

git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg

配置ffmpeg

cd ffmpeg/
./configure --enable-libmp3lame 
--enable-libfdk-aac 
--enable-gpl 
--enable-nonfree 
--enable-libx264 
--enable-libx265 
--enable-ffplay 
--disable-static 
--enable-shared 
--prefix=/home/lorien/work/media/ffmpeg/install

通过configure命令来生成Makefile，–prefix参数是配置软件安装最终目录。

配置可能会失败，提示缺失依赖组件，缺什么补什么就行，大致安装如下以来组件：

复制代码

# 汇编编译
sudo apt-get install yasm
# libfdk-aac
sudo apt-get install libfdk-aac-dev
# x264
sudo apt-get install libx264-dev
# x265
sudo apt-get install libx265-dev
# ffplay使用，缺少这个，不会生成ffplay
sudo apt install libsdl2-dev
# libmp3lame-dev
sudo apt-get install libmp3lame-dev

注意： libsdl2-dev库是生成ffplay工具用的，如果缺少这个lib，编译能成功，但不会生成ffplay工具。

编译、安装

执行

复制代码

1
2
3
make -j4
make install

上述命令执行完之后，编译产物会安装到prefix参数指定的路径下面，我设置的是：/home/lorien/work/media/ffmpeg/install

接下来，将bin/和lib/路径添加到环境变量，方便使用ffmpeg工具，执行如下：

复制代码

sudo vim ~/.bashrc
# 在文件末尾添加两行
export PATH=$PATH:/home/lorien/work/media/ffmpeg/install/bin
export LD_LIBRARY_PATH=/home/lorien/work/media/ffmpeg/install/lib
source ~/.bashrc

下面就可以体验使用ffmpeg工具了：

ffplay test.mp4
