centos7上安装ffmpeg

方案一：源码安装

1.官网下载http://ffmpeg.org/download.html

 

 2.

tar -xjvf ffmpeg-5.1.2.tar.xz
yum install gcc
yum install yasm  #源码编译yasm
cd ffmpeg-5.1.2
 ./configure --enable-shared --prefix=/usr/local/ffmpeg/ffmpeg-5.1.2
make
make install 

3.修改vim /etc/ld.so.conf.d/ffmpeg.conf，写入：/usr/local/ffmpeg/ffmpeg-5.1.2/lib

4.执行：ldconfig

5.添加到全局变量：

vi /etc/profile

export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig:/usr/local/ffmpeg/ffmpeg-5.1.2/lib/pkgconfig
export FFMPEG_HOME=/usr/local/ffmpeg/ffmpeg-5.1.2
