最简单直接在centos7安装ffmpeg

编译方式安装ffmpeg
1.依赖包安装

yum install autoconf automake gcc gcc-c++ git libtool make nasm pkgconfig zlib-devel -y

2.下载安装源

wget http://www.ffmpeg.org/releases/ffmpeg-4.1.tar.gz

2.1解压缩安装包

tar -zxvf ffmpeg-4.1.tar.gz

cd ffmpeg-4.1

./configure --prefix=/usr/local/ffmpeg

2.2编译安装

make && make install

2.3设置环境变量

echo "export PATH=$PATH:/usr/local/ffmpeg/bin" >> /etc/profile

2.4环境变量生效

source /etc/profile

3.查看版本

ffmpeg -version

PS：注意
若安装过程中出现以下错误：

yasm/nasm not found or too old. Use –disable-yasm for a crippled
build. If you think configure made a mistake, make sure you are using
the latest version from Git. If the latest version fails, report the
problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on
irc.freenode.net. Include the log file “config.log” produced by
configure as this will help solve the problem.

4.需要安装yasm

wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz

tar -zxvf yasm-1.3.0.tar.gz

cd yasm-1.3.0 # ./configure

make && make install

5.yum方式安装ffmpeg
centos7:

rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro

rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm

yum install ffmpeg ffmpeg-devel -y

centos6:

rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
