centos linux下安装ffmpeg

1、下载解压

wget http://www.ffmpeg.org/releases/ffmpeg-3.1.tar.gz

tar -zxvf ffmpeg-3.1.tar.gz

2、 进入解压后目录,输入如下命令/usr/local/ffmpeg为自己指定的安装目录

cd ffmpeg-3.1

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

make && make install

3、配置变量

vi /etc/profile

在最后PATH添加环境变量：

export PATH=$PATH:/usr/local/ffmpeg/bin

保存退出

查看是否生效

source /ect/profile  设置生效

4、查看版本

ffmpeg -version    查看版本

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.

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
