[CentOS_7.4]Linux编译安装ffmpeg

安装过程： 下载安装源，配置，编译，安装，设置环境变量。

# wget http://www.ffmpeg.org/releases/ffmpeg-3.1.tar.gz
# tar -zxvf ffmpeg-3.1.tar.gz
# cd ffmpeg-3.1
# ./configure --prefix=/usr/local/ffmpeg
# make && make install

等待安装完成...

# vi /etc/profile
在最后PATH添加环境变量：
PATH=$PATH: /usr/local/ffmpeg/bin
export  PATH
保存退出

# source /ect/profile   设置生效
# 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
[email protected] 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

　　

结束！
