（CentOS7） Linux编译编译安装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-4.3.tar.bz2
# tar --jxvf ffmpeg-4.3.tar.bz2
# cd ffmpeg-4.3
# ./configure --prefix=/usr/local/ffmpeg
# make && make install

安装少则三五分钟，多到十多分钟

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

# source /ect/profile   设置生效
# ffmpeg -version       查看版本

 

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
