linux下安装ffmpeg

一、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

二、debian 安装 ffmpeg

1、编辑/etc/apt/sources.list加入

deb http://www.deb-multimedia.org jessie main

2、安装ffmpeg

sudo apt-get update
sudo apt-get install deb-multimedia-keyring
sudo apt-get install ffmpeg
