安装ffmpeg

一、centos linux下安装ffmpeg

1、下载解压

1 2	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

1 2 3

cd ffmpeg-3.1 ./configure --prefix=/usr/local/ffmpeg make && make install

3、配置变量

1 2 3 4 5 6

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

1	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
