linux下安装ffmpeg的详细教程

免编译，直接下载二进制可执行文件可访问下面链接进行下载：

John Van Sickle - FFmpeg Static Buildshttps://johnvansickle.com/ffmpeg/

一、centos 下安装ffmpeg

1、下载解压

wget http://www.ffmpeg.org/releases/ffmpeg-5.1.tar.gz
tar-zxvf ffmpeg-4.1.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-5.1
./configure --prefix=/usr/local/ffmpeg
make&&makeinstall

3、配置变量

vi /etc/profile# 在最后PATH添加环境变量：exportPATH=$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&&makeinstall

若运行 ffmpeg -i 报错误：

ffmpeg: error while loading shared libraries: libiconv.so.2: cannot open shared object file: No such file or directory

原因：

明显就是没有 libiconv.so.2

解决办法：

#下载libiconvwget 
https://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.16.tar.gz
tar-zxvf libiconv-1.16.tar.gzcd libiconv-1.16 
#编译安装
./configure --prefix=/usr/local
make
make_install
ln-s /usr/local/lib/libiconv.so.2 /usr/lib/libiconv.so.2
ldconfig

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

sudoapt-get update 
sudoapt-getinstall deb-multimedia-keyring 
sudoapt-getinstall ffmpeg
