linux下安装ffmpeg的详细教程

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 && 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
[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

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libiconv

wget https://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.16.tar.gz
tar -zxvf libiconv-1.16.tar.gz
cd 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

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