一、centos linux下安裝ffmpeg

1、下載解壓

wget http://www.ffmpeg.org/releases/ffmpeg-3.1.tar.gz
tar -zxvf ffmpeg-3.1.tar.gz 

2、 進入解壓後目錄,輸入如下命令/usr/local/ffmpeg為自己指定的安裝目錄

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

3、配置變數

vi /etc/profile
在最後PATH新增環境變數：
export PATH=$PATH:/usr/local/ffmpeg/bin
儲存退出
檢視是否生效
source /ect/profile   設定生效
 

4、檢視版本

ffmpeg -version       檢視版本

注意：

若安裝過程中出現以下錯誤：

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.
 

需要安裝 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 安裝 ffmpeg

1、編輯/etc/apt/sources.list加入

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

2、安裝ffmpeg

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