docker下centos7编译安装ffmpeg

1.安装基础命令

docker下精简版centos没有make等命令，先安装：

yum -y install gcc automake autoconf libtool make

yum install gcc gcc-c++

当然也没有wget

yum install -y wget

还有vim

yum install -y vim

虽然这些不是必须的，但是有会方便很多

2.安装nasm

wget https://www.nasm.us/pub/nasm/releasebuilds/2.13.03/nasm-2.13.03.tar.gz

tar xvf nasm-2.13.03.tar.gz

cd nasm-2.13.03

./configure

make

make install

3.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

4.安装x264

下载地址: http://www.videolan.org/developers/x264.html

下载的包为:last_x264.tar.bz2

tar -jxvf last_x264.tar.bz2 

cd x264-snapshot-20161101-2245 

./configure --enable-shared 

make 

make install

加入环境变量,执行:

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH

5.安装ffmpeg

先去官网下载：https://www.ffmpeg.org/download.html

tar -jxvf ffmpeg-4.2.1.tar.bz2

cd ffmpeg-4.2.1

./configure –enable-shared –prefix=/usr/local/ffmpeg –enable-gpl –enable-libx264

make

make install

配置：

vim /etc/ld.so.conf

打开后加入以下两行：
/usr/local/ffmpeg/lib
/usr/local/lib

让配置生效
ldconfig

创建链接（全局的快捷方式，加入后可以先jdk一样在任意目录下java -version等操作）

ln -s /usr/local/ffmpeg/bin/ffmpeg /usr/local/bin/ 

ln -s /usr/local/ffmpeg/bin/ffprobe /usr/local/bin/ 

ln -s /usr/local/ffmpeg/bin/ffserver /usr/local/bin/

6.测试

输入ffmpeg -version

返回结果：
