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：
