1.首先将文件考到linux服务器上并解压，这里安装的版本是ffmpeg-3.3.3
[root@iZbp16etend51sn64ysypiZ local]# ls
aegis bin cloudmonitor curl etc ffmpeg ffmpeg-3.3.3 ffmpeg-3.3.3.zip
2.加载动态库
cd /etc/ld.so.conf.d/
touch ffmpeg.conf
vim ffmpeg.conf 输入/usr/local/ffmpeg/lib
3.加入环境变量
echo -e '\nexport PATH=$PATH:/usr/local/ffmpeg/bin' >> /etc/profile
[root@iZbp16etend51sn64ysypiZ ~]# cat /etc/profile | grep ffmpeg
export PATH=$PATH:/usr/local/ffmpeg/bin
4.安装ffmpeg
chmod -R 755 ffmpeg-3.3.3
cd ffmpeg-3.3.3
./configure --enable-shared --disable-yasm --prefix=/usr/local/ffmpeg
make && make install
5.重新加载动态库
cd /etc/ld.so.conf.d
ldconfig
至此安装完毕，可以使用ffmpeg -v查看版本
[root@iZbp16etend51sn64ysypiZ local]# ffmpeg -v
