linux音频解码软件ffmpeg的安装

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 ' export 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
