前言:

做音视频领域相关开发或者二次开发，绕不开的几个工具，ffmpeg,mediainfo巴拉巴拉。

当然都支持跨平台，并且很多很好的媒体软件都能看到他们的影子。

话不多说，开始安装步骤(这里以centos7为例):

1.查看系统版本

cat /etc/redhat-release

2.下载所需依赖

wget https://mediaarea.net/download/binary/mediainfo/21.03/mediainfo-21.03.x86_64.CentOS_7.rpm
wget https://mediaarea.net/download/binary/libmediainfo0/21.03/libmediainfo-debuginfo-21.03.x86_64.RHEL_7.rpm
wget https://mediaarea.net/download/binary/libzen0/0.4.39/libzen-0.4.39.x86_64.CentOS_7.rpm

3.依次安装

rpm -ivh libzen-0.4.39.x86_64.CentOS_7.rpm 
rpm -ivh libmediainfo-21.03.x86_64.CentOS_7.rpm
rpm -ivh mediainfo-21.03.x86_64.CentOS_7.rpm

4.验证

mediainfo -i audio.flac --OUTPUT=XML > test.xml

结果:
