####安装FFMPEG####
#从repo导入GPG密钥：
rpm --import http://packages.atrpms.net/RPM-GPG-KEY.atrpms
#安装ATRPMS Repo：
rpm -ivh http://dl.atrpms.net/all/atrpms-repo-6-7.el6.x86_64.rpm
#Ffmpeg需要libdc1394-devel，它在epel库中可用。 执行以下命令安装epel存储库：
rpm -Uvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-9.noarch.rpm
#从ATRPMS安装FFMpeg存储库：yum -y --enablerepo=atrpms install ffmpeg ffmpeg-devel
yum -y --enablerepo=atrpms install ffmpeg ffmpeg-devel
#版本
ffmpeg -version
#生成水印
