写个脚本，放入以下：

yum install -y vim
yum install -y epel-release
sudo rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
yum repolist
sudo rpm –import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm
yum repolist
yum install -y ffmpeg
ffmpeg -version

运行即可

---

如果之后错误为：

ffmpeg: error while loading shared libraries: libusb-1.0.so.0: cannot open shared object file: No such file or directory

那么：

yum install libusb1
