VDR is an application that allows us to do video streaming using as source a DVB-S or DVB-T adapter. This guide was tested on CentOS 6.4 x64. I used VDR version 1.7.22 and version 0.5.2 of streamdev server plugin. A prerequisite is that the system must have installed a DVB adapter.
Let’s install some groups and packages
yum groupinstall "Additional Development" "Development tools"
yum install fontconfig fontconfig-devel freetype freetype-devel gettext gettext-devel libcap libcap-devel libjpeg libjpeg-devel

sed -i 's/\(^SELINUX=\).*/\SELINUX=disabled/' /etc/sysconfig/selinux
sed -i 's/\(^SELINUX=\).*/\SELINUX=disabled/' /etc/selinux/config
