FFmpeg is an important application software which is used to run a video website with streaming with conversion of video files into various video formats. By following the below steps you can install FFmpeg software easily on Linux VPS Hosting without compiling the files.

yum install ffmpeg

If you will get command not found, then you will have to add few lines in the yum repository for dag installation.

Create a file named dag.repo in /etc/yum.repos.d with the following contents on it

[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
enabled=1

then

yum update

yum install ffmpeg

If everything works fine, then the installation should proceed smoothly and if not then you will get something like warning GPG public key missing .

To fix rpmforge GPG key warning:

rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

Most commonly you have GLIB 2.3 installed instead of GLIB 2.4 version. To check the current GLIB version installed on your server. just use

yum list glib*

and it will list all the packages whether installed or not. Try to see whether Glibc 2.4 installed, if not you will need to upgrade your Centos to latest version of 5.
