In this how to i will describe how to install ffmpeg, mplayer, mencoder, flvtool2, ffmpeg-php with all supported codecs to convert / manipulate videos easily on CentOS 5.x. If you want to run sites like youtube e.g www.indianpad.in, www.danceindiadance.in this howto will help you to install the base for your software. There are many other way to perform this but this works for me, so i want to share.

RPMForge repository (http://dag.wieers.com) is the biggest rpm respository for RHEL, CentOS for all versions. To enable RPMForge respository run following command to install all necessary files for getting RPMForge repository. The following command directly install rpm from http://da.wieers.com site.

For i386/i686

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

For x86_64

rpm -Uhv [http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS//rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm](http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS//rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm)

This rpm will add necessary files in our repository configuration and can be viewed at **/etc/yum.repos.d/rpmforge.repo**

Now we have rpmforge repository, so we will use yum to install ffmpeg, mplayer, mencoder as well as all dependent software.

yum -y install ffmpeg ffmpeg-devel mplayer mencoder flvtool2

This command will some time to download and install all packages depends on your internet speed.
