How to Install ffmpeg, ffmpeg-php and codecs automagically

A client recently requested ffmpeg to be installed on the server. I have done this in the past on a client's box but he had a different OS setup.

Everyone loves automagic installations! After the first failure I bumped into a forum that let's you download a tarball and install ffmpeg without any hitches and within 20 minutes. This attempt did work!

Pros and Cons of Auto Installer

Con: The downside to the ffmpeg auto install script, you end up downloading and installing many ffmpeg related libraries you might not need.
Pros: No errors and installtions works as expected (at least for my setup).

There are a few things you should know before you get started:
Must be a Linux/Unix/POSIX server
Must need root shell(bash) access
Must need 200 MB of free space in your server
The author of this gpl ffmpeg auto install script will know your server ip (see below how to remove this) upon installation.
Check if yum is installed or not in the server. If there is no yum, please make sure automake,autoconf and libtools are installed. It is reccommend to configure the distribution specific yum.

Setup Installation

First, open up SSH (I like using putty) and login as "root". Once there, run the below commands:
mkdir ~/ffmpeg-packages
cd ~/ffmpeg-packages
wget http://trulymanaged.com/ffmpeg/ffmpeginstaller.tar.gz
tar -xvzf ffmpeginstall.tar.gz
cd ffmpeginstall

Now let's begin the installation process
./install.sh

Once the installation starts you will see the verbose messages, letting you know the status of the installation.
