Fix broken compile in FFmpeg installer script for Ubuntu 12.04

I have an issue with an ffmpeg installer script that works but only partly, the script is a all-in-one FFMPEG Auto Installer, that cover all the possible media needs, I have used their script once before a few years ago on CentOS, but the last version is old now, and not playing nice on Ubuntu 12.04, its completes 85% of the install but fails near the end where it fails at rebuilding the mplayer after the stage ffmpeg is installed FFMPEG Auto Installer View on [login to view URL] just to make sure you understand, the script install most of the parts and compiles mplayer then compiles ffmpeg, then re-compiles mplayer again to include ffmpeg settings, but that is where it fails. What I am asking for is for you to customize this script by fixing the issue with the build failure as mentioned above, also to amend any dead repository links in the script if any. and have finished script on Github.
