Run as root to compile FFMpeg with the following Codecs:

• Xvid
• Lame MP3 Codec
• FAAC
• OpenCore AMR Codec
• OGG
• Vorbis
• Theora
• x264
• LibVPX

Preparation for Debian-based systems:

Preparation for RHEL-based systems:

The script has been tested on Debian Wheezy 7.8 and CentOS 6.6.

Things to be added:

• "garbage collection" for downloaded codecs' source code tarballs
• colorful output for the different steps
• normal mode with reduced output from compilation steps
• debugging mode with full output from compilation steps
• options for choosing inbetween different AAC implementations (FAAC, FDK-AAC, libvo-aacenc etc). The default is FAAC.
• function to check if tarballs are taking too much to download and reattempt if this is the case
• implement check for compile-time exit statuses

Here are some examples for testing FFMpeg performace with FAAC: https://trac.ffmpeg.org/wiki/Encode/AAC
