Install FFMPEG on 3 Servers (Debian 7)

I have three debian 7 servers that require the following: FFmpeg 1.0 or above (prefer the most up to date version) with a minimum of libx264, libavfilter and AAC codec (libfaac, libfdk_aac or native ffmpeg aac codec) installed. FFmpeg is already installed, it will need to be removed or upgraded to meet the above requirements. Current version is 0.8 something, so that is not working. I will set a milestone, release once the 1st server is done. Once the other two are done I will release the rest of the final payment. I will check the installs prior to releasing the payment. The backend script I'm using provides me with the ability to test the install. Any errors I will report to you, you fix then we are all good. This should be a very short and easy project for an individual that knows how to do it. Thanks
