1. SSH into your instance and become root
sudo su -

2. Go to the the /usr/local/bin directory
cd /usr/local/bin

3. Inside the /usr/local/bin directory, create an "ffmpeg" directory
mkdir ffmpeg

4. Go into the new directory
cd ffmpeg

5. Go to static build directory at http://ffmpeg.gusari.org/static/64bit/ and pick the 
latest version of FFMPEG - as of this writing, it was ffmpeg.static.64bit.2014-02-16.tar.gz
wget http://ffmpeg.gusari.org/static/64bit/ffmpeg.static.64bit.2014-02-16.tar.gz

6. The file should now be in /usr/local/bin/ffmpeg. Untar it...
tar -xzf ffmpeg.static.64bit.2014-02-16.tar.gz

5. Run it and check what the latest version is 
./ffmpeg -version
6. If you want to be able to execute FFMPEG from any directory, simply create a symlink into /usr/bin like this:
ln -s /usr/local/bin/ffmpeg/ffmpeg /usr/bin/ffmpeg
ln -s /usr/local/bin/ffmpeg/ffprobe /usr/bin/ffprobe

The first part (/usr/local/bin/ffmpeg/ffmpeg) is where the file is located after I untarred 
the file. The second part (/usr/bin/ffmpeg) is where we want the symlink to go

$ brew install ffmpeg --force
$ brew link ffmpeg
