Archlinux: Compile ffmpeg with nonfree codecs

The ffmpeg binaries that are present in the official repository of Archlinux are not compiled with nonfree codecs. Some excellent ones like libfaac, libx264 and lib-nonfree are not included by default. However, with AUR and its package building automation tool yaourt, one can easily accomplish this. Here are the steps...

1. Install yaourt using pacman -S yaourt, if you haven't already.
2. Key in yaourt -Sb ffmpeg, and answer 'Yes' when asked for confirmation. Remember, you'd have to edit PKGBUILD when asked for. Add --enable-nonfree and --enable-libfaac and other needed configuration options to the build() function, exit the editor, and proceed.
3. That's it, get yourself a cup of tea while the compilation process to finishes, and you're good to go.
