Video and audio encoding for playback in Android and iOS devices

This document aims to provide an easy way encode video optimized for playback in mobile devices that use the Android or the iOS operating systems.

libx264 is used for (single or two-pass) video encoding and libfdk_aac for audio encoding.

ffmpeg, libx264 and libfdk_aac settings are optimized for playback quality and compatibility on Android and iOS. There is extensive documentation and references for each of the settings used and contributions are very welcome :)

Loading variables from .env files in Ansible

Ansible has various ways of looking up data from outside sources, including plain text password files, CSV files and INI files. But it doesn't seem to have a lookup for .env files, as used in Laravel projects, also available for PHP, Ruby, Node.js, Python and others.

One option is to launch Ansible with the Ruby dotenv command line script... But that requires Ruby, which seems like overkill to me.

So here is a simpler solution that I use. It consists of:

1. The .env file itself
2. A small shell script that loads the .env file into environment variables - ansible-playbook.sh
