I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio.

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 :)
