FFmpeg for android for dummies

This repository intent to be an ultimate guide for anyone who needs to build ffmpeg for android.

Motivation

Building applications is not a simple task and become even more complicated for those who does it very seldom, are not used to linux systems and need to cross-compile. The motivation was my personal experience, when I needed a simple FFmpeg version for running a project on android took me longer to sucessfully build ffmpeg than all other project related stuff.

Setting-up

This script was sucessffully tested on a fresh Ubuntu 16.04 VM, all the dependencies and envoirement settings will be done by the script, the user only needs:

1. Download Android NDK
2. Adjust export NDK=/path/to/ndk to point to the right ndk folder

FFmpeg settings
