# AndroidFFmpegLibrary
This project aims to create **working** library providing playing and converting video files in android via ffmpeg libraries.
We rather want to use ffmpeg library without modifications to facilitate updating of ffmpeg core.

## Info
This project aim to simplify compilation of FFmpeg for android different architectures to one big apk file.

## Moved source code
I moved project source code to our company review system https://review.appunite.com
because I am used to benefit from review systems like Gerrit. There you can find newest not yet accepted source code. If you do not care of newest source code or contributing software you can just use github where you can reaches accepted
commits.

git clone https://review.appunite.com/androidffmpeg
	
or

git clone https://github.com/nxtreaming/AndroidFFmpeg.git

FFmpeg, libvo-aacenc, vo-amrwbenc, yuv2rgb and others libraries projects are distributed on theirs own license.

## Patent disclaimer
We do not grant of patent rights.
Some codecs use patented techniques and before use those parts of library you have to buy thrid-party patents.

## Pre-requirments
on mac: you have to install xcode and command tools from xcode preferences
you have to install (on mac you can use brew command from homebrew):
you have to install:
- autoconf
- autoconf-archive
- automake

on Debian/Ubuntu - you can use apt-get

on Mac - you can use tool brew from homebrew project. You have additionally install xcode.

## Mac only
glibtoolize: 
because the Xcode 4.5.2 fails to supply glibtoolize,
but freetype2 depends on it, just copy your 'libtoolize' to 'glibtoolize',
Such as:

sudo cp /usr/local/bin/libtoolize /usr/local/bin/glibtoolize

## Installation

### Before start
if you have a problem with certificate add *GIT\_SSL\_NO\_VERIFY=true* before git submodule update line

GIT_SSL_NO_VERIFY=true  git submodule update

Im sorry about this certificate issue, but never is enough time to fix problems like those

**If you have ssh key in our review system** you should setup global alias in *~/.gitconfig* file.

git config --global url.ssh://review.appunite.com.insteadOf https://review.appunite.com

### Go to the work
downloading source code

git clone https://review.appunite.com/androidffmpeg AndroidFFmpeg
	cd AndroidFFmpeg
	git submodule init
	git submodule sync #if you are updating source code
	git submodule update
	cd FFmpegLibrary
	cd jni

setup freetype2 environemtn

cd freetype2
	./autogen.sh
	cd ..

setup fribidi environemtn

cd fribidi
	autoreconf -ivf
	cd ..

setup libass environemtn

cd libass
	autoreconf -ivf
	cd ..

setup vo-aacenc environment

cd vo-aacenc
	autoreconf
	cd ..

setup vo-amrwbenc environment

cd vo-amrwbenc
	autoreconf
	cd ..

build external libraries

export NDK=/your/path/to/android-ndk
	./build_android.sh
	
make sure that files FFmpegLibrary/libs/{armeabi,armeabi-v7a,x86}/libffmpeg.so was created, otherwise you are in truble

build ndk jni library

ndk-build

build your project

android update lib-project -p FFmpegLibrary
	android update project -p FFmpegExample
	cd FFmpegExample
	ant debug
	ant installd

or create new projects from FFmpegLibrary and FFmpegExample source directories in your eclipse. 
Run FFmpegExample as your android project.
If you have adt >= 20.0 you can click right mouse button on project and FFmpegLibrary project and "Android->Add native support".

## More codecs
If you nead more codecs:
- edit build_android.sh
- add more codecs in ffmpeg configuration section
- remove old ffmpeg-build directory by

rm -r ffmpeg-build
	
- build ffmpeg end supporting libraries

./build_android.sh
		
	During this process make sure that ffmpeg configuration goes without error.
	
	After build make sure that files FFmpegLibrary/libs/{armeabi,armeabi-v7a,x86}/libffmpeg.so was created, otherwise you are in truble

- build your ndk library

ndk-build

- refresh your FFmpegLibrary project in eclipse!!!!
- build your FFmpegExample project
