FFmpeg-Android

This repo updates the work done in WritingMinds/ffmpeg-android to work with newer versions of FFmpeg. Primary focus will be armv7-neon, since I have a project that requires it.

• FFmpeg for Android compiled with x264, libass, fontconfig, freetype and fribidi
• All libraries are pulled down as git submodules or from svn (as is the case for Lame)
• FFmpeg can be optionally compiled with libnewtek_ndi (doesn't work...see below)
• Supports Android L

Note about libnewtek_ndi

Unfortunately, the version of libndi provided by NewTek wasn't compiled with the Android NDK, and has a dependency to pthread, which isn't available on Android. I'm leaving support for it in the scripts...just in case NewTek releases updated libraries in a future SDK.

Supported Architecture

• armv7-neon
• armv7 (currently disabled in build)
• x86 (currently disabled in build)

Instructions

The build process has been tested on Ubuntu 18.04, but should work for other distributions.

• Set the following environment variables (NEWTEK_NDI_SDK is optional):

export ANDROID_NDK={Android NDK Base Path}
export NEWTEK_NDI_SDK={Newtek NDI Linux SDK Base Path}

• Run the following commands to compile FFmpeg:

sudo apt-get --quiet --yes install build-essential git subversion autoconf libtool pkg-config gperf gettext yasm python-lxml docbook2x
./init_update_libs.sh
./android_build.sh

• To pull down the latest versions of all libraries, you can run the following commands:

git submodule update --recursive --remote
svn up lame-svn

• The compiled executables will be stored in the /build directory.
• If you want to use FONTCONFIG then you need to specify your custom fontconfig config file (e.g - "FONTCONFIG_FILE=/sdcard/fonts.conf ./ffmpeg --version", where /sdcard/fonts.conf is location of your FONTCONFIG configuration file).
