How to compile latest FFmpeg Library for Android?

Question

Struggling to put together a working and generally best practice build of current FFmpeg. There seems to be no up-to-date documents or tutorials. What does exist is full of outd

Answer 1

Build the standalone NDK Toolchain

Download the latest NDK and run make_standalone_toolchain.py

Configure FFmpeg

./configure \
--cross-prefix=arm-linux-androideabi- \
--sysroot="${ANDROID_STANDALONE_NDK}/sysroot" \
--target-os=linux \
--arch=arm \
--cpu=cortex-a8 \
--enable-cross-compile \
--enable-pic \
--enable-shared \
--extra-cflags="-fpic"

Then of course

make -j4

You probably don't want to compile a lot of the components, so you'll need to see what to enable/disable in ./configure --help

Answer 2

After reading so many post, I've managed to find the way to generate the ffmpeg library for an android

Download below mentioned code and having it as ffmpeg.sh and execute the same in your ffmpeg source root folder and do make

#!/bin/bash
BASEDIR=$(pwd)
TOOLCHAIN_PREFIX=/opt/android-ndk-r9b/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64
CFLAGS='-U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -fno-strict-overflow -fstack-protector-all'
LDFLAGS='-Wl,-z,relro -Wl,-z,now -pie'

./configure \
--target-os=linux \
--cross-prefix=/opt/android-ndk-r9b/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi- \
--arch=arm \
--cpu=armv7-a \
--enable-runtime-cpudetect \
--sysroot=/opt/android-ndk-r9b/platforms/android-9/arch-arm/ \
--enable-pic \
--enable-pthreads \
--enable-cross-compile \
--disable-debug \
--disable-ffserver \
--enable-version3 \
--enable-hardcoded-tables \
--disable-ffplay \
--disable-ffprobe \
--enable-gpl \
--enable-yasm \
--disable-doc \
--disable-shared \
--enable-static \
--extra-cflags="-I${TOOLCHAIN_PREFIX}/include $CFLAGS" \
--extra-ldflags="-L${TOOLCHAIN_PREFIX}/lib $LDFLAGS"
