# This file is to be used for compiling libvpx for Android using the NDK.
|
||||
# In an Android project place a libvpx checkout in the jni directory.
|
||||
# Run the configure script from the jni directory. Base libvpx
|
||||
# encoder/decoder configuration will look similar to:
|
||||
# ./libvpx/configure --target=armv7-android-gcc --disable-examples \
|
||||
# --sdk-path=/opt/android-ndk-r6b/
|
||||
#
|
||||
# When targeting Android, realtime-only is enabled by default. This can
|
||||
# be overridden by adding the command line flag:
|
||||
# --disable-realtime-only
|
||||
#
|
||||
# This will create .mk files that contain variables that contain the
|
||||
# source files to compile.
|
||||
#
|
||||
# Place an Android.mk file in the jni directory that references the
|
||||
# Android.mk file in the libvpx directory:
|
||||
# LOCAL_PATH := $(call my-dir)
|
||||
# include $(CLEAR_VARS)
|
||||
# include libvpx/build/make/Android.mk
|
||||
#
|
||||
# There are currently two TARGET_ARCH_ABI targets for ARM.
|
||||
# armeabi and armeabi-v7a. armeabi-v7a is selected by creating an
|
||||
# Application.mk in the jni directory that contains:
|
||||
# APP_ABI := armeabi-v7a
|
||||
#
|
||||
# By default libvpx will detect at runtime the existance of NEON extension.
|
||||
# For this we import the 'cpufeatures' module from the NDK sources.
|
||||
# libvpx can also be configured without this runtime detection method.
|
||||
# Configuring with --disable-runtime-cpu-detect will assume presence of NEON.
|
||||
# Configuring with --disable-runtime-cpu-detect --disable-neon will remove any
|
||||
# NEON dependency.
|
||||
|
||||
# To change to building armeabi, run ./libvpx/configure again, but with
|
||||
# --target=arm5te-android-gcc and modify the Application.mk file to
|
||||
# set APP_ABI := armeabi
|
||||
#
|
||||
# Running ndk-build will build libvpx and include it in your project.
