| # 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 \ |
| # --enable-external-build |
| # |
| # 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 jni/libvpx/build/make/Android.mk |
| # |
| # By default libvpx will use the 'cpufeatures' module from the NDK. This allows |
| # the library to be built with all available optimizations (SSE2->AVX512 for |
| # x86, NEON for arm, DSPr2 for mips). This can be disabled with |
| # --disable-runtime-cpu-detect |
| # but the resulting library *must* be run on devices supporting all of the |
| # enabled extensions. They can be disabled individually with |
| # --disable-{sse2, sse3, ssse3, sse4_1, avx, avx2, avx512} |
| # --disable-neon[-asm] |
| # --disable-{dspr2, msa} |
| |
| # |
| # Running ndk-build will build libvpx and include it in your project. |
