When I try to use extensions/vp9 and follow its readme, VP9 can not be built with android-ndk-r16. the complains are as follows:
build_android_configs:
configure --target=armv7-android-gcc --sdk-path=/data/SDK/NDK/android-ndk-r16 --enable-neon --enable-neon-asm --disable-examples --disable-docs --enable-realtime-only --disable-vp8 --disable-vp9-encoder --disable-webm-io --disable-libyuv --disable-runtime-cpu-detect

Unable to invoke compiler: /data/SDK/NDK/android-ndk-r16/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc --sysroot=/data/SDK/NDK/android-ndk-r16/platforms/android-27/arch-arm -DNDEBUG -O3 -fPIC -Wall -Wdeclaration-after-statement -Wdisabled-optimization -Wfloat-conversion -Wpointer-arith -Wtype-limits -Wcast-qual -Wvla -Wimplicit-function-declaration -Wuninitialized -Wunused -Wextra -Wundef

Configuration failed. This could reflect a misconfiguration of your
toolchains, improper options selected, or another problem. If you
don't see any useful error messages above, the next step is to look
at the configure error log file (config.log) to determine what
configure was trying to do when it died.

The config.log is as follows:

../../libvpx/configure --target=armv7-android-gcc --sdk-path=/data/SDK/NDK/android-ndk-r16 --enable-neon --enable-neon-asm --disable-examples --disable-docs --enable-realtime-only --disable-vp8 --disable-vp9-encoder --disable-webm-io --disable-libyuv --disable-runtime-cpu-detect

It looks like the layout of the sysroot has changed quite a bit in NDK 16 (maybe related to the unified headers migration?). I was able to get it to build by creating a unified toolchain with build/tools/make_standalone_toolchain.py --arch arm --api 26 --install-dir unified-toolchain and setting the output directory as the sysroot.

@vigneshvg Configuration of libvpx fails at the moment with NDK 16, as include files aren't present in the sysroot. Any ideas what the right fix is? Thanks!

Thanks for pointing this out.

It looks like we may have to fix the configure script on upstream libvpx. I've opened a bug for libvpx: https://bugs.chromium.org/p/webm/issues/detail?id=1476

I'll update the instructions to use the updated version of libvpx once that bug is fixed.

While the bug is being taken care of, here is a workaround:

../../libvpx/configure --target=armv7-android-gcc --sdk-path=/data/SDK/NDK/android-ndk-r16 --enable-neon --enable-neon-asm --disable-examples --disable-docs --enable-realtime-only --disable-vp8 --disable-vp9-encoder --disable-webm-io --disable-libyuv --disable-runtime-cpu-detect \
--extra-cflags="-isystem /data/SDK/NDK/android-ndk-r16/sysroot/usr/include/arm-linux-androideabi \
  -isystem /data/SDK/NDK/android-ndk-r16/sysroot/usr/include"

Note that NDK r16 dropped support for android-9.

The pointed NDK version has been told in the VP9 readme and workaround method has been provided. Thanks for all developers ;)

I have the following observations when building libvpx from source v1.7.0 for all the android supported ABI i.e. ABIS=("armeabi" "armeabi-v7a" "arm64-v8a" "x86" "x86_64" "mips" "mips64")
See: https://github.com/cmeng-git/vpx-android

Observation 1:

ANDROID_API=21
NDK=/opt/android/android-ndk-r16b
PREFIX=./output/android/${ABI}

./configure
--sdk-path=${NDK}
--prefix=${PREFIX}
--target=${TARGET}
--disable-runtime-cpu-detect
--disable-docs
--enable-static
--disable-shared
--disable-examples
--disable-tools
--disable-debug
--disable-unit-tests
--enable-realtime-only
--disable-webm-io
--extra-cflags="-isystem ${NDK}/sysroot/usr/include/${NDK_ABIARCH} -isystem ${NDK}/sysroot/usr/include"

Results:

  1. "arm64-v8a" failed half way with
    ....
    [CC] vpx_scale/vpx_scale_rtcd.c.o
    [CC] vpx_ports/arm_cpudetect.c.o

    __uint128_t vregs[32];
    ^
    make[1]: *** [vpx_scale/vpx_scale_rtcd.c.o] Error 1

  2. The build is ok when using NDK=/opt/android/android-ndk-r15c and without the parameter
    --extra-cflags="-isystem ${NDK}/sysroot/usr/include/${NDK_ABIARCH} -isystem ${NDK}/sysroot/usr/include"

Observation 2:

ANDROID_API=21
NDK=/opt/android/android-ndk-r16b or /opt/android/android-ndk-r15c
PREFIX=./output/android/${ABI}

Results:

  1. Both ABI "mips" "mips64" failed to build with ndk r16 or r15 with target sets respectively to
    a. TARGET="mips32-linux-gcc"
    b. TARGET="mips64-linux-gcc"

Configuration failed. This could reflect a misconfiguration of your
toolchains, improper options selected, or another problem. If you
don't see any useful error messages above, the next step is to look
at the configure error log file (config.log) to determine what
configure was trying to do when it died.

and the config.log error is

Observation 3:

ANDROID_API=21
NDK=/opt/android/android-ndk-r15c

Use method as proposed by andrewlewis commented on Nov 30, 2017
build/tools/make_standalone_toolchain.py --arch arm --api 26 --install-dir unified-toolchain and setting the output directory as the sysroot.

Not sure what it means by "output directory as the sysroot"
Instead I set
./configure
--sdk-path='unified-toolchain'

Results:

  1. "arm64-v8a" failed during configuration, apparently got the incorrect ${CC}
    ....
    enabling vp9_decoder
    Configuring for target 'arm64-android-gcc'
    enabling arm64

  2. Both ABI "mips" "mips64" failed as observation Support wider range of DASH manifests #2

There is an error in the vpx configure for arm64-android-gcc etc. Please see below for more information
