I'm able to build ffmpeg library using NDK r19 when architecture is arm, but compilation fails at libavcodec when architecture is aarch64:
cd ffmpeg && \ CC="aarch64-linux-android21-clang --sysroot /usr/local/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/sysroot" \ RANLIB=aarch64-linux-android-ranlib AR=aarch64-linux-android-ar PATH=/usr/local/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin:/usr/bin:/bin \ PREFIX=/android/arm \ ./configure \ --target-os=android \ --arch=aarch64 \ --enable-cross-compile \ --cc=aarch64-linux-android21-clang \ --strip=aarch64-linux-android-strip \ --enable-decoder=hevc && \ CC="aarch64-linux-android21-clang --sysroot /usr/local/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/sysroot" \ RANLIB=aarch64-linux-android-ranlib AR=aarch64-linux-android-ar PATH=/usr/local/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin:/usr/bin:/bin \ make -j4 install prefix /usr/local source path .
