Download of fdk-aac-2.0.1.tar.gz:

https://sourceforge.net/projects/opencore-amr/files/fdk-aac/

uzip & configure:

tar -zxvf fdk-aac-2.0.1.tar.gz
# create build folder 
mkdir build 
cd build
# check the path of the destination folder
pwd 
cd ..
# for example mips architecture,
./configure --enable-static --host=mips-linux CC=rsdk-linux-gcc CXX=rsdk-linux-g++ --prefix=(your build fdk_aac path)

compile:

make -j8

install:

make install

Build library encapsulates PCM to AAC

copy resource:

cp -r (your build fdk_aac path)/lib/* ./libs/fdk-aac-mips-2.0.1/lib
cp -r (your build fdk_aac path)/inclue/* ./libs/fdk-aac-mips-2.0.1/inclue

edit Makefile.sdk.conf :

ARCH_MIPS =1
#OR
# ARCH_ARM =1

Compile lib:

make clean 
make lib

Example :

unsigned int outputBuffer[4096] = {0};
int outputSize = 0;

if (aacEncInit(16000,16,1))
{
    printf("aac init fail \n");
}

while(1)
{
    outputSize = aacEncode(buffer->vm_addr, buffer->bytesused, outputBuffer);
}

aacEncEnd();
