Using the CMake NDK to compile FDK-AAC in a Windows environment

One, nonsense

In recent studies, the first step is to compile. We need to compile FFMPAG,X264,FDK_AAC, below is x264, many of the online said are hundreds of years ago, I am the perfect available

Still , I am limited in my ability, but I hope that what I have written will make it more acceptable to more people. I was just in touch. Make a record and hope to be good for other people .
Contact me can directly comment, also can add me qq:11635423

second, dry goods

Preparation: 1.fdk_aac source git clone https://android.googlesource.com/platform/external/aac

3. need to download cmake directly inside the cmd can be, before the FFmpeg and x264 are Cygwin inside. Not now. You need to set the CMAKE environment variable to add to the path

4. Compile the script. This script is understood by itself. Me too smattering--script name:CMakeLists.txt

Third, compile

This compilation is relatively simple, as long as the download cmake. Direct CMake on it.

1. Navigate to the compiled directory

2. Execute cmake command
Cmake-g "MinGW makefiles" -dcmake_system_name=andr
oid-dfdk_aac_source_dir="e:/soft/source/fdk_aac/aac" E:\qupai_code_eclipse\code
\thirdparty\build\fdk-aac-dcmake_make_program=e:\android-ndk-r9c\prebuilt\windo
ws\bin\make. exe

3. CMake--bulid.---J8

Note:dfdk_aac_source_dir= "Your FDK_AAC's source address"

E:\qupai_code_eclipse\code\THIRDPARTY\BUILD\FDK-AAC----This is your CMakeLists.txt . Address
