FFMPEG libfdk-aac Windows上编译

1.源码下载
下载命令及地址：
git clone https://github.com/mstorsjo/fdk-aac.git



2.添加CMake使用的脚本
在fdk-aac的源码路径下创建CMakeList.txt，然后写入以下脚本命令：# source code: git clone https://android.googlesource.com/platform/external/aac cmake_minimum_required ( VERSION 2.8 )

if (CMAKE_SYSTEM_NAME STREQUAL Android )
if ( NOT CMAKE_SYSTEM_PROCESSOR )
set ( CMAKE_SYSTEM_PROCESSOR armeabi-v7a )
endif ()
if ( NOT CMAKE_SYSTEM_VERSION )
set ( CMAKE_SYSTEM_VERSION 8 )
endif ()
if ( NOT NDK_TOOLCHAIN_VERSION)
set ( NDK_TOOLCHAIN_VERSION 4.8 )
endif ()

set ( ANDROID_NDK_ROOT $ENV{ANDROID_NDK_ROOT} )

find_path ( TOOLCHAIN_ROOT bin PATHS ${ANDROID_NDK_ROOT}/toolchains/arm-linux-androideabi-${NDK_TOOLCHAIN_VERSION}/prebuilt/* )

include ( CMakeForceCompiler )

find_program ( CMAKE_C_COMPILER arm-linux-androideabi-gcc PATHS ${TOOLCHAIN_ROOT}/bin )
find_program ( CMAKE_CXX_COMPILER arm-linux-androideabi-g++ PATHS ${TOOLCHAIN_ROOT}/bin )
find_program ( CMAKE_AR arm-linux-androideabi-ar PATHS ${TOOLCHAIN_ROOT}/bin )

cmake_force_c_compiler ( ${CMAKE_C_COMPILER} GNU )
cmake_force_cxx_compiler ( ${CMAKE_CXX_COMPILER} GNU )

set ( CMAKE_SYSROOT ${ANDROID_NDK_ROOT}/platforms/android-${CMAKE_SYSTEM_VERSION}/arch-arm CACHE PATH "" )

set( CMAKE_FIND_ROOT_PATH_MODE_PROGRAM ONLY )
set( CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY )
set( CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY )

endif ()

project ( fdk-aac )

if ( NOT INCLUDE_INSTALL_DIR )
set ( INCLUDE_INSTALL_DIR include )
endif ()

if ( NOT ARCHIVE_INSTALL_DIR )
set ( ARCHIVE_INSTALL_DIR lib/static )
endif ()

if ( NOT IS_DIRECTORY ${FDK_AAC_SOURCE_DIR} )
message ( FATAL_ERROR "FDK_AAC_SOURCE_DIR=${FDK_AAC_SOURCE_DIR} is not a dir" )
endif ()

if ( CMAKE_SYSTEM_NAME STREQUAL Android )
add_definitions (
--sysroot=${CMAKE_SYSROOT}
-fPIC
-march=armv7-a
-mfpu=vfpv3-d16
-DANDROID
-mhard-float
-D_NDK_MATH_NO_SOFTFP=1
-lm_hard )
endif ()

add_definitions (
-fno-rtti
-fno-exceptions )

set ( SOURCE_FILES )

foreach ( subdir
libAACdec libAACenc libFDK
libMpegTPDec libMpegTPEnc
libPCMutils
libSBRdec libSBRenc
libSYS )

set ( __inc_dir ${FDK_AAC_SOURCE_DIR}/${subdir}/include )

include_directories ( ${__inc_dir} )
install ( DIRECTORY ${__inc_dir}/ DESTINATION ${INCLUDE_INSTALL_DIR}/fdk-aac/ )

file ( GLOB __src_files
${FDK_AAC_SOURCE_DIR}/${subdir}/src/*.cpp
${FDK_AAC_SOURCE_DIR}/${subdir}/src/*.h )
list ( APPEND SOURCE_FILES ${__src_files} )
endforeach ()

add_library ( fdk-aac STATIC
${SOURCE_FILES} )

install ( TARGETS fdk-aac
ARCHIVE DESTINATION ${ARCHIVE_INSTALL_DIR} )
 
3.VS工程建立
运行CMake(GUI)工具，如图处理：
 



 
4.工程创建成功后，进行编译。
5.编译好的libfdk-aac,放入到ffmpeg目录下进行编译。
./configure --enable-shared --disable-static --enable-optimizations --enable-protocols --enable-gpl --enable-version3--enable-libx264 --enable-encoder=libx264 --enable-libfdk-aac --enable-nonfree  --enable-decoder=h264 --enable-encoder=h264 --enable-encoder=aac --enable-decoder=aac --enable-encoder=pcm --enable-decoder=pcm  --disable-programs --prefix=./vs2015_shared --toolchain=msvc --disable-debug --extra-cflags=-I/usr/local/include --extra-ldflags=-LIBPATH:/usr/local/lib
