iOS OC使用FDK-AAC编译

环境:Mac 

FDK-AAC是用来编码和解码ACC格式音频文件的开源库.LAME则是MP3格式的.

FDK-AAC 编译成iOS需要的库的方法

1.下载FDK-AAC库:http://www.linuxfromscratch.org/blfs/view/svn/multimedia/fdk-aac.html

或者https://downloads.sourceforge.net/opencore-amr/fdk-aac-0.1.6.tar.gz.下载完成后将其放到桌面一个新建的文件夹fdk-aac下.命名为fdk-aac-0.1.6.

2.下载一个Github上的shell脚本文件地址:https://github.com/kewlbear/fdk-aac-build-script-for-iOS,将下载的build-fdk-aac.sh文件放到文件夹fdk-aac下.

3.终端执行:brew install automake libtool .

4.修改build-fdk-aac.sh 文件里:SOURCE="fdk-aac-0.1.6"和ARCHS="arm64 x86_64 i386 armv7 armv7s",打开文本编辑修改就行

5.终端cd 到文件夹fdk-aac,再执行./build-fdk-aac.sh就好了

6.再cd 到 fdk-aac-ios文件夹下的lib文件夹 执行:file libfdk-aac.a

出现:

libfdk-aac.a: Mach-O universal binary with 5 architectures: [i386:current ar archive] [arm64]

libfdk-aac.a (for architecture i386): current ar archive

libfdk-aac.a (for architecture armv7): current ar archive

libfdk-aac.a (for architecture armv7s): current ar archive

libfdk-aac.a (for architecture x86_64): current ar archive

libfdk-aac.a (for architecture arm64): current ar archive

就好了
