 1 | # fdk-aac build script for iOS
 2 | 
 3 | See https://github.com/kewlbear/FFmpeg-iOS for .xcframework support, integration with FFmpeg and more.
 4 | 
 5 | Shell script to build fdk-aac for use in iOS apps.
 6 | 
 7 | ## Preparation
 8 | 
 9 | ```
10 | brew install automake libtool
11 | fdk-aac-X.X.X/autogen.sh
12 | ```
13 | 
14 | ## Usage
15 | 
16 | * Build all:
17 | 
18 | ```
19 | build-fdk-aac.sh
20 | ```
21 | 
22 | * Build for some architectures:
23 | 
24 | ```
25 | build-fdk-aac.sh armv7s x86_64
26 | ```
27 | 
28 | * Build universal library from separately built architectures:
29 | 
30 | ```
31 | build-fdk-aac.sh lipo
32 | ```
33 |
