FFmpeg iOS build script

测试环境:

FFmpeg 4.4.1
Xcode 13.1 (13A1030d)
MacOS 11.6.1 (20G221)

注意事项

4.4目前无法编译Audiotoolbox，代码中也有写。建议编译4.3.2即可

编译依赖

https://github.com/libav/gas-preprocessor
yasm 1.2.0

使用方法

设定FFMpeg架构

# i386 抛弃吧
# armv7 也抛弃吧
# x86_64 Intel专用 M1模拟器也是ARM64的
# arm64

# 选择编译架构
ARCHS="x86_64 arm64"
# 最低支持版本 2021年了建议iOS11起
DEPLOYMENT_TARGET="8.0"

设定编译FFMpeg版本

# 编译FFmpeg版本
FFMPEG_VERSION="4.4.1"

进入到当前目录直接执行脚本即可，如遇无法执行，可能是文件权限问题

cd ios-ffmpeg-build-script-ilongge
./build-ffmpeg.sh

使用依赖

VideotoolBox
Audiotoolbox
libz.dylib
libbz2.dylib
libiconv.dylib
