02 安装xcode
xcode需要在苹果商店现在，需要有个一苹果商店的账号(Apple ID).这个账号可以免费注册。
在点击苹果商店，在搜索栏搜索xcode，点击获取/安装，开始下载，可看到下载进度。下载完成，会自动安装。
下载完成后，安装
安装完成后，记得输入切换指令
sudo xcode-select --switch /Applications/Xcode.app/
03 安装必要软件
安装git wget cmake make FFmpeg x264
brew install git wget cmake make FFmpeg x264
brew install qt
安装好qt后，根据提示配置qt path路径
echo 'export PATH="/usr/local/opt/qt/bin:$PATH"' >> ~/.bash_profile
softdeMac:obs-studio soft$ source ~/.bash_profile
安装cmake-gui
cmake-gui 安装，从cmake.org下载安装mac版本
下载最新链接 https://cmake.org/files/v3.13/cmake-3.13.0-rc1-Darwin-x86_64.dmg
04 下载obs-studio代码
mkdir git
cd git
git clone --recursive https://github.com/obsproject/obs-studio.git
cd obs-studio
05 编译obs-studio 22.0.3
05.01 切换稳定版本 22.0.3
cd obs-studio
git checkout -b b22.03. 22.03
05.02 配置cmake-gui
配置路径，设置
QTDIR=/usr/local/opt/qt/
,这个路径安装好qt是有提示的。
点击配置
配置编译工具
设置CMAKE_INSTALL_PREFIX,打开xcode
CMAKE_INSTALL_PREFIX=/Users/soft/git/obs-studio/build/mac64/install
05.03 编译obs-studio 22.0.3
设置 Scheme 的工作路径
Use custom working directory=/Users/soft/git/obs-studio/build/mac64/rundir/Debug/bin
05.04 运行调试
06 obs-studio 完整配置
05 只是最小可运行环境。根据cmake-gui的提示，可以看到，还需要很多依赖包，说着说obs-studio还支持很多扩展。比如:
softdeMac:~ soft$ brew install MbedTls lua python swig speexdsp luajit freetype dbus

browser是指基础了cef，需要单独下载。
Sparkle也需要单独下载。
cef 比较特殊，制作安装包时需要单独处理。本实验先不包含cef。
Sparkle下载地址:
https://github.com/sparkle-project/Sparkle/releases/download/1.20.0/Sparkle-1.20.0.tar.bz2
加压后到~/Sparkle-1.20.0/
编译运行./obs
提示:
[softdeMac:bin soft$ ./obs
dyld: Library not loaded: @rpath/Sparkle.framework/Versions/A/Sparkle
Referenced from: /Users/soft/git/obs-studio/build/mac64/rundir/Release/bin/./obs
Reason: image not found
Abort trap: 6
这是说明需要把Sparkle依赖拷贝到obs目录下。
我们只要把依赖拷贝到obs-studio源码下面的additional_install_files目录的应用版本下即可。
根据不同macOS的版本和Debug/Release版本。
32位系统对应exec32/exec32d/exec32r。
64位系统对应exec64/exec64d/exec64r。
exec64对应Release版本。
exec64d对应Debug版本。
把需要的依赖拷贝到对应的execXX目录即可。
cd ~/git/obs-studio/additional_install_files/exec64/
# cd ~/git/obs-studio/additional_install_files/exec64d/
# cd ~/git/obs-studio/additional_install_files/exec64r/

# 需要特别注意，当勾选Sparkle时，可能会引起调试异常
cp -r ~/Sparkle-1.20.0/Sparkle.framework ./
主要项目作用：
设置工作目录
设置工作路
/~/git/obs-studio/build/mac64/rundir/Debug/bin/
07 注意事项
07.01 勾选Sparkle项目时，可能引起xcode调试异常
不影响实际运行
./obs
方式运行，和打包后正常运行。仅仅调试时异常。
07.02 package项目调整
默认打包不能再非开发环境使用
直接通过package项目生成的dmg包。不能在非开发环境运行。
1 依赖包不全
2 动态库的引用路径需要进行处理。
需要参考如下文件:
cmake/osxbundle/fixup_bundle.sh
cmake/osxbundle/Info.plist
cmake/osxbundle/obs.icns
cmake/osxbundle/obslaunch.sh
cmake/Modules/ObsHelpers.cmake
另外也可以参考
CI
目录下面和mac相关的脚本。
A:查找依赖
查找依赖的方法，主要是制作安装包，在非开发环境运行:
./obs
根据提示，逐个查找依赖，拷贝到对应的目录。
~/git/obs-studio/additional_install_files/exec64/
~/git/obs-studio/additional_install_files/exec64d/
~/git/obs-studio/additional_install_files/exec64r/
B:修改相对路径@rpath
主要方法是使用
otool
查看相对路径，使用
install_name_tool
修改二进制和动态库的引用路径。
根据如下两个文件，可知，只要调用了fixup_bundle.sh。即可解决相对路径问题。
cmake/Modules/ObsHelpers.cmake
cmake/osxbundle/fixup_bundle.sh
修改ObsHelpers.cmake代码：
install(CODE
"if(DEFINED ENV{FIXUP_BUNDLE})
execute_process(COMMAND \"${CMAKE_SOURCE_DIR}/cmake/osxbundle/fixup_bundle.sh\" . bin WORKING_DIRECTORY \"\${CMAKE_INSTALL_PREFIX}\")
endif()")
改为
install(CODE
"
execute_process(COMMAND \"${CMAKE_SOURCE_DIR}/cmake/osxbundle/fixup_bundle.sh\" . bin WORKING_DIRECTORY \"\${CMAKE_INSTALL_PREFIX}\")
")
并且cmake-gui中 不勾选
USE_LIBC++
选项。
07.03 取消安装包中的cmake/include目录
默认install目录包含cmake和include目录。我们制作dmg安装包时，时不需要这两个目录的。
在cmake 中去掉对应的install语句即可。
