[编译
//webrtc编译 src目录下 git bash
依赖环境:python3.10 DirectX SDK Debugging Tools vs2019 c++各组件

根据项目需求对源码做出修改:
‪音频参数配置(aec回音消除)—src\media\engine\webrtc_voice_engine.cc
‪ Windows端d3d渲染—src\test\win\d3d_renderer.cc
reverb_decay混响因数调节—src\modules\audio_processing\aec3\residual_echo_estimator.cc

MTd:链接VC的运行时库(msvcrt.lib)采用静态库 MDd:不链接VC的运行时库(msvcrt.lib)采用动态库

WIN32/_WIN32 可以用来判断是否 Windows 系统(对于跨平台程序)，而 _WIN64 用来判断编译环境是x86还是x64

gn clean out/Default

双击打开out/Default/all.sln
加载完成之后，在vs2019中找到src/webrtc项目进行编译(也可尝试 ninja -C out/Default //-j 1)，这个过程比较漫长
编译完成后会在out/Default/obj/目录生成webrtc.lib文件

is_clang： 默认开启 | is_clang置为false后ninja报错
use_rtti 默认不开启 如果在代码中使用typeid将引起链接失败
use_custom_libcxx 默认libcxx的c++标准库,链接时会与vc++的libcxx冲突,使用use_custom_libcxx=false从而链接vs++版本
enable_iterator_debugging=true –VS默认debug版本会设置_ITERATOR_DEBUG_LEVEL=0，所以我们编译的时候也要打开这个宏，该宏最后会设置_ITERATOR_DEBUG_LEVEL=2
rtc_use_h264：用h264编解码
rtc_include_tests：关闭测试代码，如果开着，可能会报一些错误
rtc_build_ssl：是否编译BoringSSL
is_component_ffmpeg: 是否使用ffmpeg
ffmpeg_branding: ffmpeg的分支名，这里采用Chrome的分支

//libmediasoupclient cmake-gui编译出vs工程

cmake . -Bbuild -DLIBWEBRTC_INCLUDE_PATH:PATH=G:\libs\webrtc\webrtc\src -DLIBWEBRTC_BINARY_PATH:PATH=G:\libs\webrtc\webrtc\src\out\Default\obj

mediasoupclient依赖于sdptransform和ZERO_CHECK，所以首先编译生成ZERO_CHECK，再编译生成sdptransform
