webrtc c++ library for mediasoup with full sfu c++ demo

项目说明: 本项目是基于mediasoup v3 版本 webrtc m84版本 的sfu的js版本修改成的c++版本,支持和js版本一样的完整demo功能,但是本项目是直接把worker进程代码集成 到了demo可以直接代码级别的调用,支持VC2019,xcode,CLion的开发环境,可以直接断点调试workder代码 本项目支持所有跨平台系统 WIN,Linux,Mac,嵌入式arm等系统,国产麒麟系统,支持嵌入式系统编译,编译说明,编译脚本支持跨平台编译,支持 WIN,Linux,Mac,嵌入式arm等系统,国产麒麟系统

编译说明,编译脚本支持跨平台编译,支持 WIN,Linux,Mac,嵌入式arm等系统,国产麒麟系统 1、下载依赖库boost https://jaist.dl.sourceforge.net/project/boost/boost/1.74.0/boost_1_74_0.tar.gz 放入lib目录下,记住不需要解解压缩,编译脚本会自动解压 1)、默认mac下用的是clang编译,ubuntu用的是gcc编译,按照系统默认安装编译器就行,gcc版本至少支持c++11版本大于 >= gcc-6.1 3)、其他的都是通过deps目录的源码进行编译的,再没有其他依赖库

2、arm平台变量设置 如果是跨平台编译,下述脚本只在对应平台执行一次即可(编译后的include和lib都自动安装到了release目录下用主程序调用) 跨平台编译需要先执行 x64位平台需要操作,可以忽略

source ./setarmenv.sh

3、依赖库编译(只编译一次)

./builddeps.sh

4、编译主程序 ./build.sh

生成的执行文件生成在 release/bin 目录下

参考8描述拷贝配置文件

5、也可以生成xcode,用xcode开发环境编译调试 ./genxcode.sh

6、也可以用clion编译调试 注意有时候更新后clion会有残留信息导致无法编译成功,此时需要删除cmake_debug目录,然后通过file执行invalidate,重启clion,然后重新导入工程,编译就行了 直接打开项目源码目录即可

7、如果用vc2019编译执行 win下使用llvm编译 LLVM下载链接地址 https://github.com/llvm/llvm-project/releases/download/llvmorg-12.0.0/LLVM-12.0.0-win64.exe

visual studio使用clang https://blog.csdn.net/weixin_42707943/article/details/85119329?utm_medium=distribute.pc_relevant.none-task-blog-BlogCommendFromMachineLearnPai2-2.channel_param&depth_1-utm_source=distribute.pc_relevant.none-task-blog-BlogCommendFromMachineLearnPai2-2.channel_param 安装插件 llvm compile toolchain 插件 安装好后重启软件,项目属性常规工具集改成LLVM,一般到这就可以使用了

如果下载不了可以通过这个网址下载插件 https://marketplace.visualstudio.com/items?itemName=LLVMExtensions.llvm-toolchain

注意:只有正确安装了llvm后才能执行下面的操作,否则会有提示错误无法生成工程 .\genvs2019.bat 生成工程文件即可打开工程编译 然后拷贝 lib\win\x64\libssl-1_1-x64.dll lib\win\x64\libcrypto-1_1-x64.dll 到执行文件所在Debug目录下即可

8、配置文件拷贝的编译的执行文件所在目录 配置文件在源码根目录下 demo/config.json 拷贝到 xcode/debug 目录下 或是clion的cmakebuild目录下和执行文件同一个目录 vc2019 需要拷贝到对应的Debug目录下,和执行文件同一个目录 详细配置可以参考mediasoup官方demo的配置 配置文件里面的ip地址需要配置对应服务器的内网地址和外网地址 "ip" : "192.168.1.192",//内网网卡地址 "announcedIp" : "192.168.1.192"//公网地址

9、问题及解决 目前整个项目只有下面的调用是c+14标准,其他都是c++11标准,后续如果有嵌入开发标准需求可以改成c++11 const RtpCapabilities supportedRtpCapabilities =

使用cmake生成xcode的项目

cmake .. -G "Xcode"

结果报如下错误

-- The C compiler identification is unknown

-- The CXX compiler identification is unknown

CMake Error at CMakeLists.txt:2 (project):

 No CMAKE_C_COMPILER could be found.

CMake Error at CMakeLists.txt:2 (project):

 No CMAKE_CXX_COMPILER could be found.

后来使用如下命令解决

sudo xcode-select --switch /Applications/Xcode.app/ sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer 重试时记得清空build下的文件
