Summary
This article describes how to compile and run ZLMediaKIt on Windows .
lab environment
操作系统：Windows 10 (22H2 19045.2251)
开发工具：Visual Studio 2022
background knowledge
Compiling ZLMediaKit on Windows is slightly more difficult than compiling ZLMediaKit on Ubuntu .
To experience the lowest latency WebRTC function of ZLMediaKit, you need to pre-compile the following open source libraries:
FFmpeg: 用于拉流、转码、编码、推流。
OpenSSL: 加密库、TLS库。
libsrtp：SRTP（安全实时传输协议），用于WebRTC音视频数据的安全传输。
usrsctp: 一个采用C语言开发的SCTP协议栈，用于WebRTC数据通道的安全传输。FFmpeg compilation
Method 1: Download the precompiled development package directly from the FFmpeg official website.
Method 2: Refer to "Compiling FFmpeg on Windows"
OpenSSL compilation
It is recommended to use vcpkg to install the OpenSSL 3.1.1 development package. The command is as follows:
vcpkg install openssl --triplet x64-windowsSet the environment variable CMAKE_TOOLCHAIN_FILE to the vcpkg.cmake file path. The example is as follows:
rem 请将环境变量值替换成你的vcpkg的实际安装路径。
环境变量名：CMAKE_TOOLCHAIN_FILE
环境变量值：G:\vcpkg\scripts\buildsystems\vcpkg.cmakelibsrtp compile
Run cmd.exe and perform the following operations in its command line interface:
#获取源码
git clone https://github.com/cisco/libsrtp.git
#进入libsrtp的源码仓库目录，用git命令查看标签，创建分支：
cd libsrtp
git tag
git checkout v2.5.0
#创建构建目录，用cmake构建。
mkdir build_x64
cd build_x64
cmake -S .. -B . -A x64 -DBUILD_SHARED_LIBS=on -DENABLE_OPENSSL=on
rem 如下命令会构建所有项目（project），包括测试项目。
cmake --build . --config Debug --target ALL_BUILD
rem 如果你只想构建srtp2项目，可以将上一行命令替换为如下命令：
cmake --build . --config Debug --target srtp2
#安装编译结果
#注意：将YOU_SRTP_INTALL_DIR替换为实际的安装目录。
cmake --install . --config Debug --prefix YOU_SRTP_INTALL_DIR
#修改PATH环境变量
#为了让cmake的find_package命令能找到已安装的librtcp开发包，
#请将libsrtp开发包的实际安装目录添加到PATH环境变量中。usrsctp compile
Find a source code warehouse to store the folder, run cmd.exe, and perform the following operations:
git clone https://github.com/sctplab/usrsctp.git
cd usrsctp
git tag
git checkout 0.9.5.0
mkdir build_x64
cd build_x64
rem 注意：用你本地工作路径替换“--install-prefix=”参数的值。
cmake -S .. -B . -A x64 --install-prefix=%YOUR_WORK_DIR%\usrsctp\output -Dsctp_werror=off
rem 用VS 2022打开生成的解决方案，修改usrsctp项目的Debug配置的运行库选项，
rem 改为与ZLMediaKit的MediaServer项目的配置一致，比如：/MTd。
rem 编译usrsctp项目和INSTALL项目。
rem 将output目录的全路径添加到PATH环境变量中，
rem 或者将安装包内容复制到任何cmake能查找到的目录。Get ZLMediaKit source code
ZLMediaKit officially recommends using git to clone the ZLMediaKit code. The example is as follows:
#国内用户推荐从同步镜像网站gitee下载
git clone --depth 1 https://gitee.com/xia-chu/ZLMediaKit
cd ZLMediaKit
#千万不要忘记执行这句命令
git submodule update --initConfigure and build a Visual Studio solution
Run the cmake-gui program, select the ZLMediaKit source code directory and output directory, click the Configure button first, and then click the Generate button. The example is as follows:
Compile and run ZLMediaKit
打开ZLMediaKit\release\windows\Debug\Debug目录下的config.ini，修改secret密钥。
打开上一节的生成目录（例如：build_x64），双击打开ZLMediaKit.sln解决方案。
将MediaServer设为启动项目，按F5自动编译和运行。Summarize
On Windows, compiling the dependent libraries of ZLMediaKit is relatively troublesome, and there are many compilation methods. It requires more hands-on practice and troubleshooting when encountering problems. Once you have prepared the dependency libraries of ZLMediaKit, you will have a relaxed feeling of "a new village has a bright future" when you use a powerful IDE such as Visual Studio 2022 to compile and debug the ZLMediaKit source code.
