# 一个基于C++11的高性能运营级流媒体服务框架 #A lightweight ,high performance and stable stream server and client framework based on C++11.
[![Build Status](https://travis-ci.org/xiongziliang/ZLMediaKit.svg?branch=master)](https://travis-ci.org/xiongziliang/ZLMediaKit) [![Build Status](https://travis-ci.org/xiongziliang/ZLMediaKit.svg?branch=master)](https://travis-ci.org/xiongziliang/ZLMediaKit)
## 项目特点 [中文](https://github.com/xiongziliang/ZLMediaKit/blob/master/README_CN.md)
- 基于C++11开发，避免使用裸指针，代码稳定可靠；同时跨平台移植简单方便，代码清晰简洁。
- 打包多种流媒体协议(RTSP/RTMP/HLS），支持协议间的互相转换，提供一站式的服务。
- 使用epoll+线程池+异步网络IO模式开发，并发性能优越。
- 已实现主流的的H264/H265+AAC流媒体方案，代码精简,脉络清晰，适合学习。
- 编码格式与框架代码解耦，方便自由简洁的添加支持其他编码格式
- 代码经过大量的稳定性、性能测试，可满足商用服务器项目。
- 支持linux、macos、ios、android、windows平台
- 支持画面秒开(GOP缓存)、极低延时(1秒内)
- [ZLMediaKit高并发实现原理](https://github.com/xiongziliang/ZLMediaKit/wiki/ZLMediaKit%E9%AB%98%E5%B9%B6%E5%8F%91%E5%AE%9E%E7%8E%B0%E5%8E%9F%E7%90%86)
## 项目定位 ## Why ZLMediaKit?
- 移动嵌入式跨平台流媒体解决方案。 - Developed based on C++ 11, the code is stable and reliable, avoiding the use of raw pointers, cross-platform porting is simple and convenient, and the code is clear and concise.
- 商用级流媒体服务器。 - Support rich streaming media protocols(`RTSP/RTMP/HLS/HTTP-FLV`),and support Inter-protocol conversion.
- 网络编程二次开发SDK。 - Multiplexing asynchronous network IO based on epoll and multi thread，extreme performance.
- Well performance and stable test,can be used commercially.

## 编译要求
- 编译器支持C++11，GCC4.8/Clang3.3/VC2015或以上
- cmake3.2或以上
- **必须使用git下载完整的代码，不要使用下载zip包的方式下载源码，否则子模块代码默认不下载！**
## 编译(Linux) ## System Requirements
- 我的编译环境
- Ubuntu16.04 64 bit + gcc5.4 - Compiler support c++11，GCC4.8/Clang3.3/VC2015 or above.
- cmake3.1 or above.
- All Linux , both 32 and 64 bits
- Apple OSX(Darwin), both 32 and 64bits.
- All hardware with x86/x86_64/arm/mips cpu.
- Windows.
- **You must use git to clone the complete code. Do not download the source code by downloading zip package. Otherwise, the sub-module code will not be downloaded by default.**
## How to build
It is recommended to compile on Ubuntu or MacOS，compiling on windows is cumbersome, and some features are not compiled by default.
### Build on linux
- My environment
- Ubuntu16.04 64 bit and gcc5.4
- cmake 3.5.1 - cmake 3.5.1
- 编译 - Guidance
``` ```
//如果是centos6.x,需要先安装较新版本的gcc以及cmake，然后打开脚本build_for_linux.sh手动编译 # If it is on centos6.x, you need to install the newer version of GCC and cmake first,
//如果是ubuntu这样的比较新的系统版本可以直接操作第4步 # and then compile manually according to the script "build_for_linux.sh".
# If it is on a newer version of a system such as Ubuntu or Debain,
# step 4 can be manipulated directly.
1、安装GCC5.2(如果gcc版本高于4.7可以跳过此步骤) # 1、Install GCC5.2 (this step can be skipped if the GCC version is higher than 4.7)
sudo yum install centos-release-scl -y sudo yum install centos-release-scl -y
sudo yum install devtoolset-4-toolchain -y sudo yum install devtoolset-4-toolchain -y
scl enable devtoolset-4 bash scl enable devtoolset-4 bash
2、安装cmake # 2、Install cmake (this step can be skipped if the cmake version is higher than 3.1)
#需要安装新版本cmake,当然你也可以通过yum或者apt-get方式安装(前提是版本够新) tar -xvf cmake-3.10.0-rc4.tar.gz #you need download cmake source file manually
tar -xvf cmake-3.10.0-rc4.tar.gz
cd cmake-3.10.0-rc4 cd cmake-3.10.0-rc4
./configure ./configure
make -j4 make -j4
sudo make install sudo make install
3、切换高版本gcc # 3、Switch to high version GCC
scl enable devtoolset-4 bash scl enable devtoolset-4 bash
4、编译 # 4、build
cd ZLMediaKit cd ZLMediaKit
./build_for_linux.sh ./build_for_linux.sh
``` ```
## 编译(macOS) ###Build on macOS

``` ```
cd ZLMediaKit cd ZLMediaKit
mkdir -p build mkdir -p build
cd build cd build
# 生成Xcode工程，工程文件在build目录下 # Generate Xcode project, project file is in build directory
cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/iOS.cmake -DIOS_PLATFORM=SIMULATOR64 -G "Xcode" cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/iOS.cmake -DIOS_PLATFORM=SIMULATOR64 -G "Xcode"
``` ```

  3 找到工程文件(ZLMediaKit.sln),双击用vs2017打开. 3 Find the project file (ZLMediaKit.sln), double-click to open it with vs2017.
  4 选择编译Release 版本. 4 Choose to compile Release version. Find the target file and run the test case.
5 找到目标文件并运行测试用例.

## QA
- 怎么测试服务器性能？
ZLMediaKit提供了测试性能的示例，代码在tests/test_benchmark.cpp。 ## Mirrors
这里是测试报告：[benchmark.md](https://github.com/xiongziliang/ZLMediaKit/blob/master/benchmark.md) [ZLToolKit](http://git.oschina.net/xiahcu/ZLToolKit)
- github下载太慢了，有其他下载方式吗？ [ZLMediaKit](http://git.oschina.net/xiahcu/ZLMediaKit)
你可以在通过开源中国获取最新的代码，地址为：
[ZLToolKit](http://git.oschina.net/xiahcu/ZLToolKit)
[ZLMediaKit](http://git.oschina.net/xiahcu/ZLMediaKit)
- 在windows下编译很多错误？
由于本项目主体代码在macOS/linux下开发，部分源码采用的是无bom头的UTF-8编码；由于windows对于utf-8支持不甚友好，所以如果发现编译错误请先尝试添 加bom头再编译。
也可以通过参考这篇博客解决:
[vs2015:/utf-8选项解决UTF-8 without BOM 源码中文输出乱码问题](https://blog.csdn.net/10km/article/details/80203286)
