# 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)


## Why ZLMediaKit?
- 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.
- Support rich streaming media protocols(`RTSP/RTMP/HLS/HTTP-FLV/Websocket-flv`),and support Inter-protocol conversion.
- Multiplexing asynchronous network IO based on epoll and multi thread，extreme performance.
- Well performance and stable test,can be used commercially.
- Support linux, macos, ios, android, Windows Platforms.
- Very low latency(lower then one second), video opened immediately.

## System Requirements

- 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.

## 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.

### Before build
- **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.You can do it like this:**
```
git clone https://github.com/zlmediakit/ZLMediaKit.git
cd ZLMediaKit
git submodule update --init
```

### Build on linux

- My environment
  - Ubuntu16.04 64 bit and gcc5.4
  - cmake 3.5.1
- Guidance
  
  ```
	# If it is on centos6.x, you need to install the newer version of GCC and cmake first, 
	# 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、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 devtoolset-4-toolchain -y
	scl enable devtoolset-4 bash
	
	# 2、Install cmake (this step can be skipped if the cmake version is higher than 3.1)
	tar -xvf cmake-3.10.0-rc4.tar.gz #you need download cmake source file manually
	cd cmake-3.10.0-rc4
	./configure
	make -j4
	sudo make install
	
	# 3、Switch to high version GCC
	scl enable devtoolset-4 bash
	
	# 4、build
	cd ZLMediaKit
	./build_for_linux.sh
  ```

### Build on macOS

- My environment
  - macOS Sierra(10.12.1) + xcode8.3.1
  - Homebrew 1.1.3
  - cmake 3.8.0
- Guidance
  
  ```
  cd ZLMediaKit
  ./build_for_mac.sh
  ```

### Build on iOS
- You can generate Xcode projects and recompile them , [learn more](https://github.com/leetal/ios-cmake):

  ```
  cd ZLMediaKit
  mkdir -p build
  cd build
  # Generate Xcode project, project file is in build directory
  cmake .. -G Xcode -DCMAKE_TOOLCHAIN_FILE=../cmake/ios.toolchain.cmake  -DPLATFORM=OS64COMBINED
  ```
  



### Build on Android

  Now you can open android sudio project in `Android` folder,this is a `aar library` and damo project.

- My environment
  - macOS Sierra(10.12.1) + xcode8.3.1
  - Homebrew 1.1.3
  - cmake 3.8.0
  - [android-ndk-r14b](https://dl.google.com/android/repository/android-ndk-r14b-darwin-x86_64.zip)
- Guidance 

  ```
  cd ZLMediaKit
  export ANDROID_NDK_ROOT=/path/to/ndk
  ./build_for_android.sh
  ```
### Build on Windows

- My environment
  - windows 10
  - visual studio 2017
  - [cmake-gui](https://cmake.org/files/v3.10/cmake-3.10.0-rc1-win32-x86.msi)
  
- Guidance
```
1 Enter the ZLMediaKit directory and execute git submodule update -- init downloads the code for ZLToolKit
2 Open the project with cmake-gui and generate the vs project file.
3 Find the project file (ZLMediaKit.sln), double-click to open it with vs2017.
4 Choose to compile Release version. Find the target file and run the test case.
```
## Usage

- As server：
	```cpp
	TcpServer::Ptr rtspSrv(new TcpServer());
	TcpServer::Ptr rtmpSrv(new TcpServer());
	TcpServer::Ptr httpSrv(new TcpServer());
	TcpServer::Ptr httpsSrv(new TcpServer());
	
	rtspSrv->start<RtspSession>(mINI::Instance()[Config::Rtsp::kPort]);
	rtmpSrv->start<RtmpSession>(mINI::Instance()[Config::Rtmp::kPort]);
	httpSrv->start<HttpSession>(mINI::Instance()[Config::Http::kPort]);
	httpsSrv->start<HttpsSession>(mINI::Instance()[Config::Http::kSSLPort]);
	```

- As player：
	```cpp
    MediaPlayer::Ptr player(new MediaPlayer());
    weak_ptr<MediaPlayer> weakPlayer = player;
    player->setOnPlayResult([weakPlayer](const SockException &ex) {
        InfoL << "OnPlayResult:" << ex.what();
        auto strongPlayer = weakPlayer.lock();
        if (ex || !strongPlayer) {
            return;
        }

        auto viedoTrack = strongPlayer->getTrack(TrackVideo);
        if (!viedoTrack) {
            WarnL << "none video Track!";
            return;
        }
        viedoTrack->addDelegate(std::make_shared<FrameWriterInterfaceHelper>([](const Frame::Ptr &frame) {
            //please decode video here
        }));
    });

    player->setOnShutdown([](const SockException &ex) {
        ErrorL << "OnShutdown:" << ex.what();
    });

    //rtp transport over tcp
    (*player)[Client::kRtpType] = Rtsp::RTP_TCP;
    player->play("rtsp://admin:jzan123456@192.168.0.122/");
	```
- As proxy server：
	```cpp
	//support rtmp and rtsp url
	//just support H264+AAC
	auto urlList = {"rtmp://live.hkstv.hk.lxdns.com/live/hks",
			"rtsp://184.72.239.149/vod/mp4://BigBuckBunny_175k.mov"};
	map<string , PlayerProxy::Ptr> proxyMap;
	int i=0;
	for(auto url : urlList){
		PlayerProxy::Ptr player(new PlayerProxy("live",to_string(i++).data()));
		player->play(url);
		proxyMap.emplace(string(url),player);
	}
	```
	
- As puser：
	```cpp
	PlayerProxy::Ptr player(new PlayerProxy("app","stream"));
	player->play("rtmp://live.hkstv.hk.lxdns.com/live/hks");
	
	RtmpPusher::Ptr pusher;
	NoticeCenter::Instance().addListener(nullptr,Config::Broadcast::kBroadcastRtmpSrcRegisted,
			[&pusher](BroadcastRtmpSrcRegistedArgs){
		const_cast<RtmpPusher::Ptr &>(pusher).reset(new RtmpPusher(app,stream));
		pusher->publish("rtmp://jizan.iok.la/live/test");
	});
	
	```
## Docker Image
You can pull a pre-built docker image from Docker Hub and run with
