A lightweight ,high performance and stable stream server and client framework based on C++11.

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/HTTP-TS/WebSocket-TS/HTTP-fMP4/Websocket-fMP4/MP4),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.

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/xia-chu/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:

  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

• 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

• 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：

  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：

  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：

  //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：

  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");
  });
