## 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/xiongziliang/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");
});
```
