快速开始

Windows SRTC 音视频 SDK 快速集成，10 分钟跑通基础功能

​

初始化SDK

SRTC::StatusCode ret = SRTC::RTCEngine_Init(&_irtc);
if((ret |= SRTC::StatusCode::OK) || !_irtc)
{
    return false;
}
```cpp



### 设置消息回调
```cpp
_irtc->setEventHandler(this);

加入频道

//如果需要修改配置信息请在,通过getSetting,进行参数设置
std::string token = "";
_irtc->joinChannel(token);
//触发 IRTCEngineEvent.onJoinRoom 事件之后才是真正的入会成功
```typescript

### 开关摄像头
```cpp
    SRTC::IRTCLocalCameraTrack* _camStream = nullptr;
    const char* track_key = "camera";
    SRTC::StatusCode ret = _irtc->getCameraTrack(track_key,&_camStream);
    if((ret != SRTC::StatusCode::OK) || !_camStream )
    {
        return ret;
    }
    _camStream->addPlayView(callbackView);
    _camStream->startCapture();
    _irtc->publish(_camStream);

    SRTC::IRTCLocalCameraTrack* _camStream = nullptr;
    const char* track_key = "camera";
    SRTC::StatusCode ret = _irtc->getCameraTrack(track_key,&_camStream);
    if((ret != SRTC::StatusCode::OK) || !_camStream )
    {
        retrun ret;
    }
    
    _camStream->stopCapture();
    _camStream->removeAllPlayView();
    _irtc->unpublish(_camStream);
```typescript

### 开关麦克风
```cpp
    SRTC::IRTCLocalMicTrack* _micStream = nullptr;
    const char* track_key = "mic";
    SRTC::StatusCode ret = _irtc->getAudioTrack(track_key,&_micStream);
    if((ret != SRTC::StatusCode::OK) || !_micStream )
    {
        return ret;
    }
    _micStream->startCapture();   
    _irtc->publish(_micStream); 

    SRTC::IRTCLocalMicTrack* _micStream = nullptr;
    const char* track_key = "mic";
    SRTC::StatusCode ret = _irtc->getAudioTrack(track_key,&_micStream);
    if((ret != SRTC::StatusCode::OK) || !_micStream )
    {
        return ret;
    }

    _micStream->stopCapture();
    _irtc->unpublish(_micStream); 
```typescript

### 开关桌面共享
```cpp
    SRTC::IRTCLocalScreenTrack* _screenStream = nullptr;
    const char* track_key = "screen";
    SRTC::StatusCode ret = _irtc->getScreenTrack(track_key,&_screenStream);
    if((ret != SRTC::StatusCode::OK) || !_screenStream )
    {
        return ret;
    }
    _screenStream->startCapture();
    _irtc->publish(_screenStream); 

    SRTC::IRTCLocalScreenTrack* _screenStream = nullptr;
    const char* track_key = "screen";
