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);

//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

    {
        return ret;
    }
    _camStream->addPlayView(callbackView);
    _camStream->startCapture();
    _irtc->publish(_camStream);

    SRTC::IRTCLocalCameraTrack* _camStream = nullptr;
