1.SimpleOnvif的功能
提供支持Windows、Linux、arm、Android、iOS等各种平台的SDK库，方便集成，二次开发。
2.onvif的搜索实现
std::map<std::string, std::string> OnvifService::GetDiscoveryDevices()
{
std::map<std::string, std::string> devs;
SimpleMutex lock(&mutex_);
std::map<std::string, ONVIF_DEVICE*>::iterator it = OnvifDeviceMap_.begin();
while (it != OnvifDeviceMap_.end())
{
ONVIF_DEVICE* dev = it->second;
char url[256] = {0};
snprintf(url, 255, "%s://%s:%d%s", dev->binfo.XAddr.https ? "https" : "http", dev->binfo.XAddr.host, dev->binfo.XAddr.port, dev->binfo.XAddr.url);
devs.insert(std::make_pair(dev->binfo.XAddr.host, url));
it++;
}
return devs;
}
3.onvif ptz实现
bool OnvifService::StartPtz(SimplePTZCMDType command, unsigned int speed, const std::string& host, const std::string& username, const std::string& password, const std::string& deviceUrl)
{
ONVIF_DEVICE manualDevice;
ONVIF_DEVICE* device = getDevice(&manualDevice, host, username, password, deviceUrl);
BOOL ret = false;
if (!device)
{
printf("==%s==Line:%d >> Get device Fail continue to find Device!!!\n", __FUNCTION__,__LINE__);
//return false;
}
else
{
onvif_SetAuthInfo(device, username.c_str(), password.c_str());
}

memset(&req, 0, sizeof(req));
#ifdef Simple_ONVIF_SPEED

#else

#endif
break;
case Simple_PTZ_CMD_TYPE_DOWN:
req.Velocity.PanTiltFlag = 1;
req.Velocity.PanTilt.x = 0;
#ifdef Simple_ONVIF_SPEED
req.Velocity.PanTilt.y = -(onvif_speed);
#else
req.Velocity.PanTilt.y = -1;
#endif
break;
case Simple_PTZ_CMD_TYPE_ZOOMIN:
req.Velocity.ZoomFlag = 1;
