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());

}

ContinuousMove_REQ req;

memset(&req, 0, sizeof(req));

#ifdef Simple_ONVIF_SPEED

float onvif_speed = 0.0;

if ((speed > 100) || (speed < 0))

{

printf("==%s==Line:%d >> Speed=%d,out of the range\n", __FUNCTION__, __LINE__, speed);

return false;

}

onvif_speed = float(speed / 100.0);

#endif

switch (command)

{

#else

req.Velocity.PanTilt.x = -1;

#endif // Simple_ONVIF_SPEED

req.Velocity.PanTilt.y = 0;

break;

case Simple_PTZ_CMD_TYPE_RIGHT:

req.Velocity.PanTiltFlag = 1;

#ifdef Simple_ONVIF_SPEED

req.Velocity.PanTilt.x = onvif_speed;

#else

req.Velocity.PanTilt.x = 1;

#endif

req.Velocity.PanTilt.y = 0;

break;

case Simple_PTZ_CMD_TYPE_UP:

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_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;

#ifdef Simple_ONVIF_SPEED

req.Velocity.Zoom.x = -(onvif_speed);

#else

req.Velocity.Zoom.x = -1;

#endif

break;

case Simple_PTZ_CMD_TYPE_ZOOMOUT:

req.Velocity.ZoomFlag = 1;

#ifdef Simple_ONVIF_SPEED

req.Velocity.Zoom.x = onvif_speed;

#else

req.Velocity.Zoom.x = 1;

#endif

break;
