SmartLib - A Onvif Library

---

SmartLib is useful for discovery IP cameras within networks which supports ONVIF and UPNP protocols.We can also add camera which supports these protocols.

Features

• ONVIF & UPnP discovery
• ONVIF device management (Services, device information, media profiles, raw media stream uri)
• UPnP device information
• Easily extendable with your custom requests

Discovery

---

The OnvifDiscovery class uses the Web Services Dynamic Discovery (WS-Discovery). This is a technical specification that defines a multicast discovery protocol to locate services on a local network. It operates over TCP and UDP port 3702 and uses IP multicast address 239.255.255.250. As the name suggests, the actual communication between nodes is done using web services standards, notably SOAP-over-UDP.

With WS-Discovery, the discovery tool puts SSDP queries on the network from its unicast address to 239.255.255.250 multicast address, sending them to the well-known UDP port 3702. The device receives the query, and answers to the discovery tool's unicast IP address from its unicast IP address. The reply contains information about the Web Services (WS) available on the device.

UPnP works in a very similar way, but on a different UDP port (1900). Compared to the WS-Discovery, the UPnP is intended for a general use (data sharing, communication, entertainment).

DiscoveryManager manager = new DiscoveryManager();
manager.setDiscoveryTimeout(10000);
manager.discover(new DiscoveryListener() {
    @Override
    public void onDiscoveryStarted() {
        System.out.println("Discovery started");
    }

    @Override
    public void onDevicesFound(List<Device> devices) {
        for (Device device : devices)
            System.out.println("Devices found: " + device.getHostName());
    }
});

ONVIF

---

With the OnvifManager class it is possible to send requests to an ONVIF-supported device. All requests are sent asynchronously and you can use the OnvifResponseListener for errors and custom response handling. It is possible to create your own OnvifDevice or retrieve a list from the discover method in the DiscoveryManager

onvifManager = new OnvifManager();
onvifManager.setOnvifResponseListener(this);
OnvifDevice device = new OnvifDevice("192.168.0.4:36000", "admin", "admin");

Services

Returns information about services on the device.

onvifManager.getServices(device, new OnvifServicesListener() {
    @Override
    public void onServicesReceived(@Nonnull OnvifDevice onvifDevice, OnvifServices services) {
        
    }
});

Device information

Returns basic device information from the device. This includes the manufacturer, serial number, hardwareId, ...

onvifManager.getDeviceInformation(device, new OnvifDeviceInformationListener() {
    @Override
    public void onDeviceInformationReceived(@Nonnull OnvifDevice device, 
                                            @Nonnull OnvifDeviceInformation deviceInformation) {
        
    }
});

Media Profiles

Returns pre-configured or dynamically configured profiles. This command lists all configured profiles in a device. The client does not need to know the media profile in order to use the command.

onvifManager.getMediaProfiles(device, new OnvifMediaProfilesListener() {
    @Override
    public void onMediaProfilesReceived(@Nonnull OnvifDevice device, 
                                        @Nonnull List<OnvifMediaProfile> mediaProfiles) {
        
    }
});

Media Stream URI

Returns a raw media stream URI that remains valid indefinitely even if the profile is changed.

onvifManager.getMediaStreamURI(device, mediaProfiles.get(0), new OnvifMediaStreamURIListener() {
    @Override
    public void onMediaStreamURIReceived(@Nonnull OnvifDevice device, 
                                        @Nonnull OnvifMediaProfile profile, @Nonnull String uri) {
        
    }
});

PTZ

Send request for Pan,Tilt and Zoom.This provides rotating IP Camera to its Left,Right,Up and Down.also provides support for ZoomIn and ZoomOut.You have to provide PTZ Type like LEFT_MOVE,RIGHT_MOVE,UP_MOVE,DOWN_MOVE for rotating respectively.also ZOOM_IN and ZOOM_OUT for zooming.

onvifManager.sendPTZRequest(device, mediaProfile, PTZType.LEFT_MOVE, new OnvifPTZListener() {
                                           @Override
                                           public void onPTZReceived((@Nonnull OnvifDevice onvifDevice, boolean status) {
                                             //return PTZ status
    
    }
});

Stop PTZ

You can use stopPTZRequest for stopping rotation and zooming.

//for Stopping Pan,Tilt and Zoom
onvifManager.stopPTZRequest(device,mediaProfile);

Custom requests

---

It is possible to implement your custom ONVIF request by creating a new class and implementing the OnvifRequest interface and overriding the getXml() and getType() methods.

public class PTZRequest implements OnvifRequest {
    @Override
    public String getXml() {
        return "<GetServices xmlns=\"http://www.onvif.org/ver10/device/wsdl\">" +
                "<IncludeCapability>false</IncludeCapability>" +
                "</GetServices>";
    }
    @Override
    public OnvifType getType() {
        return OnvifType.CUSTOM;
    }
}

and send it to the appropriate OnvifDevice:

onvifManager.sendOnvifRequest(device, new PTZRequest());

Use the OnvifResponseListener to receive responses from your custom requests.
