CreatePullPointSubscription

[quonn77]

I am playing with your example (WsNotificationTest) about the capability to register to the events generated by the camera. I am was not able to create a pull point subscription, I suppose, for a malformed request. Playing with soapUI I found that using a request like the one generated by the stubs into the library generate an error of type "failed to parse topic expression", If I try to manually change the SOAP request it seems to work. Here follow the two requests:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
	<soap:Header>
		<wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" soap:mustUnderstand="true"><wsse:UsernameToken wsu:Id="UsernameToken-fb13b6a5-d87b-4662-92fd-5b4abefbe264"><wsse:Username>onvifadmin</wsse:Username><wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">e+HhUWCDpzfUdMX4k0b9gwMH3RM=</wsse:Password><wsse:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">cFSFXKKlQ92SjSxV1LciFA==</wsse:Nonce><wsu:Created>2018-06-11T14:12:32.729Z</wsu:Created></wsse:UsernameToken></wsse:Security>
	</soap:Header>
	<soap:Body>

		</ns2:CreatePullPointSubscription>
	</soap:Body>
</soap:Envelope>

This generates a failure:

This one instead seems to work:

Have you got any news or idea about it?

I need to read the actual pan and tilt position of the encoder so I am assuming that the events subscription is the proper way to go, but I am not sure of this. Do you have any hints about it?

[fpompermaier]

Unfortunately I've got no idea...I migrated the WS to CXF in order to be able to use WS-Notifications but then I dind't find the time to play with it..

[quonn77]

But do you have some ideas about how to catch the actual pan and tilt position?

[fpompermaier]

I think you should first call another ws to ghet those params but I don't know which one

[quonn77]

Reading here: https://support.videotec.com/hc/en-gb/community/posts/203483685-How-can-I-get-the-current-position-of-an-integrated-PTZ-
It seems that the GetStatus could be the command to invoke, but this returns only IDLE or MOVING....So I need to further investigate about it.

[quonn77]

It's my fault....I have not seen the full response. It answer me the pan, tilt and zoom position. So I have just to convert between spaces

 <tt:PanTilt space="http://www.onvif.org/ver10/tptz/PanTiltSpaces/PositionGenericSpace" y="-0.589999974" x="-0.899999976"/>
 <tt:Zoom space="http://www.onvif.org/ver10/tptz/ZoomSpaces/PositionGenericSpace" x="0.727272749"/>

The goal is to create a FOV rendering. So I think I can arrange this kind of service directly inside the onvif library, One could provides a callback/listener to be invoked when data changes. I will work on it next days...

Great! 👍
