Onvif - trying to understand how it works

问题:

First of all, I have no experience in working with ONVIF at all. I got myself a scholarship at a company and was asked to work with it (to control some cameras and get photos from them), but they don't know how it works either, so no-one can help me much...

I was reading through the specifications available at the ONVIF webpage but I don't really get it. I know I have to use SOAP, C (I was asked to do the app in C), XML and web services. That much I understand but I don't know how am I supposed to use them. I'm not here so that you can do the work for me (that ain't fun) I just would like to know if someone here could guide me a little about what to start learning and in which order. If there's something I forgot to explain I'll add it as soon as I can.

So, you have to start with gSOAP.

Pelco has a guide to get started with gSOAP, it is for windows but it is valid for Linux as well. As you start learning gSOAP, check the last FAQ of gSOAP about the namespaces.

Finally, on the ONVIF website there's an Application Programmers Guide, which is old but still interesting. ONVIF has a forum for all people willing to learn the protocol. It does not require you to be member to access it, you can join it for free and check all the questions there.
