Onvif library encapsulation and qt project calls onvif library to realize functions such as device search and code stream address acquisition

I. Introduction:

The OnvifManager project in this article is developed and compiled under vs2010. It realizes the encapsulation and calling of the onvif library. The current project interface realizes the search for onvif, the code stream address acquisition, and the device restart interface. Other interfaces can be changed later by changing the project code. to add. The qt project myonvif calls the dynamic library generated by OnvifManager, uses QTableview to display the searched device information, supports code stream address acquisition and device restart, and supports one-click webpage access.
