Qt Example as starter #11

Closed wallerka77 closed 3 years ago

Hi Björn, I don't know if I have to open an issue for this... I am very happy that I could compile and install your lib libONVIF on my Raspberry Pi! Great!

It would be very helpful to have a runnable example in Qt or cpp available as a starter.

Functions: -Find camera on local network -display stream in a GUI, preferably in a Qt widget -zoom setting

I have not found anything on the net. As I said, I don't know if this is the right way here in this issue. Nevertheless I would like to thank you for your great support!!!

Hi, Some years ago I started a Qt ONVIF app that I never finished. I made this repo public some minutes ago: https://github.com/Tereius/ONVIFMonitor. I hope this gets you started with libONVIF. Furthermore libONVIF comes with a small application (named onvifinfo) that does some device-discovery, inspection. You may want to look at the source code. You may want to have a look at the ONVIF programmers guide too.

Hi Björn,

i just discovered onvifinfo and indeed it found 3 cameras in my network, yeah!!!! I am so happy!!!

i didn't think i would get this far but with your help .... Thanks!

What files are needed for onvifinfo? Maybe I can learn something from it.

Sometimes I am a little confused because there are so many files and, as you know, we had problems with the build directory before.

I tried to assimilate a main.cpp source code into a Qt widget project. Unfortunately there were a lot of errors because I probably didn't implement the libONVIF libs into the Qt pro file correctly.

Now I'll try to make your example work ...

Thanks Walter

Have a look at CMakeLists.txt:448. There you see what files are needed for onvifinfo and what libONVIF dependencies are needed. You should have a look at ONVIFMonitor; especially the two files Device.h and Device.cpp.
