Does this message only appears when you load a scene?

And is it followed by immediately by an OK message?

We use one SDI port to receive camera video feed,the problem is aximmetry software instead of showing live video feed it show an image with the following text 

"exceed licensed ports."

Our setup 2 sdi input , 1 sdi output and 1 NDI output 

Do you still have this problem in the latest version?

If yes,

- Is it possible that you assigned a number to additional devices in Device Mapper that you do not use?

- Are you sure you do not use additional inputs which are not defined in the Device Mapper, but specified directly within the Flow Editor?

- Which VirtualCam compound do you use in that scene?

After doing some internal investigation on this project, it seems to me that there are more than 4 Video Input modules used in the project.

These modules can be found in number of linked compounds and groups, after doing some cleanup for these modules the problem disappeared.

But to solve this problem it takes us some time, so I was asking if there any way to find which SDI/NDI port used in Aximmetry project 

I'm glad it's solved.

Unfortunately there is no direct way to find the used ports.
What can make them a bit easier to find is to start a global search for all Video Input modules and check the Device property of each of them.

Press Shift+F,  then press Tab several time until you see G Type in the corner.  It mean that you start a global search of the graph based on the module type.

=

then start typing a part of  Video Input

You can step through the list with the arrow key, and you can select any of them by pressing Enter.
After checking the module properties you can press Shift+F again and continue with the next module.

Unfortunately this won't find modules that are inside of closed Linked Compound.
