Is creating new VideoWallPreset available in latest MIPSDK (2019R1) ?

Yes it is. You can create a vide wall preset using the configuration API. See how it looks in the Config API Client sample.

Ya. Thanks for the reply.

But to be more details, it is possible to set the layout and camera on view item

of the preset like how it is in Management Client?

In my scenario, I change the layout and camera on the Smart Client video wall,

then I want to save its configuration using the program I developed.

With the help of the Config API Client sample, at most I can do is create a new

Video wall preset with Name and description.

I can see that my reply comes short of delivering a solution.

Next step.

When a preset has been created you can find it under each of your Smart Wall monitors:

The Config API Client does unfortunately not display the field Defintion XML, but you can mark it all (Ctrl+A), copy it (Ctrl+C) and then paste into Notepad or another editor. I actually imagine that you will develop your own code to read and/or write this.

There is no implementation in the MIP SDK that can help you create a new valid Definition XML, but you might be able to reuse some XML created from an example and do alterations to the XML.
