Virtual Video Wall Controller

 

I need to spilt virtual video wall to custom number of screen so I can show different videos in different screen 

for example  spilt virtual video wall to 3x3 screen I show video a in 3 screens and video b in second screen .

and then maybe make video a shownew as full screen 

how to do such a thing  in aximmetry?

If you want to do the splitting for a matrix wall, you can do it with the Splitter module.

You have to setup the number of columns and rows on your wall:

You can also compensate the monitor borders sizes (unless you use borderless monitors for the wall):

You have to adjust them it until you find the result visually satisfying.
In this case you need negative values which means removing strips from the video according to the borders sizes.
(Positive values are for the case when you use multiple projectors for a large image and you need to hide the edges by overlapping the projection areas.)

Similarly you can use another splitter for another video and expose all slices,  or you can simple expose the video itself, if you do not need splitting.

However there's a problem with this. This method only works if you have as many video outputs on your video card (or cards) as the total number of slices you need.
Therefore for driving a 3x3 or larger video wall it's a better solution to use a dedicated video wall hardware and output the whole video from Aximmetry and leave the splitting to the external hardware.

But what I about to do are

1-show number of different videos on 3x3 screens

2-when operator click on button video wall split to 2 screens

3-then if the operator need one video is shown of all video screen

please note this is virtual video wall

maybe something like this

Also what about audio of videos?

You can use the Sticker module which is the opposite of the Splitter module I described before.
It can arrange multiple videos into a matrix of arbitrary number of rows and columns.

If you need to put your videos to arbitrary positions/sizes, or overlap them, use a series Placer Precise modules.

Then output the result as a single image towards the video wall hardware.  If necessary you can use 4K or 8K output for very large video walls.

For an art event in a college I have set up a digital signage video wall over 5 screens with the help of a professional team. I guess the easiest way is rendering out 5 different video's and playing them using a media player on each screen. I don't remember the technology they have used. But you can check with these guys if you want to know about it - https://om.prosignsglobal.com/digital-technology/
