How to set up multiple NDI Outputs in Designer

Post by Naggar » 05 Nov 2020, 13:00

Hi

Can anyone tell me how I can create multiple layers in Ventuz designer and somehow set a scene/layer/port or anything to different NDI Output channels? if that is not how it works, what is the purpose of being able to set multiple NDI outputs in ventuz configuration editor?

For example I would like to have a 3D Scene with two cameras using 3D reference Layer, and set one layer to NDI output A, and another layer to NDI Output B. is this possible?

Thanks
Naggar

Hi Naggar,

You can use one pipe per NDI output and control scene loading / activation with a remoting piece of code.

Karol updated the sample code for remoting. You can find it here :
viewtopic.php?f=14&t=3407&p=12132&hilit ... emo#p12132

I don't know exactly how the resources are managed in such a situation but I know that cluster clock is shared.
Maybe dev guys could bring more answer here regarding osc listener, textures...

Regards,

Robert

I really tried using this, but I think its something different I need.
Now with UE4 integrateion, Im trying to use multipipe to get two outputs as NDI.. I dont understand how to output multiple NDIs in any way unless its used as preview/ program in V director. whenever I add multiple Outputs in AV Config (whether its NDI or Offscreen), I get a popup saying that "second output is disabled) whenever I try to run Ventuz Designer.

If anyone can tell me If possible.. how can I output two NDIs or any two "Pipes" with different feeds (Ventuz Output A + Ventuz Output B) please let me know

Designer can only render to a single Pipe.
Only Runtime can handle multiple render pipe outputs.

Okay thats good news,

Lets say i have a canvas which is 3840 x 1080.. I want to set the left half of screen to be Pipe 0 and the right half of the screen to be Pipe 1 for example.
is this something that could be done? or is there a workaround to have any two outputs with different content rendering out within the same project?
(Even if there is no preview of the second Pipe in designer - would work on runtime?)

Thanks
