Have you enable "Send Trackables" in the Output Configuration? and match the Trackable ID & tracking name in Watchout. Old version(BT) Settings are bit difference. Please share us some screenshots of the Output Configuration.

You can capture the source by using capture card or NDI.

how about output using NDI?

What actual "spout" function do you need?

you can send "value" to Watchout through tcp/ip command. to control such as position, scale, opacity, color value...etc.

What kind of codec are you using?

Check the universe. and go ONLINE.

I dont think you can get 6outputs on nuc8i7BEH. seems do not have 6 output ports. and also version 5.5.2 not support windows 10 https://knowledge.dataton.com/knowledge/does-watchout Not sure where are you from, but i believe you can rent version 6 dongles for testing.

setInput not setinput capital i

Watchout User Guide 6.4.1 P.176 have list of commands. run and halt are the play/pause command. Enjoy.

Have you linked between s400, and setup the sync "source" correctly? and how many processor are you using?

May I know where are you from and when did you attend certified training?

use Task!

Watchout support HAP ALPHA , NOT HAP Q ALPHA. make sure you convert the right codec.

If you do not need Geometry correction and blending function from Watchout, then you will be fine. if not, It will become very complicated to do the geometry correction for FOUR 1920x1080 in one display(3840x2160) output.
