@corporatejames, can you share your functions.xml?

This is the current one but once I add all the inputs to vmix I will finish this as needed.

Just had an idea. How hard would it be to add the NDI.api with Monitor object that you could add to the page
as required like add Camera 1 video monitor (selected ndi source via dropdown menu) to the display so the person controlling the Vmix Production from a laptop
can see the NDI outputs sources from the Main Production pc of Vmix. So you would select NDI Monitor from the create menu then choose the NDI Source for the Monitor.
With ability to add as many monitors as possible with available bandwidth and cpu/memory resources on the pc that is running the controller. Monitors could have resize handles to size to the layout needed. Not sure if possible or how hard to add to the current code but would super handy and very cool.

Thats great solution, I have my own xaml titles
I have xaml title and I enter 18 players for soccer + coach. Every field of it is special like:
PlayerNumber1 PlayerName1
PlayerNumber2 PlayerName2

I enter that 2 times, each time 18 players for two teams and I can export that in csv. So for UTC can I for red, score, yellow upload that csv so I don't need to write the names again?

Nice work

1st post updated:
Added NDI Monitor Data Provider (based on example from NDI SDK),
Updated some code in external data widget,
Fixed bug (button script "forgets" input number after state updating).

VmixUTC with new NDI Monitor vMixUTCNDIMonitorDataProvider.dll

Just some quick feedback. Win 10 reports the exe as a possible threat. You have to tell it to run. Avast sees it as a threat and quarantines the file. Regards.

Ok got it. I must had old code, as I copied over the folder on the laptop. Fresh updated VmixUTC > now NDI dropdown box appears from NDI sources working. This time it did ask me to add VMicUTC to Firewall.

No worries. All working now. Thanks for quickly add in the code. If can remove the properties button it will look cleaner but realise your using the same External controller function as the Data XMl feed. Great job. Will think of some other suggestions for features and changes as I play.

Does not seem to process the NDI.Lib.x64.dll and Processing.NDI.Lib.x86.dll libs all the time
if open and close a couple times it then works again or if run as administrator it works

@corporatejames, as a workaround you can attach same hotkeys to +1 command on scoreboard, and button, that shows overlay.

Maybe I just make native command to add score in button widget.
