As part of my live shows, I have 3 hosts and up to 3 guests, all remote via vMix Call.

I have a 3-Up multiview arrangement that I use to put up various combinations of hosts and guests.

I also have a Green Room that when I take our guests off Program, get routed to Audio Bus C (Green Room Mix), Removed from Audio Bus A (Master Mix) and then the Video Call Audio Source is set to C also. I do the reverse for when they are 'Live'.

Sample Script for 3 Hosts on Screen in Multiview:

Function=SetLayer&Input=3-Up&Value=1,Host 1 Call
Function=SetLayer&Input=3-Up&Value=2,Host 1 L3rd Static

Function=SetLayer&Input=3-Up&Value=3,Host 3 Call
Function=SetLayer&Input=3-Up&Value=4,Host 3 L3rd Static

Function=SetLayer&Input=3-Up&Value=5,Host 2 Call
Function=SetLayer&Input=3-Up&Value=6,Host 2 L3rd Static

Function=AudioBusOn&Value=A&Input=Host 1 Call
Function=AudioBusOn&Value=A&Input=Host 2 Call
Function=AudioBusOn&Value=A&Input=Host 3 Call

Function=AudioBusOff&Value=C&Input=Host 1 Call
Function=AudioBusOff&Value=C&Input=Host 2 Call
Function=AudioBusOff&Value=C&Input=Host 3 Call

Function=VideoCallAudioSource&Value=BusA&Input=Host 1 Call
Function=VideoCallAudioSource&Value=BusA&Input=Host 2 Call
Function=VideoCallAudioSource&Value=BusA&Input=Host 3 Call[/i][/i][/i]

The problem is that I have to have every arrangement accounted for and I use almost an entire Streamdeck page to account for all the variations between Hosts and Guests. I also have the reverse scripts set for taking them off screen, so it ends up resulting in a ton of scripts and buttons. But, it does work! So it isn't the worst set up.

Is there a way I can dynamically trigger scripts based on who is Live and who is turned Off in the Multiview input?

Thanks in advance for any help and please let me know if I can provide more information!

Thanks...I have combed through the Scripting for Dummies and have tried almost 100 different scripts using API functions and various VB.Net scripts.

I have not seen any API functions that can identify multiview layer status in realtime as it changes, which seems to be the ultimate hang up.

If you know of anything specific I can look into, that would be super helpful!!

'Dynamically trigger scripts for inputs based on Mix Input Previews
Dim oldPreview(5) As String ' To store the last preview input for each Mix Input
Dim x As New System.Xml.XmlDocument

Do While True
x.LoadXml(API.XML())

' Loop through each Mix Input (2, 3, 4, 5 in this example)
For Each MixNumber As Integer In New Integer() {2, 3, 4, 5}
' Try to get the node first before accessing its properties
Dim node = x.SelectSingleNode("//mix[@number='" & MixNumber & "']/preview")

If node IsNot Nothing Then
Dim currentPreview As String = node.InnerText

' Compare with old preview input
If oldPreview(MixNumber) <> currentPreview Then
' Set the script name to start based on the current Preview
Dim scriptName As String = ""

Select Case currentPreview
Case "1"
scriptName = "Host 1 Audio In"
Case "2"
scriptName = "Host 2 Audio In"
Case "3"
scriptName = "Host 3 Audio In"
Case "4"
scriptName = "Guest 1 Audio In"
Case Else
' Here, you can specify separate Audio Out scripts for each host and guest
Select Case oldPreview(MixNumber)
Case "1"
scriptName = "Host 1 Audio Out"
Case "2"
scriptName = "Host 2 Audio Out"
Case "3"
scriptName = "Host 3 Audio Out"
Case "4"
scriptName = "Guest 1 Audio Out"
Case Else
scriptName = "Generic Audio Out" ' Fallback generic audio out script
End Select
End Select

' Run the script
API.Function("ScriptStart", Value := scriptName)

' Update old preview input
oldPreview(MixNumber) = currentPreview
End If
Else
' Handle the case where the node was not found
Console.WriteLine("Node not found for Mix " & MixNumber)
End If
Next

Sleep(500) ' Wait for half a second before the next iteration
Loop
