When a video is running and moderator wants to speak over
and you´re alone and do not want or can not adjust the level of the video each time

For this the following Script automatically lowers the volume of the video, when input
of moderator mic receives a certain level.

Explanation for this case:
Input [4]: Mod Mic or Audio Desk IN
-> the audio level of this Input gets monitored
Input [5]: Video/Audio Source Input
-> the audio level of this input gets asjusted corresponding
to Mod talking/not talking

Code:
'1 define all variables
do while true
Dim xml as string = API.XML() 
Dim x as new system.xml.xmldocument
Dim HSLvl as string = ""
x.load("http://127.0.0.1:8088/api")
'7 read out headset level
HSLvl = x.SelectSingleNode("//input[4]/@meterF1").InnerText
'9 adjust video level corresponding to headset level
if HSLvl >= "0.02"
api.function("SetVolumeFade", input:= 5, value:= "50,500")
sleep(1000)
else
api.function("SetVolumeFade", input:= 5, value:= "100,500")

end if

'console.writeline(HSLvl)

loop


Maybe you have to play a little with levels, fade times and gap between if/else (sleep(1000))
without a short gap it´s a mess :-)
"'7" numbers are only for debugging as well as console.writeline...
