Hi John

If you go digging in the livecode app bundle you will find an Ext/mergAV <version> folder. In there will be a very rough stack that I use for testing stuff.

The basics are:

on openCard
    if the environment is “mobile” then
         mergAVRequestMediaAccess “audio"
    end if
end openCard

on mergAVMediaAccess pType, pGrated
     put "mergAVMediaAccess"&&pType, pGrated
     if pType is "audio" then
         mergAVRequestMediaAccess “video"
    else
         mergAVCamCreate
         mergAVCamSet "rect",the rect of grc "cam"
         mergAVCamSet "visible",”true"
         mergAVCamStartBarcodeReader
     end if
end mergAVMediaAccess

on mergAVCamBarcodeFound pBarcode, pType
    answer "Barcode found"&cr&pBarcode & cr & "of type " & pType
end mergAVCamBarcodeFound

on closeCard
    mergAVCamDelete
end closeCard
