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
Cheers
Monte
