Take action when Media Encoder queue finishes?

This Applescript code checks ME's menu item File > Stop Queue and finishes when the menu item is no longer enabled. This script can be connected to e.g. Folder Action to monitor output folder and activate ME and display dialog etc.

Cheers!

set stopQueueEnabled to true
tell application "System Events"
	repeat with processItem in processes
		if name of processItem is "Adobe Media Encoder 2023" then
			set processContents to entire contents of processItem
			exit repeat
		end if
	end repeat
	repeat while stopQueueEnabled is true
		delay 10 -- seconds
		set stopQueueEnabled to enabled of item 10 of menu items of item 1 of menus of item 3 of menu bar items of item 3 of processContents
	end repeat
end tell

I'm replying to my own post here in case someone stumbles across it. I ended up:

1. Writing a little Python scrip that polls the output files until they have stopped growing. It waits for five minutes after the last change, and then exits.
2. Using ffprobe to make sure that the files that Media Encoder produced are readble.

Slightly hacky, but it seems to work.
