Ever needed that one YouTube ad downloaded but didn't know how to get the URL? (while watch on your computer) Just copy debug infos to clipboard via right click on the viewer and then run this script. (Run in python3.6+)

getAdUri.py

import re
from tkinter import Tk

AdDocId = None
text = Tk().clipboard_get()

for line in text.split('\n'):
	x = re.search('"ad_docid": "(.+)"', line)
	if x:
		AdDocId = x.group(1)
		break
#~ print()
if AdDocId is not None:
	input(f'https://www.youtube.com/watch?v={AdDocId}')
