I am sure you already know the answer by now, but I will answer for others searching the same topic. You can do this by using Pafy. First you need to import pafy

然后添加此

url = "https://www.youtube.com/watch?v=_9OBhtLA9Ig"
video = pafy.new(url)
best = video.getbest(preftype="mp4")

capture = cv2.VideoCapture()
capture.open(best.url)

应该就是这样.
