Я использую pytube для загрузки видео с YouTube в рамках более крупного проекта. Эта проблема вызывает часть:
from pytube import YouTube
yt = YouTube('https://www.youtube.com/watch?v=LXb3EKWsInQ&t=7s')
x = yt.streams.get_by_resolution('144p')
print(x) # output of this line is None
Однако, если я запускаю
y = yt.streams.streams.all()
print(y) # the output of this shows that several streams with res = '144p' exist
Вывод:

Теперь я не могу понять, почему yt.streams.get_by_resolution('144p') возвращает None даже если поток существует.
Подробнее: Похоже, что для всех разрешений этого видео, отличных от 360p, возвращается None.
