Pytube keyerror 'streamData' while downloading a video

Question

I was writing a code to see available streams of the video by writing below code

from pytube import Playlist
from pytube import YouTube as YT
import threading as th
import time

plist=input('Enter the playlist: ')

videos=list(Playlist(plist))
i=videos[0]
video=YT(i)
strm=video.streams.filter(res="720p")
print(strm)

from above code I got error like this

Traceback (most recent call last):
  File "D:\Practicals\Python\ML\youtube\temp.py", line 11, in <module>
    strm=video.streams.filter(res="720p")
         ^^^^^^^^^^^^^
  File "D:\Python311\Lib\site-packages\pytube\__main__.py", line 296, in streams
    return StreamQuery(self.fmt_streams)

    return self.vid_info['streamingData']
           ~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^
KeyError: 'streamingData'

I am getting the same problem for every video – Aaryan R Soni Apr 28 '23 at 11:14 — Aaryan R Soni, Apr 28 '23 at 11:14

I had the same problem and fixed it by adding the use_oauth and allow_oauth_cache attributes to YT(i).

from pytube import Playlist
from pytube import YouTube as YT
import threading as th
import time

plist=input('Enter the playlist: ')

videos=list(Playlist(plist))
i=videos[0]
video=YT(i, use_oauth=True, allow_oauth_cache=True)
strm=video.streams.filter(res="720p")
print(strm)

This will require you to connect to youtube via your browser once, but then it will allow you to download the videos.

This worked for me. Thanks so much! However, how can we get that response instead of it being printed to the console. The issue is I am using it to a tkinter app, hence the user cannot see the prompt and instruction as it is printed in the console. Thanks again – syncster31 May 02 '23 at 03:57

Got the same error while using pytube 12.1.2.

video=YT(i, use_oauth=True, allow_oauth_cache=True)

did not work for me.

After upgrading pytube (to 15.0.0), the error went away.

This should work...

from pytube import Playlist
from pytube import YouTube as YT
import threading as th
import time

DOWNLOAD_DIR = 'C:\\download\\folder'

plist=input('Enter a playlist URL: ')

videos=list(Playlist(plist))

for i in range(len(videos)):
    print(i,'-',videos[i])

    video   = YT(videos[i], use_oauth=True, allow_oauth_cache=True)
    stream  = video.streams.get_by_itag(140)
    stream.download(output_path=DOWNLOAD_DIR)
    
print('----------done---------')

This seems to repeat the solution by linomassaro an hour prior, except without any explanation. – TylerH May 01 '23 at 13:43
Okay i will try – Aaryan R Soni May 01 '23 at 16:03
May i ask one more question? Why didn't the previous code work? I mean i was using the same code for some time, and it was working fine until recently. – Aaryan R Soni May 01 '23 at 16:04
The other answer is not an _hour_ earlier, but a _day_ earlier. Please don't repeat answers. – ChrisGPT was on strike May 02 '23 at 12:34

Add this in the begining of the script.
This has done the job for me [even after a long time].

import os
os.system('cmd /c "pip install --upgrade pytube"')
