I can't get the video link

Question

I'm trying to get a link to a video, but I'm getting an error. I don't know how to fix this. I spent a lot of time looking for a way to fix it, but I don’t have the strength anymore. Help :) My code:

from pytube import YouTube

link = "https://www.youtube.com/watch?v=9pmsuKWKf90"
yt = YouTube(link)
print(yt.streams)
itag = 137
url = YouTube(link).streams.get_by_itag(itag).url
print(url)

Traceback

  File "D:\Python\ffmpeg\link_video.py", line 5, in <module>
    print(yt.streams)
  File "D:\Python\ffmpeg\venv\lib\site-packages\pytube\__main__.py", line 295, in streams
    self.check_availability()
  File "D:\Python\ffmpeg\venv\lib\site-packages\pytube\__main__.py", line 233, in check_availability
    raise exceptions.LiveStreamError(video_id=self.video_id)
pytube.exceptions.LiveStreamError: 9pmsuKWKf90 is streaming live and cannot be loaded

Let me clarify: need to get a link to download the stream. The question is relevant

Answer 1

You cannot print it because it is a livestream, and that functionality is not supported.

EDIT: You can access data of a livestreamed video using the following code (m39SPyU3abg is the video id of a currently livestreaming video; it may not be live streaming when you use this code). I kept it in Python, but did not use Pytube, since Pytube is not designed for live streaming.

SECOND EDIT: The url is constructed from the video_id. You do have the video_id, correct? If you also have the channel_id, you would not need to make an API call and could construct the url yourself. But if you do not have it, this code determines the channel_id and creates the url:

import requests

api_key = 'YOUR_API_KEY'

video_id = 'qlPLXYKoRIU'

url = f"https://www.googleapis.com/youtube/v3/videos?id={video_id}&key={api_key}&part=snippet,contentDetails,statistics,status"

response = requests.get(url)
data = response.json()

ab_channel= data['items'][0]['snippet']['channelId']
constructed_url = f"https://www.youtube.com/watch?v={video_id}&ab_channel={ab_channel}"

print(constructed_url)
