In this article we will see how we can get the itag value of the given youtube video stream in pafy. Pafy is a python library to download YouTube content and retrieve metadata. Pafy object is the object which contains all the information about the given video. Itag is a youtube is a static youtube video format.

We can get the pafy object with the help of new method and with the help of allstreams attribute we can get the all the streams available for the video, below is the command to get the pafy object for given video

video = pafy.new(url)
streams = video.allstreams

The video url should exist on youtube as it get the information of those videos which are present on the youtube. YouTube is an American online video-sharing platform.

In order to do this we use itag attribute with the pafy object of video

Syntax : video.itag



Argument : It takes no argument

Return : It returns string

Below is the implementation




# importing pafy
import pafy 
    
# url of video 
url = "https://www.youtube.com / watch?v = vG2PNdI8axo"
    
# getting video
video = pafy.new(url) 
  
# getting all the available streams
streams = video.allstreams
  
  
# selecting one stream
stream = streams[7]
  
# getting itag of the stream
value = stream.itag
  
# printing the value
print("Itag : " + str(value))

Output :

Itag : 242

Another example




# importing pafy
import pafy 
    
# url of video 
url = "https://www.youtube.com / watch?v = i6rhnSoK_gc"
    
# getting video
video = pafy.new(url) 
  
# getting all the available streams
streams = video.allstreams
  
# selecting one stream
stream = streams[4]
  
# getting itag of the stream
value = stream.itag
  
# printing the value
print("Itag : " + str(value))

Output :

Itag : 278
