Pafy – Getting Resolution of Stream

  • Last Updated : 20 Jul, 2020

In this article we will see how we can get the resolution 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. Resolution is the quality of the video stream, the most popular standard resolutions are 640×360 and 640×480 for video, and 720×480 and 720×576 for DVD. HD video usually has a resolution of 1280×720 (720p) or 1920×1080 (1080p, is also known as Full HD). For audio resolution value is 0

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 resolution attribute with the pafy stream object of video

Syntax : stream.resolution

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[1]
  
# getting resolution of stream
value = stream.resolution
  
# printing the value
print("Resolution : " + str(value))

Output :

Resolution : 0x0

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 resolution of stream
value = stream.resolution
  
# printing the value
print("Resolution : " + str(value))

Output :

Resolution : 256x144
