In this article we will see how we can get stream dictionary 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. Stream is basically available resolution of video is available on youtube. Dictionary consist of all the information of the stream. 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 __dict__ attribute with the pafy object of video

Syntax : video.__dict__ 

Argument : It takes no argument 

Return : It returns dictionary

Below is the implementation 

Python3




# 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[2]
 
# getting dictionary of the stream
value = stream.__dict__
 
# printing the value
print(value)

Output :

{'_itag': '140', '_mediatype': 'audio', '_threed': False, '_rawbitrate': 131072, '_resolution': '0x0', '_quality': '128k', '_dimensions': (0, 0), '_bitrate': '128k

Another example 

Python3




# importing pafy
import pafy
   
# url of video
url = "https://www.youtube.com / watch?v = i6rhnSoK_gc"

video = pafy.new(url)
 
# getting all the available streams
streams = video.allstreams
 
# selecting one stream
stream = streams[4]
 
# getting dictionary of the stream
value = stream.__dict__
 
# printing the value
print(value)

Output :

{'_itag': '278', '_mediatype': 'video', '_threed': False, '_rawbitrate': 0, '_resolution': '256x144', '_quality': '256x144', '_dimensions': (256, 144), '_bitrate': '0k', '_extension': 'webm', 'encrypted': None, '_notes':.....
