In this article we will see how we can get file size 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. File size is in the form of bytes normally the better the resolution the greater will be the file size. We can get the pafy object with the help of new method and with the help of allstreams attribute we can get 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 get_filesize method with the stream object of video
Syntax : stream.get_filesize() Argument : It takes no argument Return : It returns integer
Below is the implementation
Python3
# importing pafyimport pafy # url of video url = "https://www.youtube.com / watch?v = vG2PNdI8axo" # getting videovideo = pafy.new(url) # getting all the available streamsstreams = video.allstreams# selecting one streamstream = streams[1]# getting file size of streamvalue = stream.get_filesize()# printing the valueprint("File Size in bytes: " + str(value)) |
Output :
File Size in bytes: 554085
Another example
Python3
# importing pafyimport pafy # url of video url = "https://www.youtube.com / watch?v = i6rhnSoK_gc" # getting videovideo = pafy.new(url) # getting all the available streamsstreams = video.allstreams# selecting one streamstream = streams[4]# getting file size of streamvalue = stream.get_filesize()# printing the valueprint("File Size in bytes: " + str(value)) |
Output :
File Size in bytes: 8125774
