Pafy – Checking if stream is 3D

In this article we will see how we can check if the given youtube video stream is 3D or not 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. 3D visualization. A variety of technologies that make images and movies appear more lifelike in print, on the computer, in the cinema or on TV. Known as “stereoscopic imaging” and “3D stereo, ” people sense a greater depth than they do with 2D and feel they could reach out and touch the objects. 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 threed attribute with the pafy object of video

Syntax : stream.threed Argument : It takes no argument Return : It returns bool

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[1]

# checking if stream is 3D
value = stream.threed

# printing the value
print("3D : " + str(value))

Output :

3D : False

Another example 

Python3

# 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]

# checking if stream is 3D
value = stream.threed

# printing the value
print("3D : " + str(value))

Output :

3D : False
