How to add progress bar?

Question

Is there a way to add progress bar in pytube? I don\'t know how to use the following method:

pytube.Stream().on_progress(chunk, file_handler, bytes_remaining         


        

Answer 1

The callback function takes three arguments, not four: stream, chunk and bytes_remaining.

Answer 2

Somewhat shorter option:

yt = YouTube(video_link, on_progress_callback=progress_function)

video = yt.streams.first() # or whatever 

# Prints something like "15.555% done..." 
def progress_function(stream, chunk, file_handle, bytes_remaining):
    print(round((1-bytes_remaining/video.filesize)*100, 3), '% done...')

You can, of course, limit the progress output, for instance, to values like 10, 20, 30%... - just surround the print statement with the required if-clause.

Answer 3

from pytube import Playlist
from pytube import YouTube

previousprogress = 0
def on_progress(stream, chunk, bytes_remaining):
    global previousprogress
    total_size = stream.filesize
    bytes_downloaded = total_size - bytes_remaining 

    liveprogress = (int)(bytes_downloaded / total_size * 100)
    if liveprogress > previousprogress:
        previousprogress = liveprogress
        print(liveprogress)


yt = YouTube('https://www.youtube.com/watch?v=4zqKJBxRyuo&ab_channel=SleepEasyRelax-KeithSmith')
yt.register_on_progress_callback(on_progress)
yt.streams.filter(only_audio=True).first().download()

Answer 4

Call your progress function inside the Youtube class

yt = YouTube(video_link, on_progress_callback=progress_func)

This is your progress function

def progress_function(self,stream, chunk,file_handle, bytes_remaining):

    size = video.filesize
    p = 0
    while p <= 100:
        progress = p
        print str(p)+'%'
        p = percent(bytes_remaining, size)

This computes the percentage converting the file size and the bytes remaining

def percent(self, tem, total):
        perc = (float(tem) / float(total)) * float(100)
        return perc

Answer 5

I know this is already answered, but i came across this and for me the progress was counting down from 100 to 0. Since I wanted to fill a progress bar with the percentage value, I couldn't use this.

So i came up with this solution:

def progress_func(self, stream, chunk, file_handle,bytes_remaining):
  size = self.video.filesize
  progress = (float(abs(bytes_remaining-size)/size))*float(100)
  self.loadbar.setValue(progress)

The loadbar is my Progress Bar from PyQt5. Hope this helps someone.
