How to use Progress bar in pytube? - python-3.x

Question

I want to implement a progress bar in my code, but neither the old nor the new way of implementation is working.
How to add progress bar?
this fix dosen't work in the latest version.
Here is the latest documentation
https://pypi.org/project/pytube/
from pytube import YouTube
url="https://youtu.be/J5EXnh53A1k"
path=r'D://'
yt = YouTube(url)
yt.register_on_progress_callback(show_progress_bar)#by commenting this line code works fine but no progress bar is displyed
yt.streams.filter(file_extension='mp4').first().download(path)
def show_progress_bar(stream, _chunk, _file_handle, bytes_remaining):
current = ((stream.filesize - bytes_remaining)/stream.filesize)
percent = ('{0:.1f}').format(current*100)
progress = int(50*current)
status = '█' * progress + '-' * (50 - progress)
sys.stdout.write(' ↳ |{bar}| {percent}%\r'.format(bar=status, percent=percent))
sys.stdout.flush()

Answer 1

You first need to define the progress bar function, say progress_function:
def progress_function(chunk, file_handle, bytes_remaining):
global filesize
current = ((filesize - bytes_remaining)/filesize)
percent = ('{0:.1f}').format(current*100)
progress = int(50*current)
status = '█' * progress + '-' * (50 - progress)
sys.stdout.write(' ↳ |{bar}| {percent}%\r'.format(bar=status, percent=percent))
sys.stdout.flush()
Then register the above defined function progress_function with the on_progress_callback as follows:
yt_obj = YouTube(<<youtube_video_url>>, on_progress_callback = progress_function)
Rest of the code follows:
yt_obj.streams.filter(progressive=True, file_extension='mp4').get_highest_resolution().download(output_path='/home/myusername/Videos', filename='MyVideo')
Output looks like this:
↳ |██████████████████████████████████----------------| 68.4%
Have fun!!

Answer 2

I'm using progressbar2
def progress_Check(stream = None, chunk = None, file_handle = None, remaining = None):
percent = file_size - remaining + 1000000
try:
# updates the progress bar
bar.update(round(percent/1000000,2))
except:
# progress bar dont reach 100% so a little trick to make it 100
bar.update(round(file_size/1000000,2))
yt = YouTube(url, on_progress_callback=progress_Check)
yt = yt.streams.filter(progressive=True, file_extension='mp4').order_by('resolution').desc().first().download()

Here is function used to download youtube video and display progress bar from shell:
from pytube import YouTube
from pytube.cli import on_progress
fuchsia = '\033[38;2;255;00;255m' # color as hex #FF00FF
reset_color = '\033[39m'
# url is url of youtube video to download.
def download_youtube(url):
""" Instantiates YouTube class and downloads selected video. Uses Built-in
pytube.cli function on_progress to show a DOS style progress bar. """
yt = YouTube(url, on_progress_callback=on_progress)
# following line displays title and number of times video has been viewed.
print(f'\n' + fuchsia + 'Downloading: ', yt.title, '~ viewed', yt.views,
'times.')
# creates download and downloads to subdirectory called 'downloads'
yt.streams.first().download('.\\downloads\\')
# displays message verifying download is complete, and resets color scheme
# back to original color scheme.
print(f'\nFinished downloading: {yt.title}' + reset_color)
Display colors were switched because the default progress bar is fairly bright. In event video was previously downloaded the 'Finished downloading:' message will display but the progress bar won't displayed.
Please see this Showing progress in pytube regarding the use of pytube's built-in on_progress function.

# importing YouTube from pytube
import progressbar as progress
from pytube import YouTube
def progress(streams, chunk: bytes, bytes_remaining: int):
contentsize = video.filesize
size = contentsize - bytes_remaining
print('\r' + '[Download progress]:[%s%s]%.2f%%;' % (
'█' * int(size*20/contentsize), ' '*(20-int(size*20/contentsize)), float(size/contentsize*100)), end='')
url = 'https://www.youtube.com/watch?v=qOVAbKKSH10'
yt = YouTube(url, on_progress_callback=progress)
video = yt.streams.get_highest_resolution()
video.download()
