Pytube progress bar

Pytube Progress Bar

The Pytube library is a useful tool for downloading YouTube videos in Python. When using Pytube to download videos, you may want to display a progress bar to visualize the download progress. Here’s an example of how to implement a progress bar using Pytube:

Example:

from pytube import YouTube
from pytube.cli import on_progress

def download_video(url):
    yt = YouTube(url, on_progress_callback=on_progress)
    stream = yt.streams.get_highest_resolution()
    total_size = stream.filesize
    
    def show_progress_bar(stream, chunk, bytes_remaining):
        current_size = total_size - bytes_remaining
        progress = (current_size / total_size) * 100
        print(f"Downloading: {progress:.2f}%")
    
    stream.stream_to_file("video.mp4", callback=show_progress_bar)
    
download_video("https://www.youtube.com/watch?v=dQw4w9WgXcQ")

In this example, we define a function called “download_video” which takes a YouTube video URL as input. Inside the function, we create a YouTube object and specify the “on_progress_callback” parameter to the “on_progress” function provided by Pytube. This allows us to track the progress of the video download.

We get the stream with the highest resolution and obtain the total file size using the “filesize” property of the stream. Then, we define a callback function called “show_progress_bar” that calculates the current progress based on the remaining bytes and displays it as a percentage.

Finally, we call the “stream_to_file” method to download the video, passing the filename as “video.mp4” and the callback function “show_progress_bar” to display the progress in real-time. You can replace the video URL in the “download_video” function call with any valid YouTube video URL.

This example demonstrates how to implement a progress bar using Pytube. You can customize the progress bar representation and styling as per your requirements.
