So, you are on the desert with no WiFi connection but you must continue watching your favorite series on youtube. A simple solution for this will be to download the videos beforehand. While there are many YouTube video downloaders available on the net, you will surely not want to download malware with your favorite videos, will you? Therefore the preferable solution is to make your very own downloader!!
It always surprises me how easy things can be with Python. To make your own youtube video downloader you will only need 2 lines of codes(yes, you heard it right)!
And here it is. Isn't it beautiful?
from pytube import YouTube yt = YouTube('https://www.youtube.com/watch?v=sVPYIRF9RCQ').streams.download()
Don't forget to run this command before you execute the code.
pip install pytube3 --upgrade
The First line is importing the
YouTube object from the
pytube library. Then in the second line, you specify the video by adding the video URL. Then, select the first available video available
streams and finally
Isn't that simple?
Though those 2 lines of code will do the job for you, there is still scope for improvements.
Downloading a video from the above code can create the following issues.
- No indication of how much download has been completed
- Not getting the highest quality available
- A fixed download path
Let's handle the issues one by one
We will show a small progress bar indicating the amount of video got downloaded. It's is quite simple. You just need to import one extra module.
from pytube import YouTube from pytube.cli import on_progress url = 'https://www.youtube.com/watch?v=sVPYIRF9RCQ' yt = YouTube(url, on_progress_callback=on_progress) yt = yt.streams.download()
Let's talk about the changes. On the second line, we are importing the progress bar. And on the fourth line, we are mention what to do when video downloads. by
on_progress_callback=on_progress, we say the program to show a progress bar while the video is downloading.
-> |██████████████████████████████████████████████████ | 97.0%
The progress bar will look something like this.
For this, we will need to sort the list of streams. We will need to use the built-in
order_by method to sort the streams. Take a look at the following code.
from pytube import YouTube url = 'https://www.youtube.com/watch?v=sVPYIRF9RCQ' yt = YouTube(url) yt.streams.order_by('resolution').desc() yt = yt.streams.download()
You can order the streams by itags and FPS too.
To download the video at a specific path, just add the file path as an argument in
download() just like this.
from pytube import YouTube url = 'https://www.youtube.com/watch?v=sVPYIRF9RCQ' yt = YouTube(url) yt = yt.streams.download('/video')
You can add a full path too.
from pytube import YouTube from pytube.cli import on_progress url = 'https://www.youtube.com/watch?v=sVPYIRF9RCQ' yt = YouTube(url, on_progress_callback=on_progress) yt.streams.order_by('resolution').desc() download_path = '/video' yt = yt.streams.download(download_path)
So, that's it for now. If you are in a hurry and need to download a few videos, just refer to the final code. However, if you want to explore more then you can read the official documentation. I don't want to limit your imagination, but here are a few things you can try.
- Make a web app
- Make a GUI
- Add advance filtering options
I hope this post was somewhat helpful to you. And this is all I had to offer to you this time. Until next time, happy coding for you. 😊
