YouTube Video Downloader

[mehabhalodiya]

I had a question regarding:

• Add a progress bar which shows how much the download has been completed.
• Add the option to control the quality of the video (480, 720, ...)

I have implemented this much:

Now, I don't know how can I add those functionalities together.
For code, check my PR: #620

I got a reference from one of the mentor :
" As the yt.streams.filter(progressive=True) returns a list of all types of resolutions in a sorted manner, you can modify the script to pick the available qualities and then present the user options to pick."

[<Stream: itag="18" mime_type="video/mp4" res="360p" fps="30fps" vcodec="avc1.42001E" acodec="mp4a.40.2" progressive="True" type="video">,
<Stream: itag="22" mime_type="video/mp4" res="720p" fps="30fps" vcodec="avc1.64001F" acodec="mp4a.40.2" progressive="True" type="video">]

Not knowing where to add!
Please help me.

The progress bar widget explanation can be found here: https://www.geeksforgeeks.org/progressbar-widget-in-tkinter-python . For quality control, you need to research a bit about how this library (pytube) takes the filer arguments in video downloading

Yes, but not able to do. Kindly help me!
@kaustubhgupta Can you please tell me, which lines I have to add to 'call bar in the downloader function' ?

[kaustubhgupta]

just call the bar function: bar()

[kaustubhgupta]

Make sure to sync the time of download(ETA) with progress bar

Now ?

from tkinter import *
from tkinter.ttk import *
from pytube import YouTube

root = Tk()
root.geometry('700x300')
root.resizable(0,0)
root.title("YouTube Video Downloader")

Label(root,text = 'Copy the link of the video you want to download from YouTube', font = 'arial 15 bold').pack()

# enter link
link = StringVar()

Label(root, text = 'Paste Link Here:', font = 'arial 15 bold').place(x = 270 , y = 60)
Entry(root, width = 80,textvariable = link).place(x = 32, y = 90)

# progress bar widget
progress = Progressbar(root, orient = HORIZONTAL, length = 100, mode = 'determinate')

# function responsible for the updation of the progress bar value
def bar():
    import time
    progress['value'] = 20
    root.update_idletasks()
    time.sleep(1)

    progress['value'] = 40
    root.update_idletasks()
    time.sleep(1)

    progress['value'] = 50
    root.update_idletasks()
    time.sleep(1)

    progress['value'] = 60
    root.update_idletasks()
    time.sleep(1)

    progress['value'] = 80
    root.update_idletasks()
    time.sleep(1)
    progress['value'] = 100

progress.pack(pady=10)

# function to download video
def Downloader():

    url = YouTube(str(link.get()))
    video = url.streams.first()
    bar()
    video.download()
    Label(root, text = 'DOWNLOADED', font = 'arial 15').place(x = 270 , y = 210)

Button(root, text = 'DOWNLOAD', font = 'arial 15 bold', bg = 'white', padx = 2, command = Downloader).place(x = 280 ,y = 150)

root.mainloop()

I can't review here, put this code in PR only and then I can test the code locally

• For the quality point. you can extract the quality value using Regex, then let the user choose the desired quality. After taking your input, you re-filter the search query with adding the resolution attribute. So it will be like:

yt.streams.filter(progressive=True, resolution=quality_chosen)

Need to note that the value of the quality_chosen must end with "p" character. Like "360p", "480p", etc.

• For the progress bar point, I'm still learning tkinter so can't help you much about it, but there is a builtin progress bar commandline

from pytube.cli import on_progress

See if there is a way to actually print that progress bar on the frame instead of bothering yourself with the calculation algorithm.
