Как загрузить видео с YouTube и других веб-сайтов и аудиофайлы через youtube-dl (загрузка интерфейса — веб-интерфейс)

Найдите и загрузите видео через интерфейс.

я должен написать скрипт на python и flask —

     from flask import (
    Flask, Response,
    render_template,
    request,
    redirect,
    flash,
    url_for,
    send_file,
    session,
)
import subprocess
from ydl import get_media, verify, fetch_name
from zipper import zipping
import os
app = Flask(__name__)
app.secret_key = "supposed to be a secret"


@app.route("/return-file/") 
def return_file():

    import pdb
    #pdb.set_trace()

    num_choice = session.get("choice")
    filename = session.get("filename")
    url = session.get("url")

    if num_choice == 1:
        filename_formatted = filename   ".mp3"
        location = "media/Audio downloads/{}.mp3".format(session.get("id"))

    if num_choice == 2:
        #filename_formatted = filename   ".mp4"
        #cc = get_media(url, num_choice)
        print(url)
        print('==============================================================================')

        #"youtube-dl", "--get-url", url
        #subprocess.run(["youtube-dl", "--no-check-certificate", "--get-url", url])

        #subprocess.run(["youtube-dl", "--no-check-certificate", url])

        test = subprocess.run(["youtube-dl", "--no-check-certificate", "--get-filename", url])

        print(test)

        csv = '1,2,3n4,5,6n'
        return Response(
            csv, 
            mimetype="text/csv",
            headers={"Content-disposition":
                    "attachment; filename=test"})

        #return send_file('', attachment_filename="myplot.csv")

        print('==============================================================================')
        #subprocess.run(["youtube-dl", "--no-check-certificate", url])

        #location = "media/{}.mp4".format(session.get("id"))
        #if os.path.isdir(location):
            #print('True')


    if num_choice == 3 or num_choice == 4:
        filename_formatted = filename   ".zip"
        location = "media/{}.zip".format(session.get("id"))

    #return send_file(
        #location, attachment_filename=filename_formatted, as_attachment=True
    #)


@app.route("/", methods=["GET", "POST"])

    """

    title = "YDL | YouTube Downloader"

    if request.method == "POST":

• он работает на базовой загрузке консоли … но я хочу загрузить через интерфейс … без сохранения — прямая загрузка

Вы можете использовать pytube модуль, который зависит от youtube-dl . Кажется, вы создаете приложение, но с URL-адресом видео вы можете использовать приведенный ниже однострочник для загрузки видео:

 from pytube import YouTube    
YouTube(video_url).streams.first().download(filename='file_name')
