How to choose a different download method in YoutubeDL?

Question

YouTube

Good afternoon! If you upload a video of any DASH format via youtube_dl (in my case 298) immediately:

from youtube_dl import YoutubeDL
with YoutubeDL({'outtmpl': 'test.mp4', 'format': '298'}) as ydl:
  ydl.download(["https://www.youtube.com/watch?v=LXb3EKWsInQ'])

, then all 90 MB will be loaded in a couple of seconds.

But if you first get a direct link to a video of the same format and download it:

with YoutubeDL({'outtmpl': 'test.mp4'}) as ydl:
  info_dict = ydl.extract_info('https://www.youtube.com/watch?v=LXb3EKWsInQ', download=False)
  url = [i for i in info_dict['formats'] if i['format_id'] == '298'][0]['url']
  ydl.download([url])

, then the same 90 MB will be loaded in a few minutes.

So I think that in the first case, youtube_dl chose the appropriate download method for the video, but in the second it could not. Is it possible to somehow select the desired method and download through it?

Answer 1

In youtube_dl solved it like this:

filename = 'test.mp4'
url = '...' # Прямая ссылка на нужный формат видео
youtube_dl.downloader.HttpFD(YoutubeDL({}), {}).download(filename, {'url': url, 'downloader_options': {'http_chunk_size': 10485760}})

Loads fast just like I wanted.

Answer 2

It's better to download YouTube videos through the pytube library. It works a little faster than youtube_dl. Yes, and write only one line of code (not counting imports and inputs).

from pytube import YouTube
link = input()
YouTube(link).streams.first().download()
