This guide covers the most basic usage of the library. For more detailed information, please refer to pytube.io.

Installation

Pytube requires an installation of Python 3.6 or greater, as well as pip. (Pip is typically bundled with Python installations.)

To install using github:

$ python -m pip install git+https://github.com/javad-rzvn/pytube

Usage

If you have internet problem, you should use proxy. To do that, you better setup a v2ray connection, then use its proxy to download videos.

Download single video from youtube channel

from pytube import YouTube
from pytube.cli import on_progress

YouTube("https://youtu.be/2lAe1cqCOXo").streams.first().download()
proxies = {"http": "socks5://127.0.0.1:2080"}
yt = YouTube(
    "http://youtube.com/watch?v=2lAe1cqCOXo",
    on_progress_callback=on_progress,
    # on_complete_callback=complete_func,
    proxies=proxies,
)
yt.streams.filter(progressive=True, file_extension="mp4").order_by(
    "resolution"
).desc().first().download()

Download all channel's videos

In the example below, it downloads only 3 videos of the channel.

from pytube import Channel

proxies = {"http": "socks5://127.0.0.1:2080"}
c = Channel('https://www.youtube.com/c/FalcomMusicChannel/videos', proxies=proxies)

print(f'Downloading videos by: {c.channel_name}')
print(f'Channel URLs: {c.video_urls[:3]}')

for i, video in enumerate(c.videos[:3]):
    print(c.video_urls[i])
    video.streams.first().download()
