Hello Guys, Today I am going to create a youtube downloader GUI app to download youtube videos. I have used pytube python library to download youtube videos. Pytube is a very serious, lightweight, dependency-free Python library (and command-line utility) for downloading YouTube Videos.

According to their official documentation -

Description

YouTube is the most popular video-sharing platform in the world and as a hacker, you may encounter a situation where you want to script something to download videos. For this I present to you pytube.

pytube is a lightweight library written in Python. It has no third-party dependencies and aims to be highly reliable.

pytube also makes pipelining easy, allowing you to specify callback functions for different download events, such as on progress or on complete.

Finally, pytube also includes a command-line utility, allowing you to quickly download videos right from the terminal.

Features

Support for both progressive & DASH streams
Support for downloading the complete playlist
Easily register on_download_progress & on_download_complete callbacks
Command-line interfaced included
Caption track support
Outputs caption tracks to .srt format (SubRip Subtitle)
Ability to capture thumbnail URL
Extensively documented source code
No third-party dependencies
