# pytube

*pytube* is a genuine, lightweight, dependency-free Python library (and command-line utility) for downloading YouTube videos.

## Documentation

Detailed documentation about the usage of the library can be found at [pytube.io](https://pytube.io). This is recommended for most cases. If you want to hastily download a single video, the [quick start](#Quickstart) guide below might be what you're looking for.

## 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``.

Furthermore, *pytube* includes a command-line utility, allowing you to 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

## Quickstart

This guide covers the most basic usage of the library. For more detailed information, please refer to [pytube.io](https://pytube.io).

### Installation

Pytube requires an installation of Python 3.6 or greater, as well as pip. (Pip is typically bundled with Python [installations](https://python.org/downloads).)

To install from PyPI with pip:

```bash
$ python -m pip install pytube
```

Sometimes, the PyPI release becomes slightly outdated. To install from the source with pip:

```bash
$ python -m pip install git+https://github.com/rg089/pytube
```

### Using pytube in a Python script

To download a video using the library in a script, you'll need to import the YouTube class from the library and pass an argument of the video URL. From there, you can access the streams and download them.

```python
>>> from pytube import YouTube
>>> YouTube('https://youtu.be/2lAe1cqCOXo').streams.first().download()
>>> yt = YouTube('http://youtube.com/watch?v=2lAe1cqCOXo')
>>> yt.streams
... .filter(progressive=True, file_extension='mp4')
... .order_by('resolution')
... .desc()
... .first()
... .download()
```

### Using the command-line interface

Using the CLI is remarkably straightforward as well. To download a video at the highest progressive quality, you can use the following command:
```bash
$ pytube https://youtube.com/watch?v=2lAe1cqCOXo
```

You can also do the same for a playlist:
```bash
$ pytube https://www.youtube.com/playlist?list=PLS1QulWo1RIaJECMeUT4LFwJ-ghgoSH6n
```
