## Demonstration

Want to see in action?

   * [Demo server](http://peertube.cpy.re)
   * [Video](https://peertube.cpy.re/videos/watch/f78a97f8-a142-4ce1-a5bd-154bf9386504) to see how the "decentralization feature" looks like
   * Experimental demo servers that share videos (they are in the same network): [peertube2](http://peertube2.cpy.re), [peertube3](http://peertube3.cpy.re). Since I do experiments with them, sometimes they might not work correctly.

## Why

We can't build a FOSS video streaming alternatives to YouTube, Dailymotion, Vimeo... with a centralized software. One organization alone cannot have enough money to pay bandwidth and video storage of its server.

So we need to have a decentralized network (as [Diaspora](https://github.com/diaspora/diaspora) for example).
But it's not enough because one video could become famous and overload the server.
It's the reason why we need to use a P2P protocol to limit the server load.
Thanks to [WebTorrent](https://github.com/feross/webtorrent), we can make P2P (thus bittorrent) inside the web browser right now.

## Installation

See [wiki](https://github.com/Chocobozzz/PeerTube/wiki) for complete installation commands.

### Front compatibility

  * Chromium
  * Firefox (>= 42 for MediaSource support)

### Dependencies

  * **NodeJS >= 8.x**
  * yarn
  * OpenSSL (cli)
  * PostgreSQL
  * FFmpeg

#### Debian

  1. Install NodeJS 8.x (current LTS): [https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions](https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions)
  2. Install yarn: [https://yarnpkg.com/en/docs/install](https://yarnpkg.com/en/docs/install)
  4. Run:

    $ apt-get update
    $ apt-get install ffmpeg postgresql openssl

#### Ubuntu 16.04

  1. Install NodeJS 8.x (current LTS): (same as Debian)
  2. Install yarn: (same as Debian)
  3. Run:

    $ apt-get update
    $ apt-get install ffmpeg postgresql openssl

#### Other distribution... (PR welcome)


### Sources

    $ git clone -b master https://github.com/Chocobozzz/PeerTube
    $ cd PeerTube
    $ yarn install
    $ npm run build

## Usage

### Production

If you want to run PeerTube for production (bad idea for now :) ):

    $ cp config/production.yaml.example config/production.yaml

Then edit the `config/production.yaml` file according to your webserver configuration. Keys set in this file will override those of `config/default.yml`.

Finally, run the server with the `production` `NODE_ENV` variable set.

    $ NODE_ENV=production npm start

The administrator password is automatically generated and can be found in the logs. You can set another password with:

    $ NODE_ENV=production npm run reset-password -- -u root

**Nginx template** (reverse proxy): https://github.com/Chocobozzz/PeerTube/tree/master/support/nginx <br />
**Systemd template**: https://github.com/Chocobozzz/PeerTube/tree/master/support/systemd

You can check the application (CORS headers, tracker websocket...) by running:

    $ NODE_ENV=production npm run check

### Upgrade

The following commands will upgrade the source (according to your current branch), upgrade node modules and rebuild client application:

    # systemctl stop peertube
    $ npm run upgrade-peertube
    # systemctl start peertube

### Development

In this mode, the server will run requests between instances more quickly, the video durations are limited to a few seconds.

To develop on the server-side (server files are automatically compiled when we modify them and the server restarts automatically too):

    $ npm run dev:server

The server (with the client) will listen on `localhost:9000`.


To develop on the client side (client files are automatically compiled when we modify them):

    $ npm run dev:client

The API will listen on `localhost:9000` and the frontend on `localhost:3000` (with hot module replacement, you don't need to refresh the web browser).

**Username**: *root* <br/>
**Password**: *test*

### Test with 3 fresh nodes

    $ npm run clean:server:test
    $ npm run play

Then you will get access to the three nodes at `http://localhost:900{1,2,3}` with the `root` as username and `test{1,2,3}` for the password.

### Other commands

To print all available command run:

    $ npm run help

## Architecture

See [ARCHITECTURE.md](https://github.com/Chocobozzz/PeerTube/blob/master/ARCHITECTURE.md) for a more detailed explication.

### Backend

  * The backend is a REST API
  * Servers communicate with each others with [Activity Pub](https://www.w3.org/TR/activitypub/)
  * Each server has its own users who query it (search videos, where the torrent URI of this specific video is...)
  * If a user upload a video, the server seeds it and sends the video information (name, short description, torrent URI...) its followers
  * A server is a tracker responsible for all the videos uploaded in it
  * Even if nobody watches a video, it is seeded by the server (through [WebSeed protocol](http://www.bittorrent.org/beps/bep_0019.html)) where the video was uploaded

Here are some simple schemes:
