   7 Prototype of a decentralized video streaming platform using P2P (bittorrent) directly in the web browser with [webtorrent](https://github.com/feross/webtorrent).

  11 ## Why
  12
  13 We can't build a FOSS video streaming alternatives to YouTube, Dailymotion, Vimeo... with a centralized software. One organization alone cannot have enought money to pay bandwith and video storage of its server.
  14
  15 So we need to have a decentralized network (as [Diaspora](https://github.com/diaspora/diaspora) for example).
  16 But it's not enought because one video could become famous and overload the server.
  17 It's the reason why we need to use a P2P protocol to limit the server load.
  18 Thanks to [webtorrent](https://github.com/feross/webtorrent), we can make P2P (thus bittorrent) inside the web browser right now.

  20 ## Features
  21
  22 - [ ] Frontend
  23   - [X] Simple frontend (All elements are generated by jQuery)
  24   - [ ] AngularJS frontend
  25 - [X] Join a network
  26   - [X] Generate a RSA key
  27   - [X] Ask for the friend list of other pods and make friend with them
  28   - [X] Get the list of the videos owned by a pod when making friend with it
  29   - [X] Post the list of its own videos when making friend with another pod
  30 - [X] Quit a network
  31 - [X] Upload a video
  32   - [X] Seed the video
  33   - [X] Send the meta data to all other friends
  34 - [X] Remove the video
  35 - [X] List the videos
  36 - [X] Search a video name (local index)
  37 - [X] View the video in an HTML5 page with webtorrent
  38 - [ ]  Manage user accounts
  39   - [ ] Inscription
  40   - [ ] Connection
  41   - [ ] Account rights (upload...)
  42 - [X] Make the network auto sufficient (eject bad pods etc)
  43 - [ ] Manage API breaks
  44 - [ ] Add "DDOS" security (check if a pod don't send too many requests for example)

  47 ## Usage
  48
  49 ### Front compatibility
  50
  51   * Chromium
  52   * Firefox (>= 42 for MediaSource support)
  53
  54 ### Dependencies
  55
  56   * **NodeJS >= 4.2**
  57   * Grunt-cli (npm install -g grunt-cli)
  58   * OpenSSL (cli)
  59   * MongoDB
  60   * xvfb-run libgtk2.0-0 libgconf-2-4 libnss3 libasound2 libxtst6 libxss1 (for electron)
  61
  62 #### Debian
  63
  64 Install NodeJS 4.2: [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)
  65
  66     # apt-get install mongodb openssl xvfb curl sudo git build-essential libgtk2.0-0 libgconf-2-4 libnss3 libasound2 libxtst6 libxss1
  67     # npm install -g grunt-cli
  68     # npm install -g electron-prebuilt
  69
  70
  71 ### Test It!
  72
  73     $ git clone https://github.com/Chocobozzz/PeerTube
  74     $ cd PeerTube
  75     # npm install -g electron-prebuilt
  76     $ npm install
  77     $ npm start
  78
  79 ### Test with 3 fresh nodes
  80
  81     $ scripts/clean_test.sh
  82     $ scripts/run_servers.sh
  83
  84 Then you will can access to the three nodes at `http://localhost:900{1,2,3}`. If you call "make friends" on `http://localhost:9002`, the pod 2 and 3 will become friends. Then if you call "make friends" on `http://localhost:9001` it will become friend with the pod 2 and 3 (check the configuration files). Then the pod will communicate with each others. If you add a video on the pod 3 you'll can see it on the pod 1 and 2 :)
  85
  86 ### Dockerfile
  87
  88 You can test it inside Docker with the [PeerTube-Docker repository](https://github.com/Chocobozzz/PeerTube-Docker). Moreover it can help you to check how to create an environment with the required dependencies for PeerTube on a GNU/Linux distribution.

  90 ## Architecture
  91
  92 See [ARCHITECTURE.md](https://github.com/Chocobozzz/PeerTube/blob/master/ARCHITECTURE.md) for a more detailed explication.
  93
  94 ### Backend
  95
  96   * The backend whould be a REST API
  97   * Servers would communicate with each others with it
  98     * Each server of a network has a list of all other servers of the network
  99     * When a new installed server wants to join a network, it just has to get the list of the servers via one server and tell them "Hi I'm new in the network, communicate with me too please"
 100     * Each server has its own users who query it (search videos, where the torrent URI of this specific video is...)
 101     * Server begins to seed and sends to the other servers of the network the video information (name, short description, torrent URI) of a new uploaded video
 102     * Each server has a RSA key to encrypt and sign communications with other servers
 103   * A server is a tracker responsible for all the videos uploaded in it
 104   * Even if nobody watches a video, it is seeded by the server where the video was uploaded
 105   * A server would run webtorrent-hybrid to be a bridge with webrtc/standard bittorrent protocol
 106   * A network can live and evolve by expelling bad pod (with too many downtimes for example)

 112 ![Decentralized](http://lutim.cpy.re/aV2pawRz)
 113
 114 ![Watch a video](http://lutim.cpy.re/AlOeoVPi)
 115
 116 ![Watch a video P2P](http://lutim.cpy.re/fb0JH6C3)
 117
 118 ![Join a network](http://lutim.cpy.re/ijuCgmpI)
 119
 120 ![Many networks](http://lutim.cpy.re/iz8mXHug)
 121
 122 ### Frontend
 123
 124 There would be a simple frontend (Bootstrap, AngularJS) but since the backend is a REST API anybody could build a frontend (Web application, desktop application...).
 125 The backend uses bittorrent protocol, so users could use their favorite bittorrent client to download/play the video after having its torrent URI.
