Video Call App

A one-to-one text, audio and video chat application built with webRTC and Ratchet (PHP WebSockets).

Requirements

• PHP >= 5.4
• Every other required files are included or referenced as the case may be

Getting Started

To test this app on your local server:

• The Ratchet server must be ON. This can be achived by navigating to video-call-app/ws/bin from your cli and run php server.php
• Run the app from your browser at: http://localhost/video-call-app/
• Create and enter a room
• Enter the room from two different browsers (using the same link) and test by sending text chats. This can be done on the same device.
• The audio and video call is best tested on two different devices. This will require more configuration
• Open video-call-app/js/comm.js and change this line const wsChat = new WebSocket("ws://localhost:8080/comm"); to const wsChat = new WebSocket("ws://YOUR_SERVER_IP:8080/comm");
• Open video-call-app/ws/bin/server.php and add your server ip address to $allowed_origins array, then replace the localhost in $app = new Ratchet\App('localhost', 8080, '0.0.0.0'); with your ip address
• Blam! Good to go. Navigate to YOUR_IP_ADDRESS/video-call-app on your browser on two different devices to start chatting
• Works best on Chrome, Firefox and the latest versions of Opera desktop browser.

#Note To host this online, you'll need to set up a few things:

• Create Ratchet as a service so it can run persistently on your server. Check the file ratchet_as_a_service.txt for the guide on how to do this on CentOS7

• If on SSL, Ratchet won't work unless you make some changes on your server.

  • Enable mod_proxy.so

  • Enable mod_proxy_wstunnel.so

  • Open httpd.conf and add this: ProxyPass /wss2/ ws://YOUR_SERVER_IP_OR_DOMAIN:PORT/

    e.g. ProxyPass /wss2/ ws://www.abc.xyz:8080/

  • From your front-end, you can connect like this:

    const wsChat = new WebSocket("ws://YOUR_SERVER_IP_OR_DOMAIN:PORT/wss2/comm");

  However, if you are wondering how to edit httpd.conf on WHM, here is how:

  • After enabling those services (mod_proxy.so and mod_proxy_wstunnel.so), log in to WHM,

  go to "service configuration" => "Apache configuration" => "include editor" => "pre main include",

  select a version of your choice or choose "All versions". The file name should be "pre_main_global.conf'

  • All your new configuration can be written in that textarea without tampering with httpd.conf directly. The configurations will be loaded on Apache start-up.
  • Once you put the Proxypass directive there, restart your server and there you go.
