Video Call App

A one-to-one text, audio and video chat application built with WebRTC and RatchetPHP.

Requirements

If you require more than two participants, check out this and this.

To test this app on your local server:

Run composer install from the root directory to install dependencies.
Set your app root (base url) in /js/config.js.
Open /ws/bin/server.php and add your domain name and/or ip address to $allowed_origins array, then replace the localhost and PORT in $app = new Ratchet\App('localhost', PORT, '0.0.0.0'); with either your domain name or ip address and Port number respectively.
Set your web socket url in /js/config.js. Ensure the domain name and port matches what you set above. Use wss for secured connection.
Start Ratchet server by executing php ws/bin/server.php from your CLI.
Blam! Good to go. Open the app on two different devices to start chatting.
Works best on Chrome, Firefox and the latest versions of Opera desktop browser.
Xirsys' free STUN/TURN servers were used. If interested, you can get a free xirsys account, rename Server.example.php to Server.php and update it with your free credentials. Alternatively, you can use any STUN/TURN of your choice.

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 create-ratchet-as-a-service-with-daemon.txt for the guide on how to do this on linux servers.
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 your apache SSL config file and add this: ProxyPass /wss-secured/ ws://WEB_SOCKET_DOMAIN:WEB_SOCKET_PORT/
  
  e.g. ProxyPass /wss-secured/ ws://www.abc.xyz:PORT/
  
  Note that you can substitute the wss-secured above with any path of your choice but you have to use the same path while connecting from the front-end as shown below.
- Update your web socket url in /js/config.js:
  
  const wsUrl = 'wss://YOUR_WEB_SOCKET_DOMAIN/wss-secured';
Please note that most browsers will not allow access to media devices except the application is running on SSL or localhost (127.0.0.1).
