Video Chat with OpenTok


The OpenTok video chat platform delivers the simplicity and customization that developers need for building modern web applications. This new API lets you call the shots. You have full control over layout, who sees whom, and who just watches.

The OpenTok API is a free and flexible cloud-based API, making it easy to add video chat to your applications without having to worry about infrastructure and scale—build your app using our simple JavaScript or ActionScript libraries.

Technical Requirements for OpenTok

End users will need the following:

  • Flash Player 10.3 or later
  • Firefox 3.0+, Safari 4.0+, Internet Explorer 7+, Chrome
  • Windows XP+, OSX 10.4+
  • A webcam and a microphone!
  • A standard DSL line with a minimum upload and download speed of 160kb per call participant

OpenTok in Linux

OpenTok does not support in Linux but it provides facility to support Linux by adding {wmode : “window”}  in session.publisher function. If video chat is not working after adding this then do the following changes :

  • Download webcamstudio for video chatting using OpenTok

Link to install webcamstudio :


  • Do the global settings of Adobe Flash Player
and choose Always Allow for and it will allow it to work properly.

Limitations of OpenTok

  • High speed internet connection is required. 
  • Global settings for Adobe Flash should be done for using OpenTok in Linux.
  • Sometimes after changes Flash settings, it doesn’t work.
  • Linux and Flash Player do not combine very well. So, we have to install Webcam Studio in Linux to fix camera acquisition problem.
