Mantis Checklist – How to get started with Mantis

| By | , ,

We just launched Mantis yesterday, and saw a rush of activity as partners hopped onto the WebRTC cloud. The new things people will be able to build – a real-time, online dungeons and dragons web app, seminar applications, education applications, and more – are now going to see a whole new level of quality and experience. We’re really excited to be the face-to-face video platform that helps make this happen. But to make it happen more quickly, we’ve decided to write a quick Mantis checklist. To make your Mantis application work, you will need to:

  • Make sure that you are using the OpenTok on WebRTC JS library. You can find the library here, and find the reference documentation here. If you are using the v1.1 JS library, you will need to update your application to the v2.0 library.
  • When you generate a session, make sure that the p2p.preference flag is set to disabled. If you’re generating your sessions from the Developer Dashboard, then you will need to download one of our server-side SDKs and generate sessions yourself.
  • If you haven’t already asked to participate in the Mantis beta, please contact us at mantis@tokbox.com. Then make sure that you are using the correct API key for the Mantis beta. If you are not sure which API key you sent us, then please email us, and we will let you know. Mantis requires that your API key be enabled to access the infrastructure.

It really is that quick, and if you’re finding that you need some more help, then let us know. To make sure that your question gets answered as quickly as possible, please send an email to support@tokbox.com using the following template:

Firepad provides true collaborative editing, complete with intelligent OT-based merging and conflict resolution. It’s full-featured and has support for both rich text and code editing. Some of its features include cursor position synchronization, undo / redo, text highlighting, user attribution, presence detection, and version checkpointing.

Parse has OpenTok iOS SDK’s back(end), so you don’t have to

| By | ,

Developing an iOS App itself is a huge undertaking: you want your product to be beautiful, interactive, and functional. That’s why Parse makes so much sense, it helps you avoid writing a backend server to power your App by giving you a data store and providing the most basic web services. These days many web services are incredibly powerful and help developers do really amazing things, like OpenTok, but they are targeted at having a backend. That’s where Parse Cloud Code comes in: it gives developers the ability to leverage the best of a back-end server in the path of least resistance.

Generating Tokens without Server Side SDK

| By | , ,

During AngelHack, Alexander Ramirez came up to me with a puzzle. “How do I generate sessions and tokens?” He asked. Normally, I would have told him to use one of our server side SDKs, but he was building a browser plugin with video chat and wanted to use our REST API instead. Getting the SessionId is easy, it’s a simple POST request. However, generating token is not so straightforward because it is generated algorithmically. This tutorial will show you how to generate a token, and examples used here will be written in JavaScript.

WebRTC Demo Day! Unless you have been living under a rock, you have heard of WebRTC. A few weeks ago, Google unleashed Chrome 23 which has WebRTC and PeerConnection support. This is really exciting because everyone on chrome (and IE users with Chrome Frame plugin) can now experience the next generation of communication via live video. Today is the day to experience it. Simply go to https://OpenTokRTC.com and join a room! If you’re lucky, you might catch a few WebRTC Streams from iOS devices.
