Mantis Checklist – How to get started with Mantis

April 26, 2013 | By Melih O. | Developer, Mantis, Tutorial

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.

Use a browser with WebRTC support – Chrome 26, FireFox Beta, or IE9 with the Google Chrome Frame plugin.

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:

Mantis: Next-generation Cloud Technology for WebRTC

April 24, 2013 | By Badri Rajasekar | Developer, Industry News, New Products & Features, OpenTok on WebRTC

Today we’re proud to announce our latest WebRTC innovation: Mantis, a cloud-scaling infrastructure for our OpenTok on WebRTC platform.

This is another big step forward for the TokBox team as we continue to pursue our goal of providing application developers with simple yet powerful APIs. APIs that not only leverage the latest standards to deliver the best possible experience, but that are backed by a scalable, smart cloud which supports interoperability across a variety of end-points.

Firepad Plugin: WebRTC video collaboration

April 10, 2013 | By Song Zheng | demo, OpenTok API, Tutorial

Yesterday Firebase launched Firepad, a Firebase-powered open source collaborative text editor. Here’s the product pitch, Michael Lehenbauer says it best:

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.

New changes for WebRTC in Chrome 26

March 29, 2013 | By Melih O. | Developer, Industry News, OpenTok on WebRTC

A new version of Chrome is out, and with it changes in the WebRTC stack. We dug through the commit logs for Chrome 26, and found the following list of WebRTC bug fixes, enhancements, and updates that we thought were relevant to the OpenTok community:

Highlights

A lot of audio bugs in WebRTC were fixed dealing with crashes and non-standard audio bitrates
Chrome on Android can now be WebRTC-enabled by enabling a flag
Improvements to the connectivity stack in WebRTC
Ability to set media constraints for audio

Full list

Avoids crash in WebRTC audio clients for unsupported capture sample rates.
Avoids crash in WebRTC audio clients for 96kHz render rate on Mac OSX.
Enable webrtc build on android.
Set WebMediaPlayerMS network state to loading instead of loaded
- This indirectly fixes the problem where WebRTC audio is muted upon refresh. The HTMLMediaElement will try to cache fully Loaded videos when the element is destructed. This will signal to the HTMLMediaElement that the player was destroyed when loading, so it needs to recreate WebMediaPlayerMS upon destruction of the media tag.
Allowing multiple MediaPlayers to connect to WebRtcAudioDeviceImpl by sharing one WebRtcAudioRenderer.
- The audio is gone when new PeerConnection is connecting to a media stream. What is happening is that the stream will pause the existing MediaPlayer and create new MediaPlayers to associated to it. But since we only allow one WebRtcAudioRenderer to connect to WebRtcAudioDeviceImpl, the new MediaPlayers audio won’t be able to associate to stream.

Building an online Photo Booth app with Aviary

March 28, 2013 | By Song Zheng |

A few weeks ago at SXSW I had the opportunity to meet Ari Fuchs, developer evangelist at Aviary. After a few rounds of birthday drinks (I had just turned 24), I slurred a promise to him that I would play around with Aviary’s API.
