WebRTC Revolution in progress!

Bistri Team June 26, 2014 engineering No comments

In 2013, Bistri was the first WebRTC Vendor to publish statistics on a real usage on a production platform, based on 1.5 Million minutes of Video Calls.

But a lot has changed since last year. In addition to Google Chrome, 2 major web browsers have joined the WebRTC movement, Mozilla Firefox then Opera, enabling WebRTC on Mac OS, Windows, Linux, and Android. Thanks to Temasys’s Vendor-Independent Plugin, WebRTC works now on IE & Safari for desktops as well.

This year, the Bistri team has analyzed more than 6 months of data covering over 6 Million minutes of One-to-One Video Calls. Results are summarized and illustrated in the infographic below.

Major take-away: 76% of video-calls using WebRTC compared to 13% last year with an average call length of 17 minutes per call for the last 6 months. When the quality of the video and the audio is really good, people lose all notion of time…
Last but not least, 92% of those calls are P2P with no relay.

In the next months we will be able to measure if people prefer a no-plugin experience with Flash or if they are willing to download a plugin enabling WebRTC features within their default browser.

New WebRTC Screen Sharing for Chrome

Bistri Team June 13, 2014 engineering, tutorial No comments

Screen sharing is a really convenient feature, for business purposes, for technical support, etc.

Since version 27, Google Chrome offers a screen sharing functionality. That feature was activated with a flag [“Enable screen capture support in getUserMedia()” ].

However Google has recently decided to change the way screen sharing is implemented in Chrome.

From now on, screen sharing requires a Chrome Extension. Yes… each web site editor has to submit its own extension on the Chrome WebStore.

Now the good news: with this new implementation, you can share your entire screen or just a specific window.

As an exemple, this is how the dialog box looks like on Bistri.com when you share a screen:

Neither Firefox nor Opera has support for screen sharing yet. However, you can view a screen or a window shared from Google Chrome on both Firefox and Opera.

Tutorial

Create your own Chrome Extension, customizing the code of our Screen Sharing Extension on Git. Clone this extension and open the manifest.json: – line 2: modify the name attribute – line 15-20: set all domains allowed use this extension
Submit your Chrome Extension on the Chrome Developer Dashboard
Select the “Inline Installation” checkbox to allow inline install for your extension (documentation)
Copy the ItemID of your extension:

Add your Chrome Extension id to the init object

BistriConference.init( {
    appId: "125...445",
    appKey: "edhh64...99v35",
    chromeExtentionId: "paoa...oan",
    userName: "John Doe"
} );

Start local stream

BistriConference.startStream( "screen-sharing", function( stream ){
    // display stream into the page
    BistriConference.attachStream( stream, document.body );
} );

You can test the Bistri extension on the Bistri demo conference:
