Secure Frames (SFrames): end-to-end media encryption with #webrtc now in chrome.

~ agouaillard ~ 4 Comments

A Story of three years of work, by multiple partners.

  • 12-MAY-2020: The original (2017) draft for PERC-Lite has been uploaded as an informal IETF Draft here.
  • 19-MAY-2020: A more recent and more formal version of SFrame has been uploaded as a standard track IETF draft here.

For several Years now, CoSMo has been providing end-to-end encryption solutions, from clients to media servers and more, fully webrtc compliant, to many. The most famous customer is maybe Symphony Communications, using an early modified version of PERC called PERC-lite, but there are many more using the second generation version called SFrame co-developed originally by Google, including the real-time streaming platform MilliCast.com for the customers in need of something better than DRM.

There was a catch though, it would not work in Browsers, one would have to go native only. Not a problem for most mobile apps, and DUO has been leveraging it for more than a year now, but still, less than ideal. Since last week, it is now possible to support SFrame in the browser. So the cat is out of the bag.

In this post we will give you some technical details about SFrame, how it is better than PERC’s double in terms of overhead, and provide a free, open-source working example, with an E2EE ready SFU! Obviously, it is nowhere close to the quality you can get from the full CoSMo E2EME packages, and don’t get me started on the key exchange, but it will illustrate the concept.

AV1 Availability in Chrome: The tentative Roadmap

~ agouaillard ~ Leave a comment

The work to add RTC AV1 in Chrome, which started in November last year is now well underway. Many people still ask the legitimate question: when will it be available and how good will it be. We had planned to deliver the implementation at IETF in Vancouver at the end of the month and make demos, but the IETF like many other events has been cancelled, so we are switching to weekly updates until the release, still planned for April. This post provides some information about both timing and quality questions.

#WebRTC Jobs !

~ agouaillard ~ Leave a comment

With all of CoSMo businesses growing, especially our Millicast real-time streaming platform doing 10x revenue YoY, and on track for +65% this Quarter (eq. to 7x annual), time has come again to hire.

We are duplicating our operation team, adding a Singapore Center in addition to the Existing US center based in California. As a result, we are opening a mid-level to senior Media DevOps position in Singapore, co-located with our global HQ, most of the C-Level, and the R&D team.

I took the opportunity to create a “Jobs” section in this blog. Do not hesitate to come back and visit, as we are likely to open more position as the year advance.
