Do you really want a dual MTI video codec for WebRTC?

H.264 AVC for WebRTC VP8 - Webm

Update: There is now some healthy conversation in the IETF WG around what “compliant” and “compatible” actually mean. More on this as it unfolds.

We are now in the final throes of a consensus call in the IETF around which video codec should be made mandatory for those building WebRTC apps, services et al, who wish to be considered “WebRTC Compliant”. The codec contenders are VP8 and H.264, in many forms and combinations.

This latest consensus call is for both codecs to be mandated for all WebRTC endpoints, or “dual MTI codec”. I am sure I will catch hell from someone on language but that is the essence of it. As one might expect, there are some that are in favor and some that are against a dual MTI video codec. Those in favor seem motivated to accept this based on the promise of interoperability that might follow and other reasons. As one might expect, we are all quite eager to put this debate to bed so we could get on with other work.

This is not a decision that should be made lightly. Let’s consider the implications. Imposing a dual MTI suggests that every developer that wishes to produce a WebRTC compliant app must implement both codecs.

Coming from a co-founder of an RTC toolkit vendor I can tell you that this does not sit very well with me, nor others in the WebRTC WG. One glance at the thread comments should provide some insight.

I find it difficult to agree to mandate a dual MTI codec knowing that there are a great many developers who will not want or will be in a position to implement both codecs. Yes, many WebRTC SDK vendors will support both. Even if both codecs and their transports are provided as part or could be easily added to the application at compile time it doesn’t mean that every developer will want to implement or ship both codecs.

Bottom line is, according this consensus, if developers do not implement/ship both codecs they are not considered WebRTC compliant. To me, this seems like a rather unreasonable expectation. Developers should be able to choose which codec they ship, and not be forced to do 2x the work to become compliant.

I would love to hear from other developers on this. Do you plan on implementing both VP8 and H.264 in your apps?

2014 WebRTC & ORTC Events – Fall / Winter Schedule

September

  • Sept 30 – Oct 2 / Chicago – IIT Real-time Communications Conference
    (For me, this is “the” objective gathering of the brightest technical minds in the RTC space.) Robin Raymond will be speaking on ORTC / WebRTC 1.1 and also Cloud + P2P Communications.

October

  • 30-31 Oct / Santa Clara – W3C TPAC / WebRTC WG Meeting
    (W3C Technical Plenary / Advisory Committee Meetings Week which includes WebRTC Working Group meetings. This should be a rather interesting set of meetings for the WebRTC WG, for a variety of reasons.)

Google’s open WebRTC media stack ported to QNX / Blackberry 10

WebRTC on QNX

The WebRTC media stack has been ported to QNX / Blackberry 10 as reported hy Hookflash in this Press Release below.

This does not mean that WebRTC browsers will now begin communicating with Blackberry apps written using the Open Peer SDK, well… not today anyhow.  What it does mean is Blackberry 10 developers can write apps using this new SDK to enable P2P voice, video and messaging, across Blackberry and iOS platforms using their own user identity model or mashed up with social identities.

In the sample app (pictured above) running on a production Z10 and a Alpha Z10 device, Facebook was used to map IDs.

Here is the Press Release…

BlackBerry Live 2013, Orlando Florida – May 13, 2013 – Hookflash announces beta availability of Open Peer Software Development Kit (SDK) for BlackBerry® 10, providing developers with an effective way to integrate high quality, secure, real-time, voice, video and messaging into their own BlackBerry 10 applications.

“The Open Peer SDK for BlackBerry 10 enables a completely new generation of communications integration on the BlackBerry 10 platform,” explains Hookflash co-founder Erik Lagerway. “The Hookflash team has worked tirelessly to build this toolkit and port the WebRTC libraries to BlackBerry 10. BlackBerry developers and enterprise customers can now integrate high quality, real-time, peer-to-peer (P2P), voice, video and messaging into their own BlackBerry 10 applications. People just want good quality voice, video and text communications embedded in whatever they’re doing. Open Peer enables progressive developers in medical, finance, gaming, travel and many other verticals with this next evolution of integrated P2P communications on BlackBerry 10 smartphones.”

“BlackBerry is committed to our app partners through an open ecosystem, strong platform and commitment to supporting innovation and invention,” said Martyn Mallick, VP of Global Alliances and Business Development at BlackBerry. “We are pleased to have Hookflash bring Open Peer to BlackBerry 10, enabling developers to add rich peer-to-peer communications in their apps, and enhance the customer experience.”

The Open Peer SDK for BlackBerry 10 is the most recent addition to the Open Peer, open source family of real-time P2P communications toolkits. The BlackBerry 10 SDK joins the existing C++ and iOS SDKs already available. Mobile developers creating applications across multiple platforms can now leverage the suite of Open Peer toolkits to deliver real-time P2P communications for all of their applications. The Open Peer SDKs are available in open source and can be found on Github (http://github.com/openpeer/).

Hookflash is a globally distributed software development team building “Open Peer”, new “open” video, voice and messaging specification and software for mobile platforms and web browsers. Open Peer enables important new evolution of communications; Open, for developers and customers to create with. “Over-the-top” via the Internet, where users control their economics and quality of service. “Federated Identity” so users can find and connect without limitations of service provider’s walled gardens and operating systems and “Integrated”, communications as a native function in software and applications. Hookflash founders, lead developers and Advisors previous accomplishments include; creators of the world’s most popular softphones, built audio technology acquired and used in Skype, created technology acquired and open sourced by Google to create WebRTC, and engaged inWebRTC standards development in the IETF and W3C.

Developers can register at (http://hookflash.com/signup) to start using the Open Peer SDK today.
