Cisco’s OpenH264 Now Part of Firefox

Voice and video communications over IP have become ubiquitous over the last decade, pervasive across desktop apps, mobile apps, IP phones, video conferencing endpoints, and more.  One big barrier remains: users can’t collaborate directly from their web browser without downloading cumbersome plugins for different applications.  WebRTC – a set of extensions to HTML5 – can change that and enable collaboration from any browser. However, one of the major stumbling blocks in adoption of this technology is a common codec for real-time video.

The Internet Engineering Task Force (IETF) and World Wide Web Consortium (W3C) have been working jointly to standardize on the right video codec for WebRTC. Cisco and many others have been strong proponents of the H.264 industry standard codec. In support of this, almost a year ago Cisco announced that we would be open sourcing our H.264 codec and providing the source code, as well as a binary module that can be downloaded for free from the Internet. Perhaps most importantly, we announced that we would not pass on our MPEG-LA licensing costs for this binary module, making it effectively free for applications to download the module and communicate with the millions of other H.264 devices. At that time, Mozilla announced its plans to add H.264 support to Firefox using OpenH264.

Since then, we’ve made enormous progress in delivering on that promise. We open sourced the code, set up a community and website to maintain it, delivered improvements and fixes, published the binary module, and have made it available to all. This code has attracted a community of developers that helped improve Read More »

Summary: No consensus at IETF, but it’s not over yet

Recently Cisco made significant efforts around open sourcing our H.264 implementation, including covering the MPEG-LA licensing costs for distribution and working with Mozilla to add support for H.264. However, in this attempt to unstick the logjam that has occurred in the standards bodies, the Internet Engineering Task Force (IETF) failed to reach consensus on the selection of a common video codec.

Cisco’s Jonathan Rosenberg explored this topic more in a recent Collaboration blog post. Read on to find out how we’re planning to move forward and why this conversation is definitely not over!

No Consensus at IETF, But It’s Not Over Yet

Cisco recently announced that we would open source our H.264 implementation under favorable open source terms, and more importantly, provide a binary distribution of that implementation that could be downloaded and integrated into browsers and other applications. We said we’d cover the MPEG-LA licensing costs for this distribution as well. Mozilla responded by saying that, based on this, they would add H.264 to Firefox, using our technology.

Part of our motivation for making this announcement was to unstick the logjam that has occurred in the standards bodies. The Internet Engineering Task Force (IETF) is defining the standards for how real-time voice and video will work natively in the browser. Selection of a common video codec is part of that process. The group has been highly divided on this topic, with two camps – one (including Cisco), in favor of industry standard H.264, and others in favor of Google’s VP8 technology.

We hoped that our announcement, and Mozilla’s agreement to support H.264 as a common codec, would provide enough impetus to sway the standards to a concrete decision so that the industry could move forward. Alas, that was not the case. Despite what we felt was a fairly objective analysis on the reasons why H.264 was a better choice for the overall success of real-time communications on the web (click here for a recording), the IETF failed to reach consensus.

Obviously, we’re very disappointed by this. Read More »

Open-Sourced H.264 Removes Barriers to WebRTC

When it comes to making collaboration technology such as high-definition video open and broadly available, it’s clear that the web browser plays an important role. The question is, how do you enable real-time video natively on the Web? It’s a question that folks are anxious to have answered.

WebRTC–a set of enhancements to HTML5–will address the issue head on. But, there is an important hurdle that must first be cleared, and that’s standardizing on a common video codec for real-time communications on the web – something the Internet Engineering Task Force (IETF) will decide next week.

The industry has been divided on the choice of a common video codec for some time, namely because the industry standard–H.264–requires royalty payments to MPEG LA. Today, I am pleased to announce Cisco is making a bold move to take concerns about these payments off the table.

We plan to open-source our H.264 codec, and to provide it as a binary module that can be downloaded for free from the Internet. Cisco will not pass on our MPEG LA licensing costs for this module, and based on the current licensing environment, this will effectively make H.264 free for use in WebRTC.

I’m also pleased that Mozilla has announced it will enable Firefox to utilize this module, bringing real-time H.264 support to their browser.

“It hasn’t been easy, but Mozilla has helped to lead the industry toward interoperable video on the Web,” said Brendan Eich, Mozilla Chief Technology Officer. “Cisco’s announcement helps us support H.264 in Firefox on most operating systems, and in downstream and other open source distributions using the Cisco H.264 binary module. We are excited to work with Cisco on advancing the state of interoperable Web video.”
