Codec Confusions: H.264 versus WebM

Fear and Loathing in Online Video: The Video Codec Conundrum Continues
(via ReelSEO Video Marketing)

My last post described, what Google’s decision to drop H.264 from Chrome in favor of its own WebM format means for you, and concluded that this situation creates even more complexity video publishers, along with the potential of a massive increase in video publishing costs.
It’s been almost two weeks now since Google made that announcement and commentary across the web all led to a similar conclusion – that Flash video is the winner in this latest codec conundrum, and now the safest bet for publishing video for the web.

Many have both lauded and lambasted Google’s decision while many others have shrugged it off as not being a really a big deal.

Regardless of the debate around “open” and “closed” standards and patents or codecs and containers – the net result of Google’s decision affects the entire ecosystem of video content creators, publishers, developers and advertisers and has created an atmosphere of fear and loathing in online video.

Google replies to criticism

Google defended its decision in follow up post on the Chromium Blog: More about the Chrome HTML Video Codec Change, where Google Product Manager Mike Jazayeri addressed some of the key questions.

Regarding Google’s decision to support WebM for HTML 


We believe there is great promise in the (video) tag and want to see it succeed. As itstands, the organizations involved in defining the HTML video standard are at an impasse. There is no agreement on which video codec should be the baseline standard. Firefox and Opera support the open WebM and Ogg Theora codecs and will not support H.264 due to its licensing requirements; Safari and IE9 support H.264. With this status quo, all publishers and developers using the
This is not an ideal situation and we want to see a viable baseline codec that all browsers can support. It is clear that there will not be agreement to specify H.264 as the baseline codec in the HTML video standard due to its licensing requirements. Furthermore, we genuinely believe that core web technologies need to be open and community developed to enable the same great innovation that has brought the web to where it is today. These facts led us to join the efforts of the web community and invest in an open alternative, WebM.


Jazayeri admitted that H.264 has broader support in the publisher, developer, and hardware community today but due to its licensing requirements and patent royalties, which could potentially increase over time, it could not back it as the baseline in the HTML video standard. He reiterated Google’s vision to create “open innovation” for video on the web, and that its significant investment in making WebM an open platform for development was proof of that. 
But Google was not abandoning H.264 altogether, Jazayeri said, and pointed out that the majority of H.264 videos on the web are viewed in plug-ins such as Flash and Silverlight, and H.264 will continue to be supported in Chrome through a plug-in as well. He admitted that this decision will force publishers to create multiple versions of their videos, but argued that it was already the case since Firefox and Opera never supported H.264 in the HTML
Additionally, Google is already doing that with YouTube videos and with the proliferation of mobile devices, platforms, and connectivity types across the web, he added that most content providers already produce multiple versions of their videos. Google is confident that WebM will emerge as a viable and compelling solution for publishers and the WebM Project team will soon release plugins that enable WebM support in Safari and IE9 via the HTML standard Jazayeri’s final point acknowledged the elephant in the room:

Bottom line, we are at an impasse in the evolution of HTML video. Having no baseline codec in the HTML specification is far from ideal. This is why we’re joining others in the community to invest in WebM and encouraging every browser vendor to adopt it for the emerging HTML video platform. Our choice was to make a decision today and invest in open technology to move the platform forward, or to accept the status quo of a fragmented platform where the pace of innovation may be clouded by the interests of those collecting royalties. Seen in this light, we are choosing to bet on the open web and are confident this decision will spur innovation that benefits users and the industry.
