WebM: Why We Should Be Excited
By on May 19th, 2010

WebM-Open-Video-Codec Google has just unveiled WebM – an open source royalty free codec based on VP8 by On2. If everything goes according to (Google’s) plans, WebM would become the de-facto standard for HTML5 videos. In the past, I have emphasized on numerous occasions the need for an open codec – both on TechieBuzz and on my personal blog.

Until now, two codecs were being considered for use with the <video> tag – H.264 and Theora. Unfortunately, there are considerable problems with both. While Ogg Theora is royalty free and open source, it is a technically inferior codec. Not only are the file sizes generated by Ogg Theora larger, but it also lacks hardware acceleration support. The latter is critical for mobile devices like the iPad and the the iPhone. H.264 is a superior codec, but it is proprietary. If it becomes the prevalent codec, we would be held hostage to MPEG-LA’s goodwill.

If you believe that this doesn’t affect you, then think again. MPEG-LA is legally entitled to collect royalty from both content distributors as well as (commercial) content providers. Yes, they have decided to waiver this fee til 2015. However, there is nothing stopping them from changing their minds after the initial grace period is over.

WebM offers a way out. It is a media project encompassing both audio and video. While the video codec is based on VP8 codec by On2 (Theora is based on VP3), Vorbis will be used for delivering audio. The container format is based on a subset of the Matroska media container.

WebM will be initially supported by Google Chrome, Mozilla Firefox and Opera. While Chrome had earlier chosen to support both H.264 and Theora, the latter two had opted against using the patent encumbered H.264. Now the big question is, will Apple and Microsoft back WebM?

My guess is that Microsoft will make Internet Explorer WebM compliant in time. The biggest thorn in Google’s way may be Apple. Apple has been pushing hard in favor of H.264. In fact, recently Steve Jobs had issued a thinly veiled threat against Theora. His exact words being, “A patent pool is being assembled to go after Theora and other open sourcecodecs now”.

The biggest advantage WebM has is Google and its might. While, MPEG-LA would like to go after any open codec it considers a threat, Google is a formidable target. WebM will also be getting a huge initial impetus in form of YouTube compatibility. Numerous major players have already pledged to support WebM. Besides the aforementioned browser vendors, hardware manufacturers like AMD, ARM, Broadcom, Freescale, NVIDIA, Qualcomm, and Texas Instruments will be backing the new technology. Adobe will also be supporting WebM through Flash.

If you want to get a taste of WebM go ahead and download the experimental builds of Mozilla Firefox or Opera. Google Chrome builds with WebM should be released on May 24.
