As you may already be well aware, the Android 2.3.3 update for Nexus S and Nexus One has indeed gone out today for the greater good of humanity. What you might NOT know is that this update includes WebM support. What is WebM? It’s a relatively new media file format designed specifically for the internet. What a WebM file consists of is VP8 video codec and Vorbis audio codec compressed audio streams. Well wait, what does that mean? Let’s break it down.
First, what is VP8 video codec? It’s a technology that compresses videos in a highly efficient manner – what this means is that it’s a lot easier to load the same video you’d have otherwise been waiting longer to load than you are with this new format. This particular format, VP8, is developed by On2 Technologies, a group acquired by Google back in February 2010. Google wants to push this video format because it’s both efficient and they own the company that developed it.
Second, what is Vorbis audio codec? Vorbis is essentially to audio what VP8 is to video, compressing it for easier and lighter loading. Vorbis is an open-source audio compression tech made by the Xiph Foundation which is, in fact, NOT owned by Google. The WebM project includes Vorbis because it was found by them to be the best choice of all of the open-source options.
Because the internet’s success is built on open and freely implementable technologies like HTML, HTTP, and TCP/IP, the WebM project wants to offer this freedom in an open and free video format that is “on par with the leading commercial choices.” This format, they say, is a broadly-backed community effort aimed directly at developing this open web media format.
So, not that you needed motivation to download an update to Gingerbread, but you’re going to have support for WebM media format. So that’s pretty cool.[via Android Developers]
