Adobe reveals Flash-to-HTML5 converter Wallaby

The problem with Adobe’s Flash for most consumers, as anyone with an Apple iPhone/iPad is acutely aware of, is that it is not universally supported by all mobile platforms. Google’s Android OS didn’t get Flash until version 2.2 and there is still some time to go yet before support is added to the tablet-centric 3.0 Honeycomb update, but the runaway success of Apple’s iDevices has left a sizable number of mobile tech users without access to chunks of the Internet.

Apple has instead put a big push behind the less hardware-intensive HTML5, which a number of popular websites — notably YouTube — have converted to or offer support for. In recognition of this, Adobe has pulled back the veil on an experimental file conversion application called Wallaby which is designed to turn your Flash files into HTML. It is a developer-focused release, so you won’t be able to put this on your phone and start browsing through Flash-driven pages.

Instead, the intent with this initial offering is to give advertisers a workable solution for bringing their Flash-based ads to iOS devices, as it says in the Wallaby release notes. Awesome. That Flash-driven website still gives you the frowny face icon whenever you load it, but at least the Extenze ad at the top of the page is fully animated!

In all seriousness, this is at least a first step. The initial release of Wallaby doesn’t support the conversion of ActionScript, movies or sound, but Adobe is working on implementing these features and more. For now the application simply takes your supported Flash content and converts it to a mix of HTML, CSS and JavaScript code, which can then be edited or simply dropped into a webpage.

Google Drops Support for H.264 Video In Favor Of WebM

In a blog post, Google has reversed a previous decision to support H.264 video in Chrome. Instead, it will support WebM. The codec wars are beginning to feel more like a bad lead-up to a high school dance.

Google has dumped HTML5 support for H.264 video from its Chrome browser, a codec that appeared on the brink of replacing Flash video as the industry standard. In its place, the ‘open’ Chromium project will now support WebM (VP8) and Theora video codecs in HTML5 tags. Though nicely worded in a brief blog post, the move is an odd mirror to Steve Jobs’s own declaration against Flash last year.

“Though H.264 plays an important role in video, as our goal is to enable open innovation, support for the codec will be removed and our resources directed towards completely open codec technologies,” said Mike Jazayeri, product manager for Chrome.

Codecs are a messy business, but some are questioning Google’s motives in dropping H.264. After all, if it is dropping support for H.264, why does it still continue to support Flash video, a completely closed standard?

For those unfamiliar, codecs translate video and audio, encoding them and decoding them. Much like MP3s, they attempt to crunch down and compress data, while maintaining the highest quality output possible. Flash has been the most popular technology that allowed video to be streamed on the Web. It’s completely controlled by Adobe and uses its own internal set of codecs to make this possible. However, HTML5 includes built in support for video, eliminating the need for plug-ins like Flash. H.264 is free, but still a codec owned by MPEG LA, which could begin charging for it at any time.

So WebM is where Google’s vote now lies in the great debate over Web video. Will Apple and Mcrosoft follow suit? Certainly Mozilla is happy. The organization banished H.264 from its FireFox browser last year.

Apple Launches HTML5 Showcase

The demos show how the latest version of Apple’s Safari web browser, new Macs, and new Apple mobile devices all support the capabilities of HTML5, CSS3, and JavaScript. Not all browsers offer this support. But soon other modern browsers will take advantage of these same web standards — and the amazing things they enable web designers to do. NOTE: You can view the showcase in Safari ONLY.

What is HTML5

HTML5 is a new version of HTML and XHTML. The HTML5 draft specification defines a single language that can be written in HTML and XML. It attempts to solve issues found in previous iterations of HTML and addresses the needs of Web Applications, an area previously not adequately covered by HTML.
