Google funds TheorARM

Quote:
Video decode is a pretty CPU intensive task. In order to fulfill the dream of being able to work on every device some painstaking effort is required. The complexity of Theora is considerably less than that of many of its peers; other codecs often require dedicated hardware in devices to help achieve performance targets, but with careful coding Theora can be made to run without this. In fact, on desktop/laptops realtime decode can be managed by an embedded Java player (such as the excellent free Cortado), enabling video playback on browsers still waiting to have video tag support added. For the increasing range of PDAs, phones, netbooks, web tablets and media players out there though, this isnít an option. Rather than having typical power hungry desktop processors in, these devices tend to be built using the much more frugal ARM processors. While these have increased in power in leaps and bounds in recent years, they still canít compare with their larger cousins for raw computational grunt. These ARM based devices represent the single biggest class of devices still needing work for decent Theora playback. Any efficiency savings we can make feed back directly into being able to cope with larger screen sizes or giving longer battery life.

This is where Google's grant comes in - by helping fund the development of TheorARM (a free optimised ARM version of Theora), they are helping to hasten the day when video works everywhere on the web, for everyone. Thatís got to be something to be pleased about. And now you can flick forward to the next blog post.

Enjoy !
