Internet & Networking Despite the recent interest in adopting HTML5's video tag, there is still one major problem: there is no mandated standard video codec for the video tag. The two main contestants are the proprietary and patended h264, and the open and free Theora. In a comment on an LWN.net article about this problematic situation, LWN reader Trelane posted an email exchange he had with MPEG-LA, which should further cement Theora as the obvious choice.

In video hardware, programmable pixel shaders can be used to support hardware acceleration of video.

Another possible method is using GPGPU (General-Purpose Computing on Graphics Processing Units).

Hardware accelerated video decoding using the Theora codec is therefore quite possible on some GPUs.

It is certainly possible on many desktop GPUs, but that doesn't matter much. Desktop CPUs can already do it in software just fine. The real problem is mobile devices. The iPhone simply can't handle video decoding in software. And the iPhone's GPU doesn't have nearly the generic computing capability that a desktop GPU has.

This is nowhere near enough of a reason to impose a patented codec on the web and thereby rip off everybody who does not own an iPhone.

Fortunately, phones are a very short life item. Perhaps the unlucky iPhone owners who have been dudded by Apple's attempted lock-in will be aware enough buy a Nokia smartphone with maemo and android next time.
