Nintendo 3DS GPU Revealed 133

An anonymous reader writes "The GPU for the Nintendo 3DS has just been revealed, and it's not made by Nvidia, ATI, or even Imagination Technologies. Instead, Nintendo has signed up Japanese startup Digital Media Professionals (DMP) in a deal that sees the company's PICA200 chip churning out the 3-D visuals. For the first time in Nintendo's history, the 3DS will feature a GPU with programmable shaders, rather than a fixed-function pipeline, meaning the 3DS is more graphically versatile than the Wii. Among the PICA200's features are 2x anti-aliasing, per-pixel lighting, subdivision primitives, and soft shadows. As well as featuring DMP's own 'Maestro' extensions, the PICA200 also fully supports OpenGL ES 1.1. The architecture supports four programmable vertex units and up to four pixel pipelines."

divx and xvid are slightly modified version of mp4. (reference - "Methods described in MPEG-4 part 2 (MPEG-4 SP/ASP) are used by codecs such as DivX, Xvid, Nero Digital, 3ivx and by Quicktime 6, and methods described in MPEG-4 part 10 (MPEG-4 AVC/H.264) are used by the x264 codec, by Nero Digital AVC, by Quicktime 7, and by next-gen DVD formats like HD DVD and Blu-ray Disc.").

You should check out VLC player for a fast good playback experience. Quicktime is what most people try to use to play mp4 files, and, yes its a little slow on most computers.

I was surprised when this happened, but I can appreciate that, ultimately, it's a legacy format. Apparently, the AVI implementation is very convoluted to keep up with new features. Here's a selected quote from their release blog: "It does not support modern container features like chapters, muxed-in subtitles, variable framerate video, or out of order frame display....The code has not been actively maintained since 2005. Keeping it in the library while implementing new features means a very convoluted data pipeline, full of conditionals that make the code more difficult to read and maintain, and make output harder to predict. As such, it is now gone. It is not coming back, and good riddance." (sadly there didnt seem to be a permalink to the whole article - here's the current news page).

As such, I've moved on and figured out which flavor of mpeg-4 works best for me; and I'm happier with the improved picture quality as a result.
