DS Misc > Supercard Movies on DS Fullscreen

#56919 - Feri - Wed Oct 12, 2005 7:23 am

Is there anything out for the Supercard to view Fullscreen Videos on Supercard? 256x196? Moonshell doesnt work... Is there something else out?

ps. why isnt it possible to make a good videoplayer for the DS??? I mean there were a lot PSone Games with Videos and the PSX only had 33mhz. And for Nokia Ngage there is even a Fullscreen DivX+Xvid Player with mp3 Sound. I think the DS has more HArdware Power than the Ngage does.

I found a Webpage where u can download Video for the DS which are realy amazing! Its made with a mpeg4 Codec, but its only for developers. Thats so cool a 27 minutes Anime Episode is only 16 MB! Imagine how cool it would be if u would encode it with higher bitrates...
u can see the videos here: http://www.ds-video.com/

ngage has a faster cpu, and a smaller resolution screen (thus less data to display/decode), than NDS.

since when did the ngage have a more powerful cpu? one of its failings was that it was underpowered.

playstation could do videos cos it has cds therefore the videos needed little compression and were easy to play.

N-Gage was underpowered for 3D games, but it was just fine for 2D games. The N-Gage CPU is faster than that of the DS, but there is no specialized 3D rasterization hardware on the N-Gage. Movie decoding generally runs on the CPU, not the video chip, unless you have one of those new DirectX 9 cards that can do an inverse DCT inside a pixel shader.

The videos still used MPEG-like compression and were decoded through a hardware-accelerated "MDEC" coprocessor. This is the technique that the Play-Yan product uses.

The Caimans codec implement mpeg4 standard features, but it's not mpeg4 compatible, mind you.

I haven't looked at the demos (no way to run them on my DS yet), but by the sounds of it, it seems more efficient than vanilla MPEG-4, at DS specs.

The thing is, creating such optimized video codecs is a hefty task. Caimans is a commercial product. I don't know how much the licensing fees cost (when there are no visible prices on the website, it surely ain't cheap), but I estimate something between 2K to 5K, per title, with options for royalty-based licensing and volume licensing.

It's just a matter of some talented homebrew coder with loads of time on his/her hands get interested in such idea... whenever that happens...

The nGage has a 104MHz ARM4t cpu. Just a little bit faster than the ARM9 in the DS, but the 4T is a thumb-only cpu, afaik... whereas the DS ARM9 is a full arm/thumb cpu.

the demos on this site is pretty amazing...
