yep it's the only one that got privatized the other Ion demos are still open lol why do they make such a secret of it's status suddenly it looked ok :)

Have you still got a copy in your browser cache?

[CruNcher]

unfortunately not they demoed the flash GPU Decoding with the 720p StartTrek and Harry Potter Trailer inside Firefox on Windows 7 on the HP Mini 311 Netbook

From what i read it is more then that. It is basically a GPU based Flash 10, rather then just Hardware Video Acceleration.

Flash 10 already has GPU scaling and compositing, as does Silverlight.

It always crashed for me on dual-screen machines in Flash, though. The Silverlight implementation has been stable enough that we have it default on in our templates.

Flash Player 10.1 Features and Enhancements
(http://forum.doom9.org/newreply.php?do=newreply&noquote=1&p=1331013)
http://labs.adobe.com/technologies/flashplayer10/features.html#mobile
Graphics hardware acceleration

(Mobile only)
A GPU-based vector renderer replaces the software renderer on smartphones and other mobile devices, resulting in faster rendering performance for more expressive user experiences while consuming less power. Supports hardware acceleration of 3D effects, vector graphics, color transforms, alpha, device and embedded text, Saffron and surfaces.

Video hardware decoding

Flash Player 10.1 introduces hardware-based H.264 video decoding to deliver smooth, high quality video with minimal overhead across mobile devices and PCs. Using available hardware to decode video offloads tasks from the CPU to improve video playback performance, reduce system resource utilization and preserve battery life.

Why is Graphics hardware acceleration Mobile only........

"Video was removed by user"

[CruNcher]

Look @ the official Max Video posted by kieranrk it shows the same Demonstration only without harry potter Demo but includes a Gi joey 10 mbit Tegra Demo also full flash acceleration including the vector part not only video :) i wonder how that does work on the GPU when multiple websites are opened in the Webbrowser it seems though the Mozilla guys started implementing the "Focus" ideas i mentioned in some thread as being a good way of handling the heavy load in a multimedia scenario and with electrolysis coming it can be even more enhanced :)

So with the help of Nvidia and ATi Adobe seems now to have a fixed a major problem vs Silverlight and that was efficiency :D now they on par again, but as i said i really would like to know how that turns out in certain Webbrowser Flash overload scenarios we tested.

Also in the Mobile section (ARM) not everything is Tegra powered and i hope they optimized not only for Tegra but for every ARM like the A8 Cortex Neon that is widely used now too and still allows Cheaper Devices then Tegra currently does for the avg joe :)

Currently their are only 2 really mobile Devices based on Tegra APX 2500/2600 (Samsung Yepp-M1 and the Zune-HD) both are price wise to high (both running Windows CE or Mobile cores) in what capabilities they offer compared to most A8 Cortex Devices (which already come as full Android based MIDS) :)

[CruNcher]

It has arrived as a Developer Pre Release Plugin http://labs.adobe.com/downloads/flashplayer10.html ATI/Nvidia/Broadcom/Intel solutions supported currently :)

Adobe is using DXVA to accelerate Flash video playback, which means you need a GPU that properly supports DXVA2.

[CruNcher]

I highly doubt that this is true maybe though for Win7 and Vista ;)

[Keiyakusha]

I just installed new beta. Don't know about using GPU but resize not working for me anymore. Always nearest neighbor used. :(

[easy2Bcheesy]

I just don't understand why the software decoder is so awful. Even on a quad core chip, I still drop frames watching some HD content. All this effort to support hardware acceleration... can't they license CoreAVC too?

All this effort to support hardware acceleration... can't they license CoreAVC too?It's singlethreaded and for various reasons they're forced to do colorspace conversion in software. The decoder isn't particularly bad if you ignore those two.

But yeah, I suspect inertia--and perhaps also an obsession with security.

Same here that's really Evil lower CPU but therfore the whole has visually dis improved into under SD Quality :D hehe (though it's crazy that this wasn't known before the release ?)

[mark0077]

Same for me. I know many users do care but I don't care whether my cpu usage is low when watching a video for example..... just means my gpu usage is higher lol. With cpu's being so efficient who cares about a few % cpu usage difference? especially with some gpus being so power hungry once their % usage increases.

Hardware video decoders built into Nvidia and Ati GPUs are dedicated chips, separate from the rest of the GPU. They are probably about ten times more energy-efficient at video decoding than a general purpose CPU. Of course, there is some additional overhead from moving data around, but I doubt it's any worse than in CPU-based decoding. Overall, hardware decoding is much more efficient.

Postprocessing filters (denoising, deinterlacing and sharpening) executed on the GPU are more taxing, but then again, you couldn't run many of them on a CPU at the same time.

[Keiyakusha]

So, for flashplayer 10.1 beta new drivers from nvidia is needed... does scaling issue fixed with new drivers?

[lucassp]

Nope. YouTube still looks awful.

[Keiyakusha]

flash player 10.1 beta2 is out. changelog is pretty massive. also it says that scaling and some youtube stalling was fixed.
