NVIDIA AVC 264 accell in drivers - any beta/rumors for 7800GTX???

[Mei]

Currently, latest NVIDIA PureVideo software using up-to-date WMP10 can handle hardware decompression of 1920x1080x32 WMV9 HD @ 30-40% of CPU usage on an Athlon 64 @ 1GHz (C&Q Enabled).

DVD is @ 10-20%...

So I think the PureVideo hardware is really working, but in fact it needs to be used by an DirectX VA compliant software. (for WMV9 HD perhaps only WMP10 makes it working)

great news thx!

tough afaik till now there is no avc decoder available useable with nvidia's gpu
edit2: a list of potential avc decoders being able to use the gpu:
http://www.nzone.com/object/nzone_purevideo_requirements.html

CyberLink PowerDVD™ with H.264 (AVC) and AAC Pack
InterVideo® WinDVD®
Nero® ShowTime

i cant check the cyberlink avc pack, cause there simply is no download available for testing it
intervideo's windvd includes a videosoft avc decoder from 2004 which surely doesnt support the nvidia gpu
nero is currently updating its trial packages (100mb bloatware! why nero???)


edit: seems they now also updated the product list which tells what cards support avc gpu decoding:
http://www.nvidia.com/page/purevideo_support.html

[BetaBoy]

Define PureVideo's role in H.264 CPU vs. GPU as I see no mention. Anyone?

[bond]

threads merged

[BetaBoy]

thx bond... I see they are updating it to specify GPU.

[travisbell]

So does anyone have any performance comparisons yet?

[FFWD]

I'm interested too, here's a reviewers guide :

(please ignore nvidia marketing talk)

[Schrade]

It's interesting that they've changed the specs on PureVideo. Does it no longer support older nVIDIA cards?

[Sharktooth]

So does anyone have any performance comparisons yet?no, coz there are no available decoders that support it.

Does it no longer support older nVIDIA cards?Here's (http://www.nvidia.com/page/purevideo_support.html) a list of supported PureVideo features. For software MPEG-2 postprocessing any DirectX 8.0 videocard will do (incl. ATi's). Most GeForce 6 and 7 series videocards support H.264 hardware decoding acceleration.

no, coz there are no available decoders that support it.http://www.cyberlink.com/oem/nVidia/0602/enu/index.jsp ;)

Nero ShowTime and InterVideo WinDVD will be next.

[tomos]

cant wait for this to come out can bump up the bitrate in my encodes then :)

this, and when coreavc goes smp = the daddy!

[Ice =A=]

@FFWD:
That PowerDVD description does not necessarily indicate that h264 acceleration through purevideo is supported yet. In fact, that version is available for quite some time now.

@FFWD:
That PowerDVD description does not necessarily indicate that h264 acceleration through purevideo is supported yet. In fact, that version is available for quite some time now.on the site FFWD linked to it says:
Note: The NVIDIA H.264 decoder acceleration requires a GeForce 6 or GeForce 7 Series graphics card and NVIDIA ForceWare 84.12 or greater software.
so i am pretty sure it supports the nvidia gpu already

also cyberlink already offers a decoder able to use the ati gpu, i guess they are simply the most advanced ones atm in this gpu acceleration field

the bad thing simply is that there is no trial download available :(
eg i would love to add the cyberlink decoder to my decoder comparison

[DanielSun]

Bond,why didn't you include CoreAVC in your decoder comparison?

[BetaBoy]

Bond,why didn't you include CoreAVC in your decoder comparison?
I am sure he will once we publically release it after March 15.

[FFWD]

I am sure he will once we publically release it after March 15.You're announcing AVC GPU accelleration @ CeBit (9 - 15 March 2006)?

[Kostarum Rex Persia]

BetaBoy, CoreAVC decoder will be official version 1.0 or not?

[DanielSun]

Betaboy,Does CoreAVC use GPU accelleration to achieve such low cpu usage?
Does it use purevideo h.264 accelleration API or not?
What about ATI cards?( I only have NV cards)

CPU/software only.... and I cannot comment on anything GPU related at this time.

[DanielSun]

No kidding！？

That is Amazing！！！

I am totally shocked by this low-cpu-usage thing！

Great work！

[Blue_MiSfit]

Yeah.. CoreAVC pretty much pwns the house.

I tried out the apple HD gallery the other day by remuxing the mov to mkv and forcing coreavc. 30% cpu utalization for 1080p at full speed playback whereas quicktime could not even play 15fps.

awesome. im buying it :)

[Ice =A=]

@bond:
Good point that, I missed that last line... :(
However, the only PowerDVD trial version to download is from last year, and they hardly could have had that h264 hardware support back then... Strange...

eg i am absolutely not sure how much this acceleration will bring with older nvidia cards like the 6600's

also a weak avc decoder with gpu support might be still slower than a good avc decoder without gpu support (someone reported such results with cyberlink and the ati gpu vs. coreavc)

[DanielSun]

Well let's hope for CoreAVC adding GPU support in public version,and that competition will be end before it begins~

[sjchmura]

So if we have Nero 6.6 will this work with the 84 drivers or do we need to buy the NEW windvd (I have 5.0 OEM) or PowerDVD from cyberlink?

[bond]

powerdvd alone also doesnt support it, you need to buy the extra avc pack for it

[Adub]

How messed up is that? Personally the only software that I will buy will be the CoreAVC public version. I use MPC for everything, and if that doesn't work I use VLC. Why buy that crap software if there are almost always free alterantives:)

[Oline 61]

Okay, I have a GeForce 6600GT. What do I have to do to get h264 acceleration working? Do I just download the driver? I already have PureVideo DVD Decoder. What other software will I need?

[FFWD]

Why buy that crap software if there are almost always free alterantives:)I already own Nero 7, so I'm hoping for a free update around CeBit time..

I have Nero 6 with ShowTime, does that mean that it will work for me?

All latest versions for Nero 6 Burning Rom and NeroVision BTW.

[bond]

Oline 61

- if you have the agp version of your card it wont support avc
- nero doesnt seem to include gpu support atm (guessing)

[Oline 61]

But that page said that showtime supported it. I guess that must be a future prospect. I have PCI-E so I may try it anyway.

[FFWD]

Oline 61

- if you have the agp version of your card it wont support avcThe 6600GT AGP supports (http://www.nvidia.com/page/purevideo_support.html) H.264 Decode Acceleration

[bond]

The 6600GT AGP supports (http://www.nvidia.com/page/purevideo_support.html) H.264 Decode Accelerationups indeed, i mixed up 6800 with 6600 :devil:

[dragongodz]

a small review/test of Nvidia h264 decoding in french.

and as the link at the end of that says Nero showtime2 version now available in Nero 7.
http://www.nero.com/enu/NVidia.php

[Oline 61]

I take it that ShowTime from Nero 6 will never see this update?
That's a shame, 6 was so much better than 7.

[dragongodz]

I take it that ShowTime from Nero 6 will never see this update?
since Nero ,as with any company, would obviously want people to buy and/or upgrade to the latest version i doubt it will be in showtime(1) aswell.

That's a shame, 6 was so much better than 7.
the advantage of Nero 6 was it was split in bundles so you didnt have to download everything if you didnt want it. as such i havent even bothered to look at the trial version for 7 since its a 108mb download.

[BetaBoy]

The question is... (or maybe I have missed this somewhere) what actual AVC profile accelerations does it do?

[bond]

The question is... (or maybe I have missed this somewhere) what actual AVC profile accelerations does it do?afaik the acceleration isnt profile-related but feature related, like for example cabac and loop can be handled on the gpu...

[CruNcher]

so Nero decided for Nvidia's Purevideo approach

http://www.nero.com/enu/NVidia.php

wich doesn't really wonder if you compare the cards that support it vs ATI wich shoot themselves in the foot this time

[dragongodz]

CruNcher - so you missed this post i take it. ;)

[lexor]

well I sure hope that NV's implementation of h264 acceleration is better than their mpeg2 acceleration. Playing a DVD with PureVideo in WMP10 is the same CPU usage as playing that DVD in MPC without PureVideo. I'm so glad I got to test it out at work for free before buying it for myself.

[Mei]

I think your WMP10 wasn't patched in order to use DirectX VA... On my Athlon 64 3200+ using GeForce 6150 Integrated GPU, I have an average CPU usage of 20% with the CPU at 1GHz (C'n'Q activated).

Also, the PureVideo codec is usable by any DirectShow compliant application as well as acceleration is usable by any DirectX VA application...

DirectX VA 2.0 will had H264/VC1 acceleration to the actual H261/H263/WMV ...

there is a patch for WMP10? why wouldn't NV tell that on their page, how would I have known that if I didn't ask here?

as for performance I get 20% but at 2.2Ghz A64 and 6600gt in both WMP10 and MPC.

[FFWD]

FFWD says true.
