DXVA specifications for G45 chipset?

DXVA specifications for G45 chipset?

Hello,

I'm one of the authors of "Media Player Classic - Homecinema" (http://sourceforge.net/projects/mpc-hc/). This open source playeralready supportDXVA bitstream decodingwith ATI and nVidia graphics cards.

We plan to add support for Intel G45, but we have to following problem : standard Gui for H264 bitstream decoder (DXVA2_ModeH264_E and DXVA2_ModeH264_F) didn't seems to be implemented on G45. Furthermore, calls to function GetDecoderDeviceGuids on interface IDirectXVideoDecoderService return 2 Gui that did not appears in Microsoft DXVA specifications : BCC5DB6D-A2B6-4AF0-ACE4-ADB1F787BC89 and 604F8E68-4951-4C54-88FE-ABD25C15B3D6. I guess one of the is for VC1, and the other for H264 bitstream decoder.

So my question is :does Intel use a specific protocol for bitstream decoder, and if so is it possible to have the specifications?

Thanks

Casimir

I'll look into this and let you know what I find.

It took me a couple of days as I had some dialog with the media engineers. Essentially, G45 doesn't support the standard GUIDs for VC1 or AVC, and the private specifications are not publicly available.

It reminds me of a philosophical question - if an interfacehas no spec and no one is able to use it,does it truly exist?

Chris

Thanks a lot Chris for your efforts to answer my question. I hope Intel will change his mind and publish this specifications in the future.

Casimir

Heh, me too. I'm continuing to push for this internally. We'll see how far I get.

I am coming across this thread after a longer research on the web: I would be very interested in getting all technical information about how to use hardware decoding of the G45 / X4500HD platforms in custom software, i.e. is it fully DXVA compliant (1.0 and/or 2.0)? Is there an other (Intel) API for accessing these features? Is the API publicly available? If not (as it seems), how am I able to get access to this information?

Thank you. Marco

Thank you for your reply. From the pdf file you referenced (or the product brief of dg45fc, which I already read), I am unable to answer my questions, i.e. the document only says that DirectX 10 is supported, and some end-user software is included, which is related to media processing and playback. On the other hand, the discussion in this thread points out that some interfaces for hardware decoding are not public, are they?

I would like to add, that X4500HD drivers for Windows XP seams to not support H264 HW Acceleration at all.
I have tried all the accelerated codecs: TotalMedia, PowerDVD, WinDVD, etc, and they are not able to unload CPU from decoding in Windows XP, while they can in Vista.
Anyone can confirm this?

Intel follows the HDCP rules more strictly than ATI/Nvidia. Windows XP hardware acceleration with HD video aren't supported because of that. They don't like bending rules.

What does it means? HDCP is supported by the chipset. If the driver conforms to PAVP, the HW accelerationcan be used on any operating System (linux inclusive).
Can you calirfy your statement?

Also, I would like to restate the first question: seen there is no way to write down a custom codecimplementation due a lack of specifications, is there any commercial codec supporting DXVA bitstreaming acceleration (both for H264 and VC-1), so a user canfully take advantage of the investment inits G45-based motherboard?
Thanks!

Doh! We were supposed to sell them? I knew we forgot something. :)

There are commercial players in the market that use the HW acceleration provided by the chipset. Some OEMs even bundle them on the systems that they sell. The problem raised by this thread is that the specs are not available to the general developers in the world so they can also write these type of applications. While several of us internally are strving to get these specs released, the current direction is to keep them under lock and key.It's not a big conspiracy; it's simply some of management's fear that content protection schemes could be broken by releasing these specs. I don't believe that to be the case, but as soon as the words "liability" and "lawsuits" get dropped, people get very hesitant to release anything to the public.

Thanks for testing!

That's a very interesting aspect. We know that nVidia and ATI cards to support GPU accelerated for BluRay on WinXP and we do know it doesn't work with intel cards. Archibal once remarked that XP doesn't offer the software stack that allowed decoding of copy protected content without interception and intel is afraid of any potential uncertainties regarding law matters. Thus not supporting XP. This argument has been repeated in this thread.

Now it seems: Not only the GPU assisted playback of copy protected streams is NOT supported on WinXP, but also the entire GPU assisted playback API for H.264/MPEG4-AVC streams or decoding stages is either broken or not available in WinXP! That's quite a difference!

That again means intel is selling features simply not available. Intel presents a quite detailed summary of GPU assisted video decoding stages of current hardware here. This presentation suggests you get the features with Intel Clear Video Technology, which is available on Windows XP as well as Vista. This has just been proven wrong!

Intel is not only keeping the DXVA API for H.264 playback away, but also not telling which software enables these features!

I made similar experiences with hardware assisted DXVA MPEG-2 playback on intel hardware here. Maybe there is MPEG-2 hardware assisted playback somewhere with some software in some laboratory, but it doesn't seem to work with common software (that even holds for the Linux drivers: XvMC is only enabled with very particular drivers and playback software). At that time I already asked intel to make very clear: Which feature is available with which software!

As an OEM and a channel program partner I have open a support case.
It's now closed with this response: It's confirmed INTEL doesn't and won't support G45 HW Acceleration (of any type) on Windows XP.
This is a real shame since we will have plannedbuilding more than 5.000 htpc for every year, mean $100 * 5.000 = $500.000 lost for Intel Business. This is a drop in the sea of Intel Business, but adding this to many other OEM going to NVIDIA or AMD chipset, could be an interesting lost of business.
Anyway good to know we have to change m/b in our stage of designing. Very good and quick work from the support. I'm very satisfied with them, not satisfiedat all from the productdevelopment side.

Hi everyone.

I just bought a laptop with a 4500MHD graphics adapter and now I'm starting to realize it was a bad choice. I was fooled by the marketing hype Intel made about it being remarkably better than previous integrated graphics solutions from Intel, specially regarding the new HD video-decoding functions (I'm not a PC gamer). It's very frustrating to see that I can't use the hardware I bought to the fullest of its capacity because Intel has some vague problems about something that doesn't seem to affect the competition and blocks open source developers from working for free to make Intel's hardware fully enjoyed.

I really hope that this decision is reversed. And I hope you realize that I'm just an average user that has spent the last week struggling to find a way of playing some videos in his brand new computer, only to find out this thread. Argh.

Hi Agree with you it's a real shame Intel doesn't publish SW Interface to usethe HWit produces. For me this is the most strange thing I haveever met on the IT market, anyway this is confirmed.
You canhave HW acceleration in Vista only buying ArcSoft TMT ($70) or CyberLink PDVD8 ($90). They provide an accelerated codec you can use in any application (included MPC - Home Cinema and Vista Media Center).
I'm thinking there is a side agreement between Intel and this SW vendor....

Yeah, I could try that, but I won't. If I had known this would happen I would prefer to spend a little more on a laptop with dedicated graphics. I mean, when I was searching for laptops I saw some that were about $150/$200 more than the one I got, but they had better general specs, not just dedicated graphics. Spending $80 on a software video player now kinda defeats the whole purpose of having chosen this one.

P.S.: this reply seems like I'm a bit angry at you, Alex. That's not the case. I appreciate the suggestions, but I usually hate commercial video players of the likes of WinDVD and PowerDVD. I don't know ArcSoft TMT, but I'm gonna check if there's any trial available.

I have an Intel G45 and Core2 CPU I purchased for my media center, I'd like to know how who I can contact at Intel to express my displeasure regarding this deliberate and misleading advertising to state the chipset's ability to render high definition content artificially limited to not function with an OS that is still in widespread use.

I have no care or interest for HDCP, only hardware decoding of x/h264 content over the HDMI, the reason I bought this capable, yet intentionally crippled product.

I would like to add my voice to this complaint. The hardware decoding on the G45 is described at best as "adequate". The Intel driver is limited and contains no real user functionality. Add to this the lack of DXVA compliance, the hardware acceleration is poor.

I had my G45 (Foxconn G45M-S) hooked up to a 720p Panasonic plasma via Vista media centre (64 bit). I used both Vista Media Centre and PowerDVD 8 and detected many issues. Here are some of them:

  • colors are washed out (I think using HD color decoder for SD content)
  • picture very noisey - noise reduction of Intel Clear View technolgy might as well not be there as it does nothing
  • sharpness control simply adds extreme amount of picture noise which makes it unusable
  • Saturation works at wrong frequency and so creates heavy red saturation without adding true RGB saturation increase/decrease
  • Blu-ray movies looks quite "flat" and lifeless - picture worse than SD TV content
  • Default for Intel G45 driver (hookup via HDMI) defaults to 30% overscan
  • Adding overscan creates immense amount of picture noise and so forced to underscan (Horizontal 70 and vertical 70 on my set)
  • Not to mention - it only rates 3.0 on the vista Graphics and 3.1 Gaming Graphics performance tests.

In contrast, I installed an ATI 3650 and all the above problems disappear and scores 4.8 on the graphics tests. The ATI card was in my 1st media center and I built a 2nd media centre around the G45 chipset after reading Intels hardware decoding claims. After seeing the picture quality and driver limitations, I wonder how Intel can throw these wild statements about how wonderful and capable the G45 graphics chipset is - especially in the statements for its use in a media centre.

Persoanlly, I believe it can't reproduce a DVD correctly (contrast, brightness, contrast, etc) let alone any HD content. I think Intel needs to take a look at ATI (and Nvidia) and see how good DVDs and bluray look - possiblly consult some audiophiles and videophiles - if they this chipset may have been spectacular not lack lustre.

Hope a driver update fixes all the above issues and gives the same options as ATI Catalyst Control Centre - but i will hold my breathe while i wait......

Thanks smart-ass. I think you missed the point. Wen was speed a factor or ever mentioned in anything i stated in my post?

Neither ATI nor Intel grahics chipsets are designed for gaming and so neither is faster than the other in answer your strange statement.

Both are suppoosed to decode Blu-ray using GPU hardware decoding - that's it!!!

The point was (which I thought was quite clear and obvious if you had read my post...) and that is:

  • my $60 3450 ATI graphics card decodes blu-ray and DVD correctly.
  • The G45 doesn'tdecodes blu-ray and DVD correctly.

Also, the G45 driver doesn't have any functions that actually work correctly on video such as sharpness or color.

I wasn't expecing a gaming machine chipset - just one that delivers what it promises. I guess in hindsite, Intel never stated that it decoded HD and DVD well, just that could decode it.

Make up your mind.You previouslystated the ATI card was HD 3650, which is in fact ATI's mid-range part in the HD 3000 series, and is hugely more capable than HD 3450. His point was a lot more valid;NO integrated graphics solution on the market at any given time can remotelycompete in any category witha discrete $60.00 mid-range GPU. Its guaranteed that a discrete $60.00 GPU will be far superior to any IGP solution that is within one generation of it, so your comparison is meaningless if not dumb.

I have the exact same experience. Bought an Asus P5QE-EM motherboard with integrated x4500HD graphics, connected it via HDMI to my Samsung 40. Tried updating to the latest graphuics driver but the result is still the same: 30% overscan and crappy picture quality (actually slightly worse than my old optiplex GX520 with Intel GMA950!!!!).
Any budget Nvidia or AMD card would do a better job I think.

Greetings!

I would also like to voice my disappointment about the current state of GPU accelerated video playback on Intels GMA chips. I recently bought a Sony Vaio TT 11.1" subnotebook equipped with a BluRay drive, an Intel GMA 4500MHD as well as HDMI (and then retrofitted with an Intel X18-M SSD to make it even more expensive ;) ). Maybe I did not inform myself to well before purchase, but I thought that piece of GPU silicon would do DXVA in any case (at the time of purchase I did not know anything about DXVA "1" and "2" versions).

So, I would love Intel to make DXVA1 available in their Windows XP drivers, as the operating system is in my opinion the perfect subnotebook solution. If that would be the case, I could probably use the device for BluRay playback, because without GPU assist it is just not powerful enough (it's close, but still there are stutters, CPU is Intel C2D SU9600).

Please, make DXVA1 available for *all* GMA3/4 series IGPs to use this in Windows XP, either with Software like PowerDVD or better even Media Player Classic Home Cinema!

Thank you.
