p.s. catalyst 10.7 beta just popped to those interested

So you need an ATI card?


- steelman1991 - 2010-07-26

No. Some Nvidia cards are also compatible.


- Sam.Nazarko - 2010-07-26

any card doing uvd/uvd+/uvd2. So Nvidia/ATI really


- nevcairiel - 2010-07-26

"UVD" is a ATI specific name.

h264 DXVA decoding is supported as of VP2 for NVIDIA (G92 and up).

Check wikipedia on what cards support VP2/VP3/VP4 for NVIDIA, or UVD/UVD+/UVD2 for ATI.

While newer Intel cards theoretically support DXVA h.264 and VC-1 offloading as well, its currently not supported by XBMC.

Works flawlessly on my nvidia G200 based card (GTX 260), fwiw. Smile

Thanks Smile

Are there plans to ad DXVA2 support in XBMC for Intel IGP?

I've got a Tranquil PC iXL media pc which has an Intel Core i3-530 with the onchip IGP, DXVA2 is working flawlessly in Boxee and MPC-HC.

I prefer the interface of XBMC, I'm not too keen on Boxee's "social networking" / interface for browsing movies/tv series (plus my remote doesnt work well with Boxee) but may have to stick with it until Intel support is (hopefully) added to XBMC.

Cheers
Nick

Yeah, I would really love to use DXVA with my Intel GPU, tried with DSPlayer but it never wants to run smoothly.


- CrystalP - 2010-07-28

No Windows dev has an Intel i3/5/7 box. Also, last I checked Intel doesn't use the standard interfaces for full video acceleration.


- SlaveUnit - 2010-07-28

If you have an intel i3/5/7 do you really even need DXVA? I would only guess maybe for interlaced HD material?


- nevcairiel - 2010-07-28

The point isn't only about capability to render, but power saving as well. Letting the GPU logic handle it is by far more efficient.

But yeah, any i3 and up out on the market should be able to software decode 1080p.
The real advantage would be for mobile systems where power saving is even more an issue. Also they could have a Intel 4500 GPU and not coupled with an i3 but a slower CPU.

The Intel DXVA interfaces are different, not completely, but different enough to cause trouble and not be supported out of the box. I guess all it requires is a dev with a intel box.


- SlaveUnit - 2010-07-28

Good point. I didn't really think of power consumption on mobile devices or even at home for that matter.

Hi,

which Build do you recommend fpr Win7 using an ATI HD5670 with Catalyst 10.6 and Full DXVA Support?


- brownn - 2010-07-28

My i3 does render 1080p content without struggling, but as nevcairiel stated...its the power consumption im interested in Smile When playing 1080p content without DXVA my CPU usage is about 40% and power usage goes to 73W where as with DVXA CPU usage is 15% or lower with the power usage of 28-30W

Thanks, so the Dharma builds do also support DXVA, or only the "Trunk" ones?
