So far, the Dharma nightlies have DXVA support for me..

I'm not getting this working here.

System: AMD Phenom 9850, 4GB DDR2, ATI HD4200 IGP
OS: Windows 7 Ultimate x64
No codec's installed, Ati CCC 10.7, xbmc-r32268-Dharma.exe, DXVA enabled.

h264 is working great, no problems, low cpu (1-5%) but playing vc1 is a nightmare. Either I get a green rash on my screen or playback stutters. This differs which vc1 file i use. When trying older drivers my sytem has a BSOD or just a black screen. Are there others out there having the same issues? Im going to try x86 tomorrow, maybe that makes a difference.

Has anyone actually done a power usage comparison between using DXVA and software? Cause with CUDA there is virtually no difference, I think only 'proper' hardware like the CrystalHD will save power. My popcorn hour can decode 48mbit 1080p material without breaking 10 watts.

My other PC also has the same problem with VC1. See link below for debug info.

5 posts earlier in this same thread:

Hi, I have a similar problem with VC-1 content, high CPU usage + stutters, although it is apparently being played back via DXVA. Content is all mkv rips of blu or hd-dvd's, video is raw off the disc. Havn't seen the green rash myself although I'll try a few more and report back.

System: Intel E8400 2GB DDR2 ATI5770 PCI-E
OS: Windows 7 Ultimate x86
ATi CCC 10.7 xbmc-r32268, DXVA, Sync To Refresh, Adjust Refresh enabled.

Hey Freddo,

I'm about to give up because I can't get DXVA VC1 running with ANY software that supports is. I tried MPC-HC, VLC Player and FFDShow filtering and neither of them is capable of using DXVA on any of my ATI cards. And if I'm googling around, it seems we're not the only ones having trouble with ATI, CCC and DXVA.

I'm about to order a Zotac GT220 ZONE or a Zotac GT240 ZONE (Nvidia chipset, VP4 DXVA support and passive cooling) because it's driving me nuts Shocked.

I sometimes wonder what you guys do to these ATI cards and set-ups Big Grin. I'm currently running a Win7 x86 with ATI HD5450 card, CCC 10.7 xbmc-r32268 and it will play anything I throw at it virtually flawlessly, here's a screenshot of VC1 with dxva

I really don't know. Did a fresh install, latest drivers, tried x86 instead of x64 done it all.

EDIT: a friend of mine is bringing his HD5550 over tomorrow. Will test what it does and report back.

hd4670 1gb ccc 10.7 xbmc rev 32268 flawless! NodWink

have the same problem with vc-1 ... system is a amd 6000+ (2x 3 ghz) and a nvidia 8600gts....h.264 works fine, but vc-1 is not gpu encoded and and the cpu works at 70% on 1080p

That's correct because your GPU is too old.. No offense Wink

http://en.wikipedia.org/wiki/Nvidia_PureVideo

As you can see there your GPU is a VP2/VDPAU Feature set A. This means you GPU is'nt capable of full accelerated VC1 decoding:

Feature Set A
Complete acceleration for H.264
Partial acceleration for MPEG-1, MPEG-2, VC-1/WMV9

Or buy an Nvidia 210 ($30-$40) or GT220 ($80) GPU...

Devourer did you ever resolve your issue with the IGP, or was that unsupported as well?
