Do you care about the H.264 hardware decoding function in the ATIdisplay cards?

Are you sure ATi's DXVA implementation works on H.264 videos? As I
understood it, it worked only on WMV HD (aka VC-1) format, as indicated by the "WMV Acceleration" checkbox in CCC. Are you sure you didn't just install a more efficient software codec when you installed the bundle? :-) For H.264, the software implementation in the CoreAVC codec is fast enough on my Athlon X2 2.2 GHz. I get 20% CPU utilization with 720p 25fps videos, according to Task Manager's method, which would be equivalent to 40% utilization on a single-core CPU. The number did not change when I switched from ATI X1900XT to Geforce 285.

Whoops. I was confusing H.264 with WMV HD (VC-1). Silly me. I don't believe
I have any true H.264 content on my machine. I will download the CODEC you linked below and see what kind of CPU utilization I get on my FX-53. Know any place to download demo H.264 content? As far as WMV DXVA acceleration goes, it was always enabled from the CCC perspective.

Most Quicktime HD videos are H.264. If you rename the file extension from
*.mov to *.hdmov, the file will play with the system's preferred H.264 decoder in lieu of the Quicktime decoder. For example, name the following 720p trailer as *.hdmov when the "Save As" dialog box comes up (mind the linebreaks): http://moviesmovies.ign.com/movies/v...40108_qthd.mov When Media Player Classic plays the resulting file on my system, it shows CoreAVC as the decoder used. Since you just installed a codec pack, FFDShow may be the current default H.264 decoder. Both Gamevideos.com and Gametrailers.com are good places to download high-def H.264 content. -- "War is the continuation of politics by other means.

Do you care about the H.264 hardware decoding function in the ATI display cards?
Just installed CoreAVC v1.9.5.0 in the link (previously I was running
v1.8.5.0). Looks like they put in an option for CUDA acceleration. For what it's worth, CPU utilization dropped by half compared to the numbers I gave below. -- "War is the continuation of politics by other means.

Do you care about the H.264 hardware decoding function in the ATI display cards?
I downloaded the Zelda Film trailer and first tried it using Apple's
QuickTime decoder. The framerate was terrible while CPU is pegged at 100%. I then viewed the same H.264 file using libavcodec (from ffdshow) and the framerate was perfect with CPU utilization ranging from 50% to 70%. I've since removed QuickTime Alternative (which was providing Apple's decoder) and am using ffdshow exclusively for .mov and .hdmov extensions. Also, it turns out R600 and later based ATI cards do support DXVA with H.264. From http://nunnally.ahmygoddess.net/watc...os-using-dxva/, here are the ATI and NVidia cards which support DXVA with H.264 ATI:- RadeonT HD 3800 Series, RadeonT HD 3600 Series, RadeonT HD 3400 Series, RadeonT HD 2600 Series, RadeonT HD 2400 Series, Mobility RadeonT HD 3600 Series, Mobility RadeonT HD 3400 Series, Mobility RadeonT HD 2600 Series, Mobility RadeonT HD 2400 Series, Mobility RadeonT HD 2300 Series, Radeon 780G integrated chipset - UVD 2 + AVP 2 (with Phenom only),Radeon HD 4xxx HD Series - UVD 2 + AVP 2. nVidia:- All GeForce 8xxx cards and IGPs except GeForce 8800GTS/GTX with G80 core. All GeForce 9xxx cards and IGPs. All GeForce 2xx cards. Unfortunately, my R580 based X1900XTX won't cut it. Interstingly enough though, DXVA checker does report that H.264 DXVA with AVIVO is available and enabled. It's probably just exposed by the driver even though the hardware can't take advantage of it.

It's surprisingly robust. Unfortunately, my R580 based X1900XTX won't cut it. Interstingly enough though, DXVA checker does report that H.264 DXVA with AVIVO is available and enabled. It's probably just exposed by the driver even though the hardware can't take advantage of it. I wonder if this is related to the AVIVO Video Converter being broken in Vista 64? -- "War is the continuation of politics by other means.

Correct, the topic has deviated pretty far from your original post.
To answer your question, I don't care about H.264 hardware decoding, because well-optimized software decoding with CoreAVC is fast enough (even without invoking CUDA on my Geforce 285). -- "War is the continuation of politics by other means.
