NV and H.264 acceleration ?

I bought an AGP Radeon X1600 Pro ( Sapphire ) and the WMV HD decoding works perfectly without any audio sync issues on my lowly Athlon 64 2800. H264 decoding at 720p works really well as well though the CPU utilisation reduction isn't as great as nVidia's. I read here http://www.digit-life.com/articles2/video/g71-part5.html
that ATi are reworking their H264 support to improve things.

can you both test with the above trailer?
720p is ok even without acceleration, but 1080p is no go... so if you can post CPU utilisation (and what cpu) ....

nVidia H264
I can do some testing tonight. The X1600 doesn't do 1080p. If I look at an intensive 720p trailer like "Basic Instinct 2" 720p QuickTime HD, The X1600 reduces CPU utilisation by around 10%, so the CPU utilisation on my Athlon 64 2800+ ( 1.8 GHz ) was around 50-90% in software mode and 50-70% in hardware mode. In comparison, the nVidia card reduced it all the way down to around 40-60% though the image was garbled.
Also, the ATi card's H264 decode jerks when there's an intense scene and this is with the same 720p clip. In comparison, the nVidia H264 produces a much smoother image. It looks fluid despite being garbled as some things can be made out, but I can't tell for sure.
[EDIT] I've tried "The Greatest Game" Nero trailer before. It hits 100% even with nVidia aceleration at times.

can you post results from " the great movie" (link is above)?Zark said:
Underworld plays smooth (although 30% CPu load ) even on P4-3.0, 1080p is the problem...
Oh dear.
nVidia have now updated their PureVideo support page to claim that no AGP geforce 6 or 7 series card supports WMV HD:
http://www.nvidia.com/page/purevideo_support.html
In case they mess about with again:
They've also closed the support ticket for WMV HD acceleration not working.

nVidia H264 finally works on the AGP 6600 GT
H264 decoding works properly with Forceware 91.28. They've fixed it at last.
Also, these drivers come with ATi style smearing/ghosting technology, which by default is turned off. These options are "Noise reduction" and "Edge enhancement"

I don't think so.
All 7 series GPU's have Purevideo with WMV-HD decode built-in.
Even 7800 GS (it's just a PCI-Express G70 GPU, cut-down and bridged back to AGP8x with the BR02 chip).
http://www.nvidia.com/object/IO_30459.html (PDF)
You are probably confusing them with NV40/NV45 (AGP and PCIe versions of 6800 Ultra and 6800 GT, respectively), that featured Purevideo for MPEG-2 only, not WMV-HD.
Nope. Not confusing anything with anything, sorry.
Look at the page. It used to be there (i.e. listed as supported), now it's not (those particular table rows are actually commented out in the source of the page). Also, there used to be open bugs about it not working properly that are now closed and unresolved. WMV decode was only ever semi-functional in some driver releases for the 'supported' AGP cards, and the references to it ever being supported are removed from the Purevideo overview page (also including the 6600 and 7800GS, which should not have been impacted by the reportedly broken purevideo in NV40).
Compare the US chart posted/linked above to the (yet to be history-revised) UK site.

Something must be wrong, because i happen to own a 6600 AGP8x, and purevideo works perfectly (WMV and H.264).
BTW, i see that 7800 GS AGP8x is supporting H.264 and WMV9 in high definition on that link you just gave us.
Only QuadroFX AGP doesn't support Purevideo, and that is normal...

Works perfectly as in 'plays just fine', or works perfectly as in 'has markedly lower CPU usage with the WMV hw-decode patch and a supported H.264 codec respectively'?INKster said:
If the latter, could you provide your config and some benchmarks?
Edit:
Err... That's my point. They have explicitly *removed* that information from the main US page within the last couple of days. They used to say it was supported, but now they don't. Or do you think they commented out those sections of the page by accident?INKster said:

Well, it's not one of my primary rigs, and it's used basically as a home-made Media Center.
It's has a relatively old "Barton" 2600+ at stock speed (1.92 GHz), a Gigabyte 6600 AGP8x (256MB, passive cooled) and 768 MB of DDR333 single-channel.
FW 84.43, WinXP SP2 Pro, etc.
I like it because it's virtually silent without using expensive watercooling, and it stays cool with just minor mods.
I detected CPU utilization as low as 50~60% when playing the Terminator 2 trailer encoded in WMV-HD (available at microsoft's website), when before activating purevideo i had spikes of 80 to 90%.
edit
My card has a NV43, rev A4.
Is it possible that it was featured on a older driver, then removed/toned down because of too many problems with most cards (like ActiveArmour on NF4) ?
