nVIDIA PureVideo w/ H.264 acceleration?

[amdnVuser]

According to nV News (under CES Press Releases), "Cyberlink, Intervideo, and Nero will be demonstrating playback of movies encoded in H.264/MPEG-4 AVC?the next?generation format that will be used on HD DVD and Blu-ray disks?using hardware acceleration provided by NVIDIA PureVideo technology" at CES. Has anyone else heard about this? I know nVIDIA promised H.264 hardware acceleration towards the end of last year, but I hadn't really heard anything since. Comments?

I wonder if this is specific to 7-series cards...probably is

 

[dug777]

bet it is

That's what I'm thinking, too. Does anyone think the degree of performance will scale somewhat like ATI's X1xx series GPU's (i.e. X1300 or GF 7300 for 480p, X1600 or GF 7600 for 780p, X1800 or GF 7800 for 1080p)?

It shouldn't with a dedicated, discrete video processor like Nvidia claims for their PVP. If it does, it would seem suspiciously like ATI's shader solution, which of course rely's on the video cards shader pipeline rather than a discrete processor.

In either case, hardware H264 acceleration is a welcome feature for anyone whos played the Quicktime HD trailers.

So no go on the 6-series then?

My magic 8 Ball says "odds are against it"

I don't really care if it works with the 6series or not, my X2@2.5ghz has no trouble with any of the H.264 stuff I've tried so far.

What media player do you use? I've got an Opteron 170@2.6, but I still got quite a bit of stuttering/dropped frames when watching a 1080p Quicktime7 clip a while back (though a few others played fine).

Give VLC a try

BTW, what clip was it, and do you have fastwrites enabled? <---Fastwrites may mean dick to gaming, but it can make or break smooth media playback.

Well here is an unofficial copy of the press release and it look like Purevideo is coming to the Geforce 6 series :thumbsup:

Although I would wait for a more official annoucement to be sure.

Featured in NVIDIA GeForce 6 and 7 series GPUs, NVIDIA PureVideo technology allows users to experience home theater quality video on the PC with superb picture clarity and precise, vivid colors across all high-definition (HD) resolutions. High quality HD output is powered by NVIDIA PureVideo technology, whose hardware acceleration engine and advanced software algorithms enable smooth, crystal-clear playback playback of HD video, including H.264/MPEG4-AVC, Windows® Media Video 9- and MPEG 2-based footage, with minimal CPU overhead.

NICE!!! lol.....

If i were to view 1080p on my X2... would setting it on one core result in better performance?
TIA

It doesn't really say anything about the 6xxx series having H.264. They list all that yet the GeForce 6800 AGPs don't have the WMV acceleration they so proudly brandish.

From wikipedia:

PureVideo and the AGP GeForce 6800

When the 6800 first came out, NVIDIA advertised it with their new on-chip video processor dubbed PureVideo. Purevideo was claimed to decode, encode, and play several video formats while taking much of the load off the CPU. It also included some other features like advanced de-interlacing. But it's most attractive feature was hardware-assisted decoding of WMV HD, a relatively new codec.

In WMV9 playback, user and web reports have shown little if any difference between Purevideo enabled Geforces and non-Purevideo cards. To add to the confusion, NVidia has been unclear about the status of WMV9-playback and PureVideo. NVidia has admitted (in private communications to vendors) that the NV40/NV45's PureVideo unit may be missing the WMV9 component. But in public, NVIDIA has merely acknowledged the absence of WMV9 support in its driver-set, promising the functionality would be added to a future release.

On all other members of the Geforce 6 family (the 6200, 6600, PCIe 6800/6800LE), WMV9 testing has demonstrated a marked improvement in CPU-utilization over the baseline AGP 6800. The prolonged silence of NVidia, after their public promise of updated drivers, and test evidence gathered by users has led the user community to conclude that the WMV9 component of the AGP 6800's Purevideo unit is either non-functional or intentionally disabled. All other aspects of PureVideo (MPEG-2 decoding, deinterlacing, HQ-scaling) appear to function within specification, on all Geforce 6 products.
