NVIDIA Decoder

[observer_11]

I have a couple different Nvidia cards and I believe the Nvidia decoder hardware acceleration used to be available only thru the pure video decoder but now I heard that is no longer true and the latest greatest decoder is integrated within the more recent driver bundles? :confused:

Can anyone confirm if this is true? Is this how ATI users obtain their video decoder?

ATI uses AVIVO, similar I guess to Nvidia. I'm about to switch from an HD 3870 to a 9600GT sadly, I really like the ATI card but it seems to be unstable with h.264 HDTV.

Have you tried the media player classic home cinema decoder, it supports h.264 dxva decoding on ati cards and hopefully in the near future they will fix the nvidia implementation.
here is a link http://tibrium.neuf.fr/index.html
you can download the standalone media player classic or the individual direct show filters (.ax files), you will have to register the .ax files with regsvr32 from the command line. I have the registry entries that you can add to make it so you can right click on .ax file and register it that way too if your interested.

This is what I have heard as well but I havent seen this, I had to get the older nvidia purevideo decoder a while back because it was the only thing that would give me decent play back of hd video. At the time it seemed like the decoder was included and it wasn't.

It appears that after some reading the "pure video hd decoder" really isnt a decoder. The driver release notes indicate that it is more of a driver thing and frame work thing that enables more features to off load more of the work to the video card though dxva and other special pathways for h264.

If I am wrong please correct me.

Actually, I think it's just that their drivers for the new cards allow other decoders to support improved levels of hardware acceleration. Like their new PureVideo HD is just a technology that other decoders can use, but it's not it's own decoder like the PureVideo decoder was/is. What dumb and confusing marketing, huh?

ATI cards usually include a decoder, but not always. Back in the day, the ATI-specific version of the Cyberlink decoder that came with my 9200 was excellent, offering better playback performance than any others I tried. The decoder that came with my x1600 was disappointing despite the AVIVO hype, and I found I got much better performance with the NVidia PureVideo decoder.
