I don't get the reason for that request either.

Supporting other GPU's which will be supporting Open CL.
So we all could enjoy the power of the GPU.

I assumed you wrote the code in CUDA, so I asked if there's a chance you'll port it into Open CL for a wider compatibility.

Nvidia wrote the code and provided an API for video decoding.

Unless and until the other guys (what's that acronym again, it starts with an A I think) provide an API for video decoding there's nothing I can do.

Thanks.

@neuron2:

ok, it's a newbie question, so don't be mad at me! But before changing graphic card and donate money I wanna be sure to have understood right.

DGAVCIndexNV is only a decoder, just to playback the video using the GPU, or it can be useful to recode the Blue-ray stream in some other format such as MKV or MP4. If the answer is yes, how can I do it with your sw?

I know that I'm looking for a sort of instant cookbook but there is any encoder out there that supports CUDA or my pre-order of GTX 285 is totally useless!? TIA !

Cheers you all

It's a decoder. But it is not intended for *playback* but just for delivering decoded frames via Avisynth.

It does not enable you to use CUDA for encoding. All it does is serve the decoded video via Avisynth. To go from there, you could use MEGUI and mkvmerge to make a re-encoded MKV.

The only encoder I know of that uses the GPU is Badaboom, which has mixed reviews.

While the author has agreed with your statement, IMO it's worth noting further that it's the only decoding solution that I've found that always decodes faultlessly!
So if it is important to you that your encodings always be perfect, you should factor this into your dec'n to get nvidia or not.

I used to have glitches here & there with my encodings, and I'm convinced on reflection that these were due to decoding problems, which have completely disappeared for me since getting my N9600GT OC and NV versions of neuron2's tools.

Hi neuron,

Would you mind if you have a look at this:

I had a look but I don't see a question there for me. Did I miss it?

Hi Neuron2, i've got a recording done on France DVB-T. (H264+AC3)

I tried to encode it via DGAVCDecNV and got artefacts. I cut out one of the damaged parts. This part is well played by VLC.
The file is well played also by the latest 1.0.9 DGAVCindex (non-NV).

Before that, i tried my old version of DGAVCIndex (1.0.0 beta 6) and this returns a:
Field pictures (PAFF) not currently supported.
I don't know if it's related.

So the stream is 1440x1080i with a resulting display size of 1920x1080i. I uploaded a sample with the artefact starting over frame 820.

I'm not seeing any artifacts. Can you please be more specific? Do you see them with DGAVCIndexNV or when serving with DGAVCDecodeNV? If the latter what is the script? Where are the artifacts? Do you see them in the script served to VirtualDub or only in your encode?

Try re-downloading 1.0.13. I've developed a bad habit of silently fixing bugs in the existing version online and not releasing a new version. Bad me. I'll try not to do it again.

I redownloaded 1.0.13, same issue. Here is the frame 824 as i see it

when serving with DGAVCDecodeNV using this simple script:

DGAVCDecodeNV_AVCSource("D:\VideoWork\Leon\cutout.dga")

I rebooted, still the same issue, thanks to kurtnoise to test it.
My card is a 8800 GTS 512Mo, on windows server 2008 x64.

I tried to read the same video with mplayerc-hc using internal dxva decoder and the video is full of artefacts.

Could it be possible that my card is damaged ?

Edit: I tried many other streams that works well with DXVA and DGAVCDecodeNV. So there's something wrong with this one.

I'm with 181.22, nvcuvid.dll is the one from DGAVCIndexNV package. Could you tell me what is your driver version ?
