I get that problem, too.
Indexed the sample using 1.0.5, started the server and opened the dga file with DGAVCDecodeNV_AVCSource("sample.dga"). Viewing in VirtualDubMod.

It doesn't happen for me. Does it show wrong in DGAVCIndexNV?

Does it show wrong using 1.0.4 (non server version)?

Please post the log from a preview.

[Guest]

Whoops, I'm duplicating it with the uploaded binaries. Stand by...

[Guest]

Redownload 1.0.5. I forgot that DGAVCDecodeNV.dll was updated also.

[Zwitterion]

Works now.

[Guest]

Thanks guys, what would I do without you?

EDIT: I just updated the sample CUVID Client application as well.

I wake up and my problems are gone !! Thank you.

Sorry, if this is a bit offtopic, but which method of deinterlacing is used by the PureVideo deinterlacer?
How does it compare to Yadif or even Mcbob in terms of Quality?
I understand there is no way of choosing a particular method in the nvidia control panel. Is there a difference in terms of method/quality between the XP and Vista drivers?

I guess my basic question is: If I have an interlaced source and want to archive good quality, should I use Yadif or PureVideo?

[Guest]

If you look through the 16 pages of the thread, somewhere you will find some screenshots. In my opinion, PureVideo is better and faster than the available Avisynth filters.. It does only single rate for now (no bobbing).

I don't think there's any difference between XP and Vista, as it is a hardware function.

Indeed, I did a mini comparison of TempGaussMC (using naive defaults) vs the built in VP deinterlacing and nvidia's implementation came out on top. IMO, for the naive user who just wants it to work right, the deinterlacing interface provided by DGAVCDecNV is very handy, or well anyone who wants good deinterlacing


If I find more interlaced H.264 sources I'll post the results too.

Edit: Here are the results

Strange error using with x264 on Vista 64.


avis [error]: unsupported input format (DIB )
x264 [error]: could not open input file 'd:\test.avs'

I've used the same workflow I have always used on winxp.

The avs file loads fine in virtualdub and mpc.
And as far as I can tell it is yv12.

edit: and it works with the same x264.exe in megui but not the cli.

@Neuron2 :
1 - I use TSMuxer, eac3to and DGAVCindexNV to extract audio from a m2ts file. The 3 resulting ac3 are exactly the same (great !!) but the one extracted from DGAVCindexNV is marked with a delay of -265 ms. And when remuxed with this delay, the file is not in sync. I tried two others files muxed with TSMuxer and the -265 ms is present every time.
Do you have any clue on that ?
2 - What is the roadmap of DGAVCindexNV : VC1/MPEG2 support ?

Thanks for all, my first encode with the CUVidServer is grrrrreeeeaaaattt.

Provide:

1. The version of DGAVCDecNV you are using.
2. The x264 CLI command that fails, and the version of the x264.exe you used.
3. Your exact script.
4. A piece of the unprocessed source stream that will allow me to duplicate your issue.

But if the exact same thing doesn't fail on XP, you're on your own because I don't use Vista 64.

[Audionut]

1. latest.
2.

--crf 18.0 --level 4.1 --keyint 24 --min-keyint 2 --ref 3 --mixed-refs --bframes 3 --b-adapt 2 --weightb --direct auto --subme 7 --trellis 1 --partitions p8x8,b8x8,i4x4,i8x8 --8x8dct

--no-ssim --output "output" "input"

3.

loadplugin("d:\dgavcdecodenv.dll")
avcsource("d:\test.dga")
spline36resize(1280,544)
removegrain()

4.Give me a minute.

The error occured with a basic loadplugin, avcsource script aswell.

If you give me an unprocessed source stream that includes the beginning of the stream and has an AV sync event like a door slam or someone talking, then I can investigate.

2 - What is the roadmap of DGAVCindexNV : VC1/MPEG2 support ?

Things I'd like to do:

PureVideo bobbing
VC-1
MPEG1/2

But not on vanilla 32-bit XP?

And what happens if you just load the script into VirtualDub?

Where did you put nvcuvid.dll? You should not use nvcuvid64.dll. You should put nvcuvid.dll in your sys32wow directory. That may not be the exact name but it is something like that.

Also, check the Nvida driver version. It must support CUDA.

[Audionut]

1. no

2. works fine. Also works fine with the same x264.exe in megui.

3. Didn't put anywhere, but tried system32 and syswow64, didn't make any difference. Works in megui without me putting it anywhere.

4. latest driver 180.43 iirc.


See pm for sample.

Edit. It seems awfully strange that it doesn't work in cli but does in megui.

[Guest]

Your answer to 1 is ambiguous. Does it or does it not work fine on 32-bit XP?

You have to put the correct DLL in the correct place! Get rid of all the existing nvcuvid.dll and nvcuvid64.dll and put the nvcuvid.dll from the zip file into the correct directory for Vista 64 32-bit DLLs. I don't lknow what that is as I don't use Vista 64.

[Audionut]

Worked fine on 32-bit xp.

There are no nvcuvid or nvcuvid64.dll's on my system. I tried putting nvcuvid.dll in the correct directory. It didn't make a difference.

[Guest]

I can't help you with Vista 64. Sorry. When you figure it out, please let us know.
