Please write a full sentence so that I may have at least a chance of understanding your point.

@xopowo

Have you tried installing the latest version of the Nvidia drivers: 178.13? Also, please ensure that you have only one instance of nvcuvid.dll present and that it is the one shipped with the version of DGAVCDecNV that you are using (which should be 1.0.1 or 1.0.2). Make sure you have one version of the DLL in your system32 directory and no others anywhere else (including your Avisynth plugins directory and the directory that DGAVCDec is installed and its subdirectories).

What video card do you have? How much memory does it have?

I always encoded BD AVC to x264 by megui, Could you tell me how to use DGAVCDecNV in megui.

I can't find in mannual

Guest · 30th September 2008, 15:08

Try asking the MEGUI authors.

Is the dga created with DGAVCindexNV and DGAVCindex are compatible ? I'm asking this as I would use DGAVCindex to set up staxrip or megui and just change to DGAVCIndexNV in avs script before launching the job.

They are not compatible.

Sorry, I had not much time this morning.

I'm referring to this pic here:
http://forum.doom9.org/showpost.php?...&postcount=380
The sample is still here (It's frame 92):
http://forum.doom9.org/showpost.php?...&postcount=298

dgavcdecnv102 gives the following result:

command line:

Code:

DGAVCDecodeNV_AVCSource("00014.dga", deinterlace=true)

It seems to interpolate the top field and keep the bottom field, even though use_top_field=true is used by default.

NVIDIADisplayWin2K(177_84)Int.exe ** that is the name of the driver I'm using. I went to the nVidia site again and this is the only one that it lets me download?

nvcuvid.dll - I have one on the box and it is in the \system32 folder.

VIDEO CARD -
GPU Type : GeForce 8600 GTS
GPU Clocks : Core 675 MHz / RAM 1008 MHz
GPU Memory : DDR3 256MB

It's quite possible that you don't have enough memory on your GPU card.

Have you tried what neuron2 suggested in the first post?

2. If that does not work, please move the nvapi.dll and nvcuda.dll to the Windows System32 directory (don't move nvcuvid.dll).

Audionut · 1st October 2008, 15:13

Well the manual actually states.

Quote:

You also need to copy the nvcuvid.dll DLL that ships with DGAVCDecNV into your Windows System32 directory.

BTW, I got it working.

What video card is recommended? I currently have a GeForce 8500 GT w/ 256MB 128-bit GDDR2 in one computer and a Quadro FX 570 w/ 256MB in another. The NVidia website reports that the FX 570 has "PureVideo HD Technology" and CUDA although I can't find specific reference to VP2.

I'm giving it a try on the 8500 tonight and I'll report back.

Guest · 1st October 2008, 20:11

For multi-instance, you're going to need a lot of memory. My 8500GT card has 1024MB.

BTW, regarding problems in MEGUI, etc., I am working on a solution such that all instances use a single instance of D3D and float the CUDA contexts. If this succeeds it will have the useful consequence of dramatically reducing memory needs for multi-instance.

I'm not concerned about the overhead of floating contexts because in practice the usage is serialized.

hajj_3 · 1st October 2008, 20:45

neuron, have you done tests to see what speed difference different cards make, is the ram alot more important than the clock speeds or the memory speeds? Would help quite alot of people.

I know this is off topic but does the amount of ram make a massive difference for DXVA-HD-Balanced x264 profile in megui? As i use the following tools to create my 720p bluray encodes and not dgavc:

GraphStudio, Eac3to, x264, AVSP, AviSynth, FFmpeg source, MeGUI, Haali, ffdshow, SurCode DTS, Arcsoft DTS DLLs, Arcsoft Total media.

Guest · 1st October 2008, 21:42

I've not run any tests as I have only one card.

I won't answer OT questions here and no-one else should either.

Sagekilla · 1st October 2008, 23:14

Would it theoretically be possible to utilize two cards to help with multi instance decoding? I could imagine the instances would be split between the two.

Guest · 1st October 2008, 23:20

Let's get the basic operation working and stable before looking for exotic scenarios.

To neuron2:

Well, may be little offtopic, but I am confused. I would like to pay for your product, but have no PayPal account and would like to avoid creating the one. On your WEB page you were stating: "Note that you do not need to have a PayPal account; you can pay with a credit card account also.", but when I do go to "Donate" page, the only option is to create the PayPal account... Is there the way to pay by Credit card WITHOUT creating this account?
