ImageSourceNV plugin

[Argaricolm]

I'v made a plugin that uses nvjpeg api to decode jpeg source files and convert their color space to YUV444. That is CUDA accelerated.
You will need CUDA toolkit 12 (or 11.8) installed and MS C++ redistributables.

Usage:
ImageSourceNV("C:\Folder1\Folder2","jpg",1,34609,24000,1001)

1: Folder path without ending slash.
2: Files extension.
3: First frame.
4: Last frame (included).
5: FPS numerator.
6: FPS denumerator.

File names should be 6 numbers with leading zeroes (%06d).

Source included.

your plugin for x86 or x64??

[Reel.Deel]

It's x64.

@Argaricolm

Thank you for the plugin. Any chance of a CUDA 11.8 compile for us Windows 7 users?

[Selur]

A VapourSynth version would be nice.

If you're reluctant to install the 3GB CUDA toolkit, you can the individual files also. According to DependencyWalker it only needs these two files:

• cudart64_12.dll: https://developer.download.nvidia.co...indows-x86_64/
• nvjpeg64_12.dll: https://developer.download.nvidia.co...indows-x86_64/

But these 2 dlls are surely have other dependencies...
Added CUDA 11.8 version. Redownload archive.

Tried out the 11.8 version but it seems that it requires nvjpeg from Cuda 12?



If not too much trouble, maybe a static build would be better.

Fixed. Redownload.
Made static linking. But it links only C++ library functions. Cuda is still needed.

Thanks for the update. I got it to run but the output is only a green image:

ImageSourceNV("E:\Images", "jpg", 1, 6, 24000, 1001)

Dimensions, frame count and frame rate are correct, though.

I did have to fetch two additional dependencies for cudart64_110.dll (api-ms-win-core-libraryloader-l1-2-0.dll and api-ms-win-security-systemfunctions-l1-1-0.dll). I'm not sure why they're missing or if they are meant for Win10.

Image width & height are got using nvjpeg. So - it is working.
I'v tested it with 1048 height and working here.
What software are you using to open avs? And which version of avisynth?

[Emulgator]

My main system is down so I can only remote guess from a replacement system below the specified abilities:
The given commandline does not specify spaces and wants to see 000000.jpg, 000001.jpg ?
And any green frame would usually be YUV samples decoded as 0,0,0 (invalid, btw.)

[Argaricolm]

Yes, it needs file names: 000001.jpg
6 numbers. Same as in input parameters.
It gets frame settings from first jpeg.

I'm using AviSynth 3.7.3 test 9 and tested with VDub2 and AvsPmod and both show the same result. Image is 4:2:0.

I also noticed that ImageSourceNV("E:\Images", "jpg") results in "ZeroDivisionError: float division by zero".

System up again, success.
Threw the cuda 11.8 .dlls into system32, used the 11.8 plugin version.

From non-subsampled .jpg source filter returns frames decoded to YV24, 23.976fps
Tested folder with 5 frames starting 000001.jpg...000005.jpg
returns the 1st frame 000001, then repeats the same frame until framecount.

Tested folder with 5 frames starting 000000.jpg...000004.jpg
returns frame 000000, then 000001, then 000002, then repeats 000002, then 000000.
(My bad: I had given some pictures with differing width/height, first 3 were portrait, then 000003 was landscape X-}
00000.jpg: No video

Now a folder renamed to 000000.jpg to 000200.jpg, all same dimensions 4608x3456, orientation landscape.
These 4:2:2-subsampled .jpgs result in chroma planes with half width,
so resizing would be necessary afterwards, or better: chromaspace signalling should match.

ImageSourceNV() returns all frames decoded with unresized chroma planes to YV24, 23.976fps.

With prefetch(16,200) 4k frames can be decoded almost in film speed (RTX3080 @ 15..30%).
Not bad for flipping through albums.

I used the oldest versions available (cudart 11.4.108 / nvjpeg 11.5.2.120) and now it works for me. I will go back and see what is the latest version that works for me since I'm on Windows 7. I think the problem may be that the newest 11.8 cudart requires api-ms-win-core-libraryloader-l1-2-0.dll and api-ms-win-security-systemfunctions-l1-1-0.dll while the oldest one does not.

Edit: the latest cudart that does not require those additional dependencies is 11.6.55.

Thank you, good to know.
