Also, just open the script in VirtualDub2 to eliminate the encode. I've tested various PQ streams with a cube like yours and everything is fine.

What nvidia driver are you using?

That stuff is present in the source file

That is the encoded one.

It must be your encode because it is resized.

I resized to make it faster.

Please provide the corresponding source stream. Thank you.

Try without the prefetch.

No difference at all.

If DGCube receives YUV420P16 then it outputs YUV420P16.

Ok, now I understand. We just need the support for limited range cubes from Warner too.

Ah, I forgot that my YUV <-> RGB conversions

And what about my error? Any idea?

Rocky wrote: ↑

fullrange is inapplicable for YUV420P16 input

What would happen if DGDecodeNV outputs a 444 stream?

Rocky wrote: ↑

Thu Aug 18, 2022 8:18 am

when false we specify that the input is limited and the output should be limited

I don't know if possible but if the LUT produces limited from full or full from limited? Perhaps it should be better to specify what we are giving as input and what we want as output?

Good move. PQ sucks rocks.

Indeed.

Depends on at least three things. Is the LUT made for limited or full-range input/output? Is the source limited or full range? Should the output be limited or full range? 1) Input, in my case, is PQ video from UHD, so we can assume it's limited range. 2) My LUT wants full range. 3) The output shoul...

Let's test what we have and I'll look into the range stuff in parallel. In the examples you write: loadplugin("...\dgdecodenv.dll") loadplugin("...\dgcube.dll") dgsource("THE GREAT WALL.dgi") DGCube("PQ_to_BT709_slope.cube", fullrange=false, interp="tetrahedral") What is the output format and range...

Perhaps you already know but LUT cubes can work in RGB or Studio RGB, i.e. full TV range or limited TV range. On PQ to HLG, for full TV range, such as BBC ones, you would need: #From 4:2:0 16bit planar Narrow Range to RGB Planar 16bit Full Range z_ConvertFormat(pixel_type="RGBP16", colorspace_op="20...

That was all done in C code. Now I'll port it to the CUDA kernel. That should be plain sailing.

Eager to test it.

And it gives a raison d'etre for DGCube.

Do you think it's possible to have the necessary color space conversion ported to CUDA, to offload the cpu as much as possible?

OpenCV supports it easily and, if I am not wrong, it's written in CUDA... so...

Please let the Doom9 guys know about this.

Your wish is my command.

P.S: Will you add tetrahedral to AVSCube too?

I compared scripts with BlankClip() source and no conversions and things are as expected.

Please, post your script.

Re-download DGCube to get the fix, i.e., ability to open any size cube file.

Rapidly tested and it seems to be working.

I will bench and post results.

Your cube is size 33.

Is the 65 size related to CUDA only? AVSCube works ok.

1. Where are you loading avsresize.dll? No need as it's in AVS+ default folders. 2. Can you give me the cube file? I can give you a identity one, that crashes too: IDENTITY.7z which must be size 65 Are you meaning kB or what? Both BBC and Warner Bros licensed cube files are around 1 MB. I asked a f...
