amDCT "adaptive multifunction DCT", deblock, smooth, sharpen, range expansion filter.

It works! Thanks pinterf, greatly appreciated.
Edit: I have no found no other issues, I like what it does for the chroma as well.

Great! Will test ASAP.

Uploaded to Github as well. Code cleanup and further build enhancements: not now.

Would you please consider to switch/add Intel Compiler builds? The Community edition is completely free.

I find them faster, both on Intel and AMD.

Nth priority, but yes. I usually make abandoned sources to be compilable with gcc/clang/intel and support C-only non-Intel use cases.

Would be of much effort to expand to hbd and rgb?

I am testing it in 8 bits but it hasn't the precision I would like to.

I have a small issue:

SetMemoryMax()
SetCacheMode(0)
SetFilterMTMode("DEFAULT_MT_MODE", 2)
LoadPlugin("D:\Eseguibili\Media\DGDecNV\DGDecodeNV.dll")
DGSource("M:\In\Monster ~BDGE\1-1-01.dgi",ct=0,cb=0,cl=240,cr=240)
z_ConvertFormat(resample_filter="spline64", pixel_type="yuv420p16")
Resize8(720,540, kernel="z_Spline36Resize", noring=true, noring_c=true, fullc=true)
z_ConvertFormat(resample_filter="spline64",dither_type="error_diffusion",pixel_type="YUV420P16")
fmtc_bitdepth (bits=8,dmode=8)
amDCT(adapt=31,shift=5,quality=4,quant=9,matrix=8,expand=16,sharpWpos=6,sharpTpos=7,sharpWAmt=24,sharpTAmt=31,brightStart=205,brightAmt=30)
Prefetch(2,6)

Where I get:

amDCT: out of memory

As responded on your github issue: the "out of memory" was a false error. your clip must have mod8 dimensions: width and height must be multiple of 8.

On the other hand, doesn't amDCT have to be the first filter in the chain, to be able to catch the original 8x8 blocks before any resize and other operation? Or you are not using this feature of the plugins where this counts?

New release 1.4.2.
https://github.com/pinterf/amDCT/releases

This changeset was a hard and long process, mainly involving assembler rewrites and tests. And the many small items. It took about another 30-35 hours of work, so I'm just taking a rest now before the further cleanups.

## Changelog
- (20241210) v1.4.2
  - Rewrite all external assembly codes (fdct, idct, h263 and mpeg quant-dequants) to Intel intrinsics.
    It's now quicker - sometimes significantly - than the original.
  - Source: changed Windows specific threading code into C 17 version.
  - Source cleanup: removed lots of never used test codes from the source, rewrite some others. Move to cpp.
  - Add ability to pass Avisynth+ frame properties
  - Add support for any 8 bit planar YUV(A) or Y format (was: YV12 only)
  - Copy A alpha plane as well, if exists. (The filter works only on luma channel, other planes are simply copied)
  - Fix: add meaningful error message (Issue #2) for clips with non-mod8 width or height dimensions (was: out of memory)
  - Add Clang-cl LLVM build option, make source Clang friendly
  - Speedup examples:
  
| qtype | 32 bit clangcl | 32 bit msvc | 32 bit old 1.3 | 64 bit clangcl |
|-------|----------------|-------------|----------------|----------------|
| 1     | 6.12 fps       | 5.49 fps    | 5.40 fps       | 6.56 fps       |
| 2     | 6.67 fps       | 5.93 fps    | 5.28 fps       | 7.08 fps       |
| 3     | 4.09 fps       | 3.61 fps    | 3.22 fps       | 4.29 fps       |
| 4     | 6.66 fps       | 5.98 fps    | 5.29 fps       | 7.16 fps       |

Thank you Pinterf. I can't thank
you enough!

Vapoursynth support would be cool.
