AviSynth+ thread Vol.2

[wonkey_monkey]

Is there any documentation/example for passing functions as parameters to plugins ('n' in AddFunction parameter string)?

New build.
Avisynth r4504
https://github.com/pinterf/AviSynthP...3.7.6pre-r4504

Full change log:
https://avisynthplus.readthedocs.io/...gelist376.html

20260212 3.7.5.r4504 (pre 3.7.6)
--------------------------------
* Fix: inaccurate ColorBarsHD 10+ bit values. Now they are derived from the 32-bit float 
  RGB definitions instead of upscaling a 8 bit precalculated YUV value.
  Add Ramp section the lead-in-lead-out.
* Fix: GreyScale + SSE2 + RGB32 + matrix="RGB" overflow. 
  Rare usage; "RGB" matrix (Identity) uses a 1.0 coefficient which exceeds the signed 16-bit 
  SIMD limit of 32767 at 15-bit precision. Added bounds checking to fallback to C-code for any 
  coefficients >= 1.0 or < −1.0.
* Fix: YUV->RGB limited range matrix accuracy for 10-16 bits.
* Use a different rounding in matrix coefficient's integer approximation.
* "ConvertToPlanarRGB": ``bits`` parameter: on-the-fly bit-depth conversions to YUV->RGB conversion. 
  - Full range target: 8-16 bits internal calculation is in 32-bit float.
  - Limited range target: a quicker, bit accuracy optimized integer calculation path.
* Not Fixed: Speed degradation when in-constructor GetFrame(0) (e.g. frame-property getter) 
  is used. Disable internal Cache object creation. Does not work in complex scripts, preparation 
  is 5-10 min instead of <1 sec. Investigation continues (Issue #476: https://github.com/AviSynth/AviSynthPlus/issues/476)
* Avoid MTGuard and CacheGuard creation if filter returns one of its clip parameter unaltered.
* Add some avx2 stuff to Layer and Invert
* Optimization: Overlay "Blend": aarch64 NEON optimization

20260203 3.7.5.r4483 (pre 3.7.6)
--------------------------------
* rst documentation update: RGBAdjust https://avisynthplus.readthedocs.io/en/latest/avisynthdoc/corefilters/adjust.html
* rst documentation update: ColorYUV https://avisynthplus.readthedocs.io/en/latest/avisynthdoc/corefilters/coloryuv.html
* optimization: add AVX2 TurnLeft/TurnRight/Turn180 (R/L: 1,5-3x speed).
* optimization: ConvertBits AVX2 integer->float
* optimization: ConvertToPlanarRGB(A): YUV->RGB add AVX2 (2-3x speed)
* optimization: ConvertToPlanarRGB(A): YUV->RGB 16 bit: a quicker way (1,5x)
* Fix: C version of 32-bit ConvertToPlanarRGB YUV->RGB to not clamp output RGB values.
* ConvertToPlanarRGB(A): add bits parameter to alter target bit-depth.
* ConvertToPlanarRGB(A): from YUV->RGB full range output: optimized in-process when bits=32, other cases call ConvertBits internally.
* Fix: Packed RGB conversions altering the bit-depth (e.g. rgb32->ConvertToRGB64() worked always in full range.
* Add more AVX512 resampler code. (WIP)
* Add more AVX512_BASE code paths (Resamplers)
* Build: add _avx512b.cpp/hpp pattern in CMake to detect source to compile with base (F,CD,BW,DQ,VL) flags.
  However AVX512_BASE itself is set only when AVX512_FAST found.
  For pre-Ice Lake (older AVX512) systems you can enable it with SetMaxCPU("avx512base+") and get the optimized AVX512_BASE functions.
* Build: add new architecture z/Architecture

Perhaps this one:
https://avisynthplus.readthedocs.io/...n_objects.html

EDIT:
or in function parameter
https://avisynthplus.readthedocs.io/...nalfilter.html

and in Avisynth source (runtime functions accept function objects)

I don't know why are minor DEBUG fixes added?

It's a single code base. pinterf and others may want to build with _DEBUG when troubleshooting. Did I miss your point?

[pinterf]

Yes, minor, since compared to last week's ~40 hrs work on the project it was just a quick moment to copy-paste _RPT3 and not modifying the _RPT3 to _RPT4. Sorry for the inconvenience.

[pinterf]

(I don't know what private compiler settings are you using again, for me it said '0 warning(s)', vs. your environment which drives it to an error. Anyway, thanks for the report. Fixed.)
