RgTools 1.1

on GitHub

RgTools v1.1 (20210104)

• Source syntax for GCC
• CMake build environment, builds on Linux, at least on my (pinterf) Ubuntu 19.10 WSL
  (INTEL_INTRINSICS handling not implemented in the source, so it compiles on Intel at the moment)
• Fix: artifacts in RemoveGrain mode 19 for 10-16 bits

RgTools v1.0 (20200427)

• RemoveGrain mode 26-28, (C, up to SSE4.1)
  As said by the original author:
  Mode 26 SmartRGC: 26 = medianblur. Based off mode 17, but preserves corners, but not thin lines.
  Mode 27 SmartRGCL: 27 = medianblur. Same as mode 26 but preserves thin lines.
  Mode 28 SmartRGCL2

  pinterf: I swear that by seeing the code mode 28 is different from mode 27 but I cannot find a clip where 27 and 28 gave different results :)

• Repair mode 26-28 (25 is nonexisting, only exists in RemoveGrain)

• add "opt" debug parameter to Repair. 0:auto, 1:c 2:SSE2 3:SSE4.1 4:AVX2 (latter is not used here atm)

RgTools v0.99 (20200426)

• RemoveGrain mode 25 ("nondestructivesharpen") finally reverse engineered
  and ported from the original RemoveGrain package. (no-no, Repair has still 24 modes)
  Plus: 10-32 bits, Plus: sse4.1, avx2
• RemoveGrain: More correct 32 bit float in mode 6,7,8,9,15,16,23,24
  (proper clamping, chroma part specially treated)
• General: make C reference more similar to actual SIMD code
• fix: width<32 (or 16) with horizontal subsampling would use AVX2 (SSE2) on chroma
• (noticed: RemoveGrain: mode 11 and 12 SSE is simply avaraging
  instead of really do 1/4 1/2 1/4 kernel blur like C (todo).
  This is written in docs but even very old RemoveGrainSSE2 acts like this)
• Avisynth+ V8 header, frame property copy support
• opt debug parameter to RemoveGrain. 0:auto, 1:c 2:SSE2 3:SSE4.1 4:AVX2

RgTools v0.98 (20190814)

• Include "TemporalRepair" filter from old RemoveGrainT package (rewritten C and SIMD intrinsics from pure inline asm)
  Add Y8, YV16, YV24 besides YV12, drop YUY2 support.
  Add 10-32 bit support for Y, YUV and planar RGB formats
  Add int "opt" parameter (mainly for debug: 0=C 1=SSE2 2=SSE4.1) for testing specific code paths
• Codes for different processor targets (SSSE3 and SSE4.1) are now separated and are compiled using function attributes (clang, gcc).
• Other source changes for errorless gcc and clang build
• LLVM support, see howto in RgTools.txt
  Note: use at least LLVM 9.0 build 21 June 2019 due to a clang compiler bug (_mm_avg_epu8 related, fixed on April 14 2019) older versions are up-to 1/3 slower than the Microsoft build.
  See latest snapshot builds at https://llvm.org/builds/
• GCC 8.3 support, CMakeFiles.txt, see howto in RgTools.txt
• RemoveGrain/Repair different code paths for SSE2/SSE4.1/AVX2 instead of SSE2/SSE3/AVX2.
• Add documentation (from old docs, new part: gcc/clang howto)
• todo: Overview 32 bit float parts for some RemoveGrain modes (6, 7, 8, 9, 15, 16, 23, 24)
