Changes from 3.6 to 3.7 (20210111)

Additions

  • Resizers: throw error on too small dimensions vs. taps

  • Add ShowCRC32 debug filter. Parameters are the same as in ShowFrameNumber

  • Overlay: allow 4:1:1 input

  • RemoveAlphaPlane: do nothing on YUY2 instead of throwing an error message

  • AviSource: support non-printing characters in fourCC code: allow [number] style, e.g. G3[0][16]

  • AviSource: add Y410 (YUVA444P10) format support. Allow 'Y410' pixel_type hints.

  • AviSource: decode b64a, b48r, v210, P210, P010, P016, P216, v410, Y416, r210, R10k, v308, v408, Y410 fourCCs natively.

  • Add: AverageA

  • New: Average...: allow YUY2, RGB24/32/48/64 inputs

  • support for Win10 long file path option

  • internally refactored ConvertAudio

  • New: Histogram("color2") to support 10+ bits. Allow bits=x (x=8,9,10,11,12) parameter for this kind of histogram as well.

  • pass V3 (2.5) IScriptEnvironment for CPP plugins which directly load avisynth.dll and request CreateScriptEnvironment with version <= 3

  • Histogram("levels") to allow greyscale

Build environment, Interface, Source

  • Haiku support

  • PowerPC support

  • Support for building the core as a static library (mcmtroffaes)

  • Fixes for MinGW-w64 compilation

  • Shibatch, TimeStretch, and ImageSeq GCC build support

  • Shibatch, TimeStretch, and ImageSeq non-Windows support

  • project: Improve inclusion of the ghc filesystem helper library

  • project: Add a GitHub action workflow

  • Make frame property related constants to not collide with VapourSynth's definitions. (favour for multi-target plugins)

Bugfixes

  • Fix: AddBorders did not pass frame properties

  • Fix: propSet, propDelete and propClearAll not to ruin visibility of variables (property read functions are still kept being runtime only)

  • Fix: Average...: check for valid colorspace (e.g. no AverageB for a YUV clip)

  • Fix: Overlay: Actual frame of a mask clip would be freed up too early in MT environment

  • Fix: ConvertBits to ignore dither parameter instead of throwing error, in a 8 to 8 bit case

  • Fix: GeneralConvolution missing internal rounding on 8-16 bit formats

  • posix: fix crash when autoloading imports

  • ConvertBits(8): fix dither=1 (floyd) for RGB48/RGB64

  • Fix: Blur right side garbage: 16 bit+AVX2+non mod32 width

  • Fix: check fn signature with implicite "last" first (3.6 regression)

  • Fix: function parameters provided as arrays (e.g. GrunT callback of WriteFileIf)

  • Fix: ConvertBits (YUV): proper rounding when bit depth is reduced and origin is 10-16 bits (added rounder before bit-shift)

  • Fix: proper handling of autoload directories precedence

  • Fix: ScriptClip + Runtime function object (which are new in 3.6) under heavy multithreading

  • fix: GeneralConvolution: incorrect parse of negative integer coefficient (+1) regression since r2772

  • fix: GeneralConvolution: possible crash when chroma=true for 420 and 422 formats

  • Fix 3.6 regressions - when explicit "return last" was needed when followed by legacy function definition. - Windows XP is supported again (thread local storage workaround) - Stabilize CPP 2.5 plugins - allow forced named arrays usage again from plugins (MP_PipeLine)

Optimizations

  • Overlay: may work quicker, most input/overlay/mask/output clip format conversions moved to filter constructor
