Changes from to 3.4 to 3.5 (20200302)

Additions

  • Layer: support RGB24 and RGB48 (internally processed as Planar RGB - lossless pre and post conversion)

  • New bool IsVersionOrGreater(int majorVersion, int minorVersion [,int bugfixVersion]) function

  • Overlay: show error when Overlay is fed with clips with different bit depths

  • New: AddBorders, LetterBox: new color_yuv parameter like in BlankClip

  • WavSource: really use "utf8" parameter, fix some debug asserts

  • TimeStrech: pass internal errors as Avisynth exception text (e.g. proper "Excessive sample rate!" instead of "unhandled C++ error")

  • "Expr" helper constants "yrange_min", "yrange_half", "yrange_max"

  • "Expr" new parameter: bool clamp_float_UV

  • "Expr" "clamp_float" is not ignored (and set to true) when parameter "scale_inputs" auto-scales 32 bit float type pixels

  • "Expr" "yscalef" and "yscaleb" keywords similar to "scalef" and "scaleb" but scaling is forced to use rules for Y (non-UV) planes

  • "Expr" new allowed value "floatUV" for scale_inputs supporting special 32 bit chroma case

Build environment, Interface

  • Native Linux, macOS, and BSD support.

  • Build system: Cmake: use platform toolset "ClangCL" for using built-in Clang support of Visual Studio (Since VS2019 v16.4 there is LLVM 9.0 support)

Bugfixes

  • Fix: ConvertBits 32->8 for extremely out of range float pixel values. When pixel value in a 32 bit float format video was way out of range and greater than 128 (e.g. instead of 0 to 1.0 for Y plane) then the ConvertBits(8) had artifacts.

  • Fix potential crash on exit or cache shrink (linux/gcc only?)

  • Fix: RGBP to 444 8-14bit right side artifacts at specific widths

  • Fix: "scalef" and "scaleb" for 32 bit input, when scale_inputs="floatf" produced wrong result

  • Fix: missing rounder in V channel calculation of PlanarRGB->YUV 8-14bits SSE2 code

  • Fix: TemporalSoften possible access violation after SeparateFields (in general: after filters that only change frame pitch)

  • Fix: Shibatch.DLL Access Violation crash when exit when target rate is the same as vi.audio_samples_per_second or audio_samples_per_second is 0

  • Fix: Resizers to really resize alpha channel (YUVA, RGBPA)

  • Fix: crash when outputting VfW (e.g. VirtualDub) for YUV444P16, other fixes for r210 and R10k formats
