Avisynth+ r2772 (20181220)

https://forum.doom9.org/showthread.php?t=168856

  • Fix: Expr: possible Expr x64 crash under specific memory circumstances (AVX2 only)
  • Fix: Expr: safer code for internal variables "Store and pop from stack" (see: Internal variables at http://avisynth.nl/index.php/Expr)

Avisynth+ r2768 (20181218)

  • New: Expr: allow input clips to have more planes than an implicitely specified output format
    Expr(aYV12Clip, "x 255.0 /", format="Y32") # target is Y only which needs only Y plane from YV12 -> no error
  • New: Expr: Y-plane-only clip(s) can be used as source planes when a non-subsampled (rgb or 444) output format implicitely specified
    Expr(Y, "x", "x 2.0 /", "x 3.0 /", format="RGBPS") # r, g and b expression uses Y plane
    Expr(Grey_r, Grey_g, Grey_b, "x", "y 2.0 /", "z 3.0 /", format="RGBPS") # r, g and b expression uses Y plane
  • Fix: ConvertToYUY2() error message for non-8 bit sources.
  • Fix: Y32 source to 32 bit 420,422,444 (introduced in big the zero-chroma-center transition)
  • Fix: ShowY, ShowU, ShowV crash for YUV (non-YUVA) sources
  • Speedup: ConvertToY12/16... for RGB or YUY2 sources where 4:4:4 or YV16 intermediate clip was used internally
    (~1.5-2x speed, was a regression in Avs+, use intermediate cache again)
  • Fix: Allow ExtractY on greyscale clips
  • ImageReader/ImageSource: use cache before FreezeFrame when result is a multiframe clip (fast again, regression since an early AVS+ version)
  • Resizers: don't use crop at special edge cases to avoid inconsistent results across different parameters/color spaces
  • Fix: Histogram 'classic': rare incomplete histogram shown in multithreading environment
  • Fix: ImageReader and ImageWriter: if path is "" then it works from/to the current directory.
  • GeneralConvolution: Allow 7x7 and 9x9 matrices (was: 3x3 and 5x5)
  • GeneralConvolution: All 8-32 bit formats (was: RGB32 only): YUY2 is converted to/from YV16, RGB24/32/48/64 are treated as planar RGB internally
    Since 32 bit float input is now possible, matrix elements and bias parameter now is of float type.
    For 8-16 bit clips the matrix is converted to integer before use.
  • GeneralConvolution: Allow chroma subsampled formats to have their luma or chroma processed. E.g. set chroma=false for a YV12 input.
  • GeneralConvolution: new parameters: boolean luma (true), boolean chroma(true), boolean alpha(true)
    Default: process all planes. For RGB: luma and chroma parameters are ignored.
    Unprocessed planes are copied. Using alpha=false makes RGB32 processing faster, usually A channel is not needed.
  • GeneralConvolution: MT friendly parameter parsing
  • New: UTF8 filename support in AviSource, AVIFileSource, WAVSource, OpenDMLSource and SegmentedAVISource
    All functions above have a new bool utf8 parameter. Default value is false.
  • Experimental: new syntax element (by addewyd): assignment operator ":=" which returns the assigned value itself.
