Changes from 3.7.1 to 3.7.2

Additions, changes

  • Bump copyright year to 2022

  • Allow top_left (2) and bottom_left (4) chroma placements for 422 in colorspace conversions, they act as "left" (0, "mpeg2")

  • ShowRed/Green/Blue/Alpha/Y/U/V - support YUY2 input - support YV411 output - Copy alpha from source when target is alpha-capable - Fill alpha with maximum pixel value when target is alpha-capable but source ha no alpha component - Delete _Matrix and _ChromaLocation frame properties when needed. - More consistent behaviour for YUV and planar RGB sources, adaptive default pixel_type (YUV, planar or packed rgb)

  • Histogram "Luma": support 10-16 and 32 bits

  • Histogram: give parameter name "factor" and type 'float' for Histogram's unnamed optional parameter used in "Level" mode.

  • Histogram Levels: stop using shades of grey on top of bars.

  • Histogram Levels: use bar color 255 for RGB instead of Y's 235. (and scaled eqivivalents)

  • PropCopy: new string parameter "props": list of property names to copy (or ignore)

  • PropCopy: new bool parameter "exclude": whether property list is positive (copy) or negative (do not copy; blacklist)

  • PropDelete: accept an array string parameter as list of property names to remove

  • MergeRGB, MergeARGB - add MergeARGB parameter "pixel_type", similar to MergeRGB - accept pixel_type other than packed RGB formats, plus a special one is "rgb" - output format can be planar rgb(a) - Accept planar RGB clip in place of input clips and the appropriate color plane is copied from them - Fill alpha channel with zero when MergeRGB output pixel_type format is specified to have an alpha plane - frame property source is the R clip; _Matrix and _ChromaLocation are removed if R is not an RGB clip

  • "FadeX" filter family new parameters: int 'color_yuv' and array of float 'colors' similar to BlankClip

  • BlankClip: allow 'colors' with array size more than the number of actual planes.

  • BlankClip, AddBorders, LetterBox: no "alpha part must be zero" check for non-YUVA

  • Version (#261): New optional parameters int length, int width, int height, string pixel_type, clip c

  • Trim, AudioTrim: (#274) bool 'cache' (default true) parameter. Lower memory consumption but may be slower

Build environment, Interface

  • Fix (#276): C interface Win32 access: add V8 interface function names to avisynth.def to have undecorated function names

Bugfixes

  • Fix deadlock in GetFrame and Invoke (AvsPMod use case)

  • Fix Histogram AudioLevels half character upshift (regression since v3.6)

  • Fix (#255) Overlay "blend": using accurate formula with internal float calculation. (Issue #255)

  • Fix (#263). Escaping double-quotes in 'e' string results in error

  • Fix: Expr LUT operation Access Violation on x86 + AVX2 due to an unaligned internal buffer

  • Fix: Chroma full scale as ITU Rec H.273 (e.g +/-127.5 and not +/-127) in internal converters, ColorYUV and Histogram

  • Fix (#257): GreyScale to not convert to limited range when input is RGB. (regression in 3.7.1) GreyScale accepts only matrix names of limited range as it is put in the documentation.

  • Fix (#256): ColorYUV(analyse=true) to not set _ColorRange property to "full" if input has no such property and range cannot be 100% surely established.

  • Fix: Histogram "color" may crash on certain dimensions for subsampled formats. Regression since 20180301 r2632.

  • Fix: Histogram "color" and "color2" mode check and give error on Planar RGB

  • Fix: missing Histogram "color2" CCIR rectangle top and bottom line (black on black). Regression since 3.6.2-test1

  • Fix: Compare support 10-14 bits

  • Fix: Compare 'channels' parameter default to "Y" when input is greyscale;

  • Histogram "Audiolevels" and StereoOverlay to deny planar RGB

  • Fix: Histogram "Levels": prevent crash when factor=0.0

  • Fix: Histogram "Levels": fix regression incorrect "factor" applied for U/V part drawing when format was subsampled (non-444). Regression since 20160916 r2666

  • Expr: "scale_inputs" values to case insensitive and add "floatUV" to error message as an allowed value.

Optimizations

  • ConvertBits: no compulsory get frame #0 in constructor for frame properties if 'fulls' is directly specified
