Avisynth Plus change log ------------------------ Source: https://github.com/AviSynth/AviSynthPlus For a more logical (non-historical) arrangement of changes see readme.txt 20200302 3.5.0 -------------- - New: Native Linux, macOS, and BSD support. - 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?) - Layer: support RGB24 and RGB48 (internally processed as Planar RGB - lossless pre and post conversion) - 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 - Overlay: show error when Overlay is fed with clips with different bit depths - New function: bool IsVersionOrGreater(int majorVersion, int minorVersion [,int bugfixVersion]) function Returns true if the current version is equal or greater than the required one in the parameters. The function is checking the current version against the given parameters (similar to a Windows API function) e.g. IsVersionOrGreater(3, 4) or IsVersionOrGreater(3, 5, 8) - New: "Expr" helpers: - Constants "yrange_min", "yrange_half", "yrange_max" Unlike the luma/chroma plane adaptive "range_min", "range_half", "range_max" these constants always report the luma (Y) values - new parameter: bool clamp_float_UV (default false) this parameter affects clamping of chroma planes: chroma is clamped between 0..1.0 instead of -0.5..0.5s - "clamp_float" is not ignored (and set to true) when parameter "scale_inputs" auto-scales 32 bit float type pixels - New "yscalef" and "yscaleb" keywords similar to "scalef" and "scaleb" but scaling is forced to use rules for Y (non-UV) planes - new allowed value "floatUV" for scale_inputs. In short: chroma pre-shift by 0.5 for 32 bit float pixels Affects the chroma plane expressions of 32 bit float formats. Shifts the input up by 0.5 before processing it in the expression, thus values from -0.5..0.5 (zero centered) range are converted to the 0..1 (0.5 centered) one. Since the expression result internally has 0..1.0 range, this then is shifted back to the original -0.5..0.5 range. (since 2.2.20) Note: predefined constants such as cmin, cmax, range_min, range_max and range_half will be shifted as well, e.g. the expression will see range_half = 0.5 - These modifications are similar to Masktools2 2.2.20+ - 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 - 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. Use: Tools|Get Tools and Features|Add Individual Components|Compilers, build tools, and runtimes [X] C++ Clang compiler for Windows [X] C++ Clang-cl for v142 build tools (x64/x86) (for LLVM Clang installed separately, please use llvm or LLVM - no change in its usage) - New: AddBorders, LetterBox: new color_yuv parameter like in BlankClip - 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 - 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") 20191021 3.4.0 -------------- - Merges in the MT branch, the current state of pinterf/MT, and packaging fixes - Development HEAD is the master repo again in https://github.com/AviSynth/AviSynthPlus - Bumps version to 3.4 20190829 r2915 -------------- - Changed: Trim, FreezeFrame, DeleteFrame, DuplicateFrame, Reverse and Loop are using frame cache again (similar to classic Avs 2.6) - Enhanced: Expr: faster exp, log, pow for AVX2 (sekrit-twc) - ConditionalReader: allow empty value in text file when TYPE string - Fix: Expr: fix non-mod-8 issues for forced RGB output and YUV inputs - New: AviSource support v308 and v408 format (packed 8 bit 444 and 4444) - Fix: AviSource v410 source garbage (YUV444P10) - Fix: Expr: when using parameter "scale_inputs" and the source bit depth conversion occured, predefined constants (ymin/max, cmin/max, range_min/max/half) would not follow the new bit depth - Fix: ConvertToRGB from 32bit float YUV w/ full scale matrixes (pc.601, pc.709, average) - Fix: FlipHorizontal RGB48/64 artifacts - Enhanced: a bit quicker FlipHorizontal - Fix: RGB64 Blur leftmost column artifact - Enhanced: quicker RGB24/48 to Planar RGB for AVX2 capable processors - Fix: Strip alpha channel when origin is YUVA and using ConvertToYV12/ConvertToYV16/ConvertToYV24 funtions - Fix: garbage with ConvertToYUY2 from 8 bit YUVA colorspaces - Enhanced: Colorbars to accept RGB24, RGB48, YV411 and 4:2:2 formats for pixel_type (now all colorspaces are supported) - Fix: shifted chroma in ColorBars and ColorBarsHD for YUV444PS - Fix: ConvertToY8, ConvertToYV12, ConvertToYV16, ConvertToYV24 are now allowed only for 8 bit inputs. Formerly these functions were allowed for 10+ bit colorspaces but were not converted to real 8 bit Y8/YV12/16/24. Use ConvertToY, ConvertToYUV420, ConvertToYUV422, ConvertToYUV444 instead which are bit depth independent - New parameter in ColorYUV, RGBAdjust, Overlay, ConditionalReader. string "condvarsuffix" Allows multiple filter instances to use differently named conditional parameters. Prevents collision and overwrite of variables which are used by different ConditionalReader instances. See Conditional Variables section of http://avisynth.nl/index.php/ColorYUV. How does it work: when reading the global variables, the "condvarsuffix" parameter is appended to the variable name. E.g. ColorYUV will read "coloryuv_gain_y_a" instead of "coloryuv_gain_y" when condvarsuffix = "_a" is provided for ColorYUV. In the matching ConditionalReader one have to use the modified name as well: ConditionalReader("coloryuvoffset.txt", "coloryuv_gain_y", false, CondVarSuffix = "_a") # "_a" is added here by parameter or specify the suffixed name directly: ConditionalReader("coloryuvoffset.txt", "coloryuv_gain_y_a", false) # "_a" is added here manually Example: Colorbars(512,256).ConvertToYV12.Trim(0,299) ConditionalReader("coloryuvoffset.txt", "coloryuv_gain_y", false) a=ColorYUV(cont_y=10, conditional=true) Colorbars(512,256).ConvertToYV12.Trim(0,299) ConditionalReader("coloryuvoffset2.txt", "coloryuv_gamma_y", false, condvarsuffix="_a") b=ColorYUV(cont_y=10, conditional=true, condvarsuffix="_a") # will read coloryuv_gain_y_a, coloryuv_gamma_y_a, etc. Stackvertical(a,b) - Fix: ColorBars: pixel_type planar RGB will set alpha to 0 instead of 255, consistent with RGB32 Alpha channel - Fix: text colors for YUV422PS - regression since r2728 (zero-centered chroma) - New: VirtualDub2 to display 8 bit planar RGB (needs up-to-date VirtualDub2 as well) VfW interface to negotiate 8 bit Planar RGB(A) with FourCCs: G3[0][8] and G4[0][8], similar to the 10-16 bit logic (When you would still stick with RGB24/RGB32/RGB64 export, use OPT_Enable_PlanarToPackedRGB = true) - Fix: planar RGBA Alpha on VfW was uninitialized because it wasn't filled. - Layer: big update Previously Layer was working only for RGB32 and YUY2. Overlay was used primarily for YUV. Now Layer accepts practically all formats (no RGB24). Note that some modes can be similar to Overlay, but the two filters are still different. Overlay accepts mask clip, Layer would use existing A plane. Overlay "blend" is Layer "add", Overlay "add" is different. Lighten and darken is a bit different in Overlay. Layer has "placement" parameter for proper mask positioning over chroma. - Support for all 8-32 bit Y and planar YUV/YUVA and planar RGB/RGBA formats When overlay clip is YUVA and RGBA, then alpha channels of overlay clip are used (similarly to RGB32 and RGB64 formats) Non-alpha plane YUV/planar RGB color spaces act as having a fully transparent alpha channel (like the former YUY2 only working mode) Note: now if destination is YUVA/RGBA, the overlay clip also has to be Alpha-aware type. Now A channel is not updated for YUVA targets, but RGBA targets do get the Alpha updated (like the old RGB32 mode did) Todo: allow non-Alpha destination and Alpha-Overlay - New parameter: float "opacity" (0.0 .. 1.0) optionally replaces the previous "level". Similar to "opacity" in "Overlay" For usage of "level" see http://avisynth.nl/index.php/Layer "opacity" parameter is bit depth independent, one does not have to fiddle with it like had to with level (which was maxed with level=257 when RGB32 but level=256 for YUY2/YUV) - threshold parameter (used for lighten/darken) is autoscaled. Keep it between 0 and 255, same as it was used for 8 bit videos. - new parameter: string "placement" default "mpeg2". Possible values: "mpeg2" (default), "mpeg1". Used in "mul", "darken" and "lighten", "add" and "subtract" modes with planar YUV 4:2:0 or 4:2:2 color spaces (not available for YUY2) in order to properly apply luma/overlay mask on U and V chroma channels. - Fix some out-of-frame memory access in YUY2 C code - Fix: Add proper rounding for add/subtract/lighten/darken calculations. (YUY2, RGB32, 8 bit YUV and 8 bit Planar RGB) - Fix: "lighten" and "darken" gave different results between yuy2 and rgb32 when Threshold<>0 Fixed "darken" for RGB32 when Threshold<>0 Fixed "lighten" and "darken" for YUY2 when Threshold<>0 All the above was done by specification: Add: "Where overlay is brigher by threshold" => e.g. Where overlay is brigther by 10 => Where overlay > src + 10 Calculation: alpha_mask = ovr > (src + thresh) ? level : 0; Add: "Where overlay is darker by threshold" => e.g. Where overlay is darker by 10 => Where overlay < src - 10 Calculation: alpha_mask = ovr < (src - thresh) ? level : 0; The only correct case of the above was "lighten" for RGB32, even in Classic Avisynth. Note: Threshold=0 was O.K. - (Just an info: existing lighten/darken code for YUY2 is still not correct, messing up chroma a bit, since it uses weights from even luma positions (0,2,4,...) for U, and odd luma positions (1,3,5,...) for V) - Avisynth C interface header (avisynth_c.h): - cosmetics: functions regrouped to mix less AVSC_API and AVSC_INLINE, put together Avisynth+ specific stuff - cosmetics: remove unused form of avs_get_rowsize and avs_get_height (kept earlier for reference) - use #ifndef AVSC_NO_DECLSPEC for AVSC_INLINE functions which are calling API functions - define alias AVS_FRAME_ALIGN as FRAME_ALIGN (keep the AVS_xxxx naming convention) - dynamic loader (avs_load_library) uses fallback mechanism for non-existant Avisynth+ specific functions, in order to have Avisynth+ specific API functions safely callable even when connected to classic Avisynth DLL The smart fallback mechanism for Avisynth+ specific functions ensures that if the functions are not loadable, they will work in a classic Avisynth compatible mode: Example#1: e.g. avs_is_444 will call the existing avs_is_yv24 instead Example#2: avs_bits_per_component will return 8 for all colorspaces (Classic Avisynth supports only 8 bits/pixel) Affected functions and mapping: avs_is_rgb48, avs_is_rgb64, avs_is_yuv444p16, avs_is_yuv422p16, avs_is_yuv420p16, avs_is_y16: returns false (0) avs_is_yuv444ps, avs_is_yuv422ps, avs_is_yuv420ps, avs_is_y32: returns false (0) avs_is_yuva, avs_is_planar_rgb, avs_is_planar_rgba: returns false (0) avs_is_444: calls avs_is_yv24 instead avs_is_422: calls avs_is_yv16 instead avs_is_420: calls avs_is_yv12 instead avs_is_y: calls avs_is_y8 instead avs_num_components: returns 1 for y8, 4 for RGB32, 3 otherwise avs_component_size: returns 1 (1 bytes) avs_bits_per_component: returns 8 (8 bits) - filter "Version": update year, removed avs-plus.net link - Updated: TimeStretch plugin with SoundTouch 2.1.3 (as of 07.Jan 2019) - Source/Build system - rst documentation update (qyot27) in distrib\docs\english\source\avisynthdoc\contributing\compiling_avsplus.rst - GCC-MinGW build (huge thanks to qyot27) - various source fixes for MinGW builds, Avisynth core compiles fine, except external plugins Shibatch and DirectShowSource - CMakeLists.txt updates (user selecteble CPU arch, MinGW things) - PluginManager.cpp: [MSVC|GCC] should only load [MSVC|GCC] plugins (qyot27) This commit simply tells GCC builds of AviSynth to use the value of the PluginDir+GCC registry entry to find plugins, and ignore PluginDir and PluginDir+. Vice-versa for MSVC builds. C plugins are an exception to this, since those can be loaded with either MSVC- or GCC-built AviSynth+. - GCC 8.3 support (see in distrib\docs\english\source\avisynthdoc\contributing\compiling_avsplus.rst) - Howto: MSYS2/GCC: for windows based build environment see step-by-step instructions: https://github.com/orlp/dev-on-windows/wiki/Installing-GCC--&-MSYS2 - CMake: choose generator "MinGW Makefiles" from CMakeGUI or del CMakeCache.txt "c:\Program Files\CMake\bin\cmake.exe" -G "MinGW Makefiles" . then build with mingw32-make -f makefile - todo: fix plugin DLL names - CMake: Visual Studio 2019 generator support, please update to CMake to 3.14.1 - Clang (LLVM) support with Visual Studio 2019 (16.0) / 2017 (15.9.9) (Latest Clang is 8.0 at the moment) - CMakeLists.txt update - Additional source fixes. - Source lines for different processor targets (SSSE3 and SSE4.1) are now separated and are compiled using function attributes. Clang howto: - Install LLVM 8.0 or later (http://releases.llvm.org/download.html, Windows pre-built libraries) - Install Clang Power Tools & LLVM Compiler Toolchain (thx fuchanghao) - https://marketplace.visualstudio.com/items?itemName=caphyon.ClangPowerTools - https://marketplace.visualstudio.com/items?itemName=LLVMExtensions.llvm-toolchain - (When using CMakeGUI) After Configure/Specify generator for this project, type LLVM for "Optional Toolset to use (-T option)" - Known issues: - compiling Avisynth only .lib is generated (used for C api), .exp is missing - When generating assembler output linking or other errors can happen - LLVM 8.0 has sub-optimal avg_epu8 intrinsic "optimization", which is fixed in LLVM 9.0 (e.g. in snapshot build 21 June 2019) 20181220 r2772 -------------- - Fix: Expr: possible Expr x64 crash under specific memory circumstances - Fix: Expr: safer code for internal variables "Store and pop from stack" (see: Internal variables at http://avisynth.nl/index.php/Expr) 20181218 r2768 -------------- - 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. (Assignment within an expression) Examples: w := h := 256 b := blankclip(width=w * 2, height = h * 3, length=40, pixel_type="yv12") bm = blankclip(width=w, height = w).letterbox(2,0,2,0, color=$ff) b for(j = 0, 1, 1) { for(i = 0, 1, 1) { e = 0 + i * 16 + j * 16 * 4 ce = string(e) c = bm.subtitle("Y = 0x" + hex(e) + " " + ce) eval("c" + string(i) + string(j) + " := c") b := b.overlay(c, x = i * w, y = j * h) } } cx = c00.trim(0, 9) + c01.trim(0, 9) + c10.trim(0, 9) + c11.trim(0, 9) b := overlay(cx, x = 0, y = w * 2) /* defined NEW_AVSVALUE at build */ array = [99, 101, "303", cnt := 4] for(j = 0, cnt - 1, 1) { b := subtitle(string(array[ind := j]), x = 100, y=(j+1) * 20) } g := b.tstfunc(kf := "first", ks := "second") g := subtitle((s := 4) > 0 ? t := "left" : t := "right", y = 100) g := subtitle(string(s) + " " + t + " " + ks, y = 150) eval("""h := g.subtitle("G", x=200, y = 20)""") h.subtitle("H " + string(ind), x = 300, y = 20) function tstfunc(c, d, e) { if (f := 1 < 2) { c.subtitle(string(f) + e, y = 50) } else { c.subtitle(d, y = 50) } } 20180702 r2728 -------------- - New: Expr: implement 'clip' three operand operator like in masktools2 Description: clips (clamps) value: x minvalue maxvalue clip -> max(min(x, maxvalue), minvalue) - New: Expr: Parameter "clamp_float" True: clamps 32 bit float to valid ranges, which is 0..1 for Luma or for RGB color space and -0.5..0.5 for YUV chroma UV channels Default false, ignored (treated as true) when scale_inputs scales float - New: Expr: parameter "scale_inputs" (default "none") Autoscale any input bit depths to 8-16 bit for internal expression use, the conversion method is either full range or limited YUV range. Feature is similar to the one in masktools2 v2.2.15 The primary reason of this feature is the "easy" usage of formerly written expressions optimized for 8 bits. Use - "int" : scales limited range videos, only integer formats (8-16bits) to 8 (or bit depth specified by 'i8'..'i16') - "intf": scales full range videos, only integer formats (8-16bits) to 8 (or bit depth specified by 'i8'..'i16') - "float" or "floatf" : only scales 32 bit float format to 8 bit range (or bit depth specified by 'i8'..'i16') - "all": scales videos to 8 (or bit depth specified by 'i8'..'i16') - conversion uses limited_range logic (mul/div by two's power) - "allf": scales videos to 8 (or bit depth specified by 'i8'..'i16') - conversion uses full scale logic (stretch) - "none": no magic Usually limited range is for normal YUV videos, full scale is for RGB or known-to-be-fullscale YUV By default the internal conversion target is 8 bits, so old expressions written for 8 bit videos will probably work. This internal working bit-depth can be overwritten by the i8, i10, i12, i14, i16 specifiers. When using autoscale mode, scaleb and scalef keywords are meaningless, because there is nothing to scale. How it works: - This option scales all 8-32 bit inputs to a common bit depth value, which bit depth is 8 by default and can be set to 10, 12, 14 and 16 bits by the 'i10'..'i16' keywords For example: scale_inputs="all" converts any inputs to 8 bit range. No truncation occurs however (no precision loss), because even a 16 bit data is converted to 8 bit in floating point precision, using division by 256.0 (2^16/2^8). So the conversion is _not_ a simple shift-right-8 in the integer domain, which would lose precision. - Calculates expression (lut, lut_xy, lut_xyz, lut_xyza) - Scales the result back to the original video bit depth. Clamping (clipping to valid range) and converting to integer occurs here. The predefined constants such as 'range_max', etc. will behave according to the internal working bit depth Warning#1 This feature was created for easy porting earlier 8-bit-video-only lut expressions. You have to understand how it works internally. Let's see a 16bit input in "all" and "allf" mode (target is the default 8 bits) Limited range 16->8 bits conversion has a factor of 1/256.0 (Instead of shift right 8 in integer domain, float-division is used or else it would lose presision) Full range 16->8 bits conversion has a factor of 255.0/65535 Using bit shifts (really it's division and multiplication by 2^8=256.0): result = calculate_lut_value(input / 256.0) * 256.0 Full scale 16-8-16 bit mode ('intf', 'allf') result = calculate_lut_value(input / 65535.0 * 255.0 ) / 255.0 * 65535.0 Use scale_inputs = "all" ("int", "float") for YUV videos with 'limited' range e.g. in 8 bits: Y=16..235, UV=16..240). Use scale_inputs = "allf" (intf, floatf) for RGB or YUV videos with 'full' range e.g. in 8 bits: channels 0..255. When input is 32bit float, the 0..1.0 (luma) and -0.5..0.5 (chroma) channel is scaled to 0..255 (8 bits), 0..1023 (i10 mode), 0..4095 (i12 mode), 0..16383(i14 mode), 0..65535(i16 mode) then back. Warning#2 One cannot specify different conversion methods for converting before and after the expression. Neither can you specify different methods for different input clips (e.g. x is full, y is limited is not supported). - Fix: Expr: expression string order for planar RGB is properly r-g-b like in original VapourSynth version, instead of counter-intuitive g-b-r. - Fix: Expr: check subsampling when a different output pixel format is given - Fix: ColorYUV: round to avoid green cast on consecutive TV<>PC - Enhanced: Limiter to work with 32 bit float clips - Enhanced: Limiter new parameter bool 'autoscale' default false. If set, minimum/maximum luma/chroma values are treated as they were in 8 bit range (but non-integer values are allowed), limiter will autoscale it. Default: does not scale at all, parameters are used as-is. Parameters now are of float type to handle 32 bit float values. - New: function bool VarExist(String variable_name) Checks if a variable exists Returns true if variable exists even if it holds 'Undefined', false otherwise - Fix: RGBAdjust memory leak when used in ScriptClip - Enhanced: RGBAdjust new parameter: conditional (like in ColorYUV) The global variables "rgbadjust_xxx" with xxx = r, g, b, a, rb, gb, bb, ab, rg, gg, bg, ag are read each frame, and applied. It is possible to modify these variables using FrameEvaluate or ConditionalReader. - Enhanced: RGBAdjust: support 32 bit float ('analyze' not supported, 'dither' silently ignored) - Enhanced: AviSource to support more formats with 10+ bit depth. http://avisynth.nl/index.php/AviSource When pixel_type is not specified or set to "FULL", AviSource will try to request the formats one-by-one in the order shown in the table below. When a classic 'pixel_type' shares more internal formats (such as YUV422P10 first tries to request the v210 then P210 format) you can specify one of the specific format directly. Note that high bit-depth RGBP is prioritized against packed RGB48/64. The 'FourCCs for ICDecompressQuery' column means that when a codec supports the format, it will serve the frame in that one, Avisource then will convert it to the proper colorspace. Full support list (* = already supported): 'pixel_type' Avs+ Format FourCC(s) for ICDecompressQuery YV24 YV24 *YV24 YV16 YV16 *YV16 YV12 YV12 *YV12 YV411 YV411 *Y41B YUY2 YUY2 *YUY2 RGBP10 RGBP10 G3[0][10] r210 R10k r210 RGBP10 r210 R10k RGBP10 R10k RGBP RGBP10 G3[0][10] r210 R10k RGBP12 G3[0][12] RGBP14 G3[0][14] RGBP16 G3[0][16] RGBAP10 G4[0][10] RGBAP12 G4[0][12] RGBAP14 G4[0][14] RGBAP16 G4[0][16] RGB32 RGB32 *BI_RGB internal constant (0) with bitcount=32 RGB24 RGB24 *BI_RGB internal constant (0) with bitcount=24 RGB48 RGB48 BGR[48] b48r RGB64 RGB64 *BRA[64] b64a Y8 Y8 Y800 Y8[32][32] GREY Y Y8 Y800 Y8[32][32] GREY Y10 Y1[0][10] Y12 Y1[0][12] Y14 Y1[0][14] Y16 Y1[0][16] YUV422P10 YUV422P10 v210 P210 v210 YUV422P10 v210 P210 YUV422P10 P210 YUV422P16 YUV422P16 P216 P216 YUV422P16 P216 YUV420P10 YUV420P10 P010 P010 YUV422P10 P010 YUV420P16 YUV420P16 P016 P016 YUV422P16 P016 YUV444P10 YUV444P10 v410 v410 YUV444P10 v410 - Changed (finally): 32bit float YUV colorspaces: zero centered chroma channels. U and V channels are now -0.5..+0.5 (if converted to full scale before) instead of 0..1 Note: filters that relied on having the U and V channel center as 0.5 will fail. Why: the old UV 0..1 range was a very-very early decision in the high-bitdepth transition project. Also it is now compatible with z_XXXXX resizers (zimg image library, external plugin at the moment). - New function: bool IsFloatUvZeroBased() For plugin or script writers who want to be compatible with pre r2672 Avisynth+ float YUV format: Check function availablity with FunctionExists("IsFloatUvZeroBased"). When the function does not exists, the center value of 32 bit float U and V channel is 0.5 When IsFloatUvZeroBased function exists, it will return true (always for official releases) if U and V is 0 based (+/-0.5) - Fix: RGB64 Turnleft/Turnright (which are also used in RGB64 Resizers) - Fix: Rare crash in FrameRegistry - Enhanced: Allow ConvertToRGB24-32-48-64 functions for any source bit depths - Enhanced: ConvertBits: allow fulls-fulld combinations when either clip is 32bits E.g. after a 8->32 bit fulls=false fulld=true: Y: 16..235 -> 0..1 U/V: 16..240 -> -0.5..+0.5 Note: now ConvertBits does not assume full range for YUV 32 bit float. Default values of fulls and fulld are now true only for RGB colorspaces. - Fix: couldn't see variables in avsi before plugin autoloads (colors_rgb.avsi issue) - Fix: LoadVirtualdubPlugin: Fix crash on exit when more than one instances of a filter was used in a script - New: LoadVirtualdubPlugin update: - Update from interface V6 to V20, and Filtermod version 6 (partial) - VirtualDub2 support with extended colorspaces Allow RGB24, RGB48, RGB64 besides RGB32 AutoConvert 8 bit Planar RGB to/from RGB24, RGBPA to/from RGB32 (lossless) AutoConvert RGB48 and 16 bit Planar RGB(A) to/from RGB64 (lossless) Support YUV(A) 8 bits: YV12, YV16, YV24, YV411, YUVA420P8, YUVA422P8, YUVA444P8 Support YUV(A) 10-16 bits (properly set "ref_x" maximum levels, no autoconvert) - Supports prefetchProc2 callback (API >= V14 and prefetchProc2 is defined) for multiple input frames from one input clip PrefetchFrameDirect and PrefetchFrame are supported. PrefetchFrameSymbolic not supported - Supports prefetchProc callback (API >= V12 and prefetchProc is defined) - Supports when filter changes frame count of the output clip - Extra filter parameter added at the end of filter's (unnamed) parameter list Imported Virtualdub filters are getting and extra named parameter to the end: String [rangehint] This parameter can tell the filter about a YUV-type clip colorspace info Allowed values: "rec601": limited range + 601 "rec709": limited range + 709 "PC.601": full range + 601 "PC.709": full range + 709 "" : not defined (same as not given) Parameter will be ignored when clip is non-YUV How it works: the hint will _not_ change the internal VirtualDub colorspace constant (e.g. kPixFormat_YUV420_Planar -> kPixFormat_YUV420_Planar_709 will not happen). Instead the base color space is kept and colorSpaceMode and colorRangeMode will set in PixmapLayout.formatEx. Filter can either use this information or not, depending on supported API version and its implementation. E.g. Crossfade(20,30) -> Crossfade(20,30,"rec601") though this specific filter won't use it. - New function: BuildPixelType Creates a video format (pixel_type) string by giving a colorspace family, bit depth, optional chroma subsampling and/or a template clip, from which the undefined format elements are inherited. "[family]s[bits]i[chroma]i[compat]b[oldnames]b[sample_clip]c" string family: YUV, YUVA, RGB, RGBA, Y int bits: 8, 10, 12, 14, 16, 32 string chroma: for YUV(A) 420,422,444,411. Ignored for RGB(A) and Y bool compat (default false): returns packed rgb formats for 8/16 bits (RGB default: planar RGB) bool oldnames (default false): returns YV12/YV16/YV24 instead of YUV420P8/YUV422P8/YUV444P8 clip sample_clip: when supported, its format is overridden by specified parameters (e.g. only change bits=10) Example#1: define YUV 444 P 10 family = "YUV" bits = 10 chroma = 444 compat = false oldformat = false s = BuildPixelType(family, bits, chroma, compat, oldformat) BlankClip(width=320,height=200,length=len,pixel_type=s,color=$008080).Info() Example#2: Change only the bit depth of the format to 16 newbits = 16 c = last s = BuildPixelType(bits=newbits, sample_clip=c) BlankClip(width=320,height=200,length=len,pixel_type=s,color=$008080).Info() - Source: move to c++17, 'if constexpr' requires. Use Visual Studio 2017 (or GCC 7?). CMakeLists.txt changed. - Source: C api: AVSC_EXPORT to dllexport in capi.h for avisynth_c_plugin_init - Source: C api: avs_is_same_colorspace VideoInfo parameters to const - Project struct: changelog to git. - Include current avisynth header files and def/exp file in installer, when SDK is chosen 20180328 r2664 -------------- - Fix: YUY2 Sharpen overflow artifacts - e.g. Sharpen(0.6) - Fix: Levels: 32 bit float shift in luma - Fix: Merge sse2 for 10-14bits (regression) - Fix: AVX2 resizer possible access violation in extreme resizes (e.g. 600->20) - Fix: 32bit float PlanarRGB<->YUV conversion matrix - Fix: VfW: fix b64a output for OPT_Enable_b64a=true - Enhanced: VfW output P010 and P016 conversion to SSE2 (VfW output is used by VirtualDub for example) - Enhanced: ColorYUV: recalculate 8-16 bit LUT in GetFrame only when changed frame-by-frame (e.g. in autowhite) - Enhanced: ConvertBits 32->8 sse2/avx2 and 32->10..16 sse41/avx2 (8-15x speed) Not included, preliminary for the near future: - Big change: 32 bit float YUV formats, U and V are now zero based. Internally YUV 32 bit float chroma center became 0.0 (the neutral value which is 128 in the 8-bit world) Like in VapourSynth or in avsresizer using z.lib image library. 'Expr' changes are affecting built-in constants/operators when used in chroma plane of a 32bit clip. - 'cmin', 'cmax' return the zero-based shifted versions of the 16 and 240 (8 bit) values - For U and V planes, constant 'range_half' results in 0.0 instead of the old 0.5 - 'scaleb' will also give zero-based result when found in an expression for chroma plane (e.g. for a 32 bit float clip the '128 scaleb' will result in 0.0 instead of 128/255 for U and V planes) But 'scalef' when the target or source of the constant conversion is 32bits, remains independent from the plane type. - 'range_max' is 0.5 for 32 bit float chroma - new constant 'range_min', which is -0.5 for 32 bit float chroma, (0 otherwise) Additional warning: when you move 32bit float U or V plane to Y using CombinePlane, you have to be sure that your filters do not rely on this new Y plane being in 0..1 range. Or else convert it by using Expr("x 0.5 +") to the 0..1 range Similarly: ExtractU and ExtractV will simply return the unaltered chroma planes, which are now zero-centered 20180302 r2636 -------------- - Fix: Blur/Sharpen crashed when YUY2.width<8, RGB32.width<4, RGB64.width<2 - ColorYUV: don't apply TV range gamma for opt="coring" when explicit "PC->TV" is given - ColorbarsHD: 32bit float properly zero (0.5)-centered chroma 20180301 r2632 -------------- - Fix: IsInterleaved returned false for RGB48 and RGB64 (raffriff42) - Fix: SubTitle for Planar RGB/RGBA: wrong text colors (raffriff42) - Fix: Packed->Planar RGB conversion failed on SSE2-only computers (SSSE3 instruction used) - Enhanced: Blur, Sharpen AVX2 for 8-16 bit planar colorspaces (>1.35x speed on i7-7770) SSE2 for 32 bit float formats (>1.5x speed on i7-7770) - Fix: Resizers for 32 bit float rare random garbage on right pixels (simd code NaN issue) - Enhanced: Completely rewritten 16bit and float resizers, much faster (and not only with AVX2) - Enhanced: 8 bit resizers: AVX2 support - Enhanced: Speed up converting from RGB24/RGB48 to Planar RGB(A) - SSSE3, approx. doubled fps - New: ConvertFPS supports 10-32 bits, planar RGB(A), YUV(A) - New script function: int BitSetCount(int[, int, int, ...]) Function accepts one or more integer parameters Returns the number of bits set to 1 in the number or the total number of '1' bits in the supplied integers. - Cherry-picking from StainlessS' great RT_xxxx collection/and raffriff42 utils - Modded script function: Hex(int , int "width"=0) - New "width" parameter - result is in uppercase Width is 0 to 8, the _minimum_ width of the returned string. (8 hex digit is the max of Avisynth32 bit integer) When width is 0 or not supplied then string length is a minimum needed. Function now returns hex string in uppercase, instead of lowercase. Example: Hex(255,4) returns "00FF". - Modded script function: HexValue(String, "pos"=1) - new pos parameter Returns an int conversion of the supplied hexadecimal string. Conversion will cease at the first non legal number base digit, without producing an error Added optional pos arg default=1, start position in string of the HexString, 1 denotes the string beginning. Will return 0 if error in 'pos' ie if pos is less than 1 or greater than string length. - Modded script function: ReplaceStr(String, String, String[, Boolean "sig"=false]) - New parameter: sig for case insensitive search (Default false: exact search) The uppercase/lowercase rules come from the current active code page of the OS. - New script functions: TrimLeft, TrimRight, TrimAll for removing beginning/trailing whitespaces from a string. Whitespaces: Tab (9), space (32), nbsp (160) - New in ColorYUV: New parameter: bool f2c="false". When f2c=true, the function accepts the Tweak-like parameters for gain, gamma and contrast E.g. use 0/0.5/1.0/1.5/2.0/3.0 instead of -256/-128/0/128/256/512 - New/Fixed in ColorYUV: Parameter "levels" accepts "TV". (can be "TV->PC", "PC->TV", "PC->TV.Y") Now gamma calculation is TV-range aware when either - levels is "TV->PC" or - coring = true or - levels is "TV" (new - no level conversion but gamma will know proper handling) Previously gamma was properly calculated only for PC range. - New in ColorYUV: 32 bit float support. - 32 bit float uses the Expr filter (8-16 bits is LUT-based). The expression is dynamically assembled for each plane, internal precision is float. - One can specify bits=32 when showyuv=true -> test clip in YUV420PS format For 32 bit clips "loose min" and "loose_max" (omitting the extreme 1/256 population from dark and bright pixels) statistics are computed by splitting the 0..1 into 65536 uniform ranges. - Modded: remove "scale" parameter from ConvertBits. It was introduced at the very beginning of the 10+bit development, for 32bit float conversion - never used - Enhanced: VfW: exporting Y416 (YUV444P16) to SSE2. - 8-16 bit YUV chroma to 32 bit float: keep middle chroma level (e.g. 128 in 8 bits) at 0.5. Calculate chroma as (x-128)/255.0 + 0.5 and not x/255.0 (Note: 32 bit float chroma center will be 0.0 in the future) - New: Histogram parameter "keepsource"=true (raffriff42) keepsource = false returns only the Histogram w/o the original picture. Affects "classic", "levels" and "color", "color2", ignored (n/a) for the other modes - New: Histogram type "color" to accept 8-32bit input and "bits"=8,9,..12 display range - New: Histogram parameter "markers"=true When markers = false: For "classic": no "half" level line and no invalid luma zone coloring For "levels": no "half" dotted line, no coloring (neither for YUV nor for RGB) Ignored for the others at the moment. 20171226 r2580 ---------------- - Fix (workaround): Merge: Visual Studio 2017 15.5.1/2 generated invalid AVX2 code The x86 path of Merge Average was crashing due to bad code generation in the 8 bit version. Seems that thought Visual Studio Team was proudly announcing optimizations in their compiler (15.5.x line), it had victims. - Fix: Temporalsoften 10-14 bits: an SSE 4.1 instruction was used for SSE2-only CPU-s (Illegal Instruction on Athlon XP) 20171219 r2574 ---------------- - Fix: MaskHS created inverse mask. Regression after r2173 - Build: changed avisynth.h, strict C++ conformity with Visual Studio 2017 /permissive- flag - Installer (finally) - Expr: - new: Indexable source clip pixels by relative x,y positions like x[-1,1] - new functions: sin cos tan asin acos atan - new operator: % (modulo) - new: Variables: uppercase letters A..Z for storing and reuse temporary results, frequently used computations. - new: predefined expr variables 'frameno', 'time', 'width', 'height' - fix: jitasm code generation at specific circumstances 20171115 r2544 - Expr: fix "scalef" for 10-16 bits - Expr optimization: eliminate ^1 +0 -0 *1 /1 20171114 r2542 - New filter: Expr Ported from Vapoursynth, with a lot of additional tweaks e.g. AVX2, recognize constant fill, spatial absolute and relative coordinates as input, recognize plane copy, no GetFrame for unused clips, converts ^2, ^3, ^4 into faster multiplication, converts x^0.5 into sqrt(x), borrow specific syntax elements from masktools2 (scaling, operators - but not all of them) to have partial compatibility in widely used existing expression strings (see readme.txt) clip Expr(clip c[,clip c2, ...], string expr [, string expr2[, string expr3[, string expr4]]] [, string format] [, bool optSSE2][, bool optAVX2][, bool optSingleMode]) - Add: Levels: 32 bit float format support - Fix: RGB (full scale) conversion: 10-16 bits to 8 bits rounding issue; pic got darker in repeated 16<->8 bit conversion chain - Fix: ConvertToY: remove unnecessary clamp for Planar RGB 32 bit float - Fix: RGB ConvertToY when rec601, rec709 (limited range) matrix. Regression since r2266 - Optimized: Faster RGB (full scale) 10-16 bits to 8 bits conversion when dithering - Other: Default frame alignment is 64 bytes (was: 32 bytes). (independently of AVX512 support) - Build: Built with Visual Studio 2017, v141_xp toolset Note that DLL will work When you have VS2015 Update 3 redistributable. Download Visual Studio 2017 Redistributable from here (replaces and compatible with VS2015 redist) X64: https://go.microsoft.com/fwlink/?LinkId=746572 x86: https://go.microsoft.com/fwlink/?LinkId=746571 - Experimental x64 builds for test (internal offsets from int to size_t) - Source: avisynth_c.h (C interface header file) changed: Optional define SIZETMOD. Experimental. Offsets are size_t instead of int (x64 is different!) Fix: avs_get_row_size calls into avs_get_row_size_p, instead of direct field access Fix: avs_get_height calls into avs_get_row_size_p, instead of direct field access. 20170629 r2508 - Fix TemporalSoften: threshold < 255 (probably since r1576) 20170608 r2506 - Fix CombinePlanes: feeding YV16 or YV411 target with Y8 sources 20170603 r2504 - fix XP support broken in r2502 20170602 r2502 - fix: (Important!) MT_SERIALIZED mode did not always protect filters (regression since r2069) Such filters sometimes were called in a reentrant way (like being MT_NICE_FILTER), which possibly resulted in using their internal buffers parallel. - Fix: ImageWriter crash when no '.' in provided filename - Fix: Overlay: correct masked blend: keep exact clip1 or clip2 pixel values for mask extremes 255 or 0. Previously 0 became 1 for zero mask, similarly 255 changed into 254 for full transparency (255) mask - New: script functions: StrToUtf8, StrFromUtf8: Converting a 8 bit (Ansi) string to UTF8 and back. - New: PluginManager always throws error on finding wrong bitness DLL in the autoload directories - Modified: increased x64 default MemoryMax from 1GB to 4GB, but physicalRAM/4 is still limiting - Modified: allow conversions between RGB24/32/48/64 (8<->16 bits) w/o ConvertBits - Added VS2017 and v141_xp to CMakeList.txt 20170529 r2489 - fix: memory leak in CAVIStreamSynth (e.g. feeding vdub) - fix: ConvertToY for RGB64 and RGB48 20170528 r2487 - Blur, Sharpen 10-16 bits planar and RGB64: SSE2/SSE4 (2x-4x speed) - New script function: int GetProcessInfo([int type = 0]) Without parameter or type==0 the current bitness of Avisynth DLL is returned (32 or 64) With type=1 the function can return a bit more detailed info: -1: error, can't establish 0: 32 bit DLL on 32 bit OS 1: 32 bit DLL on 64 bit OS (WoW64 process) 2: 64 bit DLL - Fix: Blur width=16 (YV12 width=32) - Fix: Overlay Lighten: artifacts when base clip and overlay clip have different widths (regression since r2290) - Fix: YUY2 HorizontalReduceBy2 did nothing if target width was not mod4 - ImageReader: 16 bit support; "pixel_type" parameter new formats "RGB48", "RGB64" and "Y16" - ImageWriter: 16 bit support; save RGB48, RGB64, Y16, planar RGB(A) 8 and 16 bit formats (note: greyscale through devIL can be corrupt with some formats, use png) - ImageWriter: flip greyscale images vertically (except "raw" format) - SubTitle: new parameter "font_filename" allows using non-installed fonts - (project can be compiled using gcc) - Allows opening unicode filenames through VfW interface (virtualdub, MPC-HC) - Script function Import: new parameter bool "utf8" to treat the filenames as UTF8 encoded (not the script text!) - SubTitle: new parameter bool "utf8" for drawing strings encoded in UTF8. Title="Cherry blossom "+CHR($E6)+CHR($A1)+CHR($9C)+CHR($E3)+CHR($81)+CHR($AE)+CHR($E8)+CHR($8A)+CHR($B1) SubTitle(Title,utf8=true) - New script functions: ScriptNameUtf8(), ScriptFileUtf8(), ScriptDirUtf8(), they return variables $ScriptNameUtf8$, $ScriptFileUtf8$ and $ScriptDirUtf8$ respectively Knows issues: - Filters with MT_SERIALIZED sometimes can get called in a reentrant way - Runtime Script functions under MT 20170316 r2455 - Fix: IsY() script function returned IsY8() (VideoInfo::IsY was not affected) - New: ConvertBits, dither=1 (Floyd-Steinberg): allow any dither_bits value between 0 and 8 (0=b/w) 20170310 r2440 - Fix Merge for float formats - Fix error text formatting under wine (_vsnprintf_l issue) - Fix Regression: YUY2 UToY copied V instead of U, since August, 2016 (v2150) - faster Merge: float to sse2 (both weighted and average) - faster ordered dither to 8bit: SSE2 (10x speed) - ColorBars allows any 4:2:0, 4:4:4 formats, RGB64 and all planar RGB formats - ColorBarsHD accepts any 4:4:4 formats - Dithering: Floyd-Steinberg Use convertBits parameter dither=1: Floyd-Steinberg (was: dither=0 for ordered dither) - Dithering: parameter "dither_bits" For dithering to lower bit depths than the target clip format Usage: ConvertBits(x, dither=n [, dither_bits=y]) - ordered dither: dither_bits 2, 4, 6, ... but maximum difference between target bitdepth and dither_bits is 8 - Floyd-Steinberg: dither_bits 1, 2, 4, 6, ... up to target bitdepth - 2 (Avisynth+ low bitdepth, Windows 3.1 16 bit feeling I was astonished that dither_bits=6 still resulted in a quite usable image) - Dithering is allowed from 10-16 -> 10-16 bits (was: only 8 bit targets) - Dithering is allowed while keeping original bit-depth. clip10 = clip10.ConvertBits(10, dither=0, dither_bits=8) (you still cannot dither from 8 or 32 bit source) - ConditionalFilter syntax extension like Gavino's GConditional: no "=" "true" needed - Revert: don't give error for interlaced=true for non 4:2:0 sources (compatibility, YATTA) - CombinePlanes: silently autoconvert packed RGB/YUY2 inputs to planar - ConvertBits: show error message on YV411 conversion attempt: 8 bit only - ConvertBits: Don't give error message if dither=-1 (no dithering) is given for currently non-ditherable target formats - Script function: IsVideoFloat. returns True if clip format is 32 bit float. For convenience, same as BitsPerComponent()==32 - ConvertToDoubleWidth and ConvertFromDoubleWidth: RGB24<->RGB48, RGB32<->RGB64 - New MT mode: MT_SPECIAL_MT. Specify it for MP_Pipeline like filters, even if no Prefetch is used (MP_Pipeline issue, 2 fps instead of 20) 20170202 r2420 - CombinePlanes: When there is only one input clip, zero-cost BitBlt-less subframes are used, which is much faster. e.g.: casting YUV to RGB, shuffle RGBA to ABGR, U to Y, etc.. Target planes that are not specified, preserve their content. Examples: combineplanes(clipRGBP, planes="RGB",source_planes="BGR") # swap R and B combineplanes(clipYUV, planes="GBRA",source_planes="YUVA",pixel_type="RGBAP8") # cast YUVA to planar RGBA combineplanes(clipYUV, planes="Y",source_planes="U",pixel_type="Y8") # extract U - fix: SubframePlanarA (available in IScriptEnvironment2) - faster: Difference-type conditional functions: Simd for 10-16 bits - Fix: MinMax-type conditional functions (min, max, median): return float value for float clips - ConvertToPlanarRGB(A): PlanarRGB <-> PlanarRGBA is now allowed - ConvertToPlanarRGB(A): YUY2 source is now allowed (through automatic ConvertToRGB proxy) - faster: RemoveAlphaPlane (subframe instead of BitBlt copy) - Overlay: "Blend" native greyscale mode: process y plane only w/o conversion - Overlay: automatic use444=false for "blend"/"luma"/"chroma" for inputs: 420/422/444 and any RGB, lossless Planar RGB intermediate for PackedRGB Overlay/mask auto-follows input clip format. For compatibility: when greymask=true (default) and mask is RGB then mask source is the B channel - faster: RGB48->RGB64 SSSE3 (1,6x), RGB64->RGB48 SSSE3 (1.5x speed) - faster: RGB24,RGB48->PlanarRGB: uses RGB32/64 intermediate clip - Histogram "levels": allow RGB24/32/48/64 input. Display R, G and B channels instead of Y, U and V Reminder 1: "levels" for Planar RGB was working already Reminder 2: Histogram "levels" and "Classic" allows bits=xx parameter, xx=8..12 If "bits" is specified then Histogram is drawn with 9..12 bits precision. Get a wide monitor though :) - ConvertBits: new parameters, partially for the future. bool fulls, bool fulld For YUV and greyscale clips the bit-depth conversion uses simple bit-shifts by default. YUV default is fulls=false RGB is converted as full-stretch (e.g. 0..255->0..65535) RGB default is fulls=true If fulld is not specified, it takes the value of fulls. Use case: override greyscale conversion to fullscale instead of bit-shifts Note 1: conversion from and to float is always full-scale Note 2: alpha plane is always treated as full scale Note 3: At the moment you cannot specify fulld to be different from fulls. 20170119 r2397 - TemporalSoften: Planar RGB support - TemporalSoften: much faster average mode (thres=255) radius=1 +70%, radius=2 +45%, 16bit: generally 7-8x speed (SSE2/4 instead of C) - SeparateColumns: 10-16bit,float,RGB48/64 - WeaveColumns: 10-16bit,float,RGB48/64,PlanarRGB(A) - AddAlphaPlane: fix function parameter type list, clip type did not work - Internals: add SubframePlanarA to IScriptEnvirontment2 for frames with alpha plane - SwapUV: YUVA support - ConvertToRGB32/64: copy alpha from YUVA - SeparateRows,SeparateFields: PlanarRGB(A),YUVA support - WeaveRows: PlanarRGB(A), YUVA - Weave (fields,frames): YUVA,PlanarRGB(A) - Crop: Fast crop possible for frames with alpha plane (subframe) - AddBorders missing l/r/top/bottom vs. subsampling check for YUVA - Fix: YUVA->PlanarRGBA and YUVA42x->444 missing alpha plane copy - YUV444->RGB48/64: fast intermediate PlanarRGB(A) then RGB48/64 (not C path) - RGB48/64->YUV4xx target: Planar RGB intermediate (instead of C, 10x faster) 20170111 r2380 - Overlay: Merge the source of Chroma and Luma modes into Blend mode Modes Blend,Luma and Chroma now support all bit depths and 444 conversionless (use444=false) mode - Overlay: fix SSE2 Blend for mask+opacity for 10-16 bits - VfW: (vdubmod14 VfW test) Fix: YUV444P16 or YUVA444P16 to fourcc Y416 if alpha channel is present, it will we copied, else filled with FFFF Fix: VDubPlanarHack is checked only for 8 bit YUV planar sources 20170110 r2372 (vdubmod14 VfW test) - New: SSE2/SSE4 for 10-16 bit <-> 10-16 bit Planar RGB (and Alpha plane) full scale conversions (needed for automatic planar RGB -> packed RGB VfW conversions) - VfW: Fixed: Y3[10][10],Y3[10][16] fourcc's byte order New: Planar RGB(A) (MagicYUV) 10,12,14,16 bits: G3[0][10], G4[0][10], G3[0][12], G4[0][12], G3[0][14], G4[0][14], G3[0][16], G4[0][16] New: YUV444P16 to fourcc Y416 New: Automatic conversion of 12, 14 and float YUV formats to 16 bit for 4:2:0 and 4:2:2 Note: OPT_Enable_Y3_10_16 is still valid as if format was originally 16 bits New: Automatic conversion of 10, 12, 14 and float YUV formats to 16 bit for 4:4:4 New: Conversion of 10, 12, 14 and float planar RGB formats to RGB64 when global Avisynth variable Enable_PlanarToPackedRGB is true New: Conversion of 8 bit planar RGB formats to RGB24 when global Avisynth variable Enable_PlanarToPackedRGB is true New: Conversion of 8 bit planar RGBA formats to RGB32 when global Avisynth variable Enable_PlanarToPackedRGB is true Note: use OPT_VDubPlanarHack=true for YV16 and YV24 for old VirtualDub Supported formats: BRA[64],b64a,BGR[48],P010,P016,P210,P216,Y3[10][10],Y3[10][16],v210,Y416 G3[0][10], G4[0][10], G3[0][12], G4[0][12], G3[0][14], G4[0][14], G3[0][16], G4[0][16] Default format FourCCs: RGB64: BRA[64] RGB48: BGR[48] YUV420P10: P010 YUV420P16: P016 YUV422P10: P210 YUV422P16: P216 YUV444P16 and YUVA444P16: Y416 Planar RGB 10-16 bit: G3[0][10], G3[0][12], G3[0][14], G3[0][16] Planar RGBA 10-16 bit: G4[0][10], G4[0][12], G4[0][14], G4[0][16] Global variables to override default formats: OPT_Enable_V210 = true --> v210 for YUV422P10 OPT_Enable_Y3_10_10 = true --> Y3[10][10] for YUV422P10 OPT_Enable_Y3_10_16 = true --> Y3[10][16] for YUV422P16 OPT_Enable_b64a = true --> b64a for RGB64 Enable_PlanarToPackedRGB = true --> RGBP8->RGB24, RGBAP8->RGB32, all other bit depths to RGB64 20170109 r2367dev - VfW: BRA[64],b64a,BGR[48],P010,P016,P210,P216,Y3[10][10],Y3[10][16],v210 experimental!
