Changes from 3.7.2 to 3.7.3

Additions, changes

  • MIPS build support

  • New: add a sixth array element to PlaneMinMaxStats: average. Defines variable "PlaneStats_average" as well if setting variables is required.

  • "Text" halo_color allows to have both halo and shaded background when halo_color MSB=$FE

  • "Text" (#308) much nicer rendering of subsampled formats

  • "Text" (#310) Support any width of external bdf fonts (but still of fixed width)

  • "Text" (#310) Support more from the BDF standard: per-character boundary boxes and shifts

  • "Text": draw rightmost on-screen character even if only partially visible (was: not drawn at all)

  • "Text" Halo is not limited to original character matrix boundaries and is rendered on the displayed string as a whole.

  • "Text" add "left" chroma placement support; new placement parameter (left, center, auto), accept frame property _ChromaLocation hint

  • "TimeStretch" (#278) add TimeStretch overload with rational pair arguments and update SoundTouch library to v2.3.1.

  • Enhancement (#315): Show exception message as well if a v2.6-style plugin throws AvisynthError in its AvisynthPluginInit3 instead of only "'xy.dll' cannot be used as a plugin for AviSynth."

  • Fix (#327) Histogram "color2" markers. Fix right shifted 15 degree dots, fix square for bits>8

  • Feature #337: add more resizers

    • filters: SinPowerResize, SincLin2Resize, UserDefined2Resize

    • and their equivalent for the ConvertToXXXX family 'chromaresample': "sinpow", "sinclin2" and "userdefined2"

  • Feature #337: add "param1", "param2" and "param3" to ConvertToXXXX where 'chromaresample' exists (b,c,s,taps and p parameters can be set, depending on the resizer).

  • #306: Add ConvertToYUVA420, ConvertToYUVA422 and ConvertToYUVA444

  • Expr: Add remaining stack element count to "Unbalanced stack..." error message

  • Add back audio cache from classic Avisynth 2.6. Handle modes and hints on cache audio: CACHE_AUDIO, CACHE_AUDIO_NOTHING, CACHE_AUDIO_AUTO_START_OFF, CACHE_AUDIO_AUTO_START_ON, CACHE_GETCHILD_AUDIO_MODE and CACHE_GETCHILD_AUDIO_SIZE

  • Set automatic MT mode MT_SERIALIZED to ConvertToMono, EnsureVBRMP3Sync, MergeChannels, GetChannel, Normalize, MixAudio, ResampleAudio

  • Alter default VfW export (e.g. VirtualDub2) channel layout mask for 3 channels (Surround to 2.1), 4 channels (Quad to 4.0) and 6 channels (6.1(back) to 6.1)

  • Add audio channel (speaker layout) support

    • Implemented by using 20 bits from VideoInfo struct image_type flag

    • Follow layout definition from WAVEFORMATEXTENSIBLE

    • Add Script functions for audio layout support:

      • bool IsChannelMaskKnown(clip)

      • int GetChannelMask(clip)

      • SetChannelMask(clip, bool known, int dwChannelMask)

      • SetChannelMask(clip, string ChannelDescriptor)

    • Add friendly names for the 18 speaker positions (e.g. "FL" for front left)

    • Add friendly names for their frequently used combinations (e.g. "stereo" for "FL+FR") to be used in SetChannelMask.

    • GetChannel, GetChannels, MergeChannels: set default channel layout if channel count is 1 to 8

    • ConvertToMono, GetLeftChannel, GetRightChannel: sets channel layout to "mono"

    • AudioDub will inherit channel layout setting from the audio clip.

    • KillAudio calls SetChannelMask(false, 0)

    • "Info": displays channel mask info in the audio section when exists

    • #358: add "bold" parameter to "SubTitle" and "Info"

    • Add "bold", "italic", "noaa" parameters for SubTitle, Info, ShopSMTPE, ShowTime, ShowFrameNumbers, ShowCRC32

Build environment, Interface

  • Feature (#317): (v10) The color format of a VideoFrame can now be retrieved with its GetPixelType() (CPP) and avs_video_frame_get_pixel_type (C) function. Before, there was no reliable way of knowing it on a frame from propGetFrame(). The internally stored pixel_type in VideoFrame is properly converted upon a Subframe (Y8-32), SubframePlanar (strip alpha).

  • Feature (#317): (v10) added VideoFrame::AmendPixelType and avs_video_frame_amend_pixel_type. Introduced in order to keep VideoInfo and VideoFrame pixel_type synchronized for special cases: when filter constructor would just change VideoInfo::pixel_type, but the frame would be passed w/o any change, like in ConvertFromDoubleWidth or CombinePlanes.

  • Feature (#314): Added AVSValue::GetType() (v10) Returns an AvsValueType enum directly, one can use it instead of calling all IsXXX functions to establish the type. (Rust use case)

  • Fix in headers (#314): Changed NewVideoFrameP() and avs_new_video_frame_p() property source argument to const

  • Enhancement in headers (#314): Made VideoFrameBuffer destructor public like in other classes of the public API to prevent compiler errors downstream when calling non-const member functions

  • Address Issue #305: Support for non-decorated avisynth_c_plugin_init in C-plugins

  • Fix: C API undefined behavior when upstream throw runtime error

  • CMakeLists.txt: fix clang-cl/intel with ninja generator

  • Fix: C interface crash when using avs_new_video_frame_p(_a)

  • Fix: C interface avs_prop_get_data behave like C++ counterpart. Interface version is dor this fix is 9.2

  • CMakeLists.txt: add support for Intel C++ Compiler 2022

  • CMakeLists.txt: add support for Intel C++ Compiler 2023

  • Bump Interface version. Interface version is 10.0 AVISYNTH_INTERFACE_VERSION = 10, AVISYNTHPLUS_INTERFACE_BUGFIX_VERSION = 0

  • Address #282: make 32-bit MSVC build to generate both decorated and undecorated export function names for C plugins

  • (v10) Add audio channel support to C++ interface by using 18+2 VideoInfo.image_type bits

    • Check for existence: bool VideoInfo::IsChannelMaskKnown()

    • Setting: void VideoInfo::SetChannelMask(bool isChannelMaskKnown, unsigned int dwChannelMask)

    • Retrieving: unsigned int VideoInfo::GetChannelMask()

    • enums AvsChannelMask and AvsImageTypeFlags

  • (v10) Add audio channel support to C interface

    • Check for existence: bool avs_is_channel_mask_known(const AVS_VideoInfo * p);

    • Setting: void avs_set_channel_mask(const AVS_VideoInfo * p, bool isChannelMaskKnown, unsigned int dwChannelMask);

    • Retrieving: unsigned int avs_get_channel_mask(const AVS_VideoInfo * p);

    • supporting enums

Bugfixes

  • Fix: "Text" filter negative x or y coordinates (e.g. 0 instead of -1)

  • Fix: "Text" filter would omit last character when x<0

  • Fix: "Text" halo_color needs only MSB=$FF and not the exact $FF000000 constant for background fade

  • Fix: (#304) "ColorYUV" analyze=true was displaying wrong min-max values for YUY2

  • Fix: (#293) "Text" to throw proper error message if the specified font name (e.g. Arial) is not found among internal bitmap fonts.

  • Fix: (#293) "Subtitle" and "Text" filter to respect the explicitely given coorditanes for y=-1 or x=-1, instead of applying vertical/horizontal center alignment.

  • Fix (#283): broken runtime functions Min/Max/MinMaxDifference when threshold is not 0 (returned -1). Regression in 3.7.2

  • Fix (#282): ConvertToRGB - do check for exact 8 or 16 bit input, because packed RGB formats exist only for 8 and 16 bits - keep alpha for RGBA planar - convert RGBAP8/16 to RGB32/64, while RGBP8/16 is still RGB24/48

  • Fix crash when outputting VfW (e.g. VirtualDub) for YUV422P16, or P10 in Intel SSE2 clang builds

  • Fix Clang build AviSource crash on yuv422p10le UTVideo at specific widths (SSE2 or SSE4.1)

  • Fix: (#340): stop memory leak on propSet / MakePropertyWritable

  • Fix: (#347): possible crash of LLVM builds (clang-cl, Intel NextGen) on pre-AVX (SSE4-only) CPUs.

  • Fix: (#348): bitrol/bitror script functions return incorrect results when argument is negative (regression since ported from Avisynth 2.6 to plus)

  • Fix: (#350): ConvertXXX to accept YV411 clip's frame property _ChromaLocation set to 'left','topleft' and 'bottomleft' instead of giving an error message.

  • Fix: (#360): plane filler wrongly assumed that pitch is rowsize, would crash when aligned Crop was immediately followed by a GreyScale.

Optimizations

  • Enhanced performance in ConvertBits Floyd dither (dither=1) for 10->8, 16->8 and 16->10

  • Added AVX2 code path for YV24 to RGB24/32 conversions (+50% fps)

Documentation

  • Internal plugins, syntax, ...: almost fully revised and made up-to-date. Big thanks to Reel-Deal!

  • Update build documentation with 2023 Intel C++ tools. See Compiling Avisynth+
