libavif-1.2.0

[Bruce Dubbs]

New minor version.

[Douglas R. Reno]

1.2.0 - 2025-02-25
Added since 1.1.1

    Turn on the gain map API. Remove the AVIF_ENABLE_EXPERIMENTAL_GAIN_MAP CMake
    flag.
    Allow YCgCo_Re and YCgCo_Ro encoding/decoding and update the enum values to
    the latest CICP specification. Remove the AVIF_ENABLE_EXPERIMENTAL_YCGCO_R
    CMake flag.
    Add the properties and numProperties fields to avifImage. They are filled by
    the avifDecoder instance with the properties unrecognized by libavif. They are
    written by the avifEncoder.
    Add avif(Un)SignedFraction structs and avifDoubleTo(Un)SignedFraction
    utility functions.
    Add 'avifgainmaputil' command line tool to installed apps.
    Add avifCropRectRequiresUpsampling().
    Add experimental support for PixelInformationProperty syntax from HEIF 3rd Ed.
    Amd2 behind the compilation flag AVIF_ENABLE_EXPERIMENTAL_EXTENDED_PIXI.
    Add experimental Sample Transform recipe
    BIT_DEPTH_EXTENSION_12B_8B_OVERLAP_4B.

Changed since 1.1.1

    avifenc: Allow large images to be encoded.
    Fix empty CMAKE_CXX_FLAGS_RELEASE if -DAVIF_CODEC_AOM=LOCAL -DAVIF_LIBYUV=OFF
    is specified. #2365.
    Rename AVIF_ENABLE_EXPERIMENTAL_METAV1 to AVIF_ENABLE_EXPERIMENTAL_MINI and
    update the experimental reduced header feature to the latest specification
    draft. Rename AVIF_HEADER_REDUCED to AVIF_HEADER_MINI.
    Update the experimental Sample Transform feature behind the
    AVIF_ENABLE_EXPERIMENTAL_SAMPLE_TRANSFORM CMake flag to the latest
    specification draft.
    Ignore gain maps with unsupported metadata. Handle gain maps with
    writer_version > 0 correctly.
    Simplify gain map API: remove the enableParsingGainMapMetadata setting, now
    gain map metadata is always parsed if present and if this feature is compiled
    in. Replace enableDecodingGainMap and ignoreColorAndAlpha with a bit field to
    choose image content to decode. Remove gainMapPresent: users can check if
    decoder->image->gainMap != NULL instead. Remove avifGainMapMetadata and
    avifGainMapMetadataDouble structs.
    Write an empty HandlerBox name field instead of "libavif" (saves 7 bytes).
    Check for FileTypeBox precedence in avifParse().
    Do not write an alternative group with the same ID as an item.
    Update aom.cmd/LocalAom.cmake: v3.12.0. The new codec-specific option tune=iq
    (image quality) is added in libaom v3.12.0.
    Update parseAV2SequenceHeader() and avm.cmd: research-v9.0.0
    Update dav1d.cmd/dav1d_android.sh/LocalDav1d.cmake: 1.5.1
    Update libjpeg.cmd/LocalJpeg.cmake: v3.0.4
    Update libxml2.cmd/LocalLibXml2.cmake: v2.13.5
    Update libyuv.cmd: ccdf87034 (1903)
    Update svt.cmd/svt.sh/LocalSvt.cmake to v3.0.0. When available, use
    EbSvtAv1EncConfiguration::lossless and ::level_of_parallelism in libavif.
    Remove AVIF_ENABLE_GTEST CMake option. It's now implied by
    AVIF_GTEST=LOCAL/SYSTEM.
    Deprecate avifEncoder's minQuantizer, maxQuantizer, minQuantizerAlpha,
    and maxQuantizerAlpha fields. quality and qualityAlpha should be used
    instead. Deprecate avifenc's --min, --max, --minalpha and --maxalpha
    flags. -q or --qcolor and --qalpha should be used instead.
    For dependencies, the deprecated way of setting AVIF_LOCAL_* to ON is
    removed. Dependency options can now only be set to OFF/LOCAL/SYSTEM.
    Change the default quality for alpha to be the same as the quality for color.
    Allow decoding subsampled images with odd Clean Aperture dimensions or offsets.
    Deprecate avifCropRectConvertCleanApertureBox() and
    avifCleanApertureBoxConvertCropRect(). Replace them with
    avifCropRectFromCleanApertureBox() and avifCleanApertureBoxFromCropRect().
    Write descriptive properties before transformative properties.
    Reject non-essential transformative properties.
    Treat avifenc --stdin as a regular positional file path argument.
    Update man pages based on avifenc/dec's --help message.
    android_jni: Support 16kb page size
    android_jni: Set threads to 2 instead of CPU count
    Fix overflows when dealing with alpha during YUV/RGB conversions and in
    avifRGBImageAllocatePixels().
    Make avifEncoder.headerFormat a flag combination for future features.
    Rename AVIF_HEADER_FULL to AVIF_HEADER_DEFAULT. Deprecate AVIF_HEADER_FULL.
    Fix decoding image sequences with non video tracks (such as audio or subtitles).
    Fix type checking of auxiliary tracks: previously any auxiliary track was
    assumed to be alpha, even if it was a different type. If the aux type is absent,
    it is assumed to be alpha.
