# Changelog
All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

## [1.0.1] - 2023-08-29

### Changed
* gdk-pixbuf: Explicitly pass link directories
* gdk-pixbuf: Fix build failure after imir.mode -> imir.axis rename

## [1.0.0] - 2023-08-24

With the 1.0.0 release, the ABI will be more stable from now on. Please note
the allocation and initialization requirements for avifImage, avifDecoder,
avifEncoder, and avifRGBImage in the "avif/avif.h" header.

List of incompatible ABI changes in this release:

* The clli member was added to the avifImage struct.
* The repetitionCount member was added to the avifEncoder and avifDecoder
  structs.
* The quality and qualityAlpha members were added to the avifEncoder struct.
* Check that functions returning pointers do not return NULL before accessing
  those pointers.
* Check the return value of avifEncoderSetCodecSpecificOption().
* The maxThreads member was added to the avifRGBImage struct.
* Check the return value of avifRGBImageAllocatePixels(), avifRWDataRealloc(),
  avifRWDataSet(), avifImageSetProfileICC(), avifImageSetMetadataExif() and
  avifImageSetMetadataXMP().
* The meaning of the keyframeInterval member of avifEncoder struct has changed
  slightly. When set to a value of "n",
    * Before: It forces a keyframe on every nth frame.
    * After: Any set of "n" consecutive frame will have at least one keyframe
      (every nth frame may or may not be a keyframe).

### Added
* Add STATIC library target avif_internal to allow tests to access functions
  from internal.h when BUILD_SHARED_LIBS is ON.
* Add clli metadata read and write support
* Add repetitionCount member to avifEncoder and avifDecoder structs to specify
  the number of repetitions for animated image sequences.
* Add quality and qualityAlpha to avifEncoder. Note: minQuantizer,
  maxQuantizer, minQuantizerAlpha, and maxQuantizerAlpha are deprecated. Code
  should be updated to set quality (and qualityAlpha if applicable) and leave
  minQuantizer, maxQuantizer, minQuantizerAlpha, and maxQuantizerAlpha
  initialized to the default values.
* The --target-size flag in avifenc was added to adapt the quality so that the
  output file size is as close to the given number of bytes as possible.
* Add the public API function avifImageIsOpaque() in avif.h.
* Add the public API functions avifImagePlane(), avifImagePlaneRowBytes(),
  avifImagePlaneWidth(), and avifImagePlaneHeight() in avif.h.
* Add experimental API for progressive AVIF encoding.
* Add API for multi-threaded YUV to RGB color conversion.
* Add experimental support for AV2 behind the compilation flag AVIF_CODEC_AVM.
  AVIF_CODEC_CHOICE_AVM is now part of avifCodecChoice.
* Add experimental YCgCo-R support behind the compilation flag
  AVIF_ENABLE_EXPERIMENTAL_YCGCO_R.
* Allow lossless 4:0:0 on grayscale input.
* Add avifenc --no-overwrite flag to avoid overwriting output file.
* Add avifenc --clli flag to set clli.
* Add support for all transfer functions when using libsharpyuv.

### Changed
* Enable the libaom AV1E_SET_SKIP_POSTPROC_FILTERING codec control by default.
* Use the constant rate factor (CRF) instead of the constant quantization
  parameter (CQP) rate control mode with the SVT-AV1 encoder.
* Exif and XMP metadata is exported to PNG and JPEG files by default,
  except XMP payloads larger than 65502 bytes in JPEG.
* The --grid flag in avifenc can be used for images that are not evenly divided
  into cells.
* Apps must be built with libpng version 1.6.32 or above.
* Change the encoder to write the boxes within the "stbl" box in the order of
  stsd, stts, stsc, stsz, stco, stss.
* avifImageCopy() no longer accepts source U and V channels to be NULL for
  non-4:0:0 input if Y is not NULL and if AVIF_PLANES_YUV is specified.
* The default values of the maxQuantizer and maxQuantizerAlpha members of
  avifEncoder changed from AVIF_QUANTIZER_LOSSLESS (0) to
  AVIF_QUANTIZER_WORST_QUALITY (63). The behavior changed if minQuantizer and
  maxQuantizer are left initialized to the default values. Code should be
  updated to set the quality member. Similarly for the alpha quantizers and
  qualityAlpha.
* avifImageRGBToYUV() and avifImageYUVToRGB() handle avifImage bit depths 8, 10,
  12 and now also 16. Files read by apps/shared/ can output 16-bit avifImage
  instances.
* Update aom.cmd: v3.6.1
* Update dav1d.cmd: 1.2.1
* Update libsharpyuv: 0.4.0
* Update rav1e.cmd: v0.6.6
* Update svt.cmd/svt.sh: v1.6.0
* Update zlibpng.cmd: zlib 1.2.13 and libpng 1.6.39
* avifImageCreate(), avifImageCreateEmpty(), avifEncoderCreate() and other
  internal functions now return NULL if a memory allocation failed.
* avifEncoderSetCodecSpecificOption() now returns avifResult instead of void to
  report memory allocation failures.
* At decoding, avifIOStats now returns the same values as at encoding.
* avifRGBImageAllocatePixels(), avifRWDataRealloc(), avifRWDataSet(),
  avifImageSetProfileICC(), avifImageSetMetadataExif() and
  avifImageSetMetadataXMP() now return avifResult instead of void to report
  memory allocation failures.
* avifReadImage(), avifJPEGRead() and avifPNGRead() now remove the trailing zero
  byte from read XMP chunks, if any. See avifImageFixXMP().
* Force keyframe for alpha if color is a keyframe.
* Write primaries and transfer characteritics info in decoded PNG.
* Add support for reading PNG gAMA, cHRM and sRGB chunks.
* The 'mode' member of the avifImageMirror struct was renamed 'axis'.
* Change the type of the 'depth' parameter from int to uint32_t in
  avifFullToLimitedY(), avifFullToLimitedUV(), avifLimitedToFullY(), and
  avifLimitedToFullUV().

## [0.11.1] - 2022-10-19

* avifmetadatatest: don't include avif/internal.h
* avifrgbtoyuvtest: skip if no libsharpyuv
* Disable tests that may fail if the codec is not aom (#1176)

## [0.11.0] - 2022-10-12

There are incompatible ABI changes in this release. The alphaRange member was
removed from the avifImage struct. The chromaDownsampling and avoidLibYUV
members were added to the avifRGBImage struct. The imageDimensionLimit member
was added to the avifDecoder struct. avifImageCopy() and
avifImageAllocatePlanes() signatures changed. It is necessary to recompile your
code. Also check the return values of avifImageCopy() and

  reduces artifacts caused by 420 chroma downsampling. Needs libsharpyuv (part
  of the libwebp repository) at compile time.
* avifenc: Add --ignore-exif and --ignore-xmp flags.
* avifenc: Add --autotiling, which sets --tilerowslog2 and --tilecolslog2

* avifImageRGBToYUV() now uses libyuv fast paths by default. It may slightly
  change conversion results. The old behavior can be restored by setting
  avifRGBImage::chromaDownsampling to AVIF_CHROMA_DOWNSAMPLING_BEST_QUALITY
  and avifRGBImage::avoidLibYUV to AVIF_TRUE.
* avifRGBImage::chromaUpsampling now only applies to conversions that need
  upsampling chroma from 4:2:0 or 4:2:2 and has no impact on the use of libyuv.

## [0.8.0] - 2020-07-14

### Added
* Monochrome (YUV400) support **
  * All encoding/decoding and internal memory savings are done/functional
  * libaom has a bug in chroma_check() which crashes when encoding monochrome, to be fixed in a future (>v2.0.0) version
  * rav1e didn't implement CS400 until rav1e v0.4.0
  * libavif safely falls back to YUV420 when these earlier codec versions are detected
    * NOTE: If you want to do heavy monochrome testing, wait for newer versions to libaom/rav1e!
* Image sequence encoding support
  * Required medium-sized refactors in the codec layers
  * Image sequences (tracks) now fully support all metadata properly (Exif/XMP/transforms)
  * avifenc can now encode a series of same-sized images with a consistent framerate, or each with their own custom duration
* Bilinear upsampling support
* avifenc: Add --ignore-icc, which avoids embedding the ICC profile found in the source image
* avifdec: Add --info, which attempts to decode all frames and display their basic info (merge of avifdump)
* avifenc: add --tilerowslog2 and --tilecolslog2 (wantehchang)
* Added `contrib` dir for any unofficially supported code contributions (e.g. gdk-pixbuf)

### Changed
* CICP Refactor (breaking change!)
  * Remove most references to "NCLX", as it is mostly an implementation detail, and the values are really from MPEG-CICP
  * Eliminate avifProfileFormat: having an ICC profile is not mutually exclusive with signaling CICP
  * CICP is now always available in an avifImage, set to unspecified by default
  * Added --cicp as an alias for --nclx (semi-deprecated)
  * Setting CICP via avifenc no longer overrides ICC profiles, they co-exist
  * Simplified avifenc argument parsing / warnings logic
  * avifenc/avifdec/avifdump now all display CICP when dumping AVIF information
  * nclx colr box contents are guaranteed to override AV1 bitstream CICP (as MIAF standard specifies)
  * Added comments explaining various decisions and citing standards
  * Removed ICC inspection code regarding chroma-derived mtxCoeffs; this was overdesigned. Now just honor the assoc. colorPrimaries enum
  * Reworked all examples in the README to reflect the new state of things, and clean out some cruft
  * Harvest CICP from AV1 bitstream as a fallback in avifDecoderParse() if nclx box is absent
* All data other than actual pixel data should be available and valid after a call to avifDecoderParse()
* Refactor avifDecoder internal structures to properly handle meta boxes in trak boxes (see avifMeta)
* Update libaom.cmd to point at the v2.0.0 tag
* Update dav1d.cmd to point at the 0.7.1 tag
* Re-enable cpu-used=7+ in codec_aom when libaom major version > 1
* Memory allocation failures now cause libavif to abort the process (rather than undefined behavior)
* Fix to maintain alpha range when decoding an image grid with alpha
* Improvements to avifyuv to show drift when yuv and rgb depths differ
* Remove any references to (incorrect) "av01" brand (wantehchang)
* Set up libaom to use reduced_still_picture_header (wantehchang)
* Use libaom cpu_used 6 in "good quality" usage mode (wantehchang)
* Update avifBitsReadUleb128 with latest dav1d code (wantehchang)
* Set encoder chroma sample position (wantehchang)
