| # 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] | |
| ### Added | |
| * Add experimental API for reading and writing gain maps in AVIF files. | |
| If enabled at compile time, add `gainMap` field to `avifImage`, | |
| add `qualityGainMap` field to `avifEncoder`, add `gainMapPresent`, | |
| `enableDecodingGainMap`, `enableParsingGainMapMetadata` and | |
| `ignoreColorAndAlpha` to `avifDecoder`. | |
| Gain maps allow readers that support them to display HDR images that look | |
| good on both HDR and SDR displays. | |
| This feature is highly experimental. The API might change or be removed | |
| in the future. Files created now might not decode in a future version. | |
| This feature is off by default and must be enabled with the | |
| AVIF_ENABLE_EXPERIMENTAL_GAIN_MAP compilation flag. | |
| * Add experimental support for converting jpeg files with gain maps to AVIF | |
| files with gain maps. Requires libxml2, and the AVIF_ENABLE_EXPERIMENTAL_GAIN_MAP | |
| compilation flag. | |
| * Add the headerFormat member of new type avifHeaderFormat to avifEncoder. | |
| * Add experimental API for reading and writing "avir"-branded AVIF files | |
| behind the compilation flag AVIF_ENABLE_EXPERIMENTAL_AVIR. | |
| * Implement avifImageScale() fallback when libyuv is not available. | |
| * Partial import of libyuv to third_party/libyuv (new LICENSE). | |
| * Add avifenc flag suffixes ":update" and ":u". Quality-relative, | |
| tiling-relative and codec-specific flags can now be positional, relative to | |
| input files. | |
| * Add experimental support for layered AVIF encoding in avifenc. | |
| Use the --layered flag to enable layered AVIF encoding. | |
| Layered AVIF has multiple layers, which works like frame of animated AVIF, | |
| and layers can be rendered in progressive manner on supported viewers | |
| (e.g. Chrome 94 or newer). | |
| Only aom supports layered AVIF encoding at the time of writing. | |
| Add --scaling-mode flag to set scaling mode of each layer. | |
| This part of AV1 encoder is not as thoroughly tested, so there are higher | |
| possibility encoder may crash when given certain configuration or input. | |
| ### Changed | |
| * Update aom.cmd: v3.7.0 | |
| * Update svt.cmd/svt.sh: v1.7.0 | |
| * Update zlibpng.cmd: zlib 1.3 and libpng 1.6.40 | |
| ## [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 | |
| ### Changed | |
| * avifincrtest_helpers: Cast 64-bit offset to size_t | |
| * avifmetadatatest: don't include avif/internal.h | |

| * 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 | |
| avifImageAllocatePlanes(). | |
| ### Added | |
| * Add man pages for avifenc and avifdec | |
| * Add the avifChannelIndex type alias for enum avifChannelIndex | |
| * Add avifChromaDownsampling enum | |
| * Add chromaDownsampling field to avifRGBImage struct | |
| * Add support for AVIF_RGB_FORMAT_RGB_565 | |
| * Add imageDimensionLimit field to avifDecoder struct | |
| * Add autoTiling field to avifEncoder struct | |
| * Add new avifResult codes AVIF_RESULT_CANNOT_CHANGE_SETTING and | |
| AVIF_RESULT_INCOMPATIBLE_IMAGE | |
| * Add new enum constants AVIF_PIXEL_FORMAT_COUNT and AVIF_RGB_FORMAT_COUNT | |
| * avifdec: Add --dimension-limit, which specifies the image dimension limit | |
| (width or height) that should be tolerated | |
| * avifenc: Add --sharpyuv, which enables "sharp" RGB to YUV420 conversion, which | |
| 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 | |
| automatically. | |
| * avifenc: Input Exif orientation is converted to irot/imir by default. | |
| ### Changed | |
| * Fix memory leaks of metadata on avifenc exit | |
| * Update the handling of 'lsel' and progressive decoding to AVIF spec v1.1.0 | |
| * Treat an absent lsel and layer_id == 0xFFFF equivalently for backward | |

| * Update libyuv.cmd: f9fda6e7 (version 1844) | |
| * avifImageCopy() and avifImageAllocatePlanes() now return avifResult instead of | |
| void to report invalid parameters or memory allocation failures. | |
| * 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. | |
| Set avifRGBImage::avoidLibYUV accordingly to control the use of libyuv. | |
| * avifenc: Set the YUV format to 4:0:0 for grayscale PNGs | |
| * Support updating encoder settings and codec-specific options during encoding | |

| * Fix https://github.com/AOMediaCodec/libavif/issues/1086 | |
| * Exif and XMP metadata is imported from PNG and JPEG files. | |
| * avifImageSetMetadataExif() parses the Exif metadata and converts any Exif | |
| orientation found into transformFlags, irot and imir values. | |
| * Write 'auxi' box for animated images with alpha channel | |
| * Write 'auxv' as handler_type for alpha channel track | |
| * Use PNG_COLOR_TYPE_GRAY for 8-bit grayscale output | |
| * Replace repeated subtraction by modulo in calcGCD (fix b/246649620) | |
| * Change avifImageCreate to take uint32_t instead of int parameters | |
| * When writing an image sequence, check if it's safe to cast width and height to | |
| uint16_t | |
| * Allow clamped grid cells in avifEncoderAddImageGrid() | |
| ### Removed | |

| * avifdec: Added `--no-strict` to disable all strict flags | |
| * avifdec: Added `-r` (`--raw-color`), which avoids multiplying against AVIF alpha channel before packing into non-alpha formats (JPEG) | |
| * avifenc: Recognize the Y4M format string "C420mpeg2" | |
| * avifenc: Add `--crop` convenient alternative arg to the difficult-to-use `--clap` arg | |
| * avifenc: New default for `--yuv`: `"auto"`, which will use a source JPEG's internal YUV format instead of YUV444, if detected | |
| * Uses: Prevent colorspace conversion when reading from JPEG if possible (tongyuantongyu) | |
| * avifenc/avifdec: Add helpful values/calculations when dumping clap box | |
| * Added avifDiagnostics, which allows for a detailed, freeform error string upon decode or encode error | |
| * Create helper avifCropRect struct and methods for helping to manipulate/populate/validate avifCleanApertureBox | |
| * Added ability to set codec-specific options for color or alpha only | |
| * Support for libaom's ALL_INTRA mode (if available) | |
| * Create avifDecoder.imageCountLimit as a sanity check against malformed files | |
| * SVT: Image sequence encoding support (tongyuantongyu) | |
| * Added rav1e to AppVeyor builds | |
| ### Changed | |
| * avifenc/avifdec: Link AOM_LIBRARIES and use CXX if vmaf is present (1480c1) | |
| * Ensure that an AVIF has a ftyp box, and based on ftyp, has other appropriate toplevel boxes present as well | |
| * Avoid linking against libyuv if it is too old / incompatible | |
| * Always require a primary item when decoding items | |
| * Add some strictness around ipma box parsing (version/flags tuples must be unique across ipma boxes in a file) | |
| * Fix alpha grids by properly writing alpha grid metadata payload | |
| * A HandlerBox (hdlr) of type 'pict' must be the first box within the MetaBox (meta) | |
| * Add some typedefs for various flag decls in avif.h to self-document which flags should be used in which function arguments | |
| * When encoding single-frame images using libaom, clean up the encoder immediately after encoding the frame to cut down on resources high watermarks | |
| * Fail on reformat Identity (MC=0) with subsampling (not using YUV444) | |
| * Warn if alpha is limited range (deprecated) | |
| * Validate the first_chunk fields in the stsc box | |
| * In libaom all intra mode, set cq-level for user | |

| - Added `ext/aom.cmd` to perform a local checkout of the aom codebase, as an alternative to a real submodule. This allows downstream projects to use libavif without recursive submodule issues. | |
| - AppVeyor and Travis scripts now explicitly clone libaom into ext/ as an alternative to a submodule. | |
| ### Changed | |
| - Remove `ext/aom` as a submodule. If libavif users want to build aom from ext/, they must enable `AVIF_BUILD_AOM` and supply their own local copy. | |
| - Move the handful of public domain gb_math functions used by colr.c and eliminate the dependence on the gb library | |
| - Detect when libaom or libdav1d is being included by a parent CMake project and allow it | |
| - Offer libavif's include dir alongside the library in CMake (target_include_directories) | |
| ## [0.3.1] - 2019-07-22 | |
| ### Changed | |
| - Moved dependency on libm to avif executables, instead of directly on the library | |
| - Minor changes to README examples | |
| ## [0.3.0] - 2019-07-22 | |
| ### Added | |
| - new CMake option `AVIF_CODEC_AOM` to enable/disable the usage of AOM's codec (default: on) | |
| - new CMake option `AVIF_CODEC_DAV1D` to enable/disable the usage of dav1d's codec (default: off) | |
| - `codec_dav1d.c`, which provides decoding via `libdav1d` | |
| - fuzz.sh which builds with afl-clang and runs afl-fuzz | |
| - aviffuzz tool, used in fuzzing script | |
| - fuzz inputs made with colorist | |
| - `.clang-format` file | |
| - `avifArray*()` functions for basic dynamic arrays when parsing | |
| - `moov` box parsing | |
| - now reads 'avis' brands | |
| - Split avifDecoderRead() into components for image sequences: | |
| - avifDecoderSetSource() | |
| - avifDecoderParse() | |
| - avifDecoderNextImage() | |
| - avifImageCopy() | |
| - avifDecoderReset() | |
| - Added decoder and image timings for image sequences | |
| ### Changed | |
| - Reorganized internal struct avifCodec to accommodate multiple codecs simultaneously (compile time; not exposed to API) | |
| - Fix some compiler warnings | |
| - Sanity check offsets and sizes in items table before using | |
| - Bail out of box header advertises an impossible size | |
| - Ran clang-format on all of src and include | |
| - Fix copypasta leading to a memory leak in RGB planes | |
| - Switched items and properties during parse to use dynamic arrays | |
| - Refactored codec API to not require each codec to maintain per-plane decoder instances | |
| - avifImage can now "not own" its planes and directly point at decoder planes to avoid copies | |
| - aviffuzz attempts to decode all images in source material twice (using avifDecoderReset()) | |
| - Switch decoder->quality to explicit [minQuantizer, maxQuantizer], update assoc. constants | |
| - Add examples to README | |
| ## [0.2.0] - 2019-06-12 | |
| ### Added | |
| - Added `avifEncoder` and `avifDecoder` to match `avifImage`'s pattern and allow for easier future parameterization | |
| ### Changed | |
| - Renamed project in cmake to `libavif` to match new official repo naming | |
| - Updated appveyor script to use `libavif` | |
| - Updated examples and apps to use new encoder/decoder pattern | |
| ## [0.1.4] - 2019-06-11 | |
| ### Added | |
| - `avifPixelFormatToString()` convenience function for debugging/printing | |
| - `avifenc` and `avifdec` "apps" which show basic bidirectional conversion to y4m | |
| ### Changed | |
| - Make calling `avifImageYUVToRGB()` upon reading an avif optional | |
| - Moved `ext/aom` submodule to use official remote | |
| - Update `ext/aom` submodule to commit [38711e7fe](https://aomedia.googlesource.com/aom/+/38711e7fe1eff68296b0324a9809804aec359fa5) | |
| ### Removed | |
| - Remove all calls to `convertXYZToXYY()` as they were all unnecessary | |
| ## [0.1.3] - 2019-04-23 | |
| ### Changed | |
| - `ftyp` - Change `major_brand` to `avif` | |
| - `ftyp` - Reorder `compatible_brands`, add `MA1A` or `MA1B` when appropriate | |
| - Write `meta` box before `mdat` box for streaming friendliness | |
| ## [0.1.2] - 2019-04-18 | |
| ### Added | |
| - `AVIF_NCLX_COLOUR_PRIMARIES_P3` (convenient mirrored value) | |
| - `avifNclxColourPrimariesFind()` - Finds a builtin avifNclxColourPrimaries and name by a set of primaries | |
| ### Changed | |
| - Fixed enum name copypasta for `AVIF_NCLX_COLOUR_PRIMARIES_EG432_1` | |
| - Fix UV limited ranges when doing full<->limited range conversion | |
| ## [0.1.1] - 2019-04-15 | |
| ### Added | |
| - Added `appveyor.yml` (exported from Appveyor) | |
| - Move `ext/aom` to a proper submodule | |
| - Update AOM to commit [3e3b9342a](https://aomedia.googlesource.com/aom/+/3e3b9342a20147ec6e4f89aa290e20277c1260ce) with minor CMake changes | |
| ### Changed | |
| - Added static library artifact zip to Windows x64 builds (Appveyor) | |
| - Updated README to explain libavif's goals and a little more build info | |
| - Fix clang warning in `avifVersion()` signature | |
| ## [0.1.0] - 2019-04-12 | |
| ### Added | |
| - First version. Plenty of bugfixes and features await! | |
| - `ext/aom` based off AOM commit [3563b12b](https://aomedia.googlesource.com/aom/+/3563b12b766639ba445eb0e62a225a4419594aef) with minor CMake changes | |
| - An interest and willingness to maintain this file. | |
| - Constants `AVIF_VERSION`, `AVIF_VERSION_MAJOR`, `AVIF_VERSION_MINOR`, `AVIF_VERSION_PATCH` | |
| - `avifVersion()` function | |
