| |
| The changes are relative to the previous release, unless the baseline is specified. |
| |
| ## [Unreleased] |
| |
| ### Added since 1.0.0 |
| * 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`. |
| Utility functions for working with gain maps are also added. |
| 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 a --qgain-map flag to control the gain map quality in avifenc. |
| * Add the headerFormat member of new type avifHeaderFormat to avifEncoder. |
| * Add experimental API for reading and writing "mif3"-branded AVIF files |
| behind the compilation flag AVIF_ENABLE_EXPERIMENTAL_MINI. |
| * 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. |
| * Add imageSequenceTrackPresent flag to the avifDecoder struct. |
| * avifImageScale() function was made part of the public ABI. |
| * Add avif_cxx.h as a C++ header with basic functionality. |
| * Add enum aliases AVIF_COLOR_PRIMARIES_SRGB, AVIF_COLOR_PRIMARIES_BT2100, |
| AVIF_COLOR_PRIMARIES_DCI_P3, AVIF_TRANSFER_CHARACTERISTICS_PQ. |
| * Add avifResult enum entry AVIF_RESULT_INTERNAL_ERROR. |
| * Require libyuv by default (but it can still be disabled with |
| -DAVIF_LIBYUV=OFF). |
| * Add avifdec --icc flag to override the output color profile. |
| * Add experimental API for reading and writing 16-bit AVIF files behind the |
| compilation flag AVIF_ENABLE_EXPERIMENTAL_SAMPLE_TRANSFORM. |
| * Add AVIF_CHROMA_SAMPLE_POSITION_RESERVED to avifChromaSamplePosition enum. |

| * Fix memory errors reported in crbug.com/1501766, crbug.com/1501770, and |
| crbug.com/1504792 by [Fudan University](https://secsys.fudan.edu.cn/). |

| that can only take the values: OFF, LOCAL or SYSTEM. |
| * For the gtest, jpeg, libsharpyuv, libxml2, libyuv and zlibpng dependencies, |
| AVIF_LOCAL_* is now replaced by flags AVIF_* that can take the values: |
| OFF, LOCAL or SYSTEM. |
| * src/reformat.c: Allocate the threadData array directly. |

| * Fix wrong alpha plane deallocation when decoded tile pixel format does not |
| match reconstructed output image pixel format (b/320234262). |
| * Fix identical chunk skipping optimization when writing animation data |
| (b/321189607). |
| * Fix ID selection for artificial grid alpha item when decoding a grid of tiles |
| which each have an associated auxiliary alpha image item |
| (https://crbug.com/oss-fuzz/65657). |
| * ext/libjpeg.cmd now pulls libjpeg-turbo instead of libjpeg and AVIF_JPEG=LOCAL |
| now expects the library dependency in ext/libjpeg-turbo/build.libavif. |
| * Fix 'iloc' box parsing bugs that may have wrongly accepted, rejected or parsed |
| some files with rare values of offset_size, length_size, base_offset_size and |
| index_size. |
| * 'infe' boxes with an item_type different from 'mime' and without a |
| null-terminated item_name are now considered invalid as per ISO/IEC 14496-12. |

| |
| ## [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 |

| |
| ## [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 |

| * 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 |

| * 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. |

| * 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 |

| uint16_t |
| * Allow clamped grid cells in avifEncoderAddImageGrid() |
| |

| - Populate nclx box inside of OBU in addition to AVIF container |
| |
| ## [0.4.1] - 2019-10-17 |
| ### Added |

| - aviffuzz prints keyframe information as it repeatedly decodes |
| |
| ### Changed |

| - dav1d codec's open function no longer does an initial unnecessary feed |
| - avifCodecDecodeInput now stores an array of avifSample which know if they're keyframes |
| - moved codec flushing code into avifDecoderFlush() so it is available to avifDecoderNthImage |
| - ptsInTimescales is now calculated independently of frame decode order |
| |
| ## [0.3.9] - 2019-09-25 |
| ### Changed |
| - Split avifRawData and avifStream into read-only (const) and read/write versions, updated code accordingly |

| |
| ## [0.3.3] - 2019-07-24 |
| ### Added |
| - new helper function `avifPeekCompatibleFileType()` |
| - expose ioStats on avifDecoder again (currently only interesting when reading items) |
| |
| ### Changed |
| - Fixed some warnings (removed unused variables and a bad cast) |
| - Add a define in dav1d layer for supporting older dav1d codecs |
| - Enabled tons of warnings, and warnings-as-errors; Fixed associated fallout |
| - codec_dav1d: disambiguate "needs more data" and "no more frames" in feed data pump |
| |
| ## [0.3.2] - 2019-07-23 |

| - 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 |

| - 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 |

| - 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 |
| |

| ### 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) |
