• update to 1.23.0:

• add API functions to read and write metadata: ambient viewing environment nominal diffuse white luminance

• update to 1.22.2:

• adds a output_image_nclx_profile_passthrough option to heif_decoding_options
• build issues with OpenJPEG plugin (#1813)
• non-plain C in header (#1812)

• update to 1.22.0:

• This is a large release with substantial new functionality, mainly focusing on generalized image formats (e.g., multi- spectral images) and a reworked implementation of ISO/IEC 23001-17 (lossless image codec).
• HDR up to 64 bpp
• Multi-component images with arbitrary component layouts (multi-spectral images, arbitrary non-visual data)
• Filter-array (Bayer / mosaic) images, with debayering in color transformation pipeline
• Metadata: chroma-sample location (cloc), sample non- uniformity (snuc), sensor bad-pixel map (sbpm), polarization pattern (splz)
• heif-dec can now convert to WebP (thanks to @torusrxxx).
• heif-enc can now accept input from WebP, HEIF, pure raw files (including floating point pixel data), and CMYK JPEG (converted to RGB).
• TIFF input can now read many TIFF formats used in geospatial imaging, like: 16-bit, signed integers, float samples, tiled TIFFs, GeoTIFF overview images, CMYK JPEG, YCbCr-as-JPEG. TIFFs with image tiling and multi-resolution layers are now reproduced as HEIFs when converted.
• PNG decoder/encoder: cICP, cLLI, and mDCV chunk support (#1697).
• heif-dec: auto-correct option to fix known input errors (e.g. mismatched NCLX/VUI).
• Image, Track, Sequence samples, image component GIMI content IDs
• Embedding of Turtle (.ttl) metadata files; automatic parsing of GIMI content IDs from Turtle
• AOM encoder plugin now auto-selects IQ tune mode
• mini-box syntax updated to the current HEIF version 4 draft (thanks @bradh for the initial implementation)
• unif brand (globally-unique-ID) support
• OMAF (omnidirectional images): indicate ISO/IEC 23000-22 spherical/omnidirectional image projection
• alpha bit-depth tracked through the color-conversion pipeline

• Build / CI

• requires C++20
• oss-fuzz integration overhauled
• fuzzers for tile API, generic API surface, and per-codec encoders

• update to 1.21.2:

• build script for JS/WASM now supports building with JPEG2000 and "ISO23001-17 Uncompressed" support.
• image sequence SAI data now works when using the OpenH264 decoder plugin

• update to 1.21.1:

• This patch release only fixes a build error with some GCC versions because of a missing #include.

• update to 1.21.0:

• This release adds full support for reading and writing HEIF image sequences. libheif will now encode HEIF image sequences with all included codecs.
• Since HEIF image sequences are very similar to MP4 videos, this new version is also capable of decoding most MP4 videos (without audio, of course).
• heif-enc documentation for sequence encoding
• API documentation for reading and writing sequences
• Support for image sequences with alpha channels. For most codecs, the alpha channel will be stored in a separate, auxiliary, monochrome track. For ISO/IEC 23001-17 (uncompressed) streams, the alpha channel is stored in the main video track.
• Support for sequence track edit lists to define the number of sequence repetitions (without actually repeating the video data).
• New encoder plugin using x264 to write H.264-compressed video streams and images.
• The FFmpeg decoder plugin will now decode both H.265 and H.264.
• Support for HEIF text items and language properties.

• version 1.20 requires at least ffmpeg 4, so go with version 7+
• update to 1.20.2:
• When opening tiled images, do not check against maximum image size immediately to allow for tile-based decoding of very large images.
• Several smaller fixes in writing image sequences
• CMake option to disable building of heif-view, which pulls in dependency on SDL
• Fixes reading/writing of GIMI content IDs
• Some build fixes
• Remove conditionals for openh264, we can build against noopenh264
• update to 1.20.1:
• Fixes a bug in decoder plugin loading.
• Changes from 1.20.0:
• Sequences:
• API for reading and writing image sequences. You can read and write sequences for all codecs (not just H.265 / AV1, but also JPEG-2000, ISO-23001-17 uncompressed, ...). Currently only intra-coded sequences are supported.
• API for reading and writing metadata sequences. The metadata tracks can contain any raw timed data.
• Support for SAI (sample auxiliary information). Timed samples (from image sequences or metadata) can have auxiliary data attached. Currently we support TAI timestamps and GIMI content description IDs.
• Support for track references.
• The API for sequences is described here: https://github.com/strukturag/libheif/wiki/Reading-and-Writing-Sequences
• New command line tool heif-view to show HEIF sequences (requires libSDL).
• Other new features:
• You can specify a security limit for the maximum total memory libheif may use for decoding. This is easier to handle than specifying limits on the maximum image size or single memory allocations.
• Support for TAI timestamps (in images and sequences) has been promoted from experimental to stable.
• FFMPEG plugin now supports HDR decoding
• Header files are now split into individual headers by topic. However, it should still be backwards compatible with heif.h being a catch-all covering the old content. For new functionality (sequences, TAI), you will need to include the specific headers.
• All struct names of the API are now also typedefs.
• add build requires for brotli which it looks for since 1.18
• prepare building heif-view
• update to 1.19.8:

• Set essential flag for transformative properties as required by MIAF. This fixes the display of AVIF images with transformations encoded by libheif in Chrome, which checks whether this flag is set. This mainly affected images encoded by ImageMagick.
• If the environment variable LIBHEIF_SECURITY_LIMITS is set to OFF, libheif will not check any security limits. This can be used if a user works with large images and the application software does not allow to adjust the libheif security limits.
• Resolved processing 16-bit JPEG-2000
