[1] https://github.com/AOMediaCodec/libavif.git

Here is the change log:

1.3.0 - 2025-05-09

Added since 1.2.1

* Add grayscale conversions in avifImageRGBToYUV and avifImageYUVToRGB.
* Add avifRGBFormatIsGray to check whether an avifRGBFormat is gray.

Changed since 1.2.1

* Reject the conversion in avifenc from non-monochrome/monochrome to
monochrome/non-monochrome when an ICC profile is present and not explicitly
discarded.
* Forbid encoding with AVIF_MATRIX_COEFFICIENTS_IDENTITY and
AVIF_PIXEL_FORMAT_YUV400 to be AV1 spec compatible.
* Do not go through RGB when reading/writing a grayscale PNG/JPG images in
avifenc/avifdec
* Ignore tmap items not present in `grpl` box
* Assume any id is present in only one altr group as per spec.
* avifpng.c: support ImageMagick app1 exif text data
* avifjpeg.c: check for uint32_t overflow before add
* Update googletest.cmd/LocalGTest.cmake: v1.16.0
* Update libjpeg.cmd/LocalJpeg.cmake: 3.1.0
* Update libsharpyuv: v1.5.0
* Update libxml2.cmd/LocalLibXml2.cmake: v2.14.0
* Update libyuv.cmd/LocalLibyuv.cmake: 4db2af62d (1909)
* Update LocalRav1e.cmake: cargo-c v0.10.12
* Update zlibpng.cmd: libpng 1.6.47
* Fix wrong Exif orientation set in JPEG or PNG output by avifdec when the input
AVIF file has an ImageRotation property with angle set to 1 or 3, has no
ImageMirror property, and carries an Exif chunk. Note that Exif orientation is
usually ignored in PNG files, so this mainly impacts JPEG files.
* Encoder: fix ispe property for tmap with grid.
* Decoder: check the ispe property of tmap items.
* Allow lowercase GUIDs in XMP when reading JPEG files.
* Update aom.cmd/LocalAom.cmake: v3.12.1
* Change avifenc to start in automatic tiling mode.
* Always forward Unspecified (2) CICP color primaries, transfer characteristics,
and matrix coefficients to the AV1 encoder. Rely on the 'colr' box instead.
* Declare *RowBytes as size_t in avifImageRGBToYUV()
* Check ftell returned value in avifjpeg.c
* Add integer overflow checks to makeRoom.
* LocalJpeg.cmake: Support multi-config generators.
