I fixed the EXIF that was not handled and I set the output buffers to 16 bit when reading 10/12 bit. We lose the bit depth information though. |

Build with default Ubuntu 22.04 libavif package fails with compilation error: Version info: |

I split the tests and fixed the compilation on Ubuntu (that API is also useless for us). I added a test for EXIF (that only works with libavif HEAD). |

@vrabaud Thanks a lot for the update. Looks like you forgot about opencv_extra patch: |

All imgcodecs tests now pass. |

All tests passed on my side with Ubuntu 22.04. Thanks a lot! I'll try to look into code in details for the next several days and provide feedback. I also added Ubuntu 22.04 config with libavif on board to CI in opencv/ci-gha-workflow#101 and opencv-infrastructure/opencv-gha-dockerfile#18 |

(the CI error seems unrelated: DNN with CUDA error) |

@vrabaud We discussed the solution on core team meeting and decided to disable libavif by default for now and treat it's support as experimental till 4.9.0. Could you disable the option by default? I'll add CI configuration a bit later after the release. |

Major issue is mostly engineering. AVIF has a lot of own dependencies that we do not want to bring into OpenCV. Licenses for AVIF dependence sub-tree is open issue too. |

Licenses are fine: libavif is BSD 2 clause. |
