Make sure the suite is up-to-date before reporting an issue. It might've been fixed already.

Try running the build again at a later time.

what is jxl ?

JPEG XL is a royalty-free raster-graphics file format that supports both lossy and lossless compression. See https://jpeg.org/jpegxl/

something has broken or incompatible code ?

Projects change rapidly. So, broken code is expected. It may be possible to disable libjxl requirement in ffmpeg. The commit https://github.com/libjxl/libjxl/commit/b08a704978d5aeaf6fd1e2aee3ae5907a89e1f96 says

the signature of JxlDecoderGetColorAsEncodedProfile, JxlDecoderGetICCProfileSize, and JxlDecoderGetColorAsICCProfile changed: a deprecated unused argument was removed.

It may be possible to disable libjxl requirement in ffmpeg

Thanks, did that and ffmpeg built fine.

The response:

You'll need to update your code, the API has changed in b08a704

[hydra3333]

There has been some activity in ffmpeg recently, I wonder if this has been resolved - does anyone know ?

[Biswa96]

Please try to rebuild ffmpeg. A patch has been added here https://github.com/m-ab-s/media-autobuild_suite/commit/28f9bb3ce7b1de232f6ebfb10ac2ea0a6e732bdb

Has anyone submitted a patch to ffmpeg upstream?

[1480c1]

I have not yet, as I could not find any easy way to detect the new API changes. A simple patch is at https://github.com/m-ab-s/mabs-patches/blob/master/ffmpeg/0001-libjxldec-remove-deprecated-fields.patch, but as mentioned, it has no version bumps nor macro checks.

[GyanD]

Unfortunately, looks like the API changes weren't accompanied with a version bump.
