It's not alignment, because the failing access to 0x7fcef09ad000 is well aligned. What I found out is that this address computes like this: start of reference frame: 0x7fcef092d800 width of...
That's probably related to the ICC profile used. Since you encode with `heif-enc`, the ICC profile from the original JPEG is also used for the output. It might be that...
I am not aware of any way to store IPTC natively in HEIF images. The preferred way to do this seems to be to convert the data to XMP and...
BTW: the image `BoxeThai-600x400.jpg` does not seem to contain any metadata...
Yes, thanks. The new link contains the metadata.

We could indeed add an API to store and read custom boxes. It's not that easy because of handling the cross-references between boxes (e.g. indicating to which image some metadata...
There is no practical limit on the HEIF box size (64bit length). I know that JPEG APP chunks are
I did some more searching about IPTC (IIM) vs. XMP, and it seems that XMP superseeded the IIM stream format (e.g. see here https://en.wikipedia.org/wiki/IPTC_Information_Interchange_Model). It appears that for other formats,...
Please have a look into the 'iptc' branch, I added. There is a new API function 'add_generic_metadata()' which you could use to attach IPTC streams as another chunk for metadata....
