> Apple maker note tags written as LONG8 are dropped
> --------------------------------------------------
>
> Key: TIKA-4776
> URL: https://issues.apache.org/jira/browse/TIKA-4776
> Project: Tika
> Issue Type: Improvement
> Reporter: Dominik Schmidt
> Assignee: Tilman Hausherr
> Priority: Major
> Fix For: 4.0.0, 3.3.3
>
>
> Apple maker notes in HEIC/JPEG images store several tags as LONG8 (TIFF
> format code 16), e.g. the Live Photo video index (tag 0x0017). Example:
> for a Live Photo still taken with an iPhone 15 Pro on iOS 18.5, tag
> 0x0017 is written with format code 16 and value 5283876.
> The bundled metadata-extractor (2.20.0) only decodes the classic TIFF
> format codes 1-12 and drops such tags, so Tika never emits
> "img:Live Photo ID" even though metadata-extractor's
> AppleMakernoteDirectory defines the tag name. Only the content
> identifier ("img:Content Identifier", stored as a plain string) comes
> through today.
> This matters for pairing Apple Live Photos: the still image and the
> QuickTime video share a content identifier (the video side is covered
> by TIKA-2861), and the Live Photo video index is the image-side marker
> that reliably identifies a still as part of a Live Photo (whereas just
> "Content Identifier" seems to be a bit weak).
> This is fixed upstream in metadata-extractor:
> [https://github.com/drewnoakes/metadata-extractor/issues/738]
> [https://github.com/drewnoakes/metadata-extractor/pull/739]
> Verified end-to-end with a patched metadata-extractor build: Tika then
> emits both "img:Content Identifier" and "img:Live Photo ID" for a real
> Live Photo HEIC, with no Tika code change required.
> Once a metadata-extractor release containing the fix is available, the
> dependency (metadata.extractor.version in tika-parent) needs a bump.
> It would be great to add a regression test then.
