Bug ID: 479780
Summary: Face tags not writing to XMP on photos taken with
Android "Ultra HDR" setting
Classification: Applications
Product: digikam
Version: 8.2.0
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: Metadata-Xmp
Assignee: digikam-bugs-n...@kde.org
Reporter: ymneoe...@mozmail.com

Screenshots of normal/working XMP tags and non-working/Ultra HDR tags
STEPS TO REPRODUCE
1. Take a photo with Android (14+) camera with "Ultra HDR" enabled (I used
Pixel 6a). The "Ultra HDR" setting is found in the camera advanced settings
(https://piunikaweb.com/2023/12/08/how-to-enable-or-disable-ultra-hdr-in-the-pixel-camera-app/)
2. Make sure Digikam is configured to write face tags metadata (under Settings
> Behavior)
2. Import the photo into Digikam and scan for faces (or manually add a face)
3. Specify a person's name to trigger Digikam to write metadata.
OBSERVED RESULT
No face metadata is found in the XMP section. Neither Microsoft Photo or
Metadata Working Groups Regions tags are present. The only thing it writes is
person's name as a "keyword" under IPTC
EXPECTED RESULT
Both Microsoft Photo and Metadata Working Groups Regions should be present.
SOFTWARE/OS VERSIONS
Windows: 10
ADDITIONAL INFORMATION
When inspecting XMP tags for "Ultra HDR" images, various "Container" tags are
present. These seem to be documented at
https://developer.android.com/media/platform/hdr-image-format#GContainer_details
I suspect somehow they're preventing Digikam from writing face data to XMP.
This issue is preventing other applications that rely on XMP from reading face
tags
