Bug ID: 519841
Summary: Exiv2 error exception writing metadata even delegating
exiftool all operations to write metadata
Classification: Applications
Product: digikam
Version First 9.0.0
Reported In:
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: grave
Priority: NOR
Component: Metadata-Engine
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Created attachment 192078
--> https://bugs.kde.org/attachment.cgi?id=192078&action=edit
a file with this problem
I have a set of pictures where Digikam fails silently to write metadata
(caption or title for example) on the file : it set the metadata in the
database but not in the file.
Running with debug I can see Digikam try to use Exiv2 instead of exiftool (even
Check ExifTool availability: true) and exiv2 crashes with "Error # 38 :
"Taille du segment JPEG XMP est plus grand que 65535 octets". See debug log
below.
Digikam is configurated to delegate exiftool all operations to write metadata
but it seems it does not do that.
> exiftool on these files is ok, no error
