            Bug ID: 379833
           Summary: Sidecar files are not being created for some files
           Product: digikam
           Version: 5.5.0
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Metadata-Sidecar
          Assignee: digikam-devel at kde.org
          Reporter: aegoreev at gmail.com
  Target Milestone: ---

I just added many video files (mp4) to a folder in digiKam collection and
noticed that xmp sidecar was created for only one file.

If I for example add geolocation to the file that has xmp I get no GUI error
and GPS coordinates being added to the sidecar.
Here is the output of the terminal:

If I try to add geolocation to another file from this folder I get the error
"Failed to open file" after pressing "Save". No sidecar being created.

I did try creating an empty sidecar manually but I got the same error and no
information was written to it.

All files have same writing permissions.
All videos taken on same camera.
digiKam set to write to sidecar for read-only images.
Any ideas on why is this happening?
