Description Dmitry Nezhevenko 2025-04-28 10:03:56 UTC 
SUMMARY
It would be cool to have support for non-destructive video rotation using XMP sidecars file. Exactly same as it's currently implemented for photos.

Note that video itself may have 'rotation' flag that was wrong

STEPS TO REPRODUCE
1. Start video capture on phone in portrait mode and them immediately rotate it to landscape
2. Import to digikam, observe that video is in 'portrait mode' (expected default)
3. Rotate video using "Ctrl+Alt+Left/Right" hotkey 

OBSERVED RESULT
`tiff:Orientation="1"` is written to XMP file. Thumbnail is rotated

Player itself still plays video in portrait mode

EXPECTED RESULT

Embedded video player should automatically rotate video in a same way like thumbnail (basically same thing as right click on it) 

SOFTWARE/OS VERSIONS
KDE Plasma Version: 6.3.4
KDE Frameworks Version: 6.13.0
Qt Version: 6.8.2

ADDITIONAL INFORMATION
Comment 1 Maik Qualmann 2025-04-28 10:32:46 UTC 
I can't reproduce this with the Qt6 version of digiKam. A video rotating over the XMP sidecar is played in the correct orientation.

Which version of digiKam are you using exactly?

Comment 2 Maik Qualmann 2025-04-28 10:39:22 UTC 
Okay, if it has a counterclockwise rotation in the metadata, it won't play correctly aligned. I'll take a look.
