In my current 5.4.0 appimage, I can use Shift+Ctrl+Cursor to rotate video thumbnails. But the video itself isn't rotated. Either the video orientation should be adjusted (I think Qt5Multimedia supports video orientation flags) or the thumbnail rotation should just be ignored - if many thumbnails are selected and one of them is a video, just this video thumbnail should not be rotated. And if the rotation is actually supported, the thumbnail should be recreated with the "movie" overlay again at the side of the thumbnail. Right now, after rotation, the overlay is at the top or bottom (inconsistent). Thank you :)
Qt5Multimedia is not used anymore. QtAv is used instead. Gilles Caulier
For version 5.6.0 on Windows 7 SP1 / 64 bit I can confirm this bug: I can use Shift+Ctrl+Cursor or the right muse button menu to rotate video thumbnails. But the video itself isn't rotated. For the release of version 5.4.0 it says (on https://www.digikam.org/news/2017-01-10_digiKam_5.4.0_is_released/): "...we were able to add new features like video rotation in preview and video slideshow." Sounds as if this wanted to indicate a solution _in addition_ to thumbnail rotation. Also - but perhaps unrelated - I noticed that the digikam program folder holds a QtAV1.dll as well as Qt5Multimedia.dll. This was a clean first-time install. Dietrich
