Digikam 5.4 uses QtAV for video thumbnails and viewing. The fedora package is built without QtAV support Version-Release number of selected component (if applicable): 5.4 See: https://kojipkgs.fedoraproject.org//packages/digikam/5.4.0/1.fc25/data/logs/x86_64/build.log -- Could NOT find QtAV (missing: QTAV_LIBRARIES QTAV_INCLUDE_DIRS) -- QtAV_FOUND = FALSE -- QtAV_INCLUDE_DIR = QTAV_CORE_INCLUDE_DIR-NOTFOUND QTAV_WIDGETS_INCLUDE_DIR-NOTFOUND -- QtAV_LIBRARIES = QTAV_CORE_LIBRARY-NOTFOUND;QTAV_WIDGETS_LIBRARY-NOTFOUND ... -- libqtav found............................ NO (optional) -- digiKam will be compiled without Media Player support. -- Please install the libqtav (version >= 1.11.0) development package.
digikam upstream use of QtAV is effectively nonfree (with ffmpeg dependencies), so we cannot enable that feature in fedora. sorry, cantfix :(
Ok. Thank you for the reply. You could write a note into the README file. This could spare someone from searching for missing deps or other settings.
