As a workaroun, turning ENABLE_MEDIAPLAYER to off works: cmake -DENABLE_MEDIAPLAYER=off .. I don't know how your ubuntu ffmpeg codecs are compiled. I suspect a problem with these components which are used to extract video thumbnails. To be sure, download current 5.8.0 pre-release Linux AppImage and try to display video ablmum contents with this version instead your system based digiKam. https://files.kde.org/digikam/ Gilles Caulier Using ./digikam-5.8.0-20171212T132305-x86-64.appimage had no issues with the same video files. As you stated, must be some problem with my ffmpeg codecs that I compiled. Could I ask which version of ffmpeg current appimage is using? To build AppImage bundle, we use Centos6 for binary compatibility with libc. We use the Centos6 RPM taken from an extra repository : http://li.nux.ro/download/nux/dextop/el6/x86_64/ Gilles Caulier Big thanks! I solved my problem which indeed was a problem with my ffmpeg libs. I happen to have a mixture of install devlibs from the distro, as well as my own compiled ffmpeg libs. When I removed the distro ffmpeg libs, Digikam now plays video nicely. Nice to hear... Thanks for the feedback and happy new year. Gilles Caulier |
