Description Nikolaus 2016-12-05 02:36:45 UTC

Digikam 4.13 able to play video files. After upgrading to Digikam 5.3.0, I only get a placeholder image and the following message on the console:

digikam.metaengine: Cannot load metadata from file   (Error # 11 :  /home/nikratio/lib/Dropbox/Camera Uploads//2016-11-14 00.23.16.mp4: The file contains data of an unknown image type

I'm using the 5.3.0 appimage on Debian stable.

Comment 1 caulier.gilles 2016-12-05 05:58:14 UTC

Since digiKam 5, we use QT5::Multimedia to handle video, which use GStreamer under Linux. Thumbnails can be displayed and video played if you install GStreamer codecs (base, good, bad, and ugly).

I have the gstreamer codecs installed, and parole (which uses gstreamer) is able to play the files.

But that said, shouldn't the codecs be included in the AppImage?

Git commit 32ebb7dff83b03cfad91cbe89de252b1f62bdd6e by Gilles Caulier.
Committed on 11/12/2016 at 12:02.
Pushed by cgilles into branch 'master'.

digiKam embeded mediaplayer is now based on QtAV/ffmpeg instead Qt5Multimedia.

TODO:

- handle video rotation flag with new Exiv2 0.26 to autorotate media in player.
- port video thumbnailer to QtAV.
- port Presentation audio player to QtAV.
- remove Qt5Multimedia dependency.

For later:

- play video into slideshow tool.
- port old videoslideshow tool to QtAv
