            Bug ID: 443228
           Summary: Animated GIFs do not play in Presentation mode
           Product: digikam
           Version: 7.3.0
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: Plugin-Generic-Presentation

  Target Milestone: ---

SUMMARY

Hello,

When I start a presentation via View > Presentation... , any animated GIFs in
the image selection do not play, instead only the first frame of the GIF is
displayed.

This is contrary to Slideshow mode, where animated GIFs do play. In Slideshow,
an animated GIF will play for it's entire duration, regardless of the slideshow
delay setting. So e.g. if I have a GIF that's 4 seconds long and my slideshow
is set at 2 seconds interval, the GIF will still take up 4 seconds.

I think Presentation mode should play animated GIFs and have an option to
either play the GIF to completion, or play the GIF up to the presentation
interval time, and then move on to the next image. This is consistent with how
nomacs handles presentations/slideshows with animated GIFs.

I am using digiKam 7.3.0.

Thanks!

STEPS TO REPRODUCE
1. Add some animated GIFs to your library
2. Start Presentation
3. Observe GIFs are not animated

OBSERVED RESULT

Animated GIFs in Presentation just show first frame.

EXPECTED RESULT

Animated GIFs in Presentation should be animated.

SOFTWARE/OS VERSIONS 
Linux: 5.14.8
KDE Plasma Version: Unknown (using i3wm)
KDE Frameworks Version: /unknown (using i3wm)
Qt Version: Unknown (whatever digiKam 7.3.0 in Arch is built against)

ADDITIONAL INFORMATION

Not tested yet in 7.4.0 but I can give it a go.
