Description Rafael Linux User 2018-01-03 03:28:18 UTC
When I try to play videos (mp4) correctly encoded and played thru Dragon Player, SMPlayer or VLC, the video is played like in slow motion, not at normal speed.

Please, how can I solve this?

Thank you

Please, try 5.8.0 pre release bundle AppImage :

Note : digiKam use QtAv + ffmpeg codecs to play video. did you install a native opensuse ffmpeg version including mp4 codecs support ?

Comment 3 Rafael Linux User 2018-01-03 23:00:30 UTC
With the AppImage version, video are played perfectly synchronized, played in real time.

About QtAv, I have installed some libraries, but not QtAv framework or player:

i+ | libQtAV1                  | QtAV library
i+ | libQtAVWidgets1           | QtAV Widgets module

and about ffmpeg, this is what I have installed:
zypper se ffmpeg | grep i+
i+ | ffmpeg                                    
i+ | ffmpegthumbs                              
i+ | gstreamer-0_10-plugins-ffmpeg             

Should I install something more?

In all cases, you can install also the qtav video player and try to play the mp4 files. It must work as with the digiKam AppImage bundle. If not report this problem to OpenSuse team as DOWNSTREAM. It's not definitively a problem from digiKam.

I installed  QtAV, QtAV-players and QtAV-qml , but it didn't solved the
issue. I will notify to OpenSUSE.

Thank you

Comment 7 caulier.gilles 2020-01-12 10:50:50 UTC
There is a patch applied to QtAV for this problem in current implementation from git/master :

https://github.com/wang-bin/QtAV/pull/1268

So, i will take a look to integrate this change in digiKam bundles.

Git commit 5aae9b7c21ab662d63b49f165163984809c1d585 by Gilles Caulier.
Committed on 12/05/2022 at 11:10.
Pushed by cgilles into branch 'master'.

Move AVPlayer config widgets to core/QtAV to allow to re-use these settings view in a new Video section from digiKam Setup dialog.
the goal is to be able to configure the video decoder, the audio backend, and the video renderer with video preview framework,
to prevent dysfunctions while playing audio and video media if wrong decoder/backend/renderer is selected by default.

Currently none of these settings is possible in digiKam and playing video and audio always depends of default settings done in QtAV
framework which can be badly configured for the available hardwares and modules in client computer.

TODO: add the new video config pannel in digiKam Setup dialog to configure decoder/backend/renderer.
