SUMMARY In slide show, video stutters every ~10seconds when played from external HD. Speed should not be an issue as I get 100MB/sec transfer rates when copying files (USB 3.0 connection). STEPS TO REPRODUCE 1. Play slide show that contains videos from external HD OBSERVED RESULT At the beginning of each video and then every maybe 10sec the video gets slow and stutters before running smoothly again. It LOOKS like a buffer underrun, but I can't find where to adjust the buffer size (if that is even configurable). EXPECTED RESULT Smooth playback, as it does when starting playback from the album. SOFTWARE/OS VERSIONS Ubuntu 18 Other info I am using the built in graphics device, not a separate card (this is my 24/7 "house computer" and I try to keep power consumption low). The CPU is an i7 with 3500MHz, I've got 16GB of RAM. I looked at bug 382582, but am not really sure if my problem has to do with my hardware or not having the right decoders (would I need to compile these in? ...though compiling my software is not my cup of tea) or buffering (to me, it looks like the latter).
It must be the same in preview mode while playing video. right ?

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 bundles. Gilles Caulier
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.
