Bug ID: 415778
Summary: In slide show, video stutters every ~10seconds when
played from external HD
Product: digikam
Version: 6.4.0
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: Plugin-Generic-SlideShow
Assignee: digikam-bugs-n...@kde.org
Reporter: ctre...@gmx.net
Target Milestone: ---
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).
