Bug ID: 495145
Summary: baloo_filemetadata_temp_extractor causes dolphin to
freeze when large files are scanned for details
Classification: Applications
Product: dolphin
Version: 24.08.2
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: panels: information
Assignee: dolphin-bugs-n...@kde.org
Reporter: a.skemb...@gmail.com
CC: kfm-de...@kde.org
Target Milestone: ---
SUMMARY
When accessing a folder with large video files (>5 Gb at least), dolphin will
freeze for a few seconds. According to the system monitor output, this happens
while baloo_filemetadata_temp_extractor is parsing the files to extract details
that are usually shown in the "Information" side panel (e.g. dimensions,
duration, etc.) (System monitor shows large read rates from
baloo_filemetadata_temp_extractor).
The effect is annoying on an SSD, but makes Dolphin practically unusable in the
case of HDDs (which I am using in this case, as the video files are quite
large, I have a lot of them and I don't particularly care about writing
speeds).
Note that I have disabled file indexing and set the threshold for the option
"Show previews" to files below 100Mb) (although I think this refers to the icon
thumbnails, not the "Information" metada?)
As a workaround, I renamed the executable
/usr/bin/baloo_filemetadata_temp_extractor so that it stops parsing the files.
I don't get any metadata in the "Information" any more, but it beats not being
able to use Dolphin at all (for these folders, at least).
STEPS TO REPRODUCE
1. Place large (>5 Gb) video files in a folder, probably multiple such files.
2. Open the folder using Dolphin
3. Click or hover over any of these files.
OBSERVED RESULT
Dolphin freezes for a few seconds until it extracts the metadata from the
files.
EXPECTED RESULT
I would expect Dolphin to remain responsive or not to extract the details of
these files, as these files exceed the "Show previews" threshold I have set (I
am fine with not seeing the details for so large files since parsing to extract
metadata takes a while).
