Bug ID: 517606
Summary: Screenshot functionality completely broken
Classification: Applications
Product: Haruna
Version First 1.7.1
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Description
Steps to reproduce:
Install Haruna 1.7.1 on Arch Linux (fresh install)
Open any video file (tested with .mp4, .mkv)
Press 's' (default screenshot key) or click screenshot button in GUI
Observe "Screenshot failed" message in top-left corner of video
Expected behavior:
Screenshot should be saved to the configured directory (default:
~/Pictures/Haruna Screenshots/)
Actual behavior:
Screenshot fails every time regardless of format (PNG/JPG/WEBP)
Error message "Screenshot failed" appears on video overlay
No screenshot file is created
Terminal output shows: QIODevice::read (QProcess): device not open
Additional observations:
mpv itself (the backend) CAN take screenshots normally when run
independently
Screenshot directory is writable (Haruna creates it automatically)
This is NOT the known 0.11.0 uppercase/lowercase config bug (that was fixed
long ago)
The error suggests a Qt QProcess communication failure between Haruna and
the mpv backend
Haruna appears to be using startDetached() or similar instead of properly
maintaining the process channel
Terminal output:
text
$ haruna
unknown() : QIODevice::read (QProcess): device not open
Cannot load libcuda.so.1
unknown() : KFileFilterCombo::setCurrentFilter: Could not find file filter
KFileFilter(MIME patterns: QList() File patterns: QList("*") label: "所有文件")
Attempted fixes (none worked):
Changed screenshot format/directory multiple times
Verified mpv works independently
Checked file permissions
Reinstalled both Haruna and mpv
