            Bug ID: 491990
           Summary: Software closes abruptly while playing video.
    Classification: Miscellaneous
           Product: unknown
           Version: unspecified
          Platform: Debian stable
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: ejmillan at outlook.es
  Target Milestone: ---

Application: subtitlecomposer (0.8.0)

Qt Version: 5.15.13
Frameworks Version: 5.115.0
Operating System: Linux 6.8.0-41-lowlatency x86_64
Windowing System: X11
Distribution: Ubuntu 24.04 LTS
DrKonqi: 5.27.11 [KCrashBackend]

-- Information about the crash:
Editing and modifying subtitles based on srt file.
Reference video file has AC3 Dolby Digital audio (6 ch)
At one point while playing the video, the program abruptly closes.
It always happens at the same point. The srt file is in ISO 8859-1 format.
If I select a subtitle after the timeline of that point, the program also
closes.
I will carry out tests by converting the video file to another codec, container
or even changing the audio file to 2 channels and lower bandwidth.
I am interested in generating the synchronized srt file and then adding it to
the original video by multiplexing in MKVToolnix. So far the crash prevents me
from finishing the edit.

The crash can be reproduced every time.

-- Backtrace:
Application: Subtitle Composer (subtitlecomposer), signal: Segmentation fault
