Bug ID: 423580
Summary: video playback stutters on some file formats.
Product: digikam
Version: 7.0.0
Platform: Kubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Preview-Video
Assignee: digikam-bugs-n...@kde.org
Reporter: deanob...@gmail.com
Target Milestone: ---
SUMMARY
.avi and .mpeg file playback is stuttered and occasionally without sound. All
other video file formats play perfectly. The last appimage to play all file
formats for me with sound was 6.0.0. Update 6.1.0 fixed the file playback
issues but no video format had any sound. Updates from 6.3.0 fixed the sound
issue but had stuttered video playback with .avi and .mpg while mp4 .mkv and
.wmv all played without issue.
STEPS TO REPRODUCE
1. Take any sample video clip and export from kdenlive into different
containers (.avi, .mpg, .mkv & .mp4)
2. Add that folder to the collections
3. Click each video and preview.
OBSERVED RESULT
The .avi will stutter or have no sound, the .mpg will stutter and may have
sound, the .mkv and .mp4 will play fine and have sound.
EXPECTED RESULT
All videos should play in preview
SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.12.9
KDE Frameworks Version: 5.44.0
Qt Version: 5.9.5
Kubunu 18.04 ffmpeg version 3.4.6
ADDITIONAL INFORMATION
All video files will play fine in QtAV player or VLC player. The effect does
not depend on file location, local files and files on USB drives show the same
issues. The avi file may play back stuttered and have no sound or play back
fine and have no sound, I haven't been able to establish which export settings
create the different results.
