Bug ID: 375998
Summary: kdenlive project monitor plays audio only for 2-4
seconds then crashes
Product: kdenlive
Version: 16.08.2
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: User Interface
Assignee: j...@kdenlive.org
Reporter: ray.we...@googlemail.com
Target Milestone: ---
Application: kdenlive (16.08.2)
Qt Version: 5.7.1
Frameworks Version: 5.29.0
Operating System: Linux 4.9.6-200.fc25.x86_64 x86_64
Distribution: "Fedora release 25 (Twenty Five)"
-- Information about the crash:
- What I was doing when the application crashed:
I was playing a clip in the project monitor, trying to see if a transition
looked right. This was entirely useless (as always) because the monitor skipped
over the section I was interested in, playing audio with a still image.
I tried again, clicking in area in the timeline before the transition I want to
see, and then pressed play again. The audio started playing nearly a minute
later in the clip, but neither the project monitor window nor the current
position indicator moved. After 3-4 seconds, the application exited.
On restart, it complains that 1 clip is missing its proxy clip, and one clip
could not be found. The path shown for that clip was relative to my home
directory, not the project folder. I used "search recursively", selecting the
project folder, and it found the clip.
On playing in the project monitor (in the same place or a different place) it
crashes again (playing 2-3 seconds of audio from a different part of the
project and then exiting). Usually takes 15-20 restarts before it starts
working properly again; a full reboot or opening a different project makes no
difference.
Quite often, one of these crashes is followed by a "clip not found" report when
the same project is opened. Once a clip has been not found (and then found
using "Search Recursively") the same file will be not found the next 4-8 times
I open that project, even if I save the project file after it's found it.
Sometimes the displayed paths are relative to the project folder, sometimes to
my home directory. The clips in question had all loaded correctly when the
project was previously edited, and were not near the current position at the
time of the crash. So I'm not sure if these issues are related or not.
The crash can be reproduced sometimes.
