Bug ID: 438760
Summary: Animation: render in failure when when autosave is
triggered
Product: krita
Version: nightly build (please specify the git hash!)
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Animation
Assignee: krita-bugs-n...@kde.org
Reporter: grum...@grum.fr
Target Milestone: ---
As asked in bug https://bugs.kde.org/show_bug.cgi?id=382418, I create a new one
because I confirm that on my side autosave action stop animation render.
Currently on Krita 5, if autosave run while an animation is rendering, render
is stopped with a popup message "failed to render animation frames”.
STEPS TO REPRODUCE
1) Create an animation for which time to render is long enough to have autosave
triggered
2) Ensure that document is in modified state (ie: the autosave will be
triggered)
3) Render animation
OBSERVED RESULTS
Render is interrupted, there’s a status bar notification "autosaving postponed:
document is busy" but rendering continues.
A couple of seconds after, there's a new notification.
This is repeated 4 times and then finally, autosave is applied.
A dialog box "waiting for image operation to complete (<updating>)" is
displayed for a couple of seconds and it stops the rendering with a "failed to
render animation frames" message.
EXPECTED RESULTS
If an animation is rendering:
- the autosave should properly be cancelled without stopping render
or
- the autosave should be temporary disabled before animation is rendered, and
enabled once rendering is done (if enable before rendering)
ADDITIONAL INFORMATION
"""How many frames Krita is trying to render (viewable on the render progress
bar as [currentFrame]/[totalFrameCount].)"""
This part have no importance...
It occurs with 2 keyframes on my side as well as hundred of keyframes.
Total number is around 600frames on my test but I think it means nothing as
from a simple animation of 600 frames it could 15s to render all frame to more
than one hour for a more complex 600frames animation.
"""How many cores your system has dedicated to rendering animations or caching
frame data (should be viewable on the performance tab.)"""
from 1 core to 24 Cores, the problem occurs.
Last test as been made with 4 cores
"""Does the failure occur when saving image sequences or does it occur during
the FFMPEG phase (You can verify by checking if all image frames have rendered
out properly and saved to that hard disk.)"""
Rendered as PNG sequence, then no ffmpeg involved in process
Tested on krita-5.0.0-prealpha-dba5ce5-x86_64.appimage and many other pre-alpha
version
