Description cadengamez 2017-05-19 19:07:56 UTC
Application: kdenlive (17.04.1)

Qt Version: 5.8.0
Frameworks Version: 5.34.0
Operating System: Linux 4.10.13-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I put a "Fade from black" effect on an image (PNG, 1920x1080) and when you play the video kdenlive crashes.
- Custom settings of the application:
GPU Processing was enabled.

The crash can be reproduced every time.

NOTE: The crash reporting wizard could not submit the report, so I am doing it manually through the website. 

-- Backtrace:
Application: Kdenlive (kdenlive), signal: Segmentation fault

I am using arch and can't reproduce. Test with GPU disabled...
Comment 2 cadengamez 2017-06-05 02:31:28 UTC
(In reply to farid from comment #1)
> I am using arch and can't reproduce. Test with GPU disabled...

For me, the crash only occurs if GPU is enabled.
Comment 3 Jakob Sinclair 2018-09-10 18:44:12 UTC
Can reproduce this issue when GPU is enabled. Every time I add Fade from Black to a video or image it instantly crashes. I don't have debug packages on Solus so I can't provide a backtrace.

Actually got a backtrace here:

Unfortunately MOVIT (GPU effects) is not stable and not ready for production use.
Comment 6 Vincent PINON 2018-09-11 20:38:09 UTC
Movit's *integration in MLT* is not stable.
I believe the lib itself is quite seriously tested (at least on some configurations of graphics cards & drivers), but MLT wrapping has been mainly a one-shot sprint.
The crash backtrace confirms the error is in libmltopengl.
Can you forward the issue to MLT on github?

New crash information added by DrKonqi

kdenlive (18.04.3) using Qt 5.11.1

When i press pause (space key), the preview video stop but when i press play (space key) again, kdenlive just crash, even so the process of kdenlive and file.so keep running and i have to go kill them with ksysguard.

Thanks for posting. A dev is working on the integration of MOVIT and GPU acceleration. But it seems not so easy to fix it. Can’t say by when he get a stable MOVIT version.

Movit is experimental and will only be worked on after the Qt6 upgrade...
