Description Martin Riethmayer 2017-01-29 10:18:03 UTC

(Possibly related to https://bugs.kde.org/show_bug.cgi?id=364531 ?)
Application: kdenlive (16.08.2)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.36-8-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:

I used a short (hand-filmed) video clip (2048x1162) in a Full-HD project in Kdenlive. I then applied the "deshake" filter to the video and set "rx" and "ry" to 24 (other settings unchanged). When the preview is supposed to be updated (e.g. by clicking on some time in the timeline), Kdenlive crashes.

If I set "rx" and "ry" to 16 or 32, Kdenlive does not crash. I also tried "8" and "20" both do crash Kdenlive.

If I'm reading http://ffmpeg.org/ffmpeg-filters.html#deshake correctly (and if I am correct that Kdenlive deshake == ffmpeg deshake), valid values are 0-64. 

BTW: The default for rx and ry is "16" according to the website, but is set to "0" in Kdenlive - I don't know if that's on purpose or not.

The crash can be reproduced every time.

-- Backtrace:

Comment 2 Martin Riethmayer 2018-06-21 08:00:57 UTC

Still crashing in Kdenlive 17.11.80 on KDE Neon User:

KDE Plasma 5.12.2
KDE FW: 5.48.0
Qt: 5.11.0
Kernel: 4.13.0


Also crashing in Kdenliv 18.03.70 on KDE Neon Git unstable as of today:

KDE Plasma 5.13.80
KDE FW: 5.48.0
Qt: 5.11.0
Kernel: 4.13.0

Comment 3 emohr 2018-12-29 19:40:45 UTC

Tested on Refactoring version. It doesn’t crash anymore. 

But it seems Deshake do’s nothing nevertheless which parameter I change.

Changed to normal and AppImage_Refactoring.

Comment 4 farid 2021-03-07 13:39:32 UTC

The deshake effect is broken and has been removed during our effect cleanup task. Read more about it here: https://invent.kde.org/multimedia/kdenlive/-/issues/350

Closing since it is an upstream issue and not valid anymore. Thanks for reporting.
