Kdenlive Crashes on Start with GPU Acceleration, Ubuntu 23.04 with RTX3050

otterslide · September 8, 2023, 6:49pm

Any ideas what I can do to get GPU acceleration enabled on Ubuntu?
I tried Kdenlive AppImage and Flatpak, and they both crash on startup once I enable GPU processing.
I tried installing libmlt7 livmovit8 and librtaudio6 , but nothing changed. Kdenlive 22 doesn’t have the checkbox enabled. Kdenlive 23.x allows checking, but crashes on startup.
I have Nvidia drivers installed, tried multiple versions also.

Yes, this is a known issue which is going to be addressed eventually. In the meantime GPU acceleration is not stable so refrain from using it atm.

Umm… This has been a known issue for years. I’m finding user posts regarding this issue that date back 7 years. [kdenlive] [Bug 375713] New: Kdenlive crashes if GPU processing (Movit library) is enabled

frdbr · January 15, 2024, 8:41pm

Yes, there is so much a small team can do in their spare time. In the meantime help would be appreciated or at least patience…

Do you guys know the root cause of the crash?

I am available to test and compile versions to fix this issue.
I have several rigs and GPU accelerated VMs to help with testing.

All my systems are on Pop!OS

AMD GPUs, with MESA + ROCm stacks
RX 5700xt
RX 580 4GB
AMD Renoir eGPU

Nvidia GPUs with Pop!OS Nvidia proprietary preinstalled drivers
MX150 hybrid graphics
An old Nvidia Quadro but I can’t remember the model number

If you give me some instructions, I can test

I have no issue spawning VMs with other OS configurations if needed

Also, I’ve seen conflicting information online…
Is it caused by the fact that movit is not compatible with the version of Qt that ships with KDEnlive ?

If so, here might be a way o re-package the Flatpak to include a compatible version, even if older.
