ffmpeg error details
SUMMARY
***
I use Fedora 38 and I have Kdenlive 23.08.0 installed via flatpak. I use Gnome
with Wayland.
When I open the application I see a notification popping up at the top of the
screen, saying:
"Oops! We're sorry, it looks like ffmpeg crashed"
Kdenlive application remains running, but that notification is shown again from
time to time. For example, when I go to "Run config wizard", the notification
is raised again.
***
STEPS TO REPRODUCE
1. Install Kdenlive 23.08.0 from Flatpak in Fedora 38 with Gnome
2. Open Kdenlive, you'll see the ffmpeg crash report at the top
3. Alternatively, open "Run config wizard" option in Kdenlive, it will show the
ffmpeg crash notification at the top.
OBSERVED RESULT
It's raising a ffmpeg crash notification at the top.
EXPECTED RESULT
No error notifications.
SOFTWARE/OS VERSIONS
Fedora 38 with Gnome
ADDITIONAL INFORMATION
When I go to view the details of the ffmpeg error, I can see:
ffmpeg killed by SIGSEGV
cmdline: /app/bin/ffmpeg -hide_banner -f lavfi -i color=s=640x360 -frames 1 -an
-c:v av1_nvenc -f rawvideo pipe:
When I do:
flatpak run --command=sh --devel org.kde.kdenlive
Then:
/app/bin/ffmpeg -hide_banner -f lavfi -i color=s=640x360 -frames 1 -an -c:v
av1_nvenc -f rawvideo pipe:
I can see this output:

I have 2 GPUs here:

As you can see above I don't have Nvidia on my system. But it appears to be
looking for a cuda library?
