Video Converter MKV error

[AliceT50]

Hi!
I get an issue with the video converter for a matroska video file.
First, the software tell me that ffmpeg was not installed (I've done that before, but seems to installed others packages, just don't care).
When I put an output path (which is correct) and load a .mkv input file, no errors. Finally, at the convert step, it returns me this window :

I don't understand how and when did it estimate this, but as result just a file with 0 Bytes...
I've already searched for an issue like this, but nothing.

ffmpeg.x86_64 7.0.2-4.fc41 rpmfusion-free - Fedora 41 (KDE Plasma Spin) - Fresh install (since yesterday...)

Hello!
Can you please share the output of the below command?

davinci-helper/davinci-helper/davinci_helper/functions/logic/conversion_settings.py

Line 132 in b657234

result = subprocess.run(f'ffprobe -v error -select_streams v:0 -show_entries stream=width,height,duration,avg_frame_rate -of json "{file}"', stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True, shell=True)

(it doesn't have to be json, just normal text would be preferred)

Hi!
Sure, I tried to rearrange the command to work directly in my terminal, and there is the output :
❯ ffprobe -v error -select_streams v:0 -show_entries stream=width,height,duration,avg_frame_rate -of json "/home/athierry/Vidéos/video.mkv"
