FFmpeg exited with code: 8 and signal: null

Describe the bug
Hello, I have been stuck on a problem for 2 days.
I would like to install 2 cameras of the brand "Imou" in the home application on my iPhone.
So I installed homebridge on my Ubuntu (Ubuntu is installed on a raspberry pi 5) and I also installed camera.ui in order to configure my cameras.
First I retrieved the RTSP URL addresses of my cameras and I checked that they work well in VLC.
So I configure the plugin and add my cameras, I enter the RTSP address, I activate the audio and I restart my plugin.

If I go to the camera.ui interface I see my 2 cameras and they are functional. However if I add my 2 cameras to Homekit it is displayed well in it, I also have the thumbnail but if I launch the live video stream it loads infinitely and in the homebridge console I have the following error: "FFmpeg exited with code: 8 and signal: null"

(I installed ffmpeg on my ubuntu with the command "sudo apt install ffmpeg" but that doesn't change anything)

I don't know what to do to resolve this error...

before that I tested the installation of homebridge on my raspberry pi 5 in several ways:

• Homebridge installed on raspberry os
• Homebridge OS

It was the same problem with also other problems in addition like the "Restart video analysis" in loop

before buying my raspberry I had done the test on a windows 11 VM in Manager Hyper V and it worked perfectly well, no errors, access to my cameras in the interface camera.ui but also in Homekit.
I don't understand why it works in a Windows 11 VM but not on my raspberry because the configuration is exactly the same.
I wanted to buy a raspberry to make a homebridge but I find myself unable to make my cameras work in homekit.
