Raspberry Pi v3 NOIR Camera - Config Being Halted?

[MattGeale]

Manufacturer/Model: Raspberry Pi Noir v3 Camera

Homebridge Config:

        {
            "name": "livestream",
            "cameras": [
                {
                    "name": "livestream",
                    "unbridge": true,
                    "videoConfig": {
                        "source": "-i rtmp://172.22.20.81:1935/live/app",
                        "stillImageSource": "still -video_size 1920x1080 -input_format mjpeg"
                    }
                }
            ],
            "_bridge": {
                "username": "<mac addr>",
                "port": 34354
            },
            "platform": "Camera-ffmpeg"
        }

Additional Information: This might not be something to do with the homebridge service, and might not be anything to do with the ffmpeg config on homebridge so apologies if not. Anyway, the following is the script that I use to livestream the footage from the pi to homebridge. When the script first launches, runs like a tank. No issues. Only when exiting the stream, it errors with exit code 1.

Width=1920
Height=1080

Framerate=24

Bitrate=3500000

Preset=veryfast

HDR=0

libcamera-vid -t 0 -n --inline \
 --width $Width --height $Height \
 --framerate $Framerate \
 --hdr $HDR --bitrate $Bitrate -o - | \
ffmpeg -re -f lavfi -i anullsrc -c:a aac -r 30 \
-i pipe: -g $(($Framerate * 2)) \
-strict experimental -vcodec copy -map 0:a -map 1:v -b:v $Bitrate -preset veryfast \
-f flv -listen 1 rtmp://0.0.0.0:1935/live/app

Whenever I stop watching the stream on either VLC or on homekit, I get this error:

Any help would be hugely appreciated <3

I’m not sure I fully understand your setup, but it looks like it’s probably an issue with livestream.sh?

Livestream.sh is the above script. I thought that could be it, but I'm not 100% sure what it could be.
