Which operating system are you using?

Linux arm64 standard

Describe how to replicate the issue

I'm using a Raspberry Pi 5 Bookworm + HQ Camera to stream with the following config:

paths:
  cam:
    source: rpiCamera
    rpiCameraWidth: 1920
    rpiCameraHeight: 1080
    rpiCameraFPS: 25
    rpiCameraMode: "2028:1080:12"
    rpiCameraCodec: softwareH264
    rpiCameraBitrate: 5000000
    rpiCameraProfile: main
    rpiCameraLevel: "4.1"

When starting the server the following output is logged:

The selected profile is Constrained Baseline, level 4.0 despite main being specified in the config.

Do the codec parameters not get correctly passed to x264?
