This is not a bug. See the FAQ, Usage question 15.

You need to set your detect width and height manually, or better yet, use go2rtc for your live views.

[brianfeucht]

Thanks! I didn't see this release FAQ. I was looking on the doc page =)

I've updated the camera config to:

cameras:
  WestGate:
    webui_url: http://192.168.1.6/
    ffmpeg:
      inputs:
        - path: rtsp://##:###@192.168.1.6/cam/realmonitor?channel=1&subtype=0
          roles:
            - record
        - path: rtsp://##:###@192.168.1.6/cam/realmonitor?channel=1&subtype=2
          roles:
            - detect
    audio:
      enabled: false
    motion:
      mask:
        - 1725,75,1840,75,1840,29,1725,29
    detect:
      width: 1920
      height: 832
      fps: 5

Still seeing the same issue. I'll try switching live view to go2rtc later today.

[hawkeye217]

1920x832 is an odd resolution. What happens if you change it to 1920x843 or 1920x844?

[brianfeucht]

It is a dual lens camera that stiches the two together

I switch the live and detect feeds to a go2rtc stream and it resolved the issue.

Happy to switch back if you'd like to troubleshoot further.

[hawkeye217]

Ah, that would make sense then. No need to switch back. Go2rtc is the recommendation over jsmpeg anyways.

[brianfeucht]

Switching to a go2rtc feed resolved this for me

[ChirpyTurnip]

Hi @brianfeucht!

I think I have the exact same camera (180 degree Dahua / EmpireTech), so I am stuck with exactly the same problem. It's good to know switching to go2rtc fixed it for you but I'm having a few issues as I'm running two instances of Frigate on Unraid for two different camera installations. Sometimes I have conflicts between the two setups...so troubleshooting can be really hard.

For those of us similarly stuck would you mind sharing your updated config? If I can see a config that should definitely work with my hardware that would be super helpful!

Thanks!

CP.

[brianfeucht]

@ChirpyTurnip yes, happy to share 😄

On the camera I have sub stream 1 disabled as it doesn't provide the resolution I want for detection. If you want audio detection, be sure to enable audio on substream 2 (it is disabled by default)

That was perfect! I still have some other issues to sort out, but the cameras are now all connected, with sound, and no color distortions! So good progress thank you!
