[Camera Support]: Unifi G4 Doorbell has incorrect thumbnail and live stream for package camera.

[BrandonShega]

Describe the problem you are having

I have a G4 doorbell which has 2 cameras - the doorbell camera and a package camera. I have enabled RTSP streams for both of these and correctly configured them and they work the problem is that whenever I refresh the page sometimes I get the doorbell camera thumbnail/livestream and sometimes the package camera. The strange thing is that the recording is working fine, it always records the package camera. Another strange thing is that when I view recordings, the live view thumbnail still shows the doorbell camera instead of the live view of the package camera.

Clicking on the camera always gives me a live stream of the doorbell camera and never of the package camera. History shows the package camera correctly though.

Your issue involves the live view showing inconsistent streams between the doorbell and package cameras. Based on your configuration, there are several areas that need attention.

First, your front_door_package camera configuration is missing a recording role.(1) You have:

cameras:
  front_door_package:
    enabled: true
    ffmpeg:
      inputs:
        - path: rtsp://127.0.0.1:8554/front_door_package
          roles: [detect]

(1)

This camera only has the detect role configured, but you mentioned recordings work correctly. To properly configure both detect and record, you should add the record role:(1)

cameras:
  front_door_package:
    enabled: true
    ffmpeg:
      inputs:
        - path: rtsp://127.0.0.1:8554/front_door_package
          roles: 
            - detect
            - record
      output_args:
        record: preset-record-ubiquiti

(1), (2)

Second, regarding your live view configuration, you've set up multiple streams correctly in the live section:(3)

live:
  streams:
    Front Door: front_door
    Package Cam: front_door_package

(3)

However, when you have multiple streams configured, Frigate's default dashboard ("All Cameras") will always use the first entry defined in streams.(3) To change which stream displays, you'll need to use a camera group instead of the default dashboard.(3)

For the inconsistent thumbnail/live stream behavior you're experiencing, this could be related to how go2rtc is handling the stream selection. When you click on a camera from the dashboard, Frigate attempts to display the live stream using the configured go2rtc streams.(3)

Since both your front_door and front_door_package go2rtc streams are pulling from the same UniFi device (10.10.1.1:7441), there might be stream selection issues. Verify that your RTSP URLs are correctly pointing to the specific camera streams - the doorbell camera versus the package camera.(4)

For UniFi cameras, ensure you're using the correct stream paths for each camera.(4) The rtspx:// protocol you're using should point to distinct streams for each camera view.

Additionally, the errors in your logs suggest preview generation issues:(3)

Error saving preview for front_door_package :: [concat @ 0x5eb6d42b6180] Impossible to open '/tmp/cache/preview_frames/preview_front_door_package-1767811210.16913.webp'

This could contribute to thumbnail display problems.

To troubleshoot further, access the go2rtc web interface at port 1984 and verify that both front_door and front_door_package streams are receiving the correct video feeds.(5) Navigate to <frigatehost>:1984 and click "stream" for each camera to confirm the streams are properly separated.(5)

Your live --> streams directive should not be defined at the global level of your config. It should be defined at the camera level. But since you only have a single stream per camera and you already match the camera names with the go2rtc stream names, I would remove it entirely. This is what is causing your issue.

[BrandonShega]

Hmm, I did that and now Frigate won't start :(

[hawkeye217]

The logs will indicate why Frigate isn't starting.

[BrandonShega]

Disregard, I'm not sure what actually happened with Frigate. I rebooted the VM a few times and now it's working again and the cameras are working correctly! I think I was using the live --> streams to name the cameras something more friendly than front_door.

[hawkeye217]

to name the cameras something more friendly

You can still do that, just specify the live --> streams at the camera level, not at the global level. For example:

...

cameras:
  front_door:
    enabled: true
    ...
    live:
      streams:
        Front Door: front_door
  front_door_package:
    enabled: true
    ...
    live:
      streams:
        Package Cam: front_door_package
  ...

When you specify it at the global level, you are telling Frigate to use that configuration for all of your cameras. This is why the wrong stream was being displayed.

Thank you so much for the help!
