[Config Support]: High CPU load advice

[james-barrett]

Describe the problem you are having

My 4 camera setup works, uses Coral TPU and Intel iGPU passthrough but the CPU load is 40% showing in the Frigate UI and 25% over 4 Cores in Proxmox, is this expected? seems a little higher than i was expecting.

you are restreaming both the main and sub stream, presumably based on the reolink rtsp URls you are using high res reolink cameras which restreaming is expensive. Best way to know for sure is to attach a screenshot of the system page from the UI which shows what is using CPU

[james-barrett]

yes sorry, also the htop incase it helps

[NickM-27]

Right, so go2rtc is using the most cpu. Would likely see a considerable drop if you used the sub streams for live view and didn't restream the high res

[james-barrett]

trying not to sound dim but, how to use substreams for live view :)

[NickM-27]

your config would change ot something like this

go2rtc:
  streams:
    camera1: # <- updated
      - rtsp://admin:xxx@192.168.0.181:554/h264Preview_01_sub
  log:
    exec: trace

detect:
  width: 640
  height: 360
  fps: 5

cameras:
  camera1:
    ffmpeg:
      inputs:
         - path: rtsp://admin:xxx@192.168.0.181:554/h265Preview_01_main # <- uses stream directly
           input_args: preset-rtsp-restream
           roles:
            - record
         - path: rtsp://127.0.0.1:8554/camera1?video=copy # <- updated
           input_args: preset-rtsp-restream
           roles:
            - detect

[james-barrett]

Ahh, makes sense now i see the config, Thank you so much for your help.
