[Intel NUC7i5BNH] Another "Reduce CPU load" guy

[SHU-red]

I know that there are already many threads out there for reducing CPU load for transcoding but im an absolute noob in ffmeg, transcoding, different drivers and the hardware-combination for that

So im trying to ask for help, where i can reduce the cpu load of my Intel NUC7i5BNH
--> So its a 7th gen Intel i5

I already decreased the main streams of my two IP Cameras to h264-1280x720
But i dont see a very big impact on the CPU load

This is my current state of my config-file and i have no idea where to start
Maybe someone can give me a hint

Is it possible to correctly setup HW-Acceleration on this thing because in the docs there is a section for 'Intel QSV with h264 stream'

Thanks a lot

1. I'd suggest using preset-vaapi instead
2. are you not able to use sub streams on these cameras?
3. can you show a screenshot of the system page so we can see the different CPU usages

[SHU-red]

Thanks for your fast reply!
Below the frigate and top shown load

I fear my config file is a bit messy and im scared to screw this up
I'll try the preset-vaapi also but can you please describe in detail what i have to do? Otherwise i think i will screw this up -.-'

And btw im using Fedora CoreOS which is only a very lightweight OS

Oh, looks like your main cpu usage is because you are not using openvino, you are running detect on your CPU https://docs.frigate.video/configuration/detectors#openvino-detector

for the other one just change preset-intel-qsv-h264 to preset-vaapi

Oh Crazy!
I neves stumbled upon this

I just added

detectors:
  ov:
    type: openvino
    device: AUTO
    model:
      path: /openvino-model/ssdlite_mobilenet_v2.xml

model:
  width: 300
  height: 300
  input_tensor: nhwc
  input_pixel_format: bgr
  labelmap_path: /openvino-model/coco_91cl_bkgr.txt

And now the CPU load is drastically lower

Thank you so much!!!

Last question: I do not have to change the model widht and height to the video-stream widht and height right?

no, that is a property of the model

This is now a gamechanger for my homeserver
Thank you very much!
