Rotate camera rtsp stream using Frigate

Configuration
1

Dear community,

I use avigilon cameras in the HA frigate integration. Unfortunately avigilon doesn’t support rotation of the rtsp stream. And I couldn’t find out how to rotate the image for the H5 dome cam in frigate using yaml code.

Does anyone know how to do that?


cameras:
  camera1:
    ffmpeg:
      inputs:
        - path: rtsp://USERNAME:[email protected]/defaultPrimary?streamType=u
          roles:
            - detect

    detect:
      enabled: True # <---- disable detection until you have a working camera feed
      width: 1280 # <---- update for your camera's resolution
      height: 720 # <---- update for your camera's resolution

    objects:
      track:
        - car
        - person

it is recommended to use go2rtc config for the rotation and then access the stream in frigate

Hi!

that really doesnt work at all. There must be something I dont see…

go2rtc:
  streams:
    rtsp_wintergarten: 
      - rtsp://USER:[email protected]/defaultPrimary?streamType=u
      - "ffmpeg:Cam_Wintergarten#video=h264#rotate=180"

cameras:
  Cam_Wintergarten:
    ffmpeg:
      inputs:
        - path: rtsp://127.0.0.1:8554/rtsp_wintergarten
          input_args: preset-rtsp-restream
          roles:
            - detect

    detect:
      enabled: True 
      width: 1280 
      height: 720 

    objects:
      track:
        - car
        - person
        
    record:
      enabled: False
    snapshots:
      enabled: True

any mistakes in my code?

The stream is working! But the rotation still doesnt work.

Number of mistakes:

  1. The ffmpeg stream is not referencing a stream that exists
  2. You need a separate stream named something else to reference directly

ok - you mean like that?

go2rtc:
  streams:
    rtsp_wintergarten: 
      - rtsp://USER:[email protected]/defaultPrimary?streamType=u
	  
    rtsp_wintergarten_rotated:
      - "ffmpeg:rtsp_wintergarten#video=h264#rotate=180"

cameras:
  Cam_Wintergarten_rotated:
    ffmpeg:
      inputs:
        - path: rtsp://127.0.0.1:8554/rtsp_wintergarten_rotated
          input_args: preset-rtsp-restream
          roles:
            - detect

    detect:
      enabled: True 
      width: 1280 
      height: 720 

  Cam_Wintergarten:
    ffmpeg:
      inputs:
        - path: rtsp://127.0.0.1:8554/rtsp_wintergarten
          input_args: preset-rtsp-restream
          roles:
            - detect

    detect:
      enabled: True 
      width: 1280 
      height: 720 

    objects:
      track:
        - car
        - person
        
    record:
      enabled: False
    snapshots:
      enabled: True

If not - please could you correct the syntax for me? :slight_smile:
I’ve tried so many things that I dont know anymore what I’ve changed each try

You need to make the names match between go2rtc and cameras config

well - I will rotate the lens on my cam. MUCH more easier and it will work for sure :slight_smile:

For anyone else happening by: I can confirm the above works. Helped me out to achieve the same thing to cover an alley way. You shouldn’t have given up!

Thanks to all.

@Dilligaf I am somewhat confused still

This is what I have:

go2rtc:
  streams:
    entrada:
      - rtsp://user:[email protected]/live
      - "ffmpeg:entrada#audio=opus"
    
    Entrada_Rotated:
      - "ffmpeg:entrada#video=h264#rotate=90"

  webrtc:
    candidates:
      - 10.69.69.72:8555
      - stun:8555

Then for the camera settings I have:

cameras:
  entrada:
    ffmpeg:
      inputs:
        - path: rtsp://user:[email protected]/live
          roles:
            - detect

    live:
      stream_name: Entrada_Rotated 
  
    detect:
      width: 1080 # <---- update for your camera's resolution
      height: 1920 # <---- update for your camera's resolution
      fps: 7

    objects:
      track:
        - person
        - dog
        - cat

In frigate, when I view all cams, the entrada cam shows horizontal. When I click on it to view it live via frigate I do see it vertical. But pretty much that is the only place I see it vertical. Recordings are horizontal, and in HA cam view I also see it horizontal.

The example you give :

Cam_Wintergarten_rotated:
    ffmpeg:
      inputs:
        - path: rtsp://127.0.0.1:8554/rtsp_wintergarten_rotated
          input_args: preset-rtsp-restream
          roles:
            - detect

Does that mean I should create a new camera like this:

Entrada_Rotated:
    ffmpeg:
      inputs:
        - path: rtsp://user:[email protected]/Entrada_Rotated
          roles:
            - detect

The 10.69.69.12 is the cameras IP, and it doesn’t have a rotated stream, so why would the Entrada_Rotated feed be tied to the cameras IP?

10

So I was on the right track, it wouldn’t make sense to get the rotated feed from the cameras IP, but turns out the 127.0.0.1 IS NOT A CAMERA IP. Assuming it is the local host IP, and I am picking up the rotated stream I created under go2rtc config.

This is the code I ended up with:

  Entrada_Rotated:
    ffmpeg:
      inputs:
        - path: rtsp://127.0.0.1:8554/Entrada_Rotated
          roles:
            - detect

And if it was a magic trick, I finally have vertical camera!

Seems a thread on the frigate github might be confusing many people, as it makes it seem you change the live view of the existing camera.
