Describe the problem you are having

Is this (reported by neolink log) anything that can be fixed on the frigett end ?

Then its sort of the same stuff repeated over and over.

The buffer full messages from neolink are not directly fixable from Frigate's end - they indicate that neolink is producing frames faster than Frigate can consume them(1). However, there are several configuration adjustments you can make to address the ffmpeg connection issues:

For Reolink cameras, the documentation recommends using specific input arguments(1). You should modify your configuration to use UDP instead of the generic RTSP preset:

ffmpeg:
  inputs:
    - path: rtsp://10.10.10.9:8554/kitchen/Sub
      input_args: preset-rtsp-udp
      roles:
        - detect
        - record

(1)

The errors show "Operation not permitted" and "Invalid data found when processing input", which suggest connection stability issues(1). Since you're using neolink as an intermediary, you might also try:

1. Reducing the detect fps from 6 to a lower value like 3 or 4 to reduce the frame consumption rate
2. Using go2rtc as a restream buffer between neolink and Frigate(2):

go2rtc:
  streams:
    kitchen_cam:
      - rtsp://10.10.10.9:8554/kitchen/Sub

cameras:
  Kitchen-Cam:
    ffmpeg:
      inputs:
        - path: rtsp://127.0.0.1:8554/kitchen_cam
          input_args: preset-rtsp-restream
          roles:
            - detect
            - record

(2)

The high bandwidth warning (25414.79 MB/hr) also suggests the stream may have quality issues that could be contributing to the connection problems(3).

Thanks autobot - this is what fixed it - no other changes needed. And I was about to replace the cam with a native rtsp one.
