The "Broken pipe" error indicates that ffmpeg is crashing or the connection to your camera streams is failing. Based on the error logs and your configuration, here are several issues to address:

1. Camera Stream Configuration Issue

You're using preset-rtsp-restream as your input args(1), but you're connecting to go2rtc restreams. This preset is designed for direct camera connections, not restreams from go2rtc.

For go2rtc restreams, you should use preset-rtsp-generic instead(1):

ffmpeg:
  input_args: preset-rtsp-generic

(1)

2. Missing Camera in go2rtc

Your config references a camera 5_ano in the camera configuration, but in go2rtc streams it's defined as 5a_ano. This mismatch will cause connection failures.

3. Retry Interval

You have retry_interval commented out. When ffmpeg crashes, Frigate waits before retrying. The default is 10 seconds(2). You may want to enable this:

ffmpeg:
  retry_interval: 10

(2)

4. Hardware Acceleration

You have hwaccel_args: auto commented out. With 14 cameras recording continuously, hardware acceleration would significantly reduce CPU load(2):

ffmpeg:
  hwaccel_args: auto

(2)

5. Recommended Configuration Changes

Here's what your ffmpeg section should look like:

ffmpeg:
  path: default
  global_args: -hide_banner -loglevel warning -threads 2
  hwaccel_args: auto
  input_args: preset-rtsp-generic
  retry_interval: 10
  apple_compatibility: false

(1), (2)

And fix the camera name mismatch in go2rtc:

go2rtc:
  streams:
    5_ano: rtsp://admin:[email protected]/Streaming/Channels/101

After making these changes, restart Frigate to apply the new configuration.

after insert this configuration, after few minutes recive the same error.
Another suggestion ?

[hawkeye217]

The logs are indicative of resource utilization issues.

You should set logging back to the default to make sure you are not missing anything critical.

logger:
  default: info

Also, you should define a low-resolution stream with the detect role. This will dramatically reduce resource usage. See the note in the official docs: https://docs.frigate.video/configuration/cameras/#setting-up-camera-inputs

Finally, you should set up hardware acceleration by using a hwaccel_args preset: https://docs.frigate.video/configuration/hardware_acceleration_video

I'm already using AMD GPU acceleration, I'll increase the log level to see if I can get more information... thanks!
