Ffmpeg warning for one camera only

[nabheet]

I am not really sure what this warning is telling me. Is this something I can ignore? or ffmpeg input options I could/should investigate?

This means that there is corrupted data coming from your garage camera. The recordings will not be complete. You should investigate the cause by looking at the other logs.

These two events are the only things logged over and over. I don't see anything else. What should I investigate? Will ffprobe tell me anything? Could I be dropping packets as this camera is farthest from my mesh network? Can I turn on verbose mode or something?

LOL! I lied. Maybe there is more going on here?

These are latest settings I am trying:

ffmpeg:
  # input_args: preset-rtsp-restream
  input_args: >-
    -hide_banner -loglevel warning
    -avoid_negative_ts make_zero -fflags
    +genpts+discardcorrupt -rtsp_transport tcp
    -timeout 5000000 -use_wallclock_as_timestamps 1
  hwaccel_args: preset-nvidia-h265

The errors with non-garage cameras seem to have stopped. But the garage camera is still reporting those warnings. I dont see any other errors and there doesnt seem to be any packet loss.

These are common errors for a wifi camera with a spotty connection.

ah - I can investigate the connection. Thank you!
