[Question]: Meaning of error "start from CONN state" and "RTSP wrong input"

What is your question:

Hey,

I'm seeing quite a few errors in my logs and I'm uncertain what they mean. Here is a snippet of them:

It looks like three cameras in total are reporting the issue. Might be more, the log of errors is pretty long.

[NickM-27]

the connection to the camera is timing out often

[Lockie85]

Ar ok, I'm going to guess this is because they are on WiFi. But if that is so it does surprise me. The WiFi mesh around my house is pretty comprehensive. Do you think there might be other reasons that could cause the time out?

[NickM-27]

the streams are sensitive, just because wifi signal is strong doesn't mean it won't drop packets or have periods of long latency that causes problems

[NickM-27]

you can try increasing the go2rtc timeout by adding #timeout=10 to the end of the rtsp url in go2rtc streams

[Lockie85]

Would this be correct for adding the timeout?

go2rtc:
  streams:
    bedroom_3:
      - "rtsp://user:password@192.168.15.56:554/stream1#timeout=10"
      - "ffmpeg:bedroom_3#audio=aac"
    bedroom_2:
    - hass:Camera-Hub-G3-E44E
    - "ffmpeg:aqara_g3#audio=aac#audio=opus"

If so, how might I also do this with the Aqara camera?
