Can't get 2x2 - 1 camera always fails

[geeklingo]

Just installed the latest v3 build, fairly simple setup using the 2x2 grid. One camera always fails to load though, all the streams are fine (confirmed via VLC) and if i move the camera order around it works but another fails. That said i notice that the ones that won't run together are the same model (Dahua PC-T5442TM-AS). The other 2 Dahua's stream fine together (IPC-HDBW4421E). I think H.265 might be the difference with the new ones (ones that fail).

dispay1.yml:

essentials:
  #Rpisurv will rotate over the following screens in the order they are configured here, if you only define one screen no rotation will happen

  #If you enable this option no auto rotation will happen, but you will still be able to select a screen by pressing and holding a Function Key (F1-F12) or numpad keys
  #Defaults to False
  #disable_autorotation: False

  screens:
    - camera_streams:
        - url: "rtsp://user:pwd@192.168.100.1:554/cam/realmonitor?channel=1&subtype=1"

Some things to try

• Can the NVR handle so many simultaneous streams?
• What if you lower the resolutions
• What if you change codec to standard H 264

[geeklingo]

Hi, will check the other 2 points but the first is that NVR is pi 4.

any update?
