New install RPi - `'zmc -m 1' exits abnormally when camera defined

[scheen]

Hi All

I'm new the ZM...

Installed for the first time ZM 1.36 on RPi 4b 8GB with 480GB SSD according to the latest Debian guide https://wiki.zoneminder.com/Debian_10_B ... om_ZM_Repo
Install worked fine.

I have one camera (TP-Link Tapo TC70). I can stream with ffmpeg on the CMDL with `ffmpeg -i "rtsp://user:pass@192.168.xxx.xxx:554/stream1" out.mp4` without problems.

However, in ZM, when I add the camera in the Console as an FFMPEG device, leaving everything empty expect for the Source path to `rtsp://user:pass@192.168.xxx.xxx:554/stream1` and setting resolution to 1920x1080, then

I get an error in the logs `'zmc -m 1' exited abnormally, exit status 255`. ZM is also not able to stream from the camera.

How can I debug this further, to understand what is going on? Or maybe someone has the cure to this right away?

Many thanks

RPI may not be able to do 1920x1080. Try lowering the resolution / framerate.

It's not just recording a video, it's also trying to do motion detection (mathematical analysis of the stream) which
requires a powerful CPU.

Thank you for the suggestion.

I changed it to 640x360 and monitor only.

Sadly, that still fails - however with a different error message:
'zmc -m 2' exited abnormally, exit status 255

What else can I do to get more useful error output?

Turn on debug logs. Options->Logging->ZM_DEBUG.
