Issue with netcam_high_url option

[Kobbe1]

Hi,

I am running the latest docker from ghcr.io/motioneye-project/motioneye:edge under Debian. I also have an old 0.42 direct install on an old raspi running fine (motion is 4.4.0+git20211023-2645d67).

All worked so far after a bit of tweaking. However one strange issue occurs that I can't really explain.
I added an cheap PTZ cam with rtsp://IP:554/onvif1 - works fine. (user name and pw are in the conf file ...)
On the old 0.42 all worked fine with below "extra options".

netcam_high_url rtsp://IP:554/onvif1

However when I add this on the 0.43 docker the stream just stops. Which is strange as the option should only be used when motion is detected. It works fine on other cams on the same docker.
Any ideas? Might be a motion issue after all?
