Zoneminder 1.36 slow on old Cameras (Mobotix D12)

[Uyunifier]

Hi,
ive added a Mobotix D12D to my new Zoneminder instance.
Unfortionally the live view takes long time until it got loaded (> 40sec).
in 1.32.3 it works smooth and instantly pops up. I already seen that there have some values changed like image buffers. Also played arround with them to find better working ones maybe. but still no change. Ive set this up via ppa on ubuntu 22.04.

How can i set it up, so that live view works almost instantly like before? Hope someone can help please.

No idea why it would take that long. Thing to do would be to turn on debug logging and see what the logs say.

If it were me I would try the mjpeg urls listed at https://www.ispyconnect.com/camera/mobotix with the ffmpeg monitor type. Should better utilise the camera.

already tried the urls. None of them (except the image ones) load fast. So they would be the only chance.
added a debug log. maybe you can find out more than. Would be awesome. thx much.

zm_debug.log

Well... those logs show it getting two successful captures in under 1sec.

Going to need more logs.

what exactly do i need to log for you? So i can do it.

if it takes 40s to get a stream, then I need 40s of logs... what is it doing after the initial 2 captures?

tried to start logging on debug now-> loaded live view page and waited until i got a picture
-> stopped logging.

zm_debug.log
