Amcrest cameras not working under Ubuntu Noble 24.04

[montreal73]

Hi, I was running a mix of Reolink and Amcrest cameras in Zoneminder 1.36.33 and Ubuntu 20.04.4 LTS.

I have a replacement computer and have installed Ubuntu 24.04 Noble release. I installed using the same method as listed here: viewtopic.php?t=33210

Zoneminder is running (version 1.36.34) and the Reolink cameras come up fine. The two Amcrest cameras : IP8M-MB2546EW and IP8M-249EB-28MM do not show. I am using the same settings that worked before:

Ffmpeg
Monitor
rtsp://cameraname:password@IP:554/cam/realmonitor?channel=1&&subtype=0
TCP
allowed_media_types=video
32 bit color
3840 2160 on IP8M-MB2546EW and 2560 1440 on IP8M-249EB-28MM

The cameras are set to send 2 frames per second.

Log says:

7/2/24, 1:57:35 PM EDT zmc_m9 6109 ERR Failed to prime capture of initial monitor zmc.cpp 258
7/2/24, 1:57:35 PM EDT zmc_m9 6109 ERR Unable to open input rtsp://(IP):554/cam/realmonitor?channel1&subtype=0 due to: Server returned 404 Not Found zm_ffmpeg_camera.cpp 325
7/2/24, 1:57:35 PM EDT zmc_m3 6095 ERR Failed to prime capture of initial monitor zmc.cpp 258

Any suggestions?

I've found it is best to use ONVIF and let Zoneminder detect the Amcrest cam settings.

Here is the string from one of my cams:

rtsp://user:password@192.168.50.9:554/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif

Make sure you have the resolution set right in Zoneminder to match the camera. Also use TCP not UDP. You can use more than 2 FPS...try 10 FPS.

Yeah the channel in the url is missing the =

Thank you! I had forgotten the = sign in every camera. They are up now.
Now I will work on optimizing the settings.
