Hello, Apologies if I am in the wrong area, however I am having trouble deciphering an error I have come across.

Host system:
Fedora 33 (uname -r) 5.11.18-200.fc33.x86_64

Zoneminder packages currently installed (these have updated as of when the error first occurred) I am using the zmrepo provided by zoneminder.com:
zoneminder-common-1.35.28-1.38.20210511gitgc080dd8a1.fc33.x86_64
zoneminder-httpd-1.35.28-1.38.20210511gitgc080dd8a1.fc33.x86_64
zoneminder-1.35.28-1.38.20210511gitgc080dd8a1.fc33.x86_64

Library version referenced in the below error (attempted downgrade, with same result listed below):
libstdc++-10.3.1-1.fc33.x86_64

Error when attempting to run zmc -m 1 manually:

Camera:
rtsp connection to an ip camera (1080P resolution), works through VLC, both on my own machine, and on the host.

This error started appearing today (May 11th 2021) after I grabbed the latest zoneminder packages this morning (around 11 AM Eastern US time).

I don't know if I've fixed this, but we went looking and found once spot that could cause a problem.

So please update and try today's build.

Sorry, seems the issue is still present in this version:

Edit:
Avoiding a double post, but I downgraded until I got a working version, apparently the change happened between these two versions:
Working:
zoneminder-common-1.35.28-1.19.20210508gitgd3e91da51.fc33.x86_64
zoneminder-httpd-1.35.28-1.19.20210508gitgd3e91da51.fc33.x86_64
zoneminder-1.35.28-1.19.20210508gitgd3e91da51.fc33.x86_64

First version with the failure I am seeing:
zoneminder-1.35.28-1.24.20210509gitg01834d4dd.fc33.x86_64.rpm
zoneminder-httpd-1.35.28-1.24.20210509gitg01834d4dd.fc33.x86_64.rpm

I have an idea what is going on based on some googling.

Do you have your ImageBufferCount set to 0? It actually needs to be somewhere around 3 to 5 (3 works for me but I've seen some choppiness in live view).

Some code assumes at least 1

Posted: **Thu May 13, 2021 1:31 pm**

Imagebuffercount is set as 3. This seems to be default, as I did not change it since i reinstalled as a test.

Posted: **Thu May 13, 2021 6:27 pm**

I think I have it figured out. New packages building now.

Posted: **Thu May 13, 2021 9:06 pm**

Installed these versions, monitors all work.
