ZoneMinder Forums

Hi,

I use Zoneminder on Ubuntu 18.04 from iconnor's repo. Last day I upgraded ZM 1.36.21 to 1.36.23.
My monitors are mjpeg (axis) and some h264.

After upgrade I experienced that there is an message on Monitors:
"Monitor is not capturing. We will be unable to provide an image".

Example I find these in log:

I removed Monitors and recreate them but nothing changed the error is same.

ZM cannot display and record images from any camera.

Can someone help me?

Thanks and Regards

As per the many similar threads, update to 1.36.24.

@Magic919
Thank you for your advice. I didn't find newer update but I checked it now again and I found 1.36.24. I upgraded it now and it seems to be this version is work.

I think someone experienced same problems and iconnor made a pacth.

Thanks iconnor for quick fix.

Thanks and Regards
