ZM stopped displaying RTSP camera

[greyduk]

Hello,
I've read through as many forum posts as I can to try and solve this problem, but I cant seem to find anything that works.

Zoneminder had been working perfectly for several months, until the 25th of February. I was away, so I didn't take the time to troubleshoot it (zm is a backup for me for now because I have Unifi Protect for all my current cameras)

I noticed it hasn't recorded any events since that date, and can't display the camera even the probe or any other place. No thumbnails in the zone editor. The rtsp provided by unifi works in VLC. The resolution I get in VLC after actually loading the stream matches the setting in zm

the ZM /dev/shm is sitting at 100% whenever I have my one camera actually enabled. When I disable it, it goes to 0%. Re-enable - immediately back to 100%.

I've checked the zm/cgi-bin/nph-zms paths are correct, and they seem to be.

Here is the log of the errors I get:

I don't know what changed on February 25th, but I do know I updated the docker install sometime around then. I can't prove they're related, but it seems like the logical conclusion.

None of us know what changed. I'd guess that ZM can no longer reach the camera.

zmc crashing is not good.

/dev/shm being 100% is likely the cause of crash.

Reduce imagebuffercount. Increase /dev/shm.

Thank you.

The problem was I needed to change the video writer from camera passthrough to encoder. Camera passthrough worked originally, but the docker update must have changed something.
