Unable to make time-lapse despite working camera streams

Camera model

USB Webcam x2

What is the problem?

After a steep learning curve and much documentation re-reading (thanks for the documentation by the way :+1:) I have my 2 webcams working on OctoPi new camera stack version (Pi4 B 2GB) (but can only stream 640x480 without the camera-streamer crashing or stalling but that's another post) using the multicam plug in. However, time-lapse will not work. I get the red 'could not capture snapshots' error come up constantly, even though if I go and copy the url configured for snapshots and paste it into a fresh browser tab it shows the snapshot without any issue.

What did you already try to solve it?

Rebooting, changing resolutions in the config, restarting camera-streamer service

Have you tried running in safe mode?

No

Did running in safe mode solve the problem?

Didn't try that

Hello @CodeF1re !

At a certain point you disabled the bundled Classical Webcam plugin.

| !Classic Webcam (bundled) = /home/kieran/oprint/lib/python3.9/site-packages/octoprint/plugins/classicwebcam

Have you tried after enabling this again?

Also, the MultiCam plugin only makes sense when you more than one cam.

Yes i have 2 cameras as mentioned, one looking down at the build plate and one looking at the front for timelapse, I will try reenabling the classic webcam plugin and see if that fixes it.

Turns out it was because I disabled the classic webcam. Which I thought you were supposed to do when using the multicam plugin.

I don't believe that the 'multicam' plugin implements a timelapse handling function, so you'll have to keep the classic webcam plugin enabled to provide the timelapse, even if you don't use it for streaming.
