❗ Please note

This image needs to be flashed to your SD card, wiping it in the process. So if you want to keep anything on there, make a backup first! You can also create an OctoPrint backup, download that, flash, restore from backup. There's no way to update to the contents of this image without a full reflash.

Please provide feedback on your experience with this image in this ticket, whether things work for you or not. Make sure to at least include the following:

• Everything working?
• Pi model
• used cameras
• in case of issues: related logs (journalctl -u camera-streamer\* | pb and share the generated paste.octoprint.org URL)

Known issues:

• Stale Streams detected but not fixed ayufan/camera-streamer#94 (this is currently considered a blocker for general roll-out of this camera stack, as it causes the camera stream to crash)

Common pitfalls:

• RPiV3 camera not auto-focusing? Make sure any kind of case you've added to it is not interfering with the lens & sensor

Verification

• I'm a maintainer or collaborator of OctoPrint and allowed to use this issue type

Reflashed my RPi 4B with an RPi Camera V3 from OctoPi 1.0.0 cam, OctoPrint 1.11.3 to the new image. During the restore of the backup image, it got stuck at:

I will reboot and see what else I can capture.

I hit refresh on the browser (Firefox 143.0.1 (64-bit)) and it came back. It wanted to update the TP-Link plugin so I let it do that and it appears to be working now.

I noticed this today on an unrelated restore on a regular 1.1.0 image myself. The server came back up but the UI didn't notice and required a manual reload.

Have already added a personal to-do for myself to look at what's up there.

The RPi Camera V3 is also working. I don't have a real printer attached to this RPi so I can only print to the virtual printer.

Just in case there's anything useful in it...

Flashed the image, restored from backup.

• After enabling I2C and SPI via raspi-config, plugin WS281x LED Status is working.
• Raspberry Pi 4 Model B Rev 1.1, 4GB
• Prusa MK4S
• Printer connection works, moving the axes works
• Printing works
• RPi Camera V3 is working, AF is working, MJPEG stream is working, WebRTC stream is not working, but that did not work on the previous version as well

Everything seems to be working for me, although I just switched away from the pi-camv3 (hated that cable) and moved to a logi c270. Let me know if you need me to test with the pi-camv3 and I certainly can hook it back up.

Flashed, restored backup, up and running.

I have a camv3 connected to one of the Pis on my testrig anyhow and that works, so all good :) (Side note: hate the cable as well, hence my production cams are C270 as well ^^)

Once thing that would be interesting to know, as I haven't yet had gotten around to testing it myself: Does ayufan/camera-streamer#94 still happen?

To test:

• Reboot the pi (should have a confirmed working camera)
• Do NOT access the webcam in any way (so best close any and all tabs in your browser where it might be open)
• wait 60min
• try to access the webcam - does it still work?

[b-morgan]

I installed yesterday and verified that the RPi V3 Camera was working...

I just checked the Control Tab today and the camera is still working. The browser was not connected overnight.

Any other tests you like me to try?

[foosel]

It's important that the webcam never gets accessed for an hour after server start for the bug to trigger (if it triggers). So if you accessed it yesterday and just left it overnight without rebooting, that sadly neither confirms nor denies whether the issue still persists. A test of that would be lovely.

[foosel]

Heh, I just remembered though that I had flashed a test image earlier, like several hours ago, and only accessed that through SSH, webcam never accessed. Still works, so maybe that bug has been fixed too or at least is now less likely to trigger? If so that would only leave the very unstable libcamera situation.
