Hello I have successfully set up Arducam 16MP AutoFocus on my OctoPi.
Using Raspbian Bullseye image and libcamera-dev + libcamera-apps 0.0.7 (because mjpg-streamer-experimental won’t compile with versions 0.0.8 and 0.0.9).
I got image and video stream, but the stream is being interrupted every 2-3 minutes. Basically the video stream “stops”. I can fix it for a next few minutes by reloading web browser (or Cura slicer window or mobile application) but after the next 2-3 minutes, video stops again.
@Edward I managed to fix my problem. I did a clean install with libcamera 0.0.9. Camera worked perfectly until I added some plugins. I manage to round it down to OctoApp integration. But it’s kind of not their fault I think.
Problem is that when taking snapshots, camera mode switches to another resolution and then back to my configured stream resolution. When plugin do this “rapidly” like every few seconds, webcamd crashes. Also FPS is kind of weird, with -f 10, the stream is much smoother than with -f 30 or -f 15.

Looks like the bug is related to the fact, that http://octopi.local/webcam/?action=snapshot takes snapshot with full camera resolution, but at the same time camera is streaming in 1080p resolution and this keeps switching camera modes and that causes out of memory error related to buffers, because buffers are not flushed fast enough to keep up.
For other cameras, like my USB camera, snapshot is taken in the same resolution as the stream is running in.
