Raspberry Pi Cameras
1

  1. Where did you get the camera module(s)?Arducam

  2. Model number of the product(s)?Arducam 64 hawkeye

  3. What hardware/platform were you working on? pi4

  4. Instructions you have followed. (link/manual/etc.)

  5. Problems you were having? Cannot view video feed in fluid or mainsail

I cannot get the cam to show up in mainsail or fluid

When I try to test the cam I get

The process that using it I believe is the mjpg stream which I hope is from fluidd using the cam and I’m just not configuring the webcam.txt file correctly.

hi, @702enigma

Since mjpg_streamer is running, it occupies the /dev/video0 node.

So your libcamera-still command fails.

From Mainsail they said this which now means I have a useless camera. Well for me anyways. Dont plan on using it for monitoring 3d prints.

Kwadfan. Good morning, after a bit of research it turns out, that these camera falls into the same categorie as the 16MP with autofocus. They use a proprietary Kernel Module. Therefor bad news. Our camera solutions will and do only provide solutions for non-proprietary Hardware or Hardware that is already part of raspberry pi os(v1/v2/hq cam modules). Also, wether crowsnest nor mjpeg-streamer using parts of raspberrys libcamera stack that is only available on bullseye images. These cameras use a proprietary video codec from bayer that has to be converted into mjpg, this creates such a big overhead that I decided not to support it with the upcomming releases of crowsnest/mainsailOS.

From technical prospectiv, more MP isnt a good deal if your network devices arent capable to deliver that huge frames. A 1080p@30fps stream could easily outperform your wifi connection. Those types of cams havent a benefit to watch a printer in my opinion.

We made libcamera plugin for mjpg-streamer. You can try to use it.

The link below has an introduction to this plugin, but it’s a demo for use on an OctoPrint system.

Alot of people are getting away from Octoprint. Mainsail and Fluidd work much better and the speeds I am printing at don’t let me use it as its lags behind the Gcode. This will not work in our use case as explained by the mainsail engineer.
