Libcam octopi Arducam 16MP autofocus, following the instructions

Raspberry Pi Cameras libcamera
1

Looking for ideas - I have followed the guide to the letter, no updates, but something is still missing. The libcamera takes a still photo, but OctoPrint doesn’t show the stream. Any help is welcome!

Test step:

libcamera-still -t 5000 -o test.jpg -n

The image is created, also verified through SFTP.

After launching OctoPrinter the stream at http://octopi.local/webcam/?action=stream doesn’t show.

### Windows users: To edit this file use Notepad++, VSCode, Atom or SublimeText.
### Do not use Notepad or WordPad.

### MacOSX users: If you use Textedit to edit this file make sure to use 
### "plain text format" and "disable smart quotes" in "Textedit > Preferences"

### Configure which camera to use
#
# Available options are:
# - auto: tries first usb webcam, if that's not available tries raspi cam
# - usb: only tries usb webcam
# - raspi: only tries raspi cam
#
# Defaults to auto
#
#camera="auto"

### Additional options to supply to MJPG Streamer for the USB camera
#
# See https://faq.octoprint.org/mjpg-streamer-config for available options
#
# Defaults to a resolution of 640x480 px and a framerate of 10 fps
#
#camera_usb_options="-r 640x480 -f 10"

### Additional webcam devices known to cause problems with -f
#
# Apparently there a some devices out there that with the current 
# mjpg_streamer release do not support the -f parameter (for specifying 
# the capturing framerate) and will just refuse to output an image if it 
# is supplied.
#
# The webcam daemon will detect those devices by their USB Vendor and Product
# ID and remove the -f parameter from the options provided to mjpg_streamer.
#
# By default, this is done for the following devices:
#   Logitech C170 (046d:082b)
#   GEMBIRD (1908:2310)
#   Genius F100 (0458:708c)
#   Cubeternet GL-UPC822 UVC WebCam (1e4e:0102)
#
# Using the following option it is possible to add additional devices. If
# your webcam happens to show above symptoms, try determining your cam's
# vendor and product id via lsusb, activating the line below by removing # and 
# adding it, e.g. for two broken cameras "aabb:ccdd" and "aabb:eeff"
#
#   additional_brokenfps_usb_devices=("aabb:ccdd" "aabb:eeff")
#
# If this fixes your problem, please report it back so we can include the device
# out of the box: https://github.com/guysoft/OctoPi/issues
#
#additional_brokenfps_usb_devices=()

### Additional options to supply to MJPG Streamer for the RasPi Cam
#
# See https://faq.octoprint.org/mjpg-streamer-config for available options.
#
# NOTE: Newer raspi cam modules are reporting as usb devices causing these
#       options to be ignored. Set `camera="raspi"` to avoid these issues.
#
# Defaults to 10fps
#
#camera_raspi_options="-fps 10"

### Configuration of camera HTTP output
#
# Usually you should NOT need to change this at all! Only touch if you
# know what you are doing and what the parameters mean.
#
# Below settings are used in the mjpg-streamer call like this:
#
#   -o "output_http.so -w $camera_http_webroot $camera_http_options"
#
# Current working directory is the mjpg-streamer base directory.
#
camera_http_webroot="./www"
camera_http_options=""

# Configuration of network monitoring
#
# This enables network monitoring for wifi connections with a simple ping test.
# If connection terminates by variable reasons system tries to restart the wifi connection to reestablish a connection.
# The connection test is done every minute.
# By default it is disabled (0 = off / 1 = on)
# dstination_host can be an ip address or a hostname (for hostname ensure dns resosultion is working correctly)
enable_network_monitor=0
destination_host=192.168.1.1

### EXPERIMENTAL
# Support for different streamer types.
#
# Available options:
#   mjpeg [default] - stable MJPG-streamer
#   hls - experimental FFMPEG HLS streamer
#camera_streamer=mjpeg
camera="libcamera"
camera_libcamera_options="-r 1280x720 -f 15"

Your service did not start correctly.

Hold on a second, I’ll give you a command to verify.

@kanapala

Please use the following command:

systemctl status webcamd.service

Please send me the output information to look at.

ERROR: could not find input plugin
It seems that the plugin was not installed successfully.

What steps did you follow to install this plugin.

Hey!
I followed the Guide by Wong exactly, to the best of my understanding.

Hey,
it seems that choosing english US as locale in Raspberry Pi Imager resolved the install script not working. I got the idea from the forums somewhere, different languages, different " symbols. I have it streaming in OctoPrint

Allthough the test is not working:

Your service has started successfully.
You can access the camera from another computer by opening a browser and entering the ipv4 address of your Raspberry Pi.

14

I guess I can’t run the test libcamera-still -t 5000 -o test.jpg -n while it is already busy streaming?

@kanapala

Your service has been started.Your camera is being used and you can’t call from the command line.

Please enter your Raspberry Pi ipv4 address into the browser for preview and control.
