Webcam dont work!

[derTimm0]

hey,

can someone help me to configur my webcam? i testing two cams (logitech quickcam pro / wansview Webcam 1080P) both work fine out of the box on my other octopi (raspi 3+ / octoprint 1.5.3) both cams were find with "lsusb" and the cam service is naturaly startet. i tried to edit the "octopi.txt", without positiv result.

what information is required to put one of the cameras into operation?

sorry, but i'm a linux beginner ;-)

Hi, Is the webcam service started? In this distribution it should be explicitly started as by default is off.

[derTimm0]

Yes, i started it over your "scripts/citrico-config". How can i check if the service realy run? (ps -e?)

[ludiazv]

To check status of the service: systemctl status webcamd.service To view logs: journalctl -u webcamd.service

[derTimm0]

i will check it this afternoon/evening i report the result. thanks you for all ;-)

The webcam service failed. to see the log try sudo journalctl

[derTimm0]

puhhhh..... this is are much information.... Sorry but i "Verstehe nur Bahnhof" :-p

P.s. i have a OrangePI PC

log.txt

[derTimm0]

is that important information?

[ludiazv]

journalctl -u webcamd.service show only the log of the webcam.

The log shows that the service is trying in /dev/video0 and this device doesn't work. You should check to which /dev/videoX your cam is associated.

Try these commands:

ls -ltrh /dev/video*
(this should show the video devices in your system)
sudo v4l2-ctl --list-devices
(this show the properties of the devices)
sudo v4l2-ctl --device=/dev/video0 --all
(this will show details of specific device)

To configure the camera properly check this issue #8. On how to modify the configuration file /boot/octopi.txt.

does this mean that v412-ctl (is that the syntax of a program?) is not installed?

[ludiazv]

you need to install v4l-utils package using apt.

[derTimm0]

now i has install "v4l-utils" and try this

ls -ltrh /dev/video* (this should show the video devices in your system) sudo v4l2-ctl --list-devices (this show the properties of the devices) sudo v4l2-ctl --device=/dev/video0 --all (this will show details of specific device)

attached the octopi.txt with my try to reproduce this

short question: where is the problem? on my two cams or on your image/orangepi pc? i think its better to buy a raspi because my linux skill not able :-p

[catallo]

I'm using an Orange PI PC+ and I had to change MJPGStreamer to use /dev/video1 instead of the default /dev/video0 to make it work.

To do that you have to edit /boot/octopi.txt and add -d /dev/video1 to camera_usb_options. It should like like this:

camera_usb_options="-d /dev/video1 -r 1920x1080 -f 20"

.. then reboot.

that was the first thing I tested — unfortunately without success :-/

[ludiazv]

--list-devices shows /dev/video1 and /dev/video2 have you check the properpties of these devices? have you tried to take a snapshot of short video with ffmpeg? The key is to test what device is associated with your cam and with what parameters (resolution,format,...) does it work. Once you have it you need to use the camera_usb_options variable to pass the proper parameters.

[derTimm0]

it works, i switched to video 2. strange is that it still works when I switch back to video 0 or 1 XD. orangepi and i still don't become friends, and our connections are constantly lost during printing. I have already taped the 5v pin on the cable and tried it without a camera. sometimes earlier sometimes later, but not reproducible :-(

[ludiazv]

The problem with disconnects depends is not an easy problem and also happens in RPI (check octoprint forums and you will find a lot of reports on this). The best advice I can give here is:

• Power supply: Be sure yo have good power supply. Avoid power the Orange Pi from microusb. Short cable from the PSU to the Pi.
• Usb cable: Good cable as short as possible. Be sure contact is reliable. Use of ferrite bead in USB cables is also advised.
• Check the firmware of your printer. Update or donwgrade the firmware of the printer.
• Reduce the CPU speed and all you dont need (HDMI,...)

I personally run two printeres with Opis without problems. I power them from the same PSU as the printer with a buck converter via GPIOs. My usb cables are high quality about 15cm long. I had almost no issues with the printers. I run OPIZero LTS.

Best,

[derTimm0]

it can only be due to the power supply or orange pi. use the same cable (approx. 30cm) with the raspi and there are no problems. that’s no longer fun: - /
