Camera service masked

[KaeShoru]

When I installed the camera everything went well up to a point. After that, the service did not work for me and the camera did not start. Can I manually create this service?

Camera was only detected as /dev/v4l/by-id entry.
This will be used as the camera device identifier
Settings can be modified after initial setup in /etc/systemd/system/cam_Ender3.service

Camera Resolution [default: 640x480]:

Selected camera resolution: 640x480
Camera Framerate (use 0 for ustreamer hardware) [default: 5]:

Selected camera framerate: 5
sed: -e expression #2, char 12: unknown option to `s'
Instance must be restarted for settings to take effect. Restart now? [y/n]: y
Failed to start cam_Ender3.service: Unit cam_Ender3.service is masked.
Failed to enable unit: Unit file /etc/systemd/system/cam_Ender3.service is masked.

Nope, i have Logitech camera too but C270

It is not clear why this is happening, but it happened to someone else on the Discord. It doesn't have anything to do with the type of camera, but with writing the service file.

You can try what they did, which fixed it:
sudo systemctl unmask cam_instancename
run octoprint_deploy, remove the camera, then reinstall the camera.

I've tried this many times and it doesn't help. Moreover, the service itself is empty for some reason (and therefore the unmask command deletes it). Is it possible to find out the approximate content of this service so that I can substitute it with my own adjustments? I also want to note that when I start searching for USB ports, the script does not show anything. Well, in addition, I want to note that I’m running all this on an Orange Pi Zero 2

[paukstelis]

I suspect it is masked because there is invalid information being supplied to the script so the service file fails.

Try installing the camera with all default values (don't change resolution or frame rate).

If it searches for cameras and doesn't show anything that means your camera is not detected as a v4l camera and won't work directly.

you can verify this:
unplug camera
sudo dmesg -C
plug camera in
sudo dmesg
provide output

The first time I installed Octoprint on this device with this script, the camera was detected correctly and worked perfectly (camera works in octoprint). But I had to redo everything a little due to the fact that Orange Pi Zero has only 1 usb port. The first time, the camera and printer were connected through the hub, but the printer kept disconnecting. Therefore, I connected the printer via gpio usb, and the camera via a regular one. It was after this that the camera stopped working.

I did some snooping and found that sed was getting confused by some double slashes appearing in one of the -e options. (Looks like it was choking on CAMPORT)

sed's pretty flexible, so swapping out / with @ as a delimiter worked fine:

However, and I've not looked into it to any degree, the CAMPORT is getting set from /dev/OCTOCAM to /dev//dev/the-actual-cam.

As a note, I'm using the latest 1.0.5 changes that fix by-id.

I have to say, this doesn't really make much sense. Not that anything is wrong, just that octoprint_deploy doesn't use mjpg_streamer at all anymore. Make changes in the mjpg-streamer section there should have absolutely no impact on it writing out the service file.

I am curious what OS this is on, because I haven't seen this with any of the versions of sed that I have used.

does this solve the problem for you? Unfortunately, I still get the same error after applying these changes....

[paukstelis]

Can you join the octoprint_deploy Discord (invite link is the README)? It is easier to help diagnose issues there.

[KaeShoru]

I ended up filling the service manually as it was done in the substitution file. Now everything works

[Blisk]

I have the same problem, the camera not working and still don't know what to do?

A camera can not work for lots of reasons. If you have an issue with a masked service file, provide the contents of octoprint_deploy/cam_instancename.attempt

OK thank you. Here it is

[paukstelis]

There is nothing wrong with that.
Re-run octoprint_deploy (sudo octoprint_deploy/octoprint_deploy.sh) and choose diagnostic info from the Utilities menu.

[Blisk]

Ok here it is. For info I have two cameras for two differend printers. none of cam works. Before I add second printer, camera works ok. Both cameras are the same.

Your issue is that ustreamer has not been installed. Choose 'Change Streamer' in Utilities menu. Remove all cameras, and reinstall them.
