Two USB-cameras with no specific ID

[simplykami]

Hey guys :)

I was wondering if anyone has encountered a similar issue:
I currently have two instances of OctoPrint running on my Pi. I'm attempting to connect a camera without a unique product ID (both SN0001) to each printer, but I'm encountering difficulties in getting this to work :/
Is it possible to allocate separate ports on the Pi for each camera? If so, how can I configure this after deploying the two instances?
Any help would be greatly appreciated :)

Bye

run octoprint_deploy with the noserial option: https://github.com/paukstelis/octoprint_deploy/wiki/Command-line-arguments

Good morning :) This is my diagnostic output - Paco is currently not connected and only Paco's camera is connected (Egon completetly discon)

[paukstelis]

Can you verify that you just did the streamer change from the Utilities menu?
If that is the case, re-run octoprint_deploy (using noserial option) and remove the existing camera.
Then, reinstall the camera.

[simplykami]

I'll just delete all the instances again and do it all over again. But just so I've understood you correctly:

1. start deploy with noserial
2. streamer change in utilities
3. then install the instances (including camera)
4. setting up the cameras with option "0" ustreamer
5. Tadaa! It should work?

[paukstelis]

It should. If you have issues, the diagnostic output will help resolve those.

[simplykami]

So here I am again, unfortunately I haven't had much time in the last few weeks. This is what happens when I try to change the streamer. Should I do a complete reinstallation now?

This allows you to change the default webcam streamer.
Please note, it DOES NOT change the streamer for existing cameras.
You will need to delete and reinstall those cameras for changes to take effect.

2) None/Skip

If I now try to install another instance directly with camera and ustreamer, I get these messages
