Is it possible to use crowsnest to host lan accessible cameras without mainsail?
Basically I'm wanting to be able to get the crowsnest camera feed/feeds into LightBurn software for my laser cutters. I know that might be a stretch so how about camera feeds over Lan into OBS Studio for Recording/Streaming. Which only requires a url to connect to. From there it can be viewed or turned into a virtual camera which can be detected/accessed in LightBurn ( few hoops to jump through, but can work )
Getting camera feed into LightBurn if not directly plugged into the device running the software is a huge issue lately, and a lot of people ( myself included ) have our computer somewhere else that is climate controlled and our laser in non climate controlled area of the building. So being able to use crowsnest as a bridge would be a god send.

if i have to run Klipper on the Pi and mainsail/fluid that's fine, but would ultimately want to be able to at least get the camera feed urls to view in OBS Studio.

Thanks
Destro

P.S> i'm not a dev/linux master, but can get the job done as long as no one assumes i m a full stack developer and jumps over steps...

I am not sure if I understand that correctly, what do you mean by "lan accesible cameras" ? Something like IP cams with an inbuilt interface?
If you put for ex a Pi Zero with an Raspicam V2 attached camera next to your Lasercutter then it is easily possible to reuse its stream.
Basicly crowsnest is designed to stream videofeed from cameras they are attached to the host (PI, other SBCs / x86 machines). Something like proxying IP Cameras to elsewhere is not possible.

tldr: Need to know if i can get the crowsnest camera feeds source as a url to view sans Mainsail interface so OBS Studio can hook in and turn into a virtual webcam on my workstation

Local Area Network only. Zero interface, just the camera feed.

I'm needing to get the Crowsnest camera feed into my workstation approximately 300 feet away, minus the mainsail interface. OBS Studio can hook into it if it has a local url, and turn that feed into a virtual webcam. At that point the OS sees it as a direct webcam feed and then LightBurn can hook into that and gain it's full functionality.

As i stated am not opposed to setting up a full Klipper/Mainsail/Crowsnest, just need to know if it's possible and how to grab the camera/cameras feed in a url form, so that i can view just the camera feeds on the workstation.

Currently i can use my phone and DriodCam on the workstation, but that means i have to leave my expensive iPhone on the laser in the shed in the back yard. not really worried about theft, more that I am out of contact while doing so. Would just be nicer to have a webcam and RPi permanently set up on the laser like i do for my 3D printers, also Mainsail/Crowsnest allows for multiple camera feeds. which would allow me to also view the lasers cooling fluid temps live
Enclosed image shows the Droidcam feed and how LightBurn places that feed in the background.
I was using VDO.ninja, but that requires the feed be uploaded to their servers and then downloaded 2X the isp data consumption. Where as i understand that Mainsail/Crowsnest can be 100% Lan ( but also viewed off the Lan ) though would have zero need for that except maybe as a security function🤔

Basicly it is a simple http mjpg stream

nice

#

so it does have a url like Localklipperrpi.mjpg.stream ?

#

where can i find that url in the config

It is simple

#

If you dont use mainsail with klipper and such you need to configure usage without a proxy

#

Use no_proxy: true for that

#

Then your URL is http://camerasbcip:port/stream

#

So i can flash RPiOS and then install Mainsail and then crowsnest. add no_proxy: true

then once running input http:/camerasbcip:port/stream port being the port crowsnest is using and stream the name of the camera?

You dont need mainsail if you want to run only crowsnest

#

If you need the whole klipper stack you can use mainsailOS

OH! OK So just install crowsnest on any linux based system.

LightBurn has a linux bases Lightburn Bridge that uses RPi to make the laser wireless. I will also try on there after i get RPiOS crowsnest running.

Thank you very very much

Should work with ease then, I developed it on a pure RPIOs image 🙂
