What happened

crowsnet can't detect the camera csi

What did you expect to happen

that the camera is working.

How to reproduce

none it's the basic installation

Additional information

I have a raspberry pi 4+raspberry pi camera csi with raspbian lite 32bits bullsey full upgrade with user: sevensam and not pi
I use mainsail install from kiauh, same for crowsnest
When I try to put the camera on mainsail, it finds nothing.
I went to the logs and it says this: (basic settings installation)
INFO: Detect available Devices
[07/25/23 00:44:53] crowsnest: ERROR: No usable Devices Found. Stopping crowdsnest.
I tried port 8081 etc.. but if it can't find /dev/video0 it will be complicated I also tried to put direct from /dev/v4l/by-patch/***** (I tried everything) nothing works.

I ended up installing ustreamer from apt and I ran the following command line: sevensam@voron350:/dev $ ustreamer --device=/dev/video0 --host=192.168.1.20 --port=8083
and I can access the page to see the snaps or the camera stream and it works, I can even put it in mainsail (but it bugs)
then I cut CTRL+C and I only launched userstream and I started crowsnet and it worked only once, then nothing, impossible to recognize /dev/video0

ok i found

solutions for Raspberry pi Camera V2

disable camera in raspi-config (Interface - Legacy Camera : disable)
edit : /boot/config.txt
add under [all] : dtoverlay=imx219

Nota : imx219 = Raspberry pi camera v2

reboot : sudo reboot
When restarting, type the command: libcamera-hello --list-cameras
result in my case :
0 : imx219 [3280x2464] (/base/soc/i2c0mux/i2c@1/imx219@10)
Modes: 'SBGGR10_CSI2P' : 640x480 [30.00 fps - (0, 0)/0x0 crop]
1640x1232 [30.00 fps - (0, 0)/0x0 crop]
1920x1080 [30.00 fps - (0, 0)/0x0 crop]
3280x2464 [30.00 fps - (0, 0)/0x0 crop]
'SBGGR8' : 640x480 [30.00 fps - (0, 0)/0x0 crop]
1640x1232 [30.00 fps - (0, 0)/0x0 crop]
1920x1080 [30.00 fps - (0, 0)/0x0 crop]
3280x2464 [30.00 fps - (0, 0)/0x0 crop]

take the line between brackets ( ) in my case : /base/soc/i2c0mux/i2c@1/imx219@10

edit crowsnest.conf change mode and device :

mode: camera-streamer
device: /base/soc/i2c0mux/i2c@1/imx219@10

and add your camera on mainsail

PS : I found it all by myself here and there on the internet, but I just found it on the mainsail site https://crowsnest.mainsail.xyz/faq/how-to-setup-a-raspicam , but it's weird that I had trouble finding this info

Well that's solved for me.

@blondsign as @seven-sam already correct stated you can find the setup informations inside the crowsnest documentation. The needed /boot/config.txt changes can be found inside the troubleshooting section. If you can't get it work, please join the Mainsail Discord and open a post inside the support-forum.
