Mainsail USB Camera Question

[Carter]

Hi, I've just decided to add a camera to my printer using Mainsail and Crowsnest, however, it shows as "No signal." 

Crowsnest config

#### crowsnest.conf
#### This is a typical default config.
#### Also used as default in mainsail / MainsailOS
#### See:
#### https://github.com/mainsail-crew/crowsnest/blob/master/README.md
#### for details to configure to your needs.

                                        # camera-streamer - Provides webrtc, mjpg and snapshots. (rpi + Raspi OS based only)

This needs to be changed to :

mode: camera-streamer

Also in your mainsail setup, ?action=stream, needs to be replaced with webrct.

See here for full explanation.

For raspi cam troubleshooting, see this section.

Hope it helps

Just tried this, it shows that is is connecting, but the webcam isnt loading. It also shows an error in crowsnest log saying,

 

[09/07/23 17:09:20] crowsnest: WATCHDOG: Lost Device: '/dev/v41/by-id/usb-GENERAL_GENERAL_-_UVC-video-index0'

Edit-Now it is displaying a grey background

Also, i went into the Webcam URL and none of the features are working, they all display "System Error" @mvdveer

is the camera to usb then must "ustreamer" activate

It is also sufficient to set the path to /dev/video0. You do not need to enter the ultra-long one.

Did you ever figure this out?

[Carter]

Yes, I found out its wasnt really compatible, I switched to a raspberry pi cam 3 and everything is working.
