No camera in Mainsail, but works from Pi just fine?

Basic Information:

Printer Model: Creality Ender 3
MCU / Printerboard: BTT SKR Mini E3 -v- 3.0
Host / SBC: Raspberry Pi 4B, 2GB
klippy.log

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed

Describe your issue:

Don’t understand this… in Mainsail, all I get from the raspicam is “No signal.” However, if I directly access the RasPi4 with a keyboard and display attached directly to the card, and I enter “libcamera-hello,” I get about five seconds of video, then it cuts out and leaves the following lines:

I’m guessing I don’t have the crowsnest.conf file set up with accurate information… what’s in it now doesn’t match with the output of the RasPi from the “libcamera-hello” command. Do I need to take the information from the Pi output and plug it into the crowsnest.conf file and do a software reboot? Attaching the crowsnest.config.

Thanks in advance!!

Note: this post was previously and mistakenly placed in the “Frontends” category, and I’ve no idea how to move it (or if I even can move it), so apologies for the same topic double-post.

Please don’t multiply your threads.

For it refers to camera stuff, it belongs to frontends, in your case to Mainsail.

Apologies for the duplicate… I didn’t realize camera issues went into Front End, though in retrospect that makes sense.
