I have a generic USB endoscope that I use as a nozzle cam as well as an Arducam with automatic nightvision for a bed monitoring camera - plugged in to the PiCam header on a Raspberry Pi 3B+. These both worked fine under Crowsnest 3.0 (albeit at a low frame rate). Even the night vision turned on automatically. I took the upgrade to Crowsnest 4.0 and I now see "errored: null" displayed for both cameras.
I ran an uninstall on V3 before upgrading to V4. I added the camera settings from my old crowsnest.conf file to the new conf and updated the mode for each to "camera-streamer". I also updated the settings in Mainsail to "Camera Streamer" and "webcam/webrtc" for both cams. No luck. Next, I verified that legacy support was still set to no in raspi-config and edited the /boot/config.txt file to include the "dtoverlay=ov5647" to the "[All]" section thinking that would at least get the Arducam back. No dice.
Next, I ran the libcamera-hello --list-cameras command and verified that it found both cameras and verified the device identifier for both is the same in the crowsnest.conf file. Rebooted several times - still no dice.
Latest crowsnest.conf and Crowsnest log entry attached to post.
Any thoughts or tips are greatly appreciated! TIA.
