When using the stereo camera array on bullseye, I get a few different warnings and errors

I’ve made the following changes to my /boot/config.txt

camera_auto_detect=0
dtoverlay=imx477

I’ve tried on 32 and 64 bit OS. Interestingly the image still shows. However, the buffer parsing error concerns me.

hi, @ppeetteerr

Have you installed our libcamera-dev and libcamera-apps?

You can use the following command to view version information:

dpkg -l | grep libcamera

libcamera-still --version

If the image can be displayed normally, I think these messages are basically harmless.

The message went away when i changed my configuration from Preview to Still. I believe that is because the buffer goes from 4 to 1 for the still camera settings. If you’re using the picamera2 library that should look like:

   from picamera2 import Picamera2
   camera=Picamera2()
   main = {"format": 'BGR888', "size": (camwidth, camheight)}
   raw = {"format": "SRGGB12_CSI2P", "size": (camwidth, camheight)}
   config=camera.still_configuration(main,raw=raw)
   camera.configure(config)
   camera.start()

Hi, @ppeetteerr

thanks for the solution, are you using rpi 3?
