Hi, I cant get the imx477 camera to work on kstars. The camera is connected via CSI on Jetson (not rpi). The camera is identified correctly and connected, but when trying to preview I get this error...

org.kde.kstars.indi: V4L2 CCD : "[ERROR] Invalid source buffer size, skipping frame... "

and if ccd is disabled and then re-enabled, we get these log messages ..

org.kde.kstars.ekos: "V4L2 CCD is disconnected."
org.kde.kstars.indi: V4L2 CCD : "[INFO] V4L2 CCD is online. "

The imx477 camera produces perfect image when accessing camera directly using gstreamer

If I replace imx477 with a generic UVC (v4l2) usb camera, kstars works OK and shows preview.

Is this a bug, or a settings issue ?

Can anyone help me to configure kstars for the imx477 camera to work in kstars as I dont know what else to try.
