Hello!
I have been trying to set up motioneye on a Raspberry Pi 4 (4 GB ram) with a Raspberry Pi HQ camera.
(Operating system: Linux raspberrypi 6.6.74+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.6.74-1+rpt1 (2025-01-27) aarch64
motionEye Version | 0.43.1b2
Motion Version | 4.7.0)

The camera has to choose one of these specific resolutions:

Modes: 'SRGGB10_CSI2P' : 1332x990 [120.05 fps - (696, 528)/2664x1980 crop]
           'SRGGB12_CSI2P' : 2028x1080 [50.03 fps - (0, 440)/4056x2160 crop]
                             2028x1520 [40.01 fps - (0, 0)/4056x3040 crop]
                             4056x3040 [10.00 fps - (0, 0)/4056x3040 crop]

And when motioneye tries to get some other resolution I get this error:

[  131.417919] unicam fe801000.csi: Wrong width or height 1088x1920 (remote pad set to 4056x3040)
[  131.417938] unicam fe801000.csi: Failed to start media pipeline: -22

The problem is that when I change the resolution in motioneye it does not change it to exactly what I wrote.
This is from the motion.log in /var/log/motioneye

[1:ml1:video0] [WRN] [VID] v4l2_pixfmt_stride: The image width(1080) is not multiple of the stride(2176)
[1:ml1:video0] [WRN] [VID] v4l2_pixfmt_stride: Image width will be padded 8 bytes
[1:ml1:video0] [WRN] [VID] v4l2_pixfmt_adj: Adjusting resolution from 1080x1920 to 1088x1920.

It adds padding to the resolution. Sometimes it seems to want a multiple of 8, other times 16 or - as in this case - the stride(2176) (whatever that means).

Since the camera only seems to output specific resolutions I have to make MotionEye accept one of those. But I can't.
I don't see any other way out of this. The camera works fine for taking photos and video with the rpicam commands (and when doing so it's fine with whatever resolution I ask for), but in motioneye I get the UNABLE TO OPEN VIDEO DEVICE error.

I would be very greatful for any help!

Just a thought, but can you edit the actual config files motioneye is generating under the hood with the proper padded resolution that you need?
