v4l2 Webcam Error "Inappropriate ioctl for device"

[Bones558]

I have a Logitech C920 webcam I am trying to use on my Radxa Zero.

I'm running Armbian 23.11.1 Bookworm 6.1.63 64-bit.

 

When I run v4l2-ctl -i /dev/video1 --list-formats to query the webcam, it errors out.

 

VIDIOC_S_INPUT: failed: Inappropriate ioctl for device
ioctl: VIDIOC_ENUM_FMT
        Type: Video Capture Multiplanar

        [0]: 'NM12' (Y/UV 4:2:0 (N-C))

 

It seems anything relying on v4l2 is also failing to work.

 

Anyone have ideas of what the issue may be?

 

Thanks!

 

----------------------

 

FYI...If I use this webcam on a RaspberryPi 4 running Bookworm, it produces the following output and all v4l2 work.

Video input set to 0 (Input 1: Camera, ok)
ioctl: VIDIOC_ENUM_FMT
        Type: Video Capture

        [0]: 'YUYV' (YUYV 4:2:2)
        [1]: 'H264' (H.264, compressed)
        [2]: 'MJPG' (Motion-JPEG, compressed)

What does dmesg show when connecting the device on both the rpi and the zero?

You get anything from:
 

v4l2-ctl --list-devices

No, that does not work either.

The issue happens under "Armbian Bookworm    Minimal CLI".

 

 

Another fact I've found:

Since posting the original question, I tried "Armbian Jammy    Minimal CLI".

The camera works under Jammy.

 

So the issue seems specific to Armbian Bookworm.

(Note the camera also works under Raspberry PI's Bookworm.)
