Bones558 Posted January 10 Share Posted January 10 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) 0 Quote Link to comment Share on other sites More sharing options...
Werner Posted January 10 Share Posted January 10 What does dmesg show when connecting the device on both the rpi and the zero? 0 Quote Link to comment Share on other sites More sharing options...

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.) 0 Quote Link to comment Share on other sites More sharing options...
