Are there any non-YUV formats supported?
$ ffmpeg -f v4l2 -lis
It does nothing more, just a black window and no error returned on the terminal.

What does video -g -f /dev/video0 do?
(The -g flag being of interest here).
I thought that the webcam was broken but I've tested
it with a live Debian 12 usb key and it works.

Hello,
$ video -q -f /dev/video1
video: /dev/video1 has no usable YUV encodings
$ video -s 1920x1080 -f /dev/video1
video: /dev/video1 has no usable YUV encodings
thanks for your suggestion

on my thinkpad X1 Carbon 5th Gen., /dev/video0 is the infrared camera,
/dev/video1 is the one I want.
unfortunately, yes the slider is well opened and I can confirm that when it is
closed no LED will be visible.
Thanks

covers the visible light camera, anyway... not sure about the IR one.
though actually the "camera in use LED" no longer lights when that slider
is closed on mine.

A lot of the Thinkpad laptops have a physical switch that will
cover/uncover the camera. Can you switch it to the other and try again?

Hi,
$ video -f /dev/video0
video: ioctl VIDIOC_DQBUF: Invalid argument
the LED lights up near the camera and a black window is displayed...
I've strictly followed https://www.openbsd.org/faq/faq13.html#webcam
then to answer Crystal:
$ ffplay -f v4l2 -input_format yuyv422 -video_size 960x540

To be sure: you have kern.audio.record=1, right?

What happens if you run /usr/X11R6/bin/video instead of using ffmpeg?

Please post a full dmesg next time.

Hello,
I've tried to used the integrated webcam on my brand new Thinkpad T14 on
OpenBSD 7.3 without success. I've followed the FAQ.
The webcam seems well detected but no image is displayed...
This is what I get:
# uname -a
OpenBSD hyperion.my.domain 7.3 GENERIC#1072 amd64
# usbdevs -v
20 matches
