'/dev/video0/' : no such file or directory

Digitalis Digitalis

Hello, I am currently working on a project with Omega2+, and I need to take a video. Since I did not found anything to take a video, I was thinking about taking a lot of images and make a video with it.

But I have a problem when I try to use fswebcam. I followed the steps on this guide: https://docs.onion.io/omega2-project-book-vol1/timelapse-camera.html so I assume that the installation is correct. But when I try to use a fswebcam command, I got this error:

Opening /dev/video0 . . .
stat: No such file or directory

I am using this webcam: https://www.logitech.com/en-us/product/hd-webcam-c270?crid=34

I really don't understand why I got this error, maybe the webcam is incompatible?

Thanks for your response!

Do you see in the kernel log that the device is recognized when you plug it in? dmesg to print the log.

CAP 33

Hey. I also encountered a similar problem.
Entered the command line dmesg, there were many different lines. Among them I saw these:

uvcvideo: Found UVC 1.00 device USB 2.0 PC Cam (5149: 13d3)
input: USB 2.0 PC Cam as /devices/platform/101c0000.ehci/usb1/1-1/1-1:1.0/input/input0

I understand that Omega sees my camera.
PS
Previously, everything was fine, but now error occurs:

Trying source module v4l2...
/dev/video0 opened.
No input was specified, using the first.
Error selecting input 0
VIDIOC_S_INPUT: Resource busy

Hello @Maximilian-Gerhardt , thanks for your response! I did the command dmesg, and I read the whole log, and I didn't have

uvcvideo: Found UVC 1.00 device USB 2.0 PC Cam (5149: 13d3)
input: USB 2.0 PC Cam as /devices/platform/101c0000.ehci/usb1/1-1/1-1:1.0/input/input0

like @CAP-33 (or something similar). So I assume that my webcam is not detected by the system, it was probably the problem! So I will take another. Thank you again
