My device is a Inspiron14 running ubuntu 20.04.

A run of ls /dev/video* gives me video0 and video1

I tried using ffmpeg -f v4l2 -video_size 1280x720 -i /dev/video0 -frames 1 out.jpg  to take a photo, the light did lit up but no photo was generated. And there are nothing covering the camera. So it is likely a software issue. What should I do now?

 

(People from Inspiron board told me to ask here.
