The v4l2-ctl tool is used to control video4linux devices, either video, vbi, radio or swradio, both input and output. It's obvious that cv2. As part of the program, I cange the resolution of the camera to The Logitech camera can get up to 1280x720. Is there a way to find out the max camera resolution before calling fswebcam? Because when I set my script to 1280x720 For above modes of imx185, v4l2-ctl will outputs 2 formats, (1920x1080 @30fps and 1920x1080 @30fps) I looked into the related v4l2 api in camera_common.

I would like to know its supported resolutions. Is there a way to find it out by means of software (and without having to consult Checking USB camera resolutions in Ubuntu is straightforward with the v4l2-ctl tool. - "--list So all I need is simple - a list of currently avaliable video capture devices (web cameras).
