Here is the output but I am pretty sure > that this come from the integrated laptop camera and not the one in the > external monitor Well, you can use "-d" parameter to identify the device, like: $ v4l2-ctl -d /dev/v4l/by-path/pci-0000\:00\:14.0-usb-0\:3.2\:1.0-video-index0 --all The real path depends on your camera - you can take a look at: $ tree /dev/v4l/ /dev/v4l/ ├── by-id │ ├── usb-046d_HD_Pro_Webcam_C920_55DA1CCF-video-index0 -> ../../video0 │ └── usb-046d_HD_Pro_Webcam_C920_55DA1CCF-video-index1 -> ../../video1 └── by-path ├── pci-0000:00:14.0-usb-0:3.2:1.0-video-index0 -> ../../video0 └── pci-0000:00:14.0-usb-0:3.2:1.0-video-index1 -> ../../video1 In order to check the ones that were detected.
