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-in= dex0 --all The real path depends on your camera - you can take a look at: $ tree /dev/v4l/ /dev/v4l/ =E2=94=9C=E2=94=80=E2=94=80 by-id =E2=94=82=C2=A0=C2=A0 =E2=94=9C=E2=94=80=E2=94=80 usb-046d_HD_Pro_Webcam_C= 920_55DA1CCF-video-index0 -> ../../video0 =E2=94=82=C2=A0=C2=A0 =E2=94=94=E2=94=80=E2=94=80 usb-046d_HD_Pro_Webcam_C= 920_55DA1CCF-video-index1 -> ../../video1 =E2=94=94=E2=94=80=E2=94=80 by-path =E2=94=9C=E2=94=80=E2=94=80 pci-0000:00:14.0-usb-0:3.2:1.0-video-index= 0 -> ../../video0 =E2=94=94=E2=94=80=E2=94=80 pci-0000:00:14.0-usb-0:3.2:1.0-video-index= 1 -> ../../video1 =09 In order to check the ones that were detected.
