Unofficial snap for the cameractrls advanced Linux camera configuration command line and GUI tools.
To permit access to your webcam, the camera interface needs to be first connected:
snap connect cameractrls:camera
To permit access to out-of-spec camera options, such as HDR mode on the Kiyo Pro, connect the raw-usb interface:
snap connect cameractrls:raw-usb
From the desktop, launching cameractrls will launch the GTK GUI version.
The cameractrls.cameractrlsgtk command is the GTK GUI while cameractrls is the command line client:
$ cameractrls
usage: cameractrls [--help] [-d DEVICE] [--list] [-c CONTROLS]
optional arguments:
-h, --help show this help message and exit
-d DEVICE use DEVICE, default /dev/video0
-l, --list list the controls and values
-L, --list-devices list capture devices
-c CONTROLS set CONTROLS (eg.: hdr=on,fov=wide)
example:
cameractrls -c brightness=128,kiyo_pro_hdr=on,kiyo_pro_fov=wide
cameractrls can set the V4L2 controls and it is extendable with the non standard controls. Currently it has a Logitech extension (Led mode, led frequency, BRIO FoV), Kiyo Pro extension (HDR, HDR mode, FoV, AF mode, Save), Systemd extension (Save and restore controls with Systemd path+service).
