In zoom-client
(from snap) I can choose whether to use HD video or not, and turns out this setting persists when I close Zoom and open Cheese. It makes me think that this setting is global instead of zoom specific. Unfortunately Cheese doesn't have this setting, so that I need to open Zoom just to change this setting.
My question is, can I change webcam resolution without opening Zoom, probably via a terminal command line or a setting GUI (such as gnome settings)?
