wl-mirror

Simple Wayland output mirror client

wl-mirror attempts to provide a solution to sway's lack of output mirroring by mirroring an output onto a client surface. Features: - Mirror an output onto a resizable window - Mirror an output onto another output by fullscreening the window - Reacts to changes in output scale - Preserves aspect ratio - Corrects for flipped or rotated outputs - Supports custom flips or rotations - Supports mirroring custom regions of outputs - Supports receiving additional options on stdin for changing the mirrored screen or region on the fly (works best when used with pipectl)
