wlr-mirror
wlr-mirror is a fork of
https://github.com/ProgAndy/wdomirror which fixes a
compilation issue and renames it to make it explicit that it relies on
wlroots.
It uses the wlroots dmabuf export protocol to create a mirror of an output with as little overhead as possible.
Building
meson build
ninja -C build
Usage
List the outputs and their IDs:
wlr-mirror
Create the mirror:
wlr-mirror $ID
wlr-mirror does not preserve the aspect ratio, so make sure to set
the size of the mirror window correctly. For fullscreen, make sure
that both source and target outputs have the same aspect ratio.
