wf-recorder is a utility program for screen recording of wlroots-based compositors (more specifically, those that support wlr-screencopy-v1 and xdg-output). Its dependencies are ffmpeg, wayland-client and wayland-protocols.

It’s usage is fairly simple:

This will record the selected area and save it at recording.mkv

wf-recorder -g "$(slurp)"

Output file can be controlled with -f

wf-recorder -g "$(slurp)" -f "test.mkv"
