Way to start and stop recordings using keybindings

[samerickson]

Hi there, I am using swaywm and as far as I can tell the way you stop the recording is by pressing ctrl+c but is there a way to start and stop the recording without the requirement of having a terminal open?

yes, you can just kill the process with SIGINT (which is exactly what ctrl-c does)

here is something that works for me with sway:

bindsym Ctrl+Shift+Print exec wf-recorder -g "$$(~/bin/slurp)" -f ~/recording_$(date +"%Y-%m-%d_%H:%M:%S.mp4")
bindsym Ctrl+Shift+BackSpace exec killall -s SIGINT wf-recorder

Thanks for both of your help, I have been playing around with it. @mathroc thanks for your snippet including slurp.

The timeout command, assuming that it is installed on your system, can also be useful to record for a given amount of time (or to limit the recording time to a reasonable value). For instance, to record during 10 minute:
timeout -s SIGINT 10m wf-recorder
