## Recording while using replay/streaming ## Recording while using replay/streaming
You can record a regular video while using replay/streaming by launching GPU Screen Recorder with the `-ro` option to specify a directory where to save the recording.\ You can record a regular video while using replay/streaming by launching GPU Screen Recorder with the `-ro` option to specify a directory where to save the recording.\
To start/stop (and save) recording use the SIGRTMIN signal, for example `pkill -SIGRTMIN -f gpu-screen-recorder`. The name of the video will be displayed in stdout when saving the video. To start/stop (and save) recording use the SIGRTMIN signal, for example `pkill -SIGRTMIN -f gpu-screen-recorder`. The name of the video will be displayed in stdout when saving the video.\
This way of recording while using replay/streaming is more efficient than running GPU Screen Recorder multiple times since this way it only records the screen and encodes the video once.
