how record video without lags

[tom2374]

I have a weak computer and when I record video using ffmpeg or OBS they use 80 percent of the processor, so everything freezes when recording. Is there a lightweight utility or a way to not lose performance so much?
my start ffmpeg

Code: Select all

ffmpeg -f x11grab -framerate 1 -video_size 1920x1080 -i :0.0 -vframes 1 output.jpeg
