examples:
$ ffmpeg -f x11grab -r 15 -s 1920x1200 -i :0.0+0,0 -c:v libx264 -preset faster -pix_fmt yuv420p -f flv rtmp://localhost/live/test
$ ffmpeg -f x11grab -r 30 -s 1920x1200 -i :0.0+0,0 -vcodec rawvideo -pix_fmt yuv420p -threads 2 -f v4l2 /dev/video0

note the latter example would require v4l2loopback:
