I may misunderstand but you have to turn the screen 
lock off if you don't want the screen to get locked.
(FFmpeg does not turn it off.)

Some comments:
Do not use sudo when running ffmpeg (yes, security 
issues exist).
Use -framerate instead of -r for x11grab.
The sameq option did not work the way you believe 
it worked, it was therefore removed years ago.
