I tried
./ffmpeg -f lavfi -i testsrc2 -bsf:v noise -bitexact -t 2 /tmp/.y4m

The day soldiers stop bringing you their problems is the day you have stopped 
leading them. They have either lost confidence that you can help or concluded 
you do not care. Either case is a failure of leadership. - Colin Powell
