Comment (by LordHDL):

 When I try -frame_rate 60 it gives me this:


 {{{
 [AVFoundation input device @ 0x7feea8501a00] Value 60.000000 for parameter
 'frame_rate' out of range [0.1 - 30]
 [AVFoundation input device @ 0x7feea8501a00] Error setting option
 frame_rate to value 60.
 : Result too large
 }}}

 Any value between the specified range will result in enormous CPU usage
 and a failure to stop upon pressing Q (or perhaps it just takes a really
 long time).
