As far as I remember on Windows the sleep API as used by ffmpeg provides 
less accurate timing, and no platform-specific timers are implemented for 
Windows which could provide higher accuracy. You can try 
setting/increasing burst_bits which should increase the bitrate but cause 
slighly bigger bursts.
