Removing -minrate only changes nothing.
Removing -minrate, -maxrate and -bufsize (so only -b:v stays)
normalizes everything.
So issue is solved.
Now it's good time to ask me why i didn't try it initially :)
I decided to add these flags, because another time, working with very
continuous live streams, encoding with libx264, i saw that after time
like 24 hours, bitrate got much higher than what i set to bit_rate and
bit_rate_tolerance. Then, on #x264 IRC, i was advised to use such
