Should be 0(auto) and fixed, thanks.

Also added log_level and qp, and moved min_qp/max_qp/initial_qp to the case
with no bit_rate. Hope this version looks better :)

s.
If "RateControl" is opened, the "initial_qp" will be used for the first frame
and kept for all the other frames (constant-QP) and if there is no rate
control, the initial_qp will only work for the first frame (xavs2 will always
initial the qp for the first frame). So...maybe better with "initial"?
Thanks,
Huiwen Ren
