You might be puzzled by the fact that x264 uses qscale values in several 
places instead of qp. Qscale is supposed to be a linear representation 
of the qp range, hence easier to use in usual computations.
There are qscale2qp and qp2qscale functions used to go from one kind of 
unit to the other one.
