Ari Koivula a4ba794587 Optimize get_ep_ex_golomb_bitcost 
Arrange the decision tree such that there is only 3 branches on the
most common paths and the more likely branch is always fall-through.

A profile guided optimization pass would probably do something similar.

Ari Koivula 82cfab58f8 Improve fast mvd coding cost estimation 
A lot of time is being taken up by this function on ultrafast, and it
doesn't do a very good job. This change aims to both simplify the
logic and make the estimate better.

The logic is simplified by using a look up for the step mvd bit cost
step function instead of mimicking the binarization process. The
estimation is made better by checking fractional cabac bit costs.

The new function returns the same results as
kvz_get_mvd_coding_cost_cabac, but is also faster than the old
function.

Ari Koivula cff3bc8458 Merge branch 'monochrome' 2016-08-25 20:16:20 +03:00
Ari Koivula 4ec039004b Add monochrome encoding 
Write bitstream without chroma when encoding with --input-format=P400.
This reduces bitstream size by 0-1 %, compared to coding monochrome in
420 format, and speeds up encoding slightly due to not processing
chroma.
