Ari Koivula 2c005cda25 Fix bug with sub-pixel motion estimation in tiles 
The width of the tile was being used to index the frame pixel buffer
instead of the width of the buffer.

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.

Arttu Ylä-Outinen 2a946bd88e Rename encoder_state_t.global to frame 
"Frame" is more accurate than "global" since when OWF is used, encoder
states for each frame have their own struct.

Arttu Ylä-Outinen 097bf8f3c0 Add a typedef for mvd coding cost functions. 2016-06-20 13:56:10 +09:00
Arttu Ylä-Outinen cad2d496b8 Enable 4x8 and 4x16 partition modes 
Enables search for 2NxN and Nx2N partition modes for 8x8 CUs and 2NxnU,
2NxnD, nLx2N and nRx2N partition modes for 16x16 CUs.

Changes the loop for copying reconstructed luma pixels in
kvz_inter_recon_lcu to use 4 byte chunks instead of 8 byte chunks since
it is now possible to have 4 pixel wide blocks.

Arttu Ylä-Outinen 46e8122d27 Add functions for indexing cu_array_t structures.

Arttu Ylä-Outinen b6d793ef33 Drop field inter.mvd from cu_info_t 
Instead of storing the mv differences in cu_info_t, they are computed
from the mv candidates and the motion vector. Reduces the size of
cu_info_t.
 2016-06-14 12:21:57 +09:00
Arttu Ylä-Outinen ebb10763f1 Drop field inter.mv_ref_coded from cu_info_t. 
Storing inter.mv_ref_coded in cu_info_t is unnecessary since it can be
computed from refmap and inter.mv_ref.

Arttu Ylä-Outinen 30e9ee988d Move bitcost field out of cu_info_t.inter.

Ari Koivula 61fc3e87ba Run include-what-you-use fix_includes.py fix_includes.py 
The includes should make more sense now and not just happen to compile
due to headers included from other headers.

Used a modified version of IWYU. Modifications were to attribute int8_t
and so on to stdint.h instead of sys/types.h and immintrin.h instead of
more specific headers.

include-what-you-use 0.7 (git:b70df35)
based on clang version 3.9.0 (trunk 264728)

Ari Koivula e23ed231fb Fix race condition with owf and non-square motion partitions 
The OWF wpp limit code assumed square blocks, and as such did not work
correctly when height != width. This changes the relevant code to consider
both height and width.

Ari Koivula b0c3ece31e Fix race condition when deblocking is on but SAO is off 
Already suspected this yesterday, but didn't want to add the code to
handle it before confirming that it's actually a problem. It is.
 2016-03-09 14:02:46 +02:00
Ari Koivula 1671725c72 Fix non-determinism issue with OWF WPP margin 
The previous reasoning used deblocking and fractional motion estimation
together to arrive at a margin of 4 pixels. This was wrong, and with
either of these off, half pixel chroma interpolation could use pixels
outside the intended region.

Deblocking does not currently affect the margin needed.

Ari Koivula aec152c953 Fix OWF mv restriction limit 
The check was done in regard to the wrong dimension, allowing the
access to unfinished parts of the frame when coding multiple frames
at the same time.
