Arttu Ylä-Outinen 405b8c1069 Refactor inter MVD cost functions
Moves duplicate code for writing the MVD of a single motion vector from
kvz_get_mvd_coding_cost_cabac and encoder_inter_prediction_unit to a new
function.

Arttu Ylä-Outinen c1cca1ad7f Refactor inter MV candidate selection
Moves duplicate code for checking the best MV candidate from functions
calc_mvd_cost, search_pu_inter_ref and search_pu_inter to a new
function.

Ari Lemmetti 14892fda00 Replace simple coefficient cost estimation with CABAC. Substantial improvement.
Approximation proved to be too inaccurate while not giving actually that much speedup.

Arttu Ylä-Outinen 328f051d7f Put inter search parameters in a single struct
Adds struct inter_search_info_t for holding the parameters that are used
by most function related to inter search. Passing the parameters in
a single struct greatly reduces the number of parameters for many
functions.

Arttu Ylä-Outinen d50ae6990c Add sum of absolute coefficients to strategies 2017-07-28 07:39:15 +03:00
Arttu Ylä-Outinen 59faca0646 Skip CABAC coefficient cost for --rd=0 2017-07-28 07:33:03 +03:00
Arttu Ylä-Outinen 2380ba0d41 Reduce copying in kvz_get_coeff_cost
Changes function kvz_get_coeff_cost to only copy the CABAC contexts and
not the whole encoder state.

Other threads could be simultaneously using the other parts of the
encoder state. Only copying the CABAC fixes a TSan data race warning.

Arttu Ylä-Outinen 5ddb43c6fe Fix undefined left shifts in rdo
Replaces left shifts by multiplications when the operand may be
a negative value. Left shift of a negative value is undefined behavior.

Miika Metsoila f8b6234fdb Changes to refence lists to behave more like L0/L1 lists from the specification 2017-06-27 16:05:15 +03:00
Arttu Ylä-Outinen 95775a1645 Change coefficient storage order
Changes coefficient storage order to a zig-zag order. Reduces
unnecessary copying of coefficients to temporary arrays.

Ari Lemmetti 47a9f0de04 Modify and use FILL_ARRAY macro to prevent warning on GCC 7
Following warning was given and is false positive

Ari Lemmetti 33ce101ab5 Revert "Use sizeof(uint32_t) to avoid warning in GCC7."
Did not fix the problem.

Arttu Ylä-Outinen 51786eda67 Drop redundant fields in encoder_control_t
Some of the fields in encoder_control_t were simply copies of the
corresponding fields in kvz_config. This commit drops the copied fields
in favor of using the fields in encoder_control_t.cfg directly.

Ari Koivula 4ceda1908b Fix OS-X compiler warning
rdo.c:475:25: warning: absolute value function 'abs' given an argument of type 'int64_t' (aka 'long long') but has parameter
       of type 'int' which may cause truncation of value [-Wabsolute-value]
         current.cost = -abs(quant_cost_in_bits) + (bits << PRECISION_INC);
                         ^
rdo.c:475:25: note: use function 'llabs' instead
         current.cost = -abs(quant_cost_in_bits) + (bits << PRECISION_INC);

Ari Koivula 6f61836989 Refactor kvz_rdoq_sign_hiding
Rename and reorder everything to make more sense.

- Moved input tables into their own struct and renamed them to what
  they actually represent.
- Renamed pretty much every variable to comform to our style and
  to make sense.
- Removed the lastCG stuff, as the function already gets passed the
  last coeff anyway. (it was named width, what the hell?)

Ari Koivula a85390d0ac Clean up code using the fixed point frac bit tables
This is to prepare for changing the code using the floating point table
to use the fixed point table instead.

This also allows reducing the size of the fractional part, which was
useful for finding every place where the the fixed point presentation
is relied upon.

Arttu Ylä-Outinen 640ff94ecd Use separate lambda and QP for each LCU
Adds fields lambda, lambda_sqrt and qp to encoder_state_t. Drops field
cur_lambda_cost_sqrt from encoder_state_config_frame_t and renames
cur_lambda_cost to lambda.

Eemeli Kallio f41e428e5f Removed kvz_skip_unnecessary_rdoq and reworked --rdoq-skip to skip 4x4 blocks when it is on. 2016-09-09 10:26:07 +03:00
Eemeli Kallio ed9c0b0416 RDOQ reworked in rdo.c. rdoq_signhide now skips coeffs that are after best_last_idx. 2016-09-09 10:16:51 +03:00

Eemeli Kallio 99d8b9abeb Changed skip_rdoq name to kvz_skip_unnecessary_rdoq. Changed the order it uses when it goes through CGs and tuned its sum calculation. 2016-08-18 14:02:56 +03:00
Eemeli Kallio d20ac03ca2 Added --rdoq-skip option 2016-08-18 12:17:53 +03:00
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.

encoderstate.c to encode_coding_tree.c.

Arttu Ylä-Outinen 7836ff6ec9 Drop unused functions.
Removes functions kvz_coefficients_calc_abs, kvz_intra_rdo_cost_compare
and kvz_rdo_cost_intra which are no longer used.

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 947bae24f9 Update Doxygen documentation
Add module information to all header files.

Update all header file documentations to briefly say what they are, and
to use the javadoc format so the brief actually gets included into the
doxygen documentation.

Remove \file from implementation files, in order to not repeat the info
from the header files.

Add files under strategies and tools to Doxygen and update the Doxygen
settings to be just plain better.

Make README be the main page of Doxygen documentation.

Ari Koivula 2f79bfebf7 Rename parameter encoder_state to state in all functions.
- It's so widely used that there isn't really need to emphasize that
  it's the encoders state. Also, it isn't really the encoders state,
  but encoding jobs state.
