Ari Lemmetti e3c3e74926 Use sizeof(uint32_t) to avoid warning in GCC7.
error: 'memset' used with length equal to number of elements without multiplication by element size [-Werror=memset-elt-size]

Ari Lemmetti b021d2244e Reduce more unnecessary initializations. 2017-02-16 17:25:26 +02:00
Ari Lemmetti acd12cba1e Remove unnecessary memory initialization to zero
Values in interval [last_scanpos, 0] are overwritten in following for loop, except for the sig_coeff_inc value.

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

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.

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)

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.

Ari Koivula d7383ccb25 Change license to LGPL.
- Everyone who has contributed code to the project has been asked to license
  their contributions under LPGL and they have agreed.

- COPYING file changed to say LGPLv2.1 instead of GPLv2.

- GPL changed to LGPL in the header of every single file that a header and
  header added to the few that were missing one.

- Also.. Happy new year!

Ari Koivula 5fa6438b25 Clean up calls to memset.
- Replaces all calls to memset with new FILL and FILL_ARRAY macros. The use
  of memset was inconsistent and we never use it for anything complicated.
2015-02-19 16:25:28 +02:00
Ari Koivula 1ccb3bd324 Move sign hiding stuff in rdoq to its own function.
- There is some stuff from sign hiding left intermingled with rdoq code,
  but I don't want to change the code too before testing that I didn't
  break anything.

Ari Koivula 81ad583e08 Use the same coeff cost calculation for all rd modes.
- It's not worth it to have these faster approximations for coefficient cost.
2015-01-20 17:34:59 +02:00
Ari Koivula 8a407b0313 Estimate luma and chroma intra mode bits separately.
- Remove cu_info.intra[].cost and bitcost as unnecessary.
- Add luma_mode_bits to complement chroma_mode_bits and remove
  intra_pred_ratecost as unneccessary. Difference is that intra_pred_ratecost
  was more coarse and included chroma mode with the assumption that it would
  be the same as chroma.

Ari Koivula 46b6b1243b Add --rd=3 mode and enable searching of intra depth 0.
- intra_build_reference_border was overflowing at depth 0 because it uses
  arrays just large enough to accommodate 32x32 transforms, which is the
  biggest transform.
- For similar reasons search_intra_rough doesn't work at depth 0.
- The --rd=3 mode tries all modes with transform search. It also works without
  rough search so it was used to test depth 0 search. If --rd=3 is not on intra
  split at depth 0 is not searched for.

Ari Koivula dceb3da9b8 Fix bug in search relating to transform with no non-zero coefficients.
- Because cost was calculated even though there were no coefficients, these
  very good modes were less likely to be selected.

- Added assert to encode_coeff_nxn to avoid these problems in the future.
2014-05-28 15:22:18 +03:00
Ari Koivula f9a603e4ea Move intra mode search form intra module to search module.

Ari Koivula 0c65a9b658 Remove abs_sum from coeff quantization.
- It's meant for checking if there are any coefficients, but we don't use it
  and it's annoying to remember to initialize it and pass it around. The
  benefit should be quite small anyway.

Ari Koivula 92ac5025f9 Take intra mode based coeff scan mode into account for coeff bit cost.

Ari Koivula 9563b50a34 Refactor coefficient group scan mapping lists.
The relation between coefficients positions and coefficient group positions
was a big confusing due to the use of 16x16 diagonal coefficient mappings
also as coefficient group mappings.

- Moved all coefficient group mappings to their own const arrays and added
  a new array the select the correct coefficient group mapping. This removes
  special cases for 8x8 and 32x32 transform sizes.

- Removed all coefficient group mapping initialization from init_sig_last_scan.

- Removed 128x128 and 64x64 from regular coefficient group array as those
  transform sizes don't exist anymore in HEVC.
