Pauli Oikkonen a8dd6ce351 Add a note about having implemented a separate AVX2 version of SAO offset array calculation 2019-08-07 16:35:24 +03:00
Pauli Oikkonen 29563b7039 Make kvz_calc_sao_offset_array more obvious
Name temporary values from array lookups etc that are referred multiple
times to, to make the behavior of the mechanism more transparent. Define
all the constant values at the beginning of the function and declare as
const.

Arttu Ylä-Outinen 24ecddd2a5 Fix wrong strides in SAO reconstruction
Functions kvz_sao_reconstruct and encoder_sao_reconstruct used
frame->width as the stride instead of frame->rec->stride when accessing
frame->rec->data. This caused errors when using tiles and SAO.

Arttu Ylä-Outinen fdb3480b54 Enable strategies for SAO reconstruction
Re-enables strategies for SAO reconstruction. They were disabled in
commit ec9ff42.

Arttu Ylä-Outinen 1efa2708b2 Do SAO reconstruction for a single CTU at a time
Moves SAO reconstruction into encoder_state_worker_encode_lcu instead of
doing it in a separate step for the whole CTU row. Reconstruction of the
rightmost 10 pixels and bottommost 10 pixels of a CTU is delayed until
the neighboring CTU has been deblocked.

Doing SAO for the whole CTU row at a time caused unnecessary inter-CTU
dependencies when using WPP and OWF. The first CTU of a row would need
to wait until SAO was done for the row below in the previous frame.
Moving SAO reconstruction to immediately after deblocking each CTU fixes
this problem.

Arttu Ylä-Outinen ec9ff42077 Rewrite SAO recon to handle arbitrary sized blocks
Adds width and height parameters to function kvz_sao_reconstruct and
changes it to take coordinates in units of pixels. This will be useful
for doing SAO for areas smaller than a whole CTU.

Arttu Ylä-Outinen e78a8dfcf5 Copy the kvz_config passed to encoder_open
The kvz_config struct is created by the user but kvazaar keeps a pointer
to it. It is easy to break things by modifying the configuration outside
kvazaar. In addition, kvazaar modifies the struct even though it is has
a const modifier.

This commit changes the field cfg in encoder_control_t to be a copy of
the kvz_config struct instead of a pointer, removing modifications to
the const struct and allowing users to do whatever they want with it
after opening the encoder.

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.

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.

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 5fbb0a8c27 Fix includes 2016-08-10 13:05:40 +09:00
Arttu Ylä-Outinen 06b82bf888 Disable filters, trskip and signhide in lossless.
When lossless coding is used, deblock and SAO are skipped, transform
skip flag is not written and sign hiding is not 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)

Arttu Ylä-Outinen 626b53ce85 Move sao search from encoderstate to sao.
Moves sao search from function encoder_state_worker_encode_lcu in
encoderstate.c to function kvz_sao_search_lcu in sao.c. Makes functions
kvz_init_sao_info, kvz_sao_search_chroma and kvz_sao_search_luma static
since they are no longer used outside sao.c.

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 2276e0028f Fix coverity warning.
- False positive about use of an uninitialized value. Actually just
  copying uninitialized data from one struct to another.

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.
