Ari Lemmetti aa0ade3f65 Cast values to unsigned to make UBSan not trigger due to left-shifting negatives 2020-03-16 19:52:34 +02:00
Ari Lemmetti 800fc8644d Reset CBFs because CBFs might have been set earlier for depth earlier. 2019-08-24 21:49:33 +03:00
Arttu Ylä-Outinen c438bb4a19 Add an option to skip CABAC for residual costs
Adds command line option --fast-residual-cost=<limit>. When QP is below
the limit, estimates the cost of coding the residual coefficients from
the sum of absolute coefficients. Skipping CABAC is not worth it with
high QPs because there are fewer coefficients so CABAC is not as slow.

Arttu Ylä-Outinen fb462b25ef Fix transform skip for inter
The transform skip flag in cu_info_t was stored under the intra
substruct even though transform skip can be used for inter as well. This
caused bitstream errors. Fixed by moving the flag out of the substruct.

Arttu Ylä-Outinen c74ede148b Fix CBF flags for 4x4 luma blocks
CBF flags were not being propagated to the upper level from blocks of
size 4x4.

Arttu Ylä-Outinen 0a69e6d18f Fix selection of transform function for 4x4 blocks
DST function was returned for inter luma transform blocks of size 4x4
even though they must use DCT. Fixed by checking the prediction mode of
the block in addition to whether it is chroma or luma.

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 95775a1645 Change coefficient storage order
Changes coefficient storage order to a zig-zag order. Reduces
unnecessary copying of coefficients to temporary arrays.

Arttu Ylä-Outinen 9395867a9a Quantize all colors in a single traversal
Changes kvz_quantize_lcu_residual to process all three colors in
a single traversal of the TU tree.
2017-05-12 16:42:41 +03:00
Arttu Ylä-Outinen 1e58fd6b16 Split kvz_quantize_lcu_residual
Splits kvz_quantize_lcu_residual to two functions that handle the TU
tree recursion and quantization of a single TU.

Arttu Ylä-Outinen cc87e0dcc7 Combine luma and chroma quantization functions
Replaces functions kvz_quantize_lcu_luma_residual and
kvz_quantize_lcu_chroma_residual in transform.c with function
kvz_quantize_lcu_residual. The new function can handle any of the YUV
colors. Removes some duplicated code.

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.
2017-02-09 14:05:28 +09:00
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.

Arttu Ylä-Outinen 5fb7afe8c4 Add --implicit-rdpcm command line parameter.
Makes it possible to use lossless coding without implicit residual DPCM.
2016-10-03 20:01:55 +09:00
Arttu Ylä-Outinen 5affc0f527 Use implicit RDPCM in lossless mode.
Sets implicit RDPCM flag in SPS when lossy coding is disabled and
applies DPCM to intra residual when prediction mode is horizontal or
vertical.

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 1dc94663c3 Bypass transform and quantization with --lossless.
When --lossless is given, set cu_transquant_bypass_flag for every CU and
bypass transform and quantization by directly copying reference pixels
to reconstruction and the residual to coefficients.

Arttu Ylä-Outinen ae832cda8c Pack cbf flags in cu_info_t to two bytes.

Arttu Ylä-Outinen 2ae260e422 Change width of cells in lcu_t to 4 pixels.
Intra mode info for NxN partition units is now stored in the
corresponding 4x4 cell in lcu_t.cu array.

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)

Arttu Ylä-Outinen 49677810b5 Rename config module to cfg.
Prevents a conflict with config.h and src/config.h so that the config.h
generated by configure is included in global.h. Fixes problems with
large input files on 32-bit systems.

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!
