Eemeli Kallio 9f605152ae Changed intra to use best rough cost when using inter and rd=2 2017-04-05 13:01:32 +03:00
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.

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.

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 ae832cda8c Pack cbf flags in cu_info_t to two bytes.
Reduces size of cu_info_t.

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.

Arttu Ylä-Outinen 360f5bb8da Always use pixel coordinates for indexing lcu_t.
Removes macro LCU_GET_CU and uses LCU_GET_CU_AT_PX in its place.

Arttu Ylä-Outinen 1cbe844f79 Move inter and intra into an union in cu_info_t.
Reduces size of cu_info_t.

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.
