Joose Sainio 072b84711a [jccr] fix 64×64 CUs 2021-09-06 11:28:20 +03:00
Joose Sainio 042b5078d8 [jccr] WIP initial implementation
Add somekind of search for joint chroma residual coding.
Bitstream is currently correct but prediction is incorrect because the jccr
is actually not used in the search.

Hard coded to be enabled

Arttu Ylä-Outinen 8b2483ca1c Combine intra reconstruction functions
Replaces function kvz_intra_recon_lcu_luma and
kvz_intra_recon_lcu_chroma in intra.c with function kvz_intra_recon_cu.
The new function can handle reconstruction for both luma and chroma.
Removes some duplicated code.

Arttu Ylä-Outinen e67fdb853d Move intra leaf TB recon to a separate function
Moves code for intra leaf transform block reconstruction from functions
kvz_intra_recon_lcu_luma and kvz_intra_recon_lcu_chroma to a new
function intra_recon_tb_leaf. Removes some duplicated code.

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.

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.

Pierre-Loup Cabarat 2b8ce5e47c Add intra prediction modes encryption 2017-03-06 17:27:39 +01:00
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 5affc0f527 Use implicit RDPCM in lossless mode.

applies DPCM to intra residual when prediction mode is horizontal or
vertical.

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.
