Ari Lemmetti 2343958a14 Fix transform split for small luma blocks 2019-08-24 21:50:17 +03:00
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 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.
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 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)

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 7280dbf429 Remove unnecessary function
This function used to be more complicated, but now it's so simple that
it's just obfuscating what's happening.

Ari Koivula 1221e4c7d2 Remove old intra prediction code. 2015-10-05 05:30:47 +03:00

Ari Koivula 678a1dd1dd Switch to new intra pred in kvz_intra_recon_lcu_luma 2015-10-05 02:29:02 +03:00
Ari Koivula cd2f1797bf Add reimplemented intra prediction code
Just along side for now to help with debugging.

The main difference with the new versions is that they take and output
width**2 blocks and two width*2+1 arrays of reference samples,
instead of the (2*width+8)**2 blocks the old ones do. This should make
the interface clearer and the memory footprint smaller.

Also commented the shit out of angular prediction, so hopefully Ari L.
will have an easier time with a SIMD implementation.

- Remove dead code.

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 e9b8d9b889 Fix gcc warnings.
- Remove unused variables.
- Change intra prediction functions to take their inputs as const pointers.
- Change intra_get_pred to take two pointers instead of an array of pointers,
  because the warnings got just too exotic.

Ari Koivula bc7d7d5cb6 Add cu_info* as parameter to reconstruction functions.
- This is required so these functions can be used for searching. When NULL
  is given they take the CU from LCU struct as they did previously.
