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.

Pierre-Loup Cabarat 2b8ce5e47c Add intra prediction modes encryption 2017-03-06 17:27:39 +01:00
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 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 4876879b82 Add IWYU pragmas 2016-03-31 12:33:34 +03:00
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 ff976e2afc Arrange parameters in intra fancily 2015-10-05 06:23:14 +03:00
Ari Koivula d83d57df1a Fix function names in intra
Prefix non-static functions with kvz_intra_ and static with intra_.

Ari Koivula 30b4fa4247 Rename intra prediction to kvz_intra_predict 2015-10-05 06:23:14 +03:00
Ari Koivula 1221e4c7d2 Remove old intra prediction code. 2015-10-05 05:30:47 +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.

Arttu Ylä-Outinen 3a10e9e3e0 Prefix all non-static symbols with "kvz_". 2015-08-26 13:02:28 +03:00
Arttu Ylä-Outinen f7f17a060c Rename pixel_t to kvz_pixel. 2015-07-02 16:58:28 +03:00
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 ded6fd9ee8 Renamed typedef pixel to pixel_t. 2015-03-04 16:35:53 +02:00

Ari Koivula b14f89c88f Rename struct encoder_state to encoder_state_t. 2015-03-04 14:00:46 +02:00
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.
