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 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.

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.

Laurent Fasnacht 5fea5875a5 Huge refactoring
Split some parts of encoder_control into encoder_state
(idea: encoder_control is immutable)

Goal is to allow multiple substreams in the future.

Ari Koivula 40c2fa4d46 Change intra reconstruction to use the same prediction function as search.
- This fixes a bug with intra search. It sometimes used filtered reference
  pixels for 4x4 blocks leading to inaccurate cost estimate.
2014-04-10 12:09:19 +03:00
Ari Koivula 088dd9ab96 Clean up intra mode search.
- This changes the bitstream a little bit, because it changes the order in
  which the modes are tried and when two modes have the same cost the first
  one is chosen.

- Dst buffer was removes as it was no longer used.

Ari Koivula 8e63dd29bb Fix compiler warnings for VS2010 /W4 in intra.c.
- Working towards issue #11.
- Removed intra_get_block_mode as unused.
- Removed unused parameters from functions. Many of them were remnants from
  earlier data structures and earlier features of HEVC that have been removed.
- Lots of implicit conversions from larger types to smaller ones. I tried to
  avoid turning all of them to explicit ones this time and opted for changing
  the original data type instead. Had to do it in few cases though to stop the
  changes from propagating too widely.

Ari Koivula 7bb9c25447 Remove duplicate implementation of intra_build_reference_border.
The search_buildReferenceBorder was an ugly hack and a place for bugs to hide
that should never have existed. Now it doesn't.

The change reduces PSNR a little, but also reduces the bitrate, when the
expected result was to have no change in either. I'm guessing there was still
some bug in the search_buildReferenceBorder, but the bug could also be in
intra_build_reference_border. Will have to do more testing to be sure, but
having one place to look at will be better than having two.

Ari Koivula 5d12706510 Merge branch 'intra_NxN'
Conflicts:
	src/encoder.c

- Chroma RDOQ changes conflicted because I had moved the chroma
  quantization/dequantization to it's own function.
- Merged to master because I want my code to show up in github. =)
  All the old stuff still works, even though NxN doesn't work, so there
  is no reason not to merge anyway.
