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.

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 5fbb0a8c27 Fix includes 2016-08-10 13:05:40 +09:00
Arttu Ylä-Outinen 1dc94663c3 Bypass transform and quantization with --lossless.
When --lossless is given, set cu_transquant_bypass_flag for every CU and
bypass transform and quantization by directly copying reference pixels
to reconstruction and the residual to coefficients.

Arttu Ylä-Outinen ae832cda8c Pack cbf flags in cu_info_t to two bytes.
Reduces size of cu_info_t.
2016-06-16 20:24:19 +09:00
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)

Arttu Ylä-Outinen 49677810b5 Rename config module to cfg.
Prevents a conflict with config.h and src/config.h so that the config.h
generated by configure is included in global.h. Fixes problems with
large input files on 32-bit systems.

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.

Arttu Ylä-Outinen 8db8f3d523 Use macro SUB_SCU where possible.
Replaces expressions like (x & 0x3f) with SUB_SCU(x).

Arttu Ylä-Outinen 9532d79adb Add macros for indexing cu array in lcu_t.
- Adds macros LCU_GET_CU and LCU_GET_CU_AT_PX to cu.h.
- Replaces accesses to the cu array of lcu_t by calls to these macros.

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 804a3b648b Clean up quantization sign hiding.
- To allow for later configuration at runtime.

Ari Koivula 81ad583e08 Use the same coeff cost calculation for all rd modes.
- It's not worth it to have these faster approximations for coefficient cost.

Ari Koivula c9e212ba92 Add intra chroma mode search.
- Based on full chroma reconstruction so enabled only for --rd=2.

Ari Koivula 51662e1081 Fix differences between cu_rd_cost_luma and rdo_cost_intra. 2014-10-03 11:36:57 +03:00
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.

Ari Koivula f6272f06fc Unify signature for transform functions.

  and non-const output.

Ari Koivula 46b6b1243b Add --rd=3 mode and enable searching of intra depth 0.
- intra_build_reference_border was overflowing at depth 0 because it uses
  arrays just large enough to accommodate 32x32 transforms, which is the
  biggest transform.
- For similar reasons search_intra_rough doesn't work at depth 0.
- The --rd=3 mode tries all modes with transform search. It also works without
  rough search so it was used to test depth 0 search. If --rd=3 is not on intra
  split at depth 0 is not searched for.

Ari Koivula f0e990905e Remove chroma mode "36".
- It's an unnecessary chore to handle this special case everywhere (it means
  chroma_mode == intra_mode). Better just to use the actual mode.

Ari Koivula aee9bf2875 Re-add rdo control to transformskip decision.
- It got left out when rewriting the function.

Ari Koivula e947bd4c0e Clean up trskip decision code and remove old code.
- You can define structs inside functions! This changes everything!!

- Bitstream changes a little bit compared to old trskip decision. Bdrate
  change is insignificant though.
