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 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 5fa6438b25 Clean up calls to memset.
- Replaces all calls to memset with new FILL and FILL_ARRAY macros. The use
  of memset was inconsistent and we never use it for anything complicated.

Ari Koivula 1ccb3bd324 Move sign hiding stuff in rdoq to its own function.
- There is some stuff from sign hiding left intermingled with rdoq code,
  but I don't want to change the code too before testing that I didn't
  break anything.

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 8a407b0313 Estimate luma and chroma intra mode bits separately.
- Remove cu_info.intra[].cost and bitcost as unnecessary.
- Add luma_mode_bits to complement chroma_mode_bits and remove
  intra_pred_ratecost as unneccessary. Difference is that intra_pred_ratecost
  was more coarse and included chroma mode with the assumption that it would
  be the same as chroma.

Ari Koivula 51662e1081 Fix differences between cu_rd_cost_luma and rdo_cost_intra. 2014-10-03 11:36:57 +03:00
Ari Koivula 549ac96438 Change costs to doubles to avoid rounding intermediate results.
- Helps with debugging.

Ari Koivula 4e052d3f0f Wrap contexts of cabac_data inside cabac_data.ctx struct. 2014-09-24 01:02:37 +03:00
Ari Koivula 5f732126c3 Add cabac bit costs float table. 2014-09-15 15:45:43 +03:00
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 dceb3da9b8 Fix bug in search relating to transform with no non-zero coefficients.
- Because cost was calculated even though there were no coefficients, these
  very good modes were less likely to be selected.

- Added assert to encode_coeff_nxn to avoid these problems in the future.
2014-05-28 15:22:18 +03:00
Ari Koivula f9a603e4ea Move intra mode search form intra module to search module.
- Make the actual intra prediction function global.

- Move the rdo stuff to rdo module.

Ari Koivula 2ff713ccb2 Add new implementation for trskip decision. 2014-05-13 21:57:45 +03:00
Ari Koivula 0c65a9b658 Remove abs_sum from coeff quantization.
- It's meant for checking if there are any coefficients, but we don't use it
  and it's annoying to remember to initialize it and pass it around. The
  benefit should be quite small anyway.

Laurent Fasnacht 19b1642aa2 Removed all cabac parameters (cabac is part of encoder_state) 2014-04-22 11:46:53 +02:00
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.

Marko Viitanen 6558c92020 Clean up get_coeff_cost()
Since contexts were moved to cabac struct, there's no need to store contexts one by one
2014-04-09 11:50:17 +03:00
Ari Koivula 92ac5025f9 Take intra mode based coeff scan mode into account for coeff bit cost.
- Previously only diagonal scan mode, the most common one, would be used.

- This improved bdrate by 0.1-0.5 % for p0 and 0-0.2 % for p60.

- Working towards issue #11.
2014-04-04 12:56:24 +03:00
Ari Koivula 9563b50a34 Refactor coefficient group scan mapping lists.
The relation between coefficients positions and coefficient group positions
was a big confusing due to the use of 16x16 diagonal coefficient mappings
also as coefficient group mappings.

- Moved all coefficient group mappings to their own const arrays and added
  a new array the select the correct coefficient group mapping. This removes
  special cases for 8x8 and 32x32 transform sizes.

- Removed all coefficient group mapping initialization from init_sig_last_scan.

- Removed 128x128 and 64x64 from regular coefficient group array as those
  transform sizes don't exist anymore in HEVC.
