Marko Viitanen 18d9789fab Cabac context array for inter direction 2015-03-06 16:26:16 +02:00
Ari Koivula 1a62fee300 Rename struct cabac_data to cabac_data_t. 2015-03-04 14:01:16 +02:00
Ari Koivula 727fefacc4 Rename struct cabac_ctx to cabac_ctx_t. 2015-03-04 14:01:16 +02:00
Ari Koivula 8cd8240f7a Rename struct bitstream to bitstream_t. 2015-03-04 14:01:15 +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 4e052d3f0f Wrap contexts of cabac_data inside cabac_data.ctx struct. 2014-09-24 01:02:37 +03:00
Ari Koivula b339004c4c Rename cabac_state.ctx to cur_ctx. 2014-09-24 01:02:28 +03:00
Ari Koivula 35b2e6f755 Add missing cabac context for chroma cbf.
- The context was also missing from HM, but has been fixed in HM13.

Ari Koivula ab4041c8fc Change cabac debug statements to show information better.
- Show the number of bits when encoding multiple bins. I would like just the
  bits them selves in string form, but that's too much trouble for this.

- Print then as unsigned and coerce them to unsigned, as they are going
  get coerced to unsigned by the function call anyway.

- Change state to be less verbose.

Ari Koivula 47af5207c5 Remove dead code and fix white space. 2014-03-06 18:35:17 +02:00
Ari Koivula f4d5370e8b Fix compiler warnings for VS2010 /W4 in context.c and rdo.c.
- Working towards issue #11.
- Moved all const arrays from .h to the .c. These are not used anywhere else.
- Moved entropy_bits array and its helper macro to rdo.c. They are not used
  anywhere else.
- Implicit conversions to explicit ones.

Ari Koivula 66fe302520 Fix cabac context for sao. HM accepts encoded sao. 2013-11-04 13:03:51 +02:00
Ari Koivula 30c16fe299 Remove unused members from cabac_data.
- Removing them also makes cabac_init unnecessary.

Ari Koivula 627762dcd8 Refactor: Fix include guards.
- Remove _ from the beginning of include guards because that prefix is
  for the implementation.
- Move include guards to the beginning of file.
- Unify the syntax.

Ari Koivula 44a5498e30 Reorder includes to avoid hidden dependencies.
- Includes of global.h have been moved to headers because most headers
  require stdint.h.
- Includes required by the header have been moved from the .c to the header.
- Spaces have been added between includes to distinguish classes of includes.
