Ari Koivula 727fefacc4 Rename struct cabac_ctx to cabac_ctx_t. 2015-03-04 14:01:16 +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 36232619ab Fix broken cabac contexts in wpp. 
- Fixes #84.
- The issue was caused by 241b9d6 naively copying the whole struct, which
  contains data other than just the contexts. Rather than reverting the
  change, the struct was refactored to have another struct that contained
  just the contexts.

Ari Koivula 4e052d3f0f Wrap contexts of cabac_data inside cabac_data.ctx struct. 2014-09-24 01:02:37 +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.

Laurent Fasnacht b3d1754cc3 context_copy function 2014-05-08 15:04:51 +02:00
Laurent Fasnacht 19b1642aa2 Removed all cabac parameters (cabac is part of encoder_state) 2014-04-22 11:46:53 +02:00
Ari Koivula 11509c68dc Address clang-analyzer warnings about unused values. 
- Related to issue #35.
 2014-04-17 18:43:08 +03:00
Laurent Fasnacht 816ae13b1d Moved context information inside cabac_data. 
This is required in order to be able to work on parallelism.
 2014-04-04 14:28:50 +02:00
Laurent Fasnacht 946c815932 init_context directly has a QP parameter, instead of passing an encoder_control* 
This makes context less tightly coupled with encoder.

Marko Viitanen b09854d964 Implemented RDO function to calculate bits used for coefficient coding 2014-04-04 13:09:42 +03:00
Ari Koivula d44d1837bb Remove unreferenced parameters. 
- Working towards issue #11.
 2014-04-04 12:56:24 +03:00
Marko Viitanen cfb21c0e4c Implemented transform skipping (for 4x4 blocks) 
transform skip vs. normal transform selection criteria might need more work, currently both are calculated for each 4x4 block and SAD+coeff_SSE is compared.

Ari Koivula 47af5207c5 Remove dead code and fix white space. 2014-03-06 18:35:17 +02:00
Luca Barbato 934a4e3b88 whitespace: Drop trailing spaces 2014-02-21 15:03:35 +01:00
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.

Marko Viitanen de6faf623d Imported entropy bits array from HM and added macro to access it 2014-01-27 14:34:57 +02:00
Ari Koivula 77339efa57 Add COPYING file and add boilerplate for copyright and GPLv2 to every file. 2014-01-24 12:48:48 +02:00
Ari Koivula 3244c98b29 Fix sao cabac contexts. 
According to HM implementation, sao luma and chroma use the same contexts.

Ari Koivula 291be9507b Start adding Sample Adaptive Offset capability. 2013-10-25 10:39:42 +03:00
Ari Koivula d6932128aa Fix incorrect precedence. 
- This bug was due to incorrect translation of ternary to if-expression
  during refactoring. Addition has higher precedence than bit shift.

Ari Koivula 996769c725 Refactor: Move ctx_init from cabac to context. 2013-09-19 12:47:39 +03:00

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.
