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 4876879b82 Add IWYU pragmas 2016-03-31 12:33:34 +03:00
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 3a10e9e3e0 Prefix all non-static symbols with "kvz_". 2015-08-26 13:02:28 +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.
2015-03-04 17:31:07 +02:00
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!

Laurent Fasnacht 2e821b79a9 encoder_state in now in encoder_state.[ch] 2014-06-03 13:51:30 +02:00
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
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
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 0fd9105f0a Fix sao type context init values.
The initialization slice types are in reverse order compared to the codes used
for slice types. They are BPI instead of IPB.
2013-10-25 10:51:11 +03:00
Ari Koivula 3244c98b29 Fix sao cabac contexts.
According to HM implementation, sao luma and chroma use the same contexts.

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.

Marko Viitanen 0a6c38a8e9 Refactor: context.h renaming 2013-09-18 14:33:47 +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.
