Arttu Ylä-Outinen 328f051d7f Put inter search parameters in a single struct
Adds struct inter_search_info_t for holding the parameters that are used
by most function related to inter search. Passing the parameters in
a single struct greatly reduces the number of parameters for many
functions.

Arttu Ylä-Outinen 2f2c281e8e Fix a memory leak in crypto
A CryptoPP::CFB_Mode<CryptoPP::AES>::Encryption was allocated at the
beginning of encoder_state_encode_leaf and was never freed. This commit
changes encoder_state_worker_encode_lcu to delete the CFB_Mode. Also
moves crypto handle from encoder_state_config_tile_t to encoder_state_t
so that it can be safely deleted without affecting other threads in the
same tile.

Arttu Ylä-Outinen 22155950c1 Rewrite crypto to conform to kvazaar code style 2017-05-23 11:51:25 +03:00
Arttu Ylä-Outinen e78a8dfcf5 Copy the kvz_config passed to encoder_open
The kvz_config struct is created by the user but kvazaar keeps a pointer
to it. It is easy to break things by modifying the configuration outside
kvazaar. In addition, kvazaar modifies the struct even though it is has
a const modifier.

This commit changes the field cfg in encoder_control_t to be a copy of
the kvz_config struct instead of a pointer, removing modifications to
the const struct and allowing users to do whatever they want with it
after opening the encoder.

Ari Koivula 04cd875b2c Move substream finalization to LCU coding job
Having some of the termination bits in the LCU coding and some in the
substream finalization was needlessly confusing. Doing substream
finalization directly after LCU coding makes it easy to verify that the
finalization is done correctly.

Removes one job per WPP row from the job queue.

Removes kvz_cabac_flush, because I don't like bits being put into the
bitstream implicitly. Better to have it all in the open.

Ari Koivula a9e45efcfc Add a fast lane for byte-aligned bitstream writes
The CABAC engine only writes to the bitstream when it has a full byte.
These writes are also always byte-aligned, so there is no need to even
check for stream alignment.

Speedup was around 3% with ultrafast and low QP.

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 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.

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 b1596eb76c Refactor coding of end_of_slice_segment_flag.
According to spec the end_of_slice_segment_flag is always coded, but in the
code it looked like it was not coded for the last LCU in picture. This was
due to the end_of_slice_segment_flag being coded inside cabac_flush, like it
is in HM. This is a bit silly so I moved it out of cabac_flush.

  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.
