Arttu Ylä-Outinen 018b5ffa64 Move inter CU reconstruction to a new function

kvz_inter_recon_cu in inter.c.

Arttu Ylä-Outinen 9974380cdd Fix bipred and temporal MVP
- Fixes two errors in calculating the POC for the reference frame for
  temporal candidate MV scaling.
- Fixes using the MV for the wrong direction when the temporal MV
  predictor block uses bi-prediction.

Fixes #160.

Arttu Ylä-Outinen b6d793ef33 Drop field inter.mvd from cu_info_t
Instead of storing the mv differences in cu_info_t, they are computed
from the mv candidates and the motion vector. Reduces the size of
cu_info_t.

Arttu Ylä-Outinen 98aa906f30 Drop field coded from cu_info_t
It can be inferred from the position and size of the CU.

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 dc4525c0e3 Implement inter recon for non-square blocks.
Adds parameter height to functions kvz_inter_recon_lcu and
kvz_inter_recon_lcu_bipred and makes them work on non-square sizes.
Fractional reconstruction functions do not handle non-square blocks yet.

  candidates A1 and B1.

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 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 5fea5875a5 Huge refactoring
Split some parts of encoder_control into encoder_state

Goal is to allow multiple substreams in the future.

Marko Viitanen db266e74ff Added merge mode selection (NOT WORKING!) and a function to get candidates 2013-10-18 11:39:32 +03:00
Marko Viitanen 52335adda0 Split merge candidate derivation to its own function 2013-10-18 11:39:32 +03:00
Ari Koivula 681975ad4b Fix inter reconstruction for 8x8 blocks and enable 8x8 inter blocks again.
Inter reconstruction was modifying the movement in place when it shouldn't
have. This was causing issues only for the 8x8 blocks, because for larger
blocks the modified movement vector was too far away to be seen by the blocks
below it.
