Changes luma deblocking to use gather and scatter instead of reading
to and writing from here and there in memory. Should make them
faster and easier to vectorize, or at least cleaner.
Splits strong and weak luma deblocking to two functions, as they have
almost nothing in common.
Adds fields lambda, lambda_sqrt and qp to encoder_state_t. Drops field
cur_lambda_cost_sqrt from encoder_state_config_frame_t and renames
cur_lambda_cost to lambda.
Write bitstream without chroma when encoding with --input-format=P400.
This reduces bitstream size by 0-1 %, compared to coding monochrome in
420 format, and speeds up encoding slightly due to not processing
chroma.
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)
Prevents a conflict with config.h and src/config.h so that the config.h
generated by configure is included in global.h. Fixes problems with
large input files on 32-bit systems.
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.
- Adds function is_pu_boundary.
- Moves code for filtering an edge of a single PU or TU to a new
function filter_deblock_unit.
- Replaces recursive CU tree traversal in filter_deblock_cu with
a simple loop and renames it to filter_deblock_lcu_inside.
Replaces repetitive calls to kvz_filter_deblock_luma and
kvz_filter_deblock_chroma with loops in functions
filter_deblock_edge_luma and filter_deblock_edge_chroma.
Marks the following functions static and removes them from filter.h
since they are not used outside the filter module.
- kvz_filter_deblock_luma
- kvz_filter_deblock_chroma
- kvz_filter_deblock_edge_luma
- kvz_filter_deblock_edge_chroma
- kvz_filter_deblock_cu
- Replace parameter depth in kvz_filter_deblock_edge_{luma,chroma} with
length.
- Move checking whether an edge needs to be filtered from functions
kvz_filter_deblock_edge_{luma,chroma} to functions
kvz_filter_deblock_{cu,lcu}.
- Use pixel coordinates instead of 8-pixel block coordinates in
kvz_filter_deblock_cu.
- Add comments.
These changes should make it easier to modify the deblocking filter to
handle SMP and AMP blocks.
- 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.
- 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!
- It works just like the old structure except that the flags are checked with
bitmasks instead of having the flag value be propagated upwards. There isn't
really any benefit to this because the flags still have to be propagated to
parent CUs.
- Wrapped them inside a struct to make copying them easier. (Just need to copy
the struct instead of making individual copies)
