Ari Lemmetti 2c069a3e5f Prevent unnecessary cu search
Prevent further analysis as soon as it is known that splitting can not improve cost
2017-01-30 16:21:41 +02:00
Arttu Ylä-Outinen 4f56b04239 Drop an unnecessary conditional
Drop a conditional for depth > MAX_DEPTH in search_cu. The depth cannot
be greater than MAX_DEPTH (== 3) since an earlier if-clause checks that
it is less than MAX_PU_DEPTH (== 4).

Arttu Ylä-Outinen ff5e5ec6d4 Record info about coded LCUs
Adds field lcu_stats to encoder_state_config_frame_t. The following data
is recorded for each LCU:
    - number of bits
    - squared cost
    - used lambda value
    - alpha parameter used for rate control
    - beta parameter used for rate control
2017-01-09 01:24:23 +09:00
Arttu Ylä-Outinen 640ff94ecd Use separate lambda and QP for each LCU
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.

Ari Koivula 4ec039004b Add monochrome encoding
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.

Ari Koivula cc08073615 Refactor some indexing weirdness in init_lcu_t
I thought there might be a bug in this so I cleaned it up.
2016-08-24 19:12:48 +03:00
Arttu Ylä-Outinen 2a946bd88e Rename encoder_state_t.global to frame
"Frame" is more accurate than "global" since when OWF is used, encoder
states for each frame have their own struct.

Arttu Ylä-Outinen 5fbb0a8c27 Fix includes 2016-08-10 13:05:40 +09:00
Arttu Ylä-Outinen cd7024b3a5 Skip computing SSD when using lossless coding.

2016-08-03 14:25:08 +09:00
Arttu Ylä-Outinen fbbe5d1844 Use kvz_pixels_calc_ssd for SSD in search.c.
Replaces loops for computing SSDs by calling kvz_pixels_calc_ssd in
search.c.
2016-08-03 14:25:08 +09:00
Arttu Ylä-Outinen ae832cda8c Pack cbf flags in cu_info_t to two bytes.

2016-06-16 20:24:19 +09:00
Arttu Ylä-Outinen cad2d496b8 Enable 4x8 and 4x16 partition modes
Enables search for 2NxN and Nx2N partition modes for 8x8 CUs and 2NxnU,
2NxnD, nLx2N and nRx2N partition modes for 16x16 CUs.

Changes the loop for copying reconstructed luma pixels in
kvz_inter_recon_lcu to use 4 byte chunks instead of 8 byte chunks since
it is now possible to have 4 pixel wide blocks.
2016-06-16 20:23:16 +09:00
Arttu Ylä-Outinen 2ae260e422 Change width of cells in lcu_t to 4 pixels.
Intra mode info for NxN partition units is now stored in the
corresponding 4x4 cell in lcu_t.cu array.

Arttu Ylä-Outinen 360f5bb8da Always use pixel coordinates for indexing lcu_t.
Removes macro LCU_GET_CU and uses LCU_GET_CU_AT_PX in its place.
2016-06-16 18:53:17 +09:00
Arttu Ylä-Outinen 57a3d9b4b9 Add a function for copying CU data from LCUs.
Adds function kvz_cu_array_copy_from_lcu which CU info data from an
lcu_t structure to a cu_array_t structure.

Arttu Ylä-Outinen 98aa906f30 Drop field coded from cu_info_t
It can be inferred from the position and size of the CU.
2016-06-14 12:21:57 +09:00
Arttu Ylä-Outinen 30e9ee988d Move bitcost field out of cu_info_t.inter.
The bitcost is only needed for the currently searched CU.

Fixes bitcost of the second PU being ignored when using SMP or AMP.

Jaakko Laitinen 0d361d5bc7 Moved cu split termination from a pre-processor to a input parameter. 2016-05-10 14:15:41 +03:00
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)
2016-04-01 17:46:55 +03:00
Arttu Ylä-Outinen 348ac4888b Fix calc_mode_bits.
The CUs left and above the current one would be set to NULL when there
was only one CU between the current one and the left or top edge of the
frame.
2016-03-04 14:08:35 +02:00
Ari Koivula 3dcc0957f8 Deal with impossible mv constraints
If 0,0 vector is illegal, it's possible that no legal movement vector,
is found, in which case a large cost is returned instead. The cost
overflowed and there is all sorts of silliness with converting from
double to int, but I'm not going to fix all of it because when we
remove the doubles it will all get fixed.

Ari Koivula eeafe14946 Clean up search initialization
Copy lcu explicitly instead of initializing with the same parameters.
2016-02-17 14:57:31 +02:00
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.

Ari Koivula a6ea705e19 Add missing lambda to some bit costs
Bits were being added to rate distortion without being multiplied by
lambda in a few places. Fixing this bug also finally allows us to remove
the magic bits from the Coding Unit split decision.

I tried to find new optimum value for CU_COST and it turned out to be 2
for veryslow and 0 for superfast. The difference between 0 and 2 on
veryslow was only 0.1% however, so I don't think this parameter is
needed any longer. Before this fix the effect of removing CU_COST would
have been 0.8%.
