Sami Ahovainio 4768ba0628 Minor fixes to header writing. Added contexts for multi_ref_line and BDPCM. Functions added for writing both in bitstream, but they are both disabled for now. 2019-05-29 13:00:19 +03:00
Sami Ahovainio 5b46fbd878 Added multi_ref_idx variable for intra coding (is 0 throughout the code for now). Modified prediction flag writing. Chroma pred flag remains unchanged (ToDo). Added bitstream debug printing on VERBOSE mode. 2019-05-21 12:28:05 +03:00

Arttu Ylä-Outinen c438bb4a19 Add an option to skip CABAC for residual costs 
Adds command line option --fast-residual-cost=<limit>. When QP is below
the limit, estimates the cost of coding the residual coefficients from
the sum of absolute coefficients. Skipping CABAC is not worth it with
high QPs because there are fewer coefficients so CABAC is not as slow.
 2018-07-16 12:31:20 +03:00
Arttu Ylä-Outinen a343f6d587 Prepare for delta QPs at CU-level 
- Replaces lcu_dqp_enabled with max_qp_delta_depth in encoder_control_t.
- Fixes set_cu_qps so that it can handle quantization groups of
  arbitrary size.
- Fixes computation of QP predictors so that it works for quantization
  groups of arbitrary size.

Arttu Ylä-Outinen 8c53417006 Check zero coefficient cost for inter 
Checks the cost of flushing all coefficients of an inter block to zero.
This is much faster than doing full RDOQ but can still reduce bitrate
significantly. Encoding speed is increased since fewer coefficient bits
have to be coded with CABAC.

Arttu Ylä-Outinen 018b5ffa64 Move inter CU reconstruction to a new function 
Moves code for reconstructing all PUs in an inter CU to a new function
kvz_inter_recon_cu in inter.c.
 2018-01-24 15:05:39 +02:00
Arttu Ylä-Outinen 9067aa4535 Remove an unnecessary copy in SMP/AMP search 
SMP/AMP search is performed using a lower work tree level than the
normal inter search so the prediction info must be copied up if an
SMP/AMP mode is chosen. Previously pixels and coefficient were copied as
well. Changed to only copy prediction info.

Arttu Ylä-Outinen fc43643ba5 Use a transform split for SMP and AMP blocks 2018-01-18 10:36:25 +02:00
Arttu Ylä-Outinen 649113a821 Fix inter search being used for 4x4 blocks 
When 4x4 intra blocks are enabled and inter search is limited to 16x16
and larger blocks, it is possible that inter search is accidentally done
for 4x4 blocks. Fixed by checking that block size is at least 8x8 before
doing inter search.
 2018-01-10 14:21:48 +02:00
Ari Lemmetti 14892fda00 Replace simple coefficient cost estimation with CABAC. Substantial improvement. 
Approximation proved to be too inaccurate while not giving actually that much speedup.

Arttu Ylä-Outinen 1357dd0599 Pass coeffs through encoder state 
Changes the way coefficients are passed from kvz_search_lcu to
kvz_encode_coding_tree. Drops fields coeff_y, coeff_u and coeff_v in
videoframe_t and instead passes them through field coeff in
endoder_state_t.

Arttu Ylä-Outinen 2f2405dfe6 Fix crash when PU depth is limited 
When video width or height was not a multiple of the smallest CU size,
no prediction would be performed at the border CUs. Kvazaar would later
crash at an assertion failure when attempting to write the bitstream for
the CU.

Fixed by permitting inter and intra prediction when the CU split is
forced, even if CUs of that size would otherwise be disabled.

Arttu Ylä-Outinen 51786eda67 Drop redundant fields in encoder_control_t 
Some of the fields in encoder_control_t were simply copies of the
corresponding fields in kvz_config. This commit drops the copied fields
in favor of using the fields in encoder_control_t.cfg directly.
 2017-02-09 14:05:28 +09:00
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 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

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.

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.

 2016-06-14 12:21:57 +09:00
Arttu Ylä-Outinen 30e9ee988d Move bitcost field out of cu_info_t.inter.

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.

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

 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 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%.

- The cost of the first mode in the mode list was returned instead of cost of
  the selected mode, as this used to be the best mode when the list was
  sorted. Should only matter when doing inter coding.
- This pretty much affects only --rd=1 in inter frames.

- Remove cu_info.intra[].cost and bitcost as unnecessary.
- Add luma_mode_bits to complement chroma_mode_bits and remove
  intra_pred_ratecost as unneccessary. Difference is that intra_pred_ratecost
  was more coarse and included chroma mode with the assumption that it would
  be the same as chroma.

Ari Koivula 3868cc7ff1 Fix crash on inter search when --tr-depth-intra is used. 
- Transform splits meant for intra modes were used for inter when inter mode

  block didn't have any coefficients.
 2014-10-03 19:29:06 +03:00

 2014-09-11 10:56:53 +03:00
Ari Koivula 46b6b1243b Add --rd=3 mode and enable searching of intra depth 0. 
- intra_build_reference_border was overflowing at depth 0 because it uses
  arrays just large enough to accommodate 32x32 transforms, which is the
  biggest transform.
- For similar reasons search_intra_rough doesn't work at depth 0.
- The --rd=3 mode tries all modes with transform search. It also works without
  rough search so it was used to test depth 0 search. If --rd=3 is not on intra
  split at depth 0 is not searched for.

- Add encoder_state->global->cur_lambda_cost_sqrt.

- Use sqrt lambda for inter search and rough intra search.

- The effect on inter is around 10-20% bdrate. The effect on intra is smaller
  and non-existent when --rd=2 is enabled, as the intra search refinement was
  already done with SSD and correct lambda.

picture.slice_sao_chroma_flag -> 1 (was constant)

This may be changed later. For now it's better to avoid having slice related stuff in picture.

Ari Koivula bdc16d2612 Improve cu_info coded block flag data structure a bit. 
- 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)
 2014-05-06 18:28:04 +03:00
Ari Koivula 4490e8afd6 Remove depth dimension from picture->cu_array.

Ari Koivula 088dd9ab96 Clean up intra mode search. 
- This changes the bitstream a little bit, because it changes the order in
  which the modes are tried and when two modes have the same cost the first
  one is chosen.

- Dst buffer was removes as it was no longer used.

Ari Koivula 92ac5025f9 Take intra mode based coeff scan mode into account for coeff bit cost.

  block for NxN.

- This fix should improve bdrate by about 1%.

In the future we might even have just a const pointer to reference pixels.
 2014-03-19 16:01:31 +02:00
Ari Koivula 7328fc2897 Add special handling for bottom right LCU pixel. 
I didn't take into account that the reference pixel on the top-left of the
LCU gets over written if we just replace the top reference pixels for
current LCU with the bottom reference pixels after doing the search.
To handle this I copy the pixel that gets overwritten to the vertical
reference pixels.
 2014-03-19 16:01:31 +02:00
Ari Koivula 57ce7e990b Add new reference pixel buffer management to encoding loop. 
- This is necessary because after we add in-loop filters to be done per LCU,
  the reconstruction buffer will have the deblocked pixels. We only need the
  edge-pixels for intra prediction though so we just save those.

- Right now it only copies the pixels and passes them on to search, where
  the copied pixels are asserted to be the same ones we copy from
  reconstruction buffer.

- New yuv_t struct added for arrays of dynamic length. We might want to change
  other buffers to use it or something like it in the future.
