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.
 2018-06-13 15:36:19 +03:00
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.
 2018-01-29 12:41:56 +02:00
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.

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 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 9395867a9a Quantize all colors in a single traversal 
Changes kvz_quantize_lcu_residual to process all three colors in
a single traversal of the TU tree.

Arttu Ylä-Outinen cc87e0dcc7 Combine luma and chroma quantization functions 
Replaces functions kvz_quantize_lcu_luma_residual and
kvz_quantize_lcu_chroma_residual in transform.c with function
kvz_quantize_lcu_residual. The new function can handle any of the YUV
colors. Removes some duplicated code.

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.

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

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.

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.

The SSD is always zero since it is lossless.

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.

Arttu Ylä-Outinen 2ae260e422 Change width of cells in lcu_t to 4 pixels.
