Arttu Ylä-Outinen ebddd854dc Fix clobbered warnings in tests 
Adds volatile to loop variables in kvazaar tests in order to fix "might
be clobbered by ‘longjmp’ or ‘vfork’" warnings when building with -O3.

Arttu Ylä-Outinen 4b73bdd9aa Skip checked motion vectors in early termination 
Changes the second iteration of early termination to skip the motion
vectors that were already checked in the first iteration.

Arttu Ylä-Outinen 606d441362 Skip computing MV cost twice in hexagon search 
Changes the first step of hexagon search to skip the zero offset since
the cost of the motion vector has already been computed.

Arttu Ylä-Outinen fa4648061d Add mv, cost and bitcost to inter_search_info_t 2017-08-09 14:29:08 +03:00
Arttu Ylä-Outinen 328f051d7f Put inter search parameters in a single struct 
Adds struct inter_search_info_t for holding the parameters that are used
by most function related to inter search. Passing the parameters in
a single struct greatly reduces the number of parameters for many
functions.

Arttu Ylä-Outinen 24ecddd2a5 Fix wrong strides in SAO reconstruction 
Functions kvz_sao_reconstruct and encoder_sao_reconstruct used
frame->width as the stride instead of frame->rec->stride when accessing
frame->rec->data. This caused errors when using tiles and SAO.

Arttu Ylä-Outinen f0bf959d17 Fix alignment errors in 32-bit build with MSVC 
Changes the work_tree parameter in search.c functions from an array to
a pointer. Fixes "formal parameter with requested alignment of 8 won't
be aligned" errors.
 2017-07-28 09:27:02 +03:00
Arttu Ylä-Outinen 9694bd2fae Fix build on 32-bit systems 
Function coeff_abs_sum_avx2 that was added in e950c9b was outside the
AVX2 #if directive.

Arttu Ylä-Outinen ecb0275cdd Store CU arrays as pointers to the main array 
Changes field state->tile->frame->cu_array->data to point to the CU
array in the main encoder state. Removes the need to copy the CU array
to the main CU array after search.

Reduces intra threshold for --rd=0 from 20 to 8. Threshold of 20
increased BD-Rate too much.

Arttu Ylä-Outinen e9cf15465e Fix inter cost in bipred 
The cost of coding MV ref indices and MV direction was added to bitcost
but not inter cost. Fixed by adding the extra bits to inter as well.

Arttu Ylä-Outinen edbe00763e Drop extra parameter in kvz_image_calc_sad 
Drops the parameter max_lcu_below which was always set to -1.

Arttu Ylä-Outinen 631ef53d2a Fix inter cost calculations 
Inter costs are computed using SAD except when fractional motion
estimation or bi-prediction is enabled. This commit changes
search_pu_inter_ref to recalculate the cost with SATD. Fixes inter/intra
cost comparisons since intra costs are always SATD costs.

Arttu Ylä-Outinen 2380ba0d41 Reduce copying in kvz_get_coeff_cost 
Changes function kvz_get_coeff_cost to only copy the CABAC contexts and
not the whole encoder state.

Other threads could be simultaneously using the other parts of the
encoder state. Only copying the CABAC fixes a TSan data race warning.

Arttu Ylä-Outinen 24b462f801 Align coefficients to 8 bytes 
Adds alignment attribute to lcu_coeff_t. The coefficients are sometimes
handled as 64-bit integers containing four coefficients so the arrays
should be aligned to 8 bytes.

Fixes a UBSan error about misaligned reads.

Arttu Ylä-Outinen 5ddb43c6fe Fix undefined left shifts in rdo 
Replaces left shifts by multiplications when the operand may be
a negative value. Left shift of a negative value is undefined behavior.

Arttu Ylä-Outinen 07b5fb9caf Fix out-of-bounds read in encoderstate 
When calling encoder_state_encode_leaf with POC 0, index -1 of the GOP
array would be accessed. Fixed by skipping the code for I-frames.
 2017-07-20 11:15:30 +03:00
Arttu Ylä-Outinen 8c4a3473a8 Change --owf=auto and --threads=auto selection 
Changes OWF selection so that it is chosen based on the maximum number
of parallel CTUs. Number of threads is limited to prevent overhead from
extra threads.
 2017-07-20 09:42:28 +03:00
Arttu Ylä-Outinen 4fc9b743c1 Drop an unnecessary pthread_cond_broadcast 
Drop pthread_cond_broadcast on threadqueue->cond in function
kvz_threadqueue_waitfor. The broadcast caused threads to be woken up
more often than necessary.

Arttu Ylä-Outinen e90bde5c62 Clarify PSNR output 
Adds letters Y, U and V to the PSNR output to make it clearer that the
printed values are the luma and chroma PSNR.

Arttu Ylä-Outinen 67a60a35e3 Fix invalid calls to normalize_lcu_weights 
Changes encoder_state_init_new_frame to only call normalize_lcu_weights
when the weights have been written to the array and rate control is
enabled. When rate control is disabled, the weights are not used.

Arttu Ylä-Outinen 563bc26e71 Fix out-of-bounds read in AVX2 SAO

are only five 32 bit integers.
