- 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.
The transform skip flag in cu_info_t was stored under the intra
substruct even though transform skip can be used for inter as well. This
caused bitstream errors. Fixed by moving the flag out of the substruct.
Moves duplicate code for writing the MVD of a single motion vector from
kvz_get_mvd_coding_cost_cabac and encoder_inter_prediction_unit to a new
function.
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.
Sets max_transform_hierarchy_depth_inter to 0 in SPS. This saves some
bits because split_transform_flag does not need to be coded for inter
blocks.
When SMP and AMP blocks are enabled the depth is set to 1 instead.
Otherwise inter split flag would default to 1 for SMP and AMP blocks,
resulting in an unnecessary transform split.
Changes functions encode_intra_coding_unit and encode_coding_tree to
take coordinate arguments in units of luma pixels instead of 8 px
blocks. This should make the code easier to understand.
Changes functions encode_transform_unit and encode_transform_coeff to
take coordinate arguments in units of luma pixels instead of 4 px
blocks. This should make the code easier to understand.
A CryptoPP::CFB_Mode<CryptoPP::AES>::Encryption was allocated at the
beginning of encoder_state_encode_leaf and was never freed. This commit
changes encoder_state_worker_encode_lcu to delete the CFB_Mode. Also
moves crypto handle from encoder_state_config_tile_t to encoder_state_t
so that it can be safely deleted without affecting other threads in the
same tile.
Moves the inline declaration of intra_mode_encryption before the type
and changes it to use the INLINE macro. Inline declaration after type
triggered a warning on GCC.
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.
