Detailed Description

Algorithm configuration parameters.

Field Documentation

◆ sharpness

int AlgoCfg::sharpness

Controls the level at which rate-distortion optimization of transform coefficients favours sharpness in the block. Has no impact on RD when set to zero (default). For values 1-7, eob and skip block optimization are avoided and rdmult is adjusted in favour of block sharpness.

◆ disable_trellis_quant

int AlgoCfg::disable_trellis_quant

Indicates the trellis optimization mode of quantized coefficients. 0: disabled 1: enabled 2: enabled for rd search 3: true for estimate yrd search

◆ arnr_max_frames

int AlgoCfg::arnr_max_frames

The maximum number of frames used to create an arf.

Referenced by av1_get_second_pass_params(), and tf_setup_filtering_buffer().

◆ arnr_strength

int AlgoCfg::arnr_strength

The temporal filter strength for arf used when creating ARFs.

Referenced by av1_tf_do_filtering_row().

◆ cdf_update_mode

uint8_t AlgoCfg::cdf_update_mode

Indicates the CDF update mode 0: no update 1: update on every frame(default) 2: selectively update

Referenced by encode_frame_to_data_rate().

◆ enable_tpl_model

bool AlgoCfg::enable_tpl_model

Indicates if RDO based on frame temporal dependency should be enabled.

Referenced by av1_get_second_pass_params(), av1_rd_pick_inter_mode(), and setup_delta_q().

◆ enable_overlay

bool AlgoCfg::enable_overlay

Indicates if coding of overlay frames for filtered ALTREF frames is enabled.

◆ loopfilter_control

LOOPFILTER_CONTROL AlgoCfg::loopfilter_control

Controls loop filtering 0: Loop filter is disabled for all frames 1: Loop filter is enabled for all frames 2: Loop filter is disabled for non-reference frames 3: Loop filter is disables for the frames with low motion

◆ skip_postproc_filtering

bool AlgoCfg::skip_postproc_filtering

Indicates if the application of post-processing filters should be skipped on reconstructed frame.
