## Detailed Description

Encoder config related to the coding of key frames.

## Field Documentation

## key_freq_min

int KeyFrameCfg::key_freq_min

Indicates the minimum distance to a key frame.

Referenced by define_kf_interval().

## key_freq_max

int KeyFrameCfg::key_freq_max

Indicates the maximum distance to a key frame.

Referenced by av1_encode_strategy(), define_kf_interval(), and find_next_key_frame().

## enable_keyframe_filtering

int KeyFrameCfg::enable_keyframe_filtering

Indicates if temporal filtering should be applied on keyframe.

Referenced by av1_tf_do_filtering_row().

## sframe_dist

int KeyFrameCfg::sframe_dist

Indicates the number of frames after which a frame may be coded as an S-Frame.

Referenced by encode_frame_to_data_rate().

## sframe_mode

int KeyFrameCfg::sframe_mode

Indicates how an S-Frame should be inserted. 1: the considered frame will be made into an S-Frame only if it is an altref frame. 2: the next altref frame will be made into an S-Frame.

## auto_key

bool KeyFrameCfg::auto_key

Indicates if encoder should autodetect cut scenes and set the keyframes.

Referenced by define_kf_interval(), and find_next_key_frame().

## fwd_kf_dist

int KeyFrameCfg::fwd_kf_dist

Indicates the forward key frame distance.

Referenced by av1_get_second_pass_params().

## fwd_kf_enabled

bool KeyFrameCfg::fwd_kf_enabled

Indicates if forward keyframe reference should be enabled.

## enable_sframe

bool KeyFrameCfg::enable_sframe

Indicates if S-Frames should be enabled for the sequence.

## enable_intrabc

bool KeyFrameCfg::enable_intrabc

Indicates if intra block copy prediction mode should be enabled or not.

Referenced by encode_frame_internal(), and rd_pick_intrabc_mode_sb().
