## Detailed Description

Parameters related to global motion search.

## Field Documentation

## ◆ search_done

bool GlobalMotionInfo::search_done

Flag to indicate if global motion search needs to be rerun.

Referenced by encode_with_recode_loop().

## ◆ ref_buf

YV12_BUFFER_CONFIG* GlobalMotionInfo::ref_buf[REF_FRAMES]

Array of pointers to the frame buffers holding the reference frames. ref_buf[i] stores the pointer to the reference frame of the ith reference frame type.

## ◆ num_ref_frames

int GlobalMotionInfo::num_ref_frames[2]

Holds the number of valid reference frames in past and future directions w.r.t. the current frame. num_ref_frames[i] stores the total number of valid reference frames in 'i' direction.

## ◆ reference_frames

FrameDistPair GlobalMotionInfo::reference_frames[2][REF_FRAMES - 1]

Array of structure which stores the valid reference frames in past and future directions and their corresponding distance from the source frame. reference_frames[i][j] holds the jth valid reference frame type in the direction 'i' and its temporal distance from the source frame .

## ◆ segment_map_w

int GlobalMotionInfo::segment_map_w

segment map width

## ◆ segment_map_h

int GlobalMotionInfo::segment_map_h

segment map height
