MediaFormat.QpOffsetRect
extends Object
QpOffsetRect constitutes the metadata required for encoding a region of interest in an
image or a video frame. The region of interest is represented by a rectangle. The four
integer coordinates of the rectangle are stored in fields left, top, right, bottom.
Note that the right and bottom coordinates are exclusive.
This is paired with a suggestive qp offset information that is to be used during encoding
of the blocks belonging to the to the box.

Public constructors
QpOffsetRect
public QpOffsetRect (Rect contour,
int qpOffset)
Create a new region of interest with the specified coordinates and qpOffset. Note: no
range checking is performed, so the caller must ensure that left >= 0, left <= right,
top >= 0 and top <= bottom. Note that the right and bottom coordinates are exclusive.
Parameters |
contour |
Rect : Rectangle specifying the region of interest
This value cannot be null . |
qpOffset |
int : qpOffset to be used for the blocks in the specified rectangle |
Public methods
flattenToString
public String flattenToString ()
set
public void set (Rect contour,
int qpOffset)
Update the region of interest information with the specified coordinates and qpOffset
Parameters |
contour |
Rect : Rectangle specifying the region of interest
This value cannot be null . |
qpOffset |
int : qpOffset to be used for the blocks in the specified rectangle |
