MediaFormat.QpOffsetRect


public static final class MediaFormat.QpOffsetRect
extends Object

java.lang.Object
   ↳ android.media.MediaFormat.QpOffsetRect


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.

Summary

Public constructors

QpOffsetRect(Rect contour, int qpOffset)

Create a new region of interest with the specified coordinates and qpOffset.

Public methods

String flattenToString()
static String flattenToString(List<MediaFormat.QpOffsetRect> qpOffsetRects)
void set(Rect contour, int qpOffset)

Update the region of interest information with the specified coordinates and qpOffset

Inherited methods

Public constructors

QpOffsetRect

Added in API level 35
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

Added in API level 35
public String flattenToString ()

Returns
String Return a string representation of qpOffsetRect in a compact form. Helper function to insert key ERROR(/#PARAMETER_KEY_QP_OFFSET_RECTS) in MediaFormat This value cannot be null.

flattenToString

Added in API level 35
public static String flattenToString (List<MediaFormat.QpOffsetRect> qpOffsetRects)

Parameters
qpOffsetRects List: This value cannot be null.

Returns
String Return a string representation of qpOffsetRect in a compact form. Helper function to insert key ERROR(/#PARAMETER_KEY_QP_OFFSET_RECTS) in MediaFormat This value cannot be null.

set

Added in API level 35
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
