QpOffsetRect

class QpOffsetRect
kotlin.Any
   ↳ 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.

QpOffsetRect

Added in API level 35
QpOffsetRect(
    contour: Rect, 
    qpOffset: Int)

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

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

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

set

Added in API level 35
fun set(
    contour: Rect, 
    qpOffset: Int
