MediaFormat.QpOffsetRect

Kotlin |Java

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.

Public constructors

QpOffsetRect

Added in Android VanillaIceCream

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 Android VanillaIceCream

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 Android VanillaIceCream

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 Android VanillaIceCream

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
