@Generated("org.javagi.JavaGI")
public abstract class VideoFilter
extends BaseTransform

Provides useful functions and a base class for video filters.

The videofilter will by default enable QoS on the parent GstBaseTransform to implement frame dropping.

Constructor Details

VideoFilter

public VideoFilter(MemorySegment address)

Create a VideoFilter instance for the provided memory address.

Parameters:

address - the memory address of the native object

VideoFilter

public VideoFilter()

Create a new VideoFilter.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the VideoFilter class.

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected VideoFilter asParent()

Return this instance as if it were its parent type. Comparable to the Java super keyword, but ensures the parent typeclass is also used in native code.

Overrides:

asParent in class BaseTransform

Returns:

the instance as if it were its parent type

setInfo

protected boolean setInfo(Caps incaps,
 VideoInfo inInfo,
 Caps outcaps,
 VideoInfo outInfo)

function to be called with the negotiated caps and video infos

transformFrame

protected FlowReturn transformFrame(VideoFrame inframe,
 VideoFrame outframe)

transform a video frame

transformFrameIp

protected FlowReturn transformFrameIp(VideoFrame frame)

transform a video frame in place
