@Generated("io.github.jwharm.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 proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

VideoFilter

public VideoFilter(Object... propertyNamesAndValues)

Creates a new VideoFilter with the provided property names and values.

Parameters:

propertyNamesAndValues - pairs of property names and values (Strings and Objects). Does not need to be null-terminated.

Throws:

IllegalArgumentException - invalid property names or values

Method Details

getType

public static 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()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class BaseTransform

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
