Constructor Details

ProxyPad

public ProxyPad(MemorySegment address)

Create a ProxyPad proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

ProxyPad

public ProxyPad()

Creates a new ProxyPad.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the ProxyPad class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected ProxyPad 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 Pad

chainDefault

public static FlowReturn chainDefault(Pad pad,
 @Nullable GstObject parent,
 Buffer buffer)

Invoke the default chain function of the proxy pad.

Parameters:

pad - a sink GstPad, returns GST_FLOW_ERROR if not.

parent - the parent of pad or null

buffer - the GstBuffer to send, return GST_FLOW_ERROR if not.

Returns:

a GstFlowReturn from the pad.

chainListDefault

public static FlowReturn chainListDefault(Pad pad,
 @Nullable GstObject parent,
 BufferList list)

Invoke the default chain list function of the proxy pad.

Parameters:

pad - a sink GstPad, returns GST_FLOW_ERROR if not.

parent - the parent of pad or null

list - the GstBufferList to send, return GST_FLOW_ERROR if not.

Returns:

a GstFlowReturn from the pad.

getrangeDefault

public static FlowReturn getrangeDefault(Pad pad,
 GstObject parent,
 long offset,
 int size,
 Out<Buffer> buffer)

Invoke the default getrange function of the proxy pad.

Parameters:

pad - a src GstPad, returns GST_FLOW_ERROR if not.

parent - the parent of pad

offset - The start offset of the buffer

size - The length of the buffer

buffer - a pointer to hold the GstBuffer, returns GST_FLOW_ERROR if null.

Returns:

a GstFlowReturn from the pad.

iterateInternalLinksDefault

public static @Nullable Iterator iterateInternalLinksDefault(Pad pad,
 @Nullable GstObject parent)

Invoke the default iterate internal links function of the proxy pad.

Parameters:

pad - the GstPad to get the internal links of.

parent - the parent of pad or null

Returns:

a GstIterator of GstPad, or null if pad has no parent. Unref each returned pad with gst_object_unref().

getInternal

public @Nullable ProxyPad getInternal()

Get the internal pad of pad. Unref target pad after usage.

The internal pad of a GstGhostPad is the internally used pad of opposite direction, which is used to link to the target.

Returns:

the target GstProxyPad, can be null. Unref target pad after usage.

builder

public static ProxyPad.Builder<? extends ProxyPad.Builder> builder()

A ProxyPad.Builder object constructs a ProxyPad with the specified properties. Use the various set...() methods to set properties, and finish construction with ProxyPad.Builder.build().

Returns:

the builder object
