org.freedesktop.gstreamer.gst.CustomMeta

All Implemented Interfaces:

Proxy

@Generated("io.github.jwharm.JavaGI")
public class CustomMeta
extends ProxyInstance

Extra custom metadata. The structure field is the same as returned by gst_custom_meta_get_structure().

Since 1.24 it can be serialized using gst_meta_serialize() and gst_meta_deserialize(), but only if the GstStructure does not contain any fields that cannot be serialized, see SerializeFlags.STRICT.

Since:

1.20

Constructor Summary

Constructors

Constructor	Description
CustomMeta()	Allocate a new CustomMeta.
CustomMeta(Arena arena)	Allocate a new CustomMeta.
CustomMeta(MemorySegment address)	Create a CustomMeta proxy instance for the provided memory address.
CustomMeta(Meta meta, Structure structure)	Allocate a new CustomMeta with the fields set to the provided values.

Method Summary

Modifier and Type	Method	Description
static MemoryLayout	getMemoryLayout()	The memory layout of the native struct.
Structure	getStructure()	Retrieve the GstStructure backing a custom meta, the structure's mutability is conditioned to the writability of the GstBuffer this CustomMeta is attached to.

Constructor Details

CustomMeta

public CustomMeta(MemorySegment address)

Create a CustomMeta proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

CustomMeta

public CustomMeta(Arena arena)

Allocate a new CustomMeta.

Parameters:

arena - to control the memory allocation scope

CustomMeta

public CustomMeta()

Allocate a new CustomMeta. The memory is allocated with Arena.ofAuto().

CustomMeta

public CustomMeta(Meta meta,
 Structure structure,
 Arena arena)

Allocate a new CustomMeta with the fields set to the provided values.

Parameters:

meta - value for the field meta

structure - value for the field structure

arena - to control the memory allocation scope

CustomMeta

public CustomMeta(Meta meta,
 Structure structure)

Allocate a new CustomMeta with the fields set to the provided values. The memory is allocated with Arena.ofAuto().

Parameters:

meta - value for the field meta

structure - value for the field structure

Method Details

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

readMeta

public @Nullable Meta readMeta()

Read the value of the field meta.

Returns:

The value of the field meta

writeMeta

public void writeMeta(@Nullable Meta meta)

Write a value in the field meta.

Parameters:

meta - The new value for the field meta

readStructure

public Structure readStructure()

Read the value of the field structure.

Returns:

The value of the field structure

writeStructure

public void writeStructure(Structure structure)

Write a value in the field structure.

Parameters:

structure - The new value for the field structure

getStructure

public Structure getStructure()

Retrieve the GstStructure backing a custom meta, the structure's mutability is conditioned to the writability of the GstBuffer this CustomMeta is attached to.

Returns:

the GstStructure backing this CustomMeta

Since:

1.20

hasName

public boolean hasName(String name)

Checks whether the name of the custom meta is name

Returns:

Whether name is the name of the custom meta

Since:
