@Generated("org.javagi.JavaGI")
public class Stream
extends GstObject

A high-level object representing a single stream. It might be backed, or not, by an actual flow of data in a pipeline (GstPad).

A GstStream does not care about data changes (such as decoding, encoding, parsing,...) as long as the underlying data flow corresponds to the same high-level flow (ex: a certain audio track).

A GstStream contains all the information pertinent to a stream, such as stream-id, tags, caps, type, ...

Elements can subclass a GstStream for internal usage (to contain information pertinent to streams of data).

Constructor Details

Stream

public Stream(MemorySegment address)

Create a Stream instance for the provided memory address.

Parameters:

address - the memory address of the native object

Stream

public Stream(@Nullable String streamId,
 @Nullable Caps caps,
 Set<StreamType> type,
 Set<StreamFlags> flags)

Create a new GstStream for the given streamId, caps, type and flags

Parameters:

streamId - the id for the new stream. If null, a new one will be automatically generated

caps - the GstCaps of the stream

type - the GstStreamType of the stream

flags - the GstStreamFlags of the stream

Since:

1.10

Stream

public Stream(@Nullable String streamId,
 @Nullable Caps caps,
 StreamType type,
 StreamFlags... flags)

Create a new GstStream for the given streamId, caps, type and flags

Parameters:

streamId - the id for the new stream. If null, a new one will be automatically generated

caps - the GstCaps of the stream

type - the GstStreamType of the stream

flags - the GstStreamFlags of the stream

Since:

1.10

Stream

public Stream()

Create a new Stream.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the Stream class.

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected Stream 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 GstObject

Returns:

the instance as if it were its parent type

getCaps

Retrieve the current stream flags for this Stream

Returns:

The GstStreamFlags for this Stream

Since:

1.10

getStreamId

public @Nullable String getStreamId()

Returns the stream ID of stream.

Returns:

the stream ID of stream. Only valid during the lifetime of stream.
