public class DiscovererStreamInfo
extends GObject

Base structure for information concerning a media stream. Depending on the stream type, one can find more media-specific information in GstDiscovererAudioInfo, GstDiscovererVideoInfo, and GstDiscovererContainerInfo.

The GstDiscovererStreamInfo represents the topology of the stream. Siblings can be iterated over with gst_discoverer_stream_info_get_next() and gst_discoverer_stream_info_get_previous(). Children (sub-streams) of a stream can be accessed using the GstDiscovererContainerInfo API.

As a simple example, if you run GstDiscoverer on an AVI file with one audio and one video stream, you will get a GstDiscovererContainerInfo corresponding to the AVI container, which in turn will have a GstDiscovererAudioInfo sub-stream and a GstDiscovererVideoInfo sub-stream for the audio and video streams respectively.

Constructor Details

DiscovererStreamInfo

public DiscovererStreamInfo(MemorySegment address)

Create a DiscovererStreamInfo proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

DiscovererStreamInfo

public DiscovererStreamInfo()

Creates a new DiscovererStreamInfo.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the DiscovererStreamInfo class

Returns:

the GType

asParent

protected DiscovererStreamInfo 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 GObject

listFree

public static void listFree(List<DiscovererStreamInfo> infos)

Decrements the reference count of all contained GstDiscovererStreamInfo and fress the GList.

Parameters:

infos - a GList of GstDiscovererStreamInfo

getCaps

public @Nullable Caps getCaps()

getMisc

@Deprecated
public @Nullable Structure getMisc()

Deprecated.

getNext

public @Nullable DiscovererStreamInfo getNext()

getPrevious

public @Nullable DiscovererStreamInfo getPrevious()

getStreamId

public @Nullable String getStreamId()

getStreamNumber

public int getStreamNumber()

getStreamTypeNick

public String getStreamTypeNick()

getTags

public @Nullable TagList getTags()

getToc

public @Nullable Toc getToc()

builder

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

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

Returns:

the builder object
