Namespace
VisioForge.Core.MediaBlocks.Sources
Assembly
VisioForge.Core.dll

Blu-Ray disc source block for high-definition optical disc playback. Plays the main title, or a chosen one, of a Blu-Ray disc folder or image from its .m2ts stream, with audio track selection. Needs the GStreamer decodebin3, tsdemux and h264parse elements. Implements the VisioForge.Core.MediaBlocks.Sources.SourceMediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

public override MediaBlockPad[] Inputs { get; }

Property Value

MediaBlockPad[]

Output

public override MediaBlockPad Output { get; }

Property Value

MediaBlockPad

Outputs

Gets all output pads available on this block.

public override MediaBlockPad[] Outputs { get; }

Property Value

MediaBlockPad[]

SubtitleOutput

Gets the subtitle output pad that provides subtitle stream to downstream blocks.

public MediaBlockPad SubtitleOutput { get; }

Property Value

MediaBlockPad

Type

Gets the media block type identifier for Blu-Ray source operations.

public override MediaBlockType Type { get; }

MediaBlockPad

Methods

Build()

Builds and initializes the Blu-Ray source within the pipeline context. Reads the Blu-Ray stream file into decodebin3, sets up decoding, and prepares output pads.

public override bool Build()

Returns

bool

true if the Blu-Ray source was successfully built; otherwise, false.

CleanUp()

Cleans up all resources associated with the Blu-Ray source.

public void CleanUp()

Dispose(bool)

Releases resources used by the Blu-Ray source.

protected override void Dispose(bool disposing)

Parameters

disposing bool

true to release both managed and unmanaged resources.

GetCore()

Gets the core GStreamer element wrapper.

public BaseElement GetCore()

Returns

BaseElement

Always null for composite source blocks.

GetElement()

Gets the native GStreamer element for direct pipeline integration.

public Element GetElement()

Returns

Element

The decodebin3 element that decodes the Blu-Ray stream.

IsAvailable()

Determines whether Blu-Ray playback support is available on the current system.

public static bool IsAvailable()

Returns

bool

true if Blu-Ray support is available; otherwise, false.

IsSubtitlesAvailable()

Determines whether subtitle streams are available from the Blu-Ray disc.

public override bool IsSubtitlesAvailable()

Returns

bool

Always false: a Blu-ray's subtitles are PGS bitmaps, which the block does not deliver.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Sets the pipeline context for this source block.

void IMediaBlockInternals.SetContext(MediaBlocksPipeline pipeline)

Parameters

pipeline MediaBlocksPipeline

The parent MediaBlocks pipeline.
