Class InterlaceBlock

Namespace
VisioForge.Core.MediaBlocks.VideoProcessing
Assembly
VisioForge.Core.dll

Interlace block for converting progressive video content to interlaced format. This block applies interlacing effects to progressive video content by combining alternating scan lines to create traditional broadcast-compatible interlaced video. Features configurable field order, pattern selection, and temporal processing for creating authentic interlaced output. Essential for broadcast delivery, legacy system compatibility, and creating specific visual effects that require interlaced video characteristics for technical or artistic purposes. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

Extension Methods

Constructors

InterlaceBlock(InterlaceSettings)

Initializes a new instance of the VisioForge.Core.MediaBlocks.VideoProcessing.InterlaceBlock class with specified interlacing settings.

public InterlaceBlock(InterlaceSettings settings)

Parameters

settings InterlaceSettings

The interlacing configuration settings.

Properties

Input

Gets the input.

public override MediaBlockPad Input { get; }

Property Value

MediaBlockPad

Inputs

Gets the inputs.

public override MediaBlockPad[] Inputs { get; }

Property Value

MediaBlockPad[]

Output

Gets the output.

public override MediaBlockPad Output { get; }

Property Value

MediaBlockPad

Outputs

Gets the outputs.

public override MediaBlockPad[] Outputs { get; }

Property Value

MediaBlockPad[]

Settings

Gets the interlacing settings. Contains parameters for controlling field order, scan line patterns, and temporal processing for progressive-to-interlaced conversion.

public InterlaceSettings Settings { get; }

Property Value

InterlaceSettings

Type

Gets the type.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

Methods

Build()

Constructs and initializes the interlace filter and its associated GStreamer elements. This method creates the filter with the specified interlacing settings, establishes input and output pads, and prepares the block for converting progressive video to interlaced format for broadcast compatibility.

public override bool Build()

Returns

bool

true if the filter was successfully built and configured; false if initialization failed.

CleanUp()

Releases all resources and performs cleanup operations for this interlace block. This method disposes of the GStreamer elements and resets the build state.

public void CleanUp()

Dispose(bool)

Releases unmanaged and - optionally - managed resources.

protected override void Dispose(bool disposing)

Parameters

disposing bool

true to release both managed and unmanaged resources; false to release only unmanaged resources.

GetCore()

Gets the core BaseElement wrapper that provides additional functionality around the GStreamer interlace filter element.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper instance that encapsulates the GStreamer interlace filter.

GetElement()

Gets the underlying GStreamer element that performs the interlacing processing.

public Element GetElement()

Returns

Element

The GStreamer Element instance representing the interlace filter.

IsAvailable()

Determines whether this media block is available. Correct NuGet SDK redist should be included into your project.

public static bool IsAvailable()

Returns

bool

true if this media block is available; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Associates this interlace block with a pipeline and initializes its internal context. This method is called internally when the block is added to a pipeline.

void IMediaBlockInternals.SetContext(MediaBlocksPipeline pipeline)

Parameters

pipeline MediaBlocksPipeline

The MediaBlocksPipeline instance that will manage this block.
