Class MovingEchoBlock

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

Moving echo effect block that creates ghosting trails and echo images of moving objects. This block analyzes motion between frames to detect moving elements and generates visual echo trails that follow the movement path. Features configurable echo intensity, trail length, and fade parameters for creating dynamic motion-tracking visual effects. Essential for artistic video production, motion visualization, sports analysis, and creative effects requiring motion trail emphasis. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

MovingEchoBlock(MovingEchoVideoEffect)

Initializes a new instance of the VisioForge.Core.MediaBlocks.VideoProcessing.MovingEchoBlock class with specified moving echo effect settings.

public MovingEchoBlock(MovingEchoVideoEffect settings)

Parameters

settings MovingEchoVideoEffect

The moving echo effect 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 or sets the moving echo effect settings. Contains parameters for controlling echo trail intensity, length, fade characteristics, and motion detection sensitivity for dynamic echo generation.

public MovingEchoVideoEffect Settings { get; set; }

Property Value

MovingEchoVideoEffect

Type

Gets the type.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

Methods

Build()

Constructs and initializes the moving echo filter and its associated GStreamer elements. This method creates the filter with the specified settings, establishes input and output pads, and prepares the block for generating ghosting trails that follow moving objects in the video.

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 moving echo effect 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 moving echo filter element.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper instance that encapsulates the GStreamer moving echo filter.

GetElement()

Gets the underlying GStreamer element that performs the motion echo trail processing.

public Element GetElement()

Returns

Element

The GStreamer Element instance representing the moving echo 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 moving echo effect 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.
