Extension Methods

Remarks

The LibVisual LV Analyzer visualizer creates analyzer-style frequency spectrum displays:

  • Traditional spectrum analyzer with frequency bars
  • Real-time frequency distribution visualization
  • Classic audio analyzer interface with frequency bands
  • Professional-style frequency analysis display This visualization provides a technical and precise representation of audio frequency content.

Constructors

LibVisualLVAnalyzerBlock()

Initializes a new instance of the VisioForge.Core.MediaBlocks.AudioVisualizers.LibVisualLVAnalyzerBlock class.

public LibVisualLVAnalyzerBlock()

Remarks

Creates a libvisual LV analyzer block with default settings. The block accepts audio input and produces video output showing the analyzer visualization with frequency spectrum display.

Properties

Input

Gets the primary input pad for audio data.

public override MediaBlockPad Input { get; }

Property Value

MediaBlockPad

Inputs

Gets all input pads available on this block.

public override MediaBlockPad[] Inputs { get; }

Property Value

MediaBlockPad[]

Output

Gets the primary output pad for video data.

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[]

Type

Gets the media block type.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

Methods

Build()

Builds and initializes the analyzer visualization block.

public override bool Build()

Returns

bool

true if the block was successfully built and configured; false if an error occurred.

Remarks

This method creates the underlying GStreamer libvisual LV analyzer elements, and establishes the input/output pads for audio/video data flow.

CleanUp()

Cleans up and releases all resources used by the LV analyzer block.

public void CleanUp()

Remarks

This method disposes of the underlying GStreamer elements and resets the build state.

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 GStreamer base element wrapped by this block.

public BaseElement GetCore()

Returns

BaseElement

The underlying VisioForge.Core.GStreamer.Base.BaseElement instance.

GetElement()

Gets the raw GStreamer element for advanced manipulation.

public Element GetElement()

Returns

Element

The native GStreamer Gst.Element instance.

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)

Sets the media pipeline context for this block.

void IMediaBlockInternals.SetContext(MediaBlocksPipeline pipeline)

Parameters

pipeline MediaBlocksPipeline

The parent media pipeline that will contain this block.
