Class FLACEncoderBlock

Namespace

VisioForge.Core.MediaBlocks.AudioEncoders

Assembly

VisioForge.Core.dll

MediaBlock that encodes raw audio into FLAC (Free Lossless Audio Codec) format. FLAC is a lossless audio compression format that reduces file size without quality loss, making it ideal for archival storage, high-quality audio production, and applications where audio fidelity is critical. Supports configurable compression levels and encoding parameters. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals.

Constructors

FLACEncoderBlock(FLACEncoderSettings)

Initializes a new instance of the VisioForge.Core.MediaBlocks.AudioEncoders.FLACEncoderBlock class with the specified encoding settings.

public FLACEncoderBlock(FLACEncoderSettings settings)

Parameters

settings FLACEncoderSettings

The FLAC encoder settings that define compression level, quality parameters, and encoding behavior.

Properties

Input

Gets the single audio input pad for this encoder block.

public override MediaBlockPad Input { get; }

Property Value

MediaBlockPad

Inputs

Gets all input pads for this encoder block.

public override MediaBlockPad[] Inputs { get; }

Property Value

MediaBlockPad[]

Output

Gets the single audio output pad for this encoder block.

public override MediaBlockPad Output { get; }

Property Value

MediaBlockPad

Outputs

Gets all output pads for this encoder block.

public override MediaBlockPad[] Outputs { get; }

Property Value

MediaBlockPad[]

Settings

Gets or sets the FLAC encoder settings that control compression level, quality parameters, and encoding behavior. These settings determine the balance between file size and encoding speed.

public FLACEncoderSettings Settings { get; set; }

Property Value

FLACEncoderSettings

Type

Gets the MediaBlock type identifier for this encoder.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

Methods

Build()

Constructs and initializes the FLAC encoder and its associated GStreamer elements. This method creates the encoder with the specified settings, establishes input and output pads, and prepares the block for lossless audio encoding.

public override bool Build()

Returns

bool

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

CleanUp()

Releases all resources and performs cleanup operations for this FLAC encoder 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 FLAC encoder element.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper instance that encapsulates the GStreamer FLAC encoder.

GetElement()

Gets the underlying GStreamer element that performs the FLAC encoding.

public Element GetElement()

Returns

Element

The GStreamer Element instance representing the FLAC encoder.

IsAvailable()

Determines whether the FLAC encoder is available on the current system. This checks if the required GStreamer FLAC encoder plugin is installed and accessible. The correct NuGet SDK redistribution package should be included in your project.

public static bool IsAvailable()

Returns

bool

true if the FLAC encoder is available and can be used; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Associates this FLAC encoder 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.
