Class ALAWEncoderBlock

Namespace
VisioForge.Core.MediaBlocks.AudioEncoders
Assembly
VisioForge.Core.dll

MediaBlock that encodes raw audio into A-law (G.711) format. A-law is a standard audio compression algorithm widely used in European telecommunications systems, providing 8-bit logarithmic quantization of 16-bit audio samples. This encoder is commonly used for telephony applications and VoIP systems where bandwidth efficiency is important. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

ALAWEncoderBlock()

Initializes a new instance of the VisioForge.Core.MediaBlocks.AudioEncoders.ALAWEncoderBlock class. Creates a new A-law encoder block with default settings suitable for standard telephony applications.

public ALAWEncoderBlock()

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[]

Type

Gets the MediaBlock type identifier for this encoder.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

Methods

Build()

Constructs and initializes the A-law encoder and its associated GStreamer elements. This method creates the encoder with standard A-law settings, establishes input and output pads, and prepares the block for media processing.

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 A-law 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 A-law encoder element.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper instance that encapsulates the GStreamer A-law encoder.

GetElement()

Gets the underlying GStreamer element that performs the A-law encoding.

public Element GetElement()

Returns

Element

The GStreamer Element instance representing the A-law encoder.

IsAvailable()

Determines whether the A-law encoder is available on the current system. This checks if the required GStreamer A-law 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 A-law encoder is available and can be used; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Associates this A-law 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.
