Class MPEG4EncoderBlock

Namespace

VisioForge.Core.MediaBlocks.VideoEncoders

Assembly

VisioForge.Core.dll

MPEG-4 video encoder block for efficient video compression with advanced features and scalability. This block provides MPEG-4 Part 2 encoding capabilities offering improved compression efficiency compared to MPEG-2 with support for advanced features like object-based coding, scalability, and error resilience. Features configurable quality settings, motion estimation algorithms, and rate control modes. Essential for streaming applications, mobile video, and scenarios requiring flexible video compression with moderate bandwidth requirements. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

Constructors

MPEG4EncoderBlock(MPEG4VideoEncoderSettings)

Initializes a new instance of the VisioForge.Core.MediaBlocks.VideoEncoders.MPEG4EncoderBlock class with specified MPEG-4 encoder settings.

public MPEG4EncoderBlock(MPEG4VideoEncoderSettings settings)

Parameters

settings MPEG4VideoEncoderSettings

The MPEG-4 encoder configuration settings.

Properties

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

Methods

Build()

Constructs and initializes the MPEG-4 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 efficient video compression with advanced features and scalability.

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 MPEG-4 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 MPEG-4 encoder element.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper instance that encapsulates the GStreamer MPEG-4 encoder.

GetElement()

Gets the underlying GStreamer element that performs the MPEG-4 video encoding.

public Element GetElement()

Returns

Element

The GStreamer Element instance representing the MPEG-4 encoder.

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 MPEG-4 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.
