Class FlipRotateBlock

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

MediaBlock that applies geometric transformations to video including flipping and rotation operations. This block provides horizontal flip, vertical flip, and rotation capabilities (90°, 180°, 270°) commonly used for correcting camera orientation, creating mirror effects, or adjusting video captured from mobile devices. The transformations are performed efficiently without quality loss. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

FlipRotateBlock(VideoFlipRotateMethod)

Initializes a new instance of the VisioForge.Core.MediaBlocks.VideoProcessing.FlipRotateBlock class with the specified geometric transformation method.

public FlipRotateBlock(VideoFlipRotateMethod settings)

Parameters

settings VideoFlipRotateMethod

The flip/rotate transformation method to apply to the video stream.

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 flip/rotate transformation method. Specifies the type of geometric transformation to apply including horizontal flip, vertical flip, and rotation operations (90°, 180°, 270°).

public VideoFlipRotateMethod Settings { get; set; }

Property Value

VideoFlipRotateMethod

Type

Gets the type.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

Methods

Build()

Constructs and initializes the flip/rotate transformation filter and its associated GStreamer elements. This method creates the filter with the specified transformation method, establishes input and output pads, and prepares the block for video geometric transformation processing.

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 flip/rotate transformation 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 flip/rotate filter element.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper instance that encapsulates the GStreamer flip/rotate filter.

GetElement()

Gets the underlying GStreamer element that performs the flip/rotate transformations.

public Element GetElement()

Returns

Element

The GStreamer Element instance representing the flip/rotate 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 flip/rotate transformation 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.
