Class GLFlipBlock

Namespace

VisioForge.Core.MediaBlocks.OpenGL

Assembly

VisioForge.Core.dll

OpenGL-accelerated video flip transformation block for horizontal and vertical mirroring operations. Provides GPU-accelerated flipping capabilities including horizontal flip (mirror), vertical flip, and combined transformations for creating mirror effects and correcting camera orientations. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

Constructors

GLFlipBlock(GLFlipVideoEffect)

Initializes a new instance of the VisioForge.Core.MediaBlocks.OpenGL.GLFlipBlock class with the specified flip transformation settings. Creates the necessary input and output pads for video processing with the configured flip operations.

public GLFlipBlock(GLFlipVideoEffect settings)

Parameters

settings GLFlipVideoEffect

The flip effect settings that define the transformation parameters.

Properties

Input

Gets the primary input pad for receiving video frames to be transformed.

public override MediaBlockPad Input { get; }

Property Value

MediaBlockPad

Inputs

Gets all input pads available on this block (single input for video processing).

public override MediaBlockPad[] Inputs { get; }

Property Value

MediaBlockPad[]

Output

Gets the primary output pad for providing flipped video frames.

public override MediaBlockPad Output { get; }

Property Value

MediaBlockPad

Outputs

Gets all output pads available on this block (single output for processed video).

public override MediaBlockPad[] Outputs { get; }

Property Value

MediaBlockPad[]

Settings

Gets or sets the flip transformation settings that control the type and direction of the flip operation.

public GLFlipVideoEffect Settings { get; set; }

Property Value

GLFlipVideoEffect

Type

Gets the media block type identifier for OpenGL flip operations.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

Methods

Build()

Builds and initializes the OpenGL flip transformation block within the pipeline context. Creates the GStreamer flip filter, applies the transformation settings, and establishes the necessary pad connections for processing video frames with the specified flip operations.

public override bool Build()

Returns

bool

true if the flip transformation block was successfully built and configured; otherwise, false.

CleanUp()

Cleans up all resources associated with the OpenGL flip transformation, including GStreamer elements and GPU shader programs.

public void CleanUp()

Dispose(bool)

Releases unmanaged and managed resources used by the OpenGL flip transformation block. Properly disposes of GStreamer elements and GPU transformation 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 element wrapper for advanced configuration and monitoring.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper providing access to the underlying GStreamer flip filter.

GetElement()

Gets the native GStreamer element for direct GStreamer pipeline integration.

public Element GetElement()

Returns

Element

The native Gst.Element representing the flip transformation filter.

IsAvailable()

Determines whether OpenGL flip transformation functionality is available on the current system. Requires OpenGL support and appropriate GStreamer OpenGL transformation plugins to be installed.

public static bool IsAvailable()

Returns

bool

true if flip transformation operations are supported; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Sets the pipeline context for this OpenGL flip transformation block, providing access to the parent pipeline and logging context.

void IMediaBlockInternals.SetContext(MediaBlocksPipeline pipeline)

Parameters

pipeline MediaBlocksPipeline

The parent MediaBlocks pipeline containing this flip transformation block.
